The weather is hot, we are also considering the purchase of air conditioning, here first before the purchase of some of the precautions to share with you what is not enough to add: a: floor location: whether in the top floor (in the top floor, then the summer will be easy to absorb the sun). ps: if in the top floor, then choose the air conditioning should be in the original basis to choose a larger. Second: room layout: windows whether the afternoon solar direct sunlight to the home (afternoon solar heat, ultraviolet rays). Indoor corners are many. ps: if it is the west sun, too many corners should also choose a little bigger. Three: people: how many people at home, children or elderly. ps: the main thing is to analyze the flow of people in the home, the flow of people on the air conditioning cooling, heating need to be taken into account. Four: air conditioning utility area (popular version): 12 square = small 1 horsepower (23 machines) 16 square = 1 horsepower (25, 26 machines) 20-23 square = 1.5 horsepower (35 machines) 25-33 square = 2 horsepower (0 machines) 35-40 square = 2.5 horsepower (60 machines) 40-50 square = 3 horsepower (72 machines) This value is suitable for the general public conditions of use! Simple users, such as the above 1, 2, 3 and other conditions of the relative increase in the number of p air conditioning. Five: how to choose an air conditioner: air conditioner selection rather big than small (here the big error in half a p or so, equivalent to 12 square feet would have needed to buy a small 1p, but I live in the top floor. Then I have to buy at least 1p) In addition, the factors affecting the cooling capacity required for the room not only includes the size of the room, but also windows and doors, the direction of the facade, the number of occupants, electrical equipment, etc. is also an important influence. Six: air-conditioning parts of the current market: pipeline: air-conditioning hanging machine original packaging about 3 meters pipe, cabinet machine about 4 meters. (Mitsubishi Electric pipeline are more than one meter, i.e., 4 meters hanging, 5 meters cabinet). Bracket: now the manufacturer no bracket delivery, small stores have to send, the big stores sometimes need to spend money to buy. (Mitsubishi motors original packaging with the original bracket, Haier individual models with bracket). Seven: air conditioning installation conditions Usually this is very important, air conditioning is a semi-finished product, some conditions are not required to add money. Three points quality, seven points installation. So understand the installation conditions of air conditioning will also save a lot of time in our purchase to reduce unnecessary trouble. 1. bracket (in addition to Mitsubishi, Haier individual models have a bracket to send): If your neighborhood air conditioning location that does not need a bracket, if you need to hang the outside unit on the wall you need to buy. Depends on the situation of the big holidays will also be delivered in limited quantities. 2. Piping: In addition to the original packaging outside the pipeline are to spend money to buy. 3. Installation of outdoor unit: whether the outdoor unit can go out from the floor. Some friends home windows on the security net and welded, the outdoor unit can not get out of this need to hang down from upstairs. Caused by hanging people hanging machine fee. 4. wall hole: with the current understanding there is no free to play a one-time into the hole (that is, the professional perforator hit). Are free impact drill holes. 5. This is very important more than 2 horsepower cabinet are not plugged. (Because of the larger power need to install air safety switch) These are some of the basic things of the air conditioning also some things still depends on personal preference. So tired, to eat! Remind consumers to pay attention to the following matters in the purchase and use of air-conditioning products to minimize disputes. Tip 1: avoid buying peak air conditioning consumption peak mainly concentrated in July and August, during which businesses are often in a negative amount of work. Compared with the robust sales, transportation vehicles, installers are far from being able to meet, very likely to lead to the installation is not timely, after-sales service can not keep up. It is recommended that consumers try to avoid the peak buying season, early preparation. Tip 2: Avoid conceptual confusion, do not blindly pursue fashion Air conditioning market new products, photocatalysts, cold catalysts, oxygen bar, negative ions, nano-healthy air conditioning concepts are varied. It is understood that, in addition to light wave air conditioning, all the current "health air conditioning" have not passed the test of the national authority, manufacturers trumpeted a variety of concepts, a variety of features are not lack of water. Consumers in the purchase, to consider the performance of the product price ratio, should not blindly pursue fashion, spend money to buy back a bunch of "fancy" features. Tip 3: view three important performance indicators Refrigeration: is an important basis for consumers to buy air-conditioning products, the cooling capacity is too small to achieve the intended cooling effect; refrigeration capacity is too large, will result in a waste of resources. National standards require that the measured value of the cooling capacity should be not less than 95% of the rated value. Energy efficiency ratio: refers to the air conditioner in the cooling operation, the cooling capacity and effective input power ratio. The size of the value reflects the energy-saving air conditioner products. The larger the value of the energy efficiency ratio, indicating that the need to consume less electric power, power consumption is relatively less. Noise: air-conditioning operation of the noise generated by the noise is too large, it will seriously affect the lives of consumers. Tip 4: Check the certification mark Currently air-conditioning products have a mandatory certification mark has two: one is the "3c mark", issued by the Certification and Accreditation Administration of the State; the second is the "energy-efficiency mark", which contains the energy-efficiency ratio *** divided into five levels, the highest for the first level, five lowest. A level, five lowest. Selection of air conditioning, consumers should focus on checking these two signs, do not be dominated by other certifications. Tip 5: according to the norms for the installation of air-conditioning installation of the corresponding technical specifications, consumers must not pursue environmental beautification, random choice of installation location or replacement of random accessories. Before installation, you should check your own power supply, voltage, leakage protector to meet the requirements, as far as possible to avoid the leakage of flammable gases, open man-made strong electricity, magnetic field direct action of the place. After installation, it should be carefully checked. Finally, in accordance with the requirements of the instruction manual for trial operation. Tip 6: Correctly adjust the set temperature of the air conditioner Usually in the state of rest, sleep and other less activity, the room temperature of about 25 ℃, the human body feels comfortable. Setting the temperature too low, in addition to making people feel cold, will easily lead to frequent compressor start and stop, shortening the service life of the air conditioner. Tip 7: Regular cleaning and inspection of the air conditioner Regularly remove the filter of the indoor unit for cleaning can effectively improve the dust removal effect of the air conditioner, improve the ambient air quality. Regular cleaning of the heat sink of the outdoor unit can effectively improve its heat transfer coefficient and heat transfer efficiency, and improve the efficiency of the air conditioner. Regularly allow professionals to check the air conditioner, timely replacement of aging components, replenishment of refrigerant, can prevent the aging of the components of the machine and the human body harm, and can keep the air conditioner in good working condition. Tip 8: National three packages to protect the legitimate rights and interests of consumers Air conditioners belong to the three packages of commodities specified by the state, three packages of the machine is valid for one year, the main components (including: compressor, fan motor, thermostat) three packages are valid for three years. Air conditioning unit from the date of purchase within 7 days of performance failure, consumers can request a full refund or replacement. 15 days of performance failure, consumers can request depreciation return or repair. Three packages within the period of air conditioning after two repairs still can not be used normally, consumers can ask for a return or replacement with the maintenance records. Buying air conditioning precautions First of all, according to the size of the room, direction, floor height, the number of people living in the decision, in the sunrise, poorly ventilated rooms should be appropriate to increase the power of the machine. Generally speaking: 1 HP air conditioner for 12 square meters of space 1.5 HP air conditioner for 18 square meters of space 2 HP air conditioner for 28 square meters of space 2.5 HP air conditioner for 40 square meters of space 3 HP air conditioner for 50 square meters of space 5 HP air conditioner for 70 square meters of space A, how to determine the size of the cooling capacity of the air-conditioner are concerned about the purchase of many people are very concerned about the size of the cooling capacity of the air-conditioner. How to choose the size of the air conditioner cooling capacity, and the 1 pi, 1.5 pi, large 1 pi, large 1.5 pi and other names such as falling in the clouds, do not know how to decide. In fact, the concept of horse to describe the size of the air conditioner output cooling capacity is very vague, "horse" originally refers to the output power of the compressor motor. 1 horse air conditioner compressor motor output power of 735 w. In terms of the current market, the 1 horse machine in fact has referred to the output of the air conditioner for the 2500 w or so, 1.5 horse machine refers to the output of 3500 w or so, 1.5 hp machine refers to the output of the air conditioner for the 2500 w or so. In the current market, 1 HP is actually an air conditioner with a cooling output of about 2500W, 1.5 HP is an air conditioner with a cooling output of about 3500W, and 2 HP is an air conditioner with a cooling output of about 5000W. Note that 2500w, 3500w, and 5000w do not refer to the power output of the air conditioner, but to the cooling capacity. How much cooling capacity per square meter should be chosen for a specific room? Many people want to know an accurate formula. In fact, there is no such a recognized, acceptable, simple formula and calculation method. Even if there is a formula, because of its correction parameters are too many, the user's own calculation is not convenient. Moreover, the use of the room conditions are not static, and affect the cooling (heating) effect of too many factors. Can meet the cooling requirements, in the winter may be too much for the heating is not enough. Therefore, at present, it is generally based on experience. Consideration of the more thorough, sound recommendations for: 1 HP for about 14 square meters of the room; 1.5 HP for about 18 square meters of the room; 2 HP for about 30 square meters of the room. Second, to determine how to consider the brand as well as the brand on the market, after nearly a few years of competition, the survival of the fittest, the poor out. Where so far still occupy a certain share of the market, basically have their reasons for survival and conditions. As far as technology is concerned, it is difficult to distinguish between the imported and the joint-venture brands. Who is better than who must be, that is more of a commercial propaganda. As far as I know, many brands have experienced the ups and downs of the test, who all recognize the severity of the market and the risk. Therefore, who have been clear about the importance of advanced technology, the need for service, the advantages of low prices, the urgency of renovation. Therefore, consumers do not have to spend a lot of effort to identify which one must be better than the other, and should not follow the feeling to follow the promotional advertising, but should be based on their own needs to determine what kind of air conditioning to buy. Of course, this is not to say that the brand is not important, on the contrary, I strongly recommend that you buy domestic brand-name products, after so many years of fierce competition in the market, domestic refrigerators and air conditioners in the quality and performance of the imported brand name can fully compete, and, in the after-sales service than imported products. Third, buy window, cabinet or hanging machine different types of air conditioning have their own different characteristics, can not simply say which is good, which is not good. According to their own living room, economic ability and objective needs to determine. Generally speaking, the window unit is cheap, easy to install and use, but noisy. Hanging machine is not restricted by the installation location, easier to match with the interior decoration, looks beautiful, less noise, the price is a little more expensive, installation is also more troublesome, generally can only be on a room cooling. Cabinet power, strong wind, suitable for large rooms, and can be more than one room temperature regulation. But the price compared to the split wall-mounted air conditioning is a little more expensive, occupying an indoor area. Third, the air conditioner cold and warm, single cold should be selected according to the needs of the air conditioner has a single cold and cold and warm points, as the family actually how to choose and decide? Generally speaking, the southern region is not cold in winter, without heating, the choice of single-cooled air conditioner can be. In the north, many homes have centralized heating measures in winter, most of the time the heating function of the air conditioner is idle. But it is because of centralized heating, most of the cities in March 15 or so are cut across the board to stop heating, if the climate is not warm, or a cold wave, the air conditioning heating function is essential. At this time, the heating and cooling air conditioner can play a role, so the specific choice, should be considered for their respective regions and family circumstances as appropriate. Fourth, the heat pump type air conditioning heating capacity is poor and its countermeasures Heat pump type that is currently more purchase and use of ordinary heating and cooling air conditioners. China's southern regions due to the lack of centralized heating facilities, heating in the northern region and sometimes disregard the actual weather of the cold and warm, limited time frame across the board to provide and cut off the warmth, making it difficult to resist the cold weather torment consumers have to activate the heating function of the cooling and heating air conditioners. However, to the disappointment of many consumers, do not use do not know, a use shock. Heat pump air conditioner heating effect is so poor, so that they y lamented: I want to say I love you is not easy. In fact, this is the ability of the air conditioner itself. 1, the more to its heat the more is not hot The real energy attenuation is too fast Consumers will run the air conditioner heating enabled, always feel that the room with the air conditioner is not hot, the indoor machine air vents blowing out the wind is not hot. Better performance of the machine air temperature at 40 ℃ ~ 45 ℃; poor can only be 30 ℃ ~ 35 ℃. A 1.5 horsepower heating and cooling air conditioner will be 15 square meters of room heating to 16 ℃ ~ 17 ℃ is quite good. The key problem is that the heat pump air conditioner's heating output will decline with the decline in outside air temperature, and the magnitude of this decline is relatively large. Obviously, this heating output capacity, the room temperature is not up, the heating effect is also undoubtedly not good. 2, the room is a little hot and then cold because of the frost setting is wrong Heat pump air conditioner heating operation process of frost can not be avoided, as each frost will make the indoor machine to stop heating, therefore, the length of the frost time and the degree of frequent frost will have a direct impact on the air-conditioning temperature in the room high and low. Many consumers reported that the temperature in the room with the air-conditioner was high and low, giving people the feeling of being hot for a while and cold for a while. 3, the consumer's response Consumers in the purchase of air conditioners must be clear before, heat pump heating and cooling air conditioner heating function of your daily life is very necessary and essential. As the working temperature of the heat pump air conditioner in -5 ° C - 42 ° C between, if you live in the region of winter outdoor temperature below -5 ° C, heat pump heating and air conditioning will strike, so in the current heat pump air conditioner no major technological breakthroughs, should be careful to choose the ordinary heat pump air conditioner. May wish to choose inverter air conditioners, or with electric auxiliary heating type air conditioners, and other auxiliary heating appliances as your home winter heating means. This must be noted, the station master of the air conditioning heating is not good, is because of just simple electric heating type air conditioner. Fifth, the correct view of the health of air conditioners Stay in the air conditioning room, although comfortable, if not diligent ventilation will lead to heavy odor, poor air freshness and other uncomfortable feeling. The temperature difference between indoor and outdoor temperature is too large will also make people catch a cold. All these reflect the improper use of air conditioners will indeed lead to disease, but with a healthy air conditioner can rest easy? Not necessarily! To improve air quality for the purpose of designing a healthy air conditioner, no matter what form of air filtration device or negative ion generating device mounted on the ordinary air conditioner, only reflects the manufacturers of a desire only. Therefore, first of all, some form of air filtration device can adsorb how much harmful substances in the air, no health air conditioner to come up with scientifically recognized conclusions. Even if part of the role, but also have to tell the expiration date, can not "always healthy" it. Such as the frequent replacement of filter material will be the use of cost enhancement would be better to simply add an air purifier. Regular replacement of air filtration devices, whether consumers can self-complete more to be considered. Secondly, negative ions beneficial to human health is not disputed, but there is an effective concentration of the concept (health care and treatment of the concentration of the difference itself) and effective distance requirements (the release of the mouth away from the human breathing distance, the weaker the effect), which does not see which manufacturers can put the words clear. Drugs do not reach the dosage in vain, no matter how much concentration, randomly release a little negative ions and can not give people health. As for the photocatalyst, its effect is commercially advertised so magical? How much energy it absorbs and decomposes harmful substances? A little longer, once the dust on the catalyst media, photosynthesis will be lost, so that consumers how to solve the problem themselves? The industry's opinion is that the health of the air conditioner is not possible to create health, but science, the correct use of air conditioners, but still reliable and effective means of ensuring health: 1 moderate use of air conditioning; 2 moderate indoor and outdoor temperature difference; 3 timely window ventilation; 4 appropriate outdoor activities. Otherwise, not only can we not get health, but it will even harm our health. Issues related to health, consumers can not stay half sober and half drunk. Six, the air conditioner indoor unit can not be too small Household split air conditioner indoor unit has become a member of the bedroom, so the requirements of its decorative (appearance and shape) is also a little more fussy. In order to cater to the tastes of air-conditioner consumers, some manufacturers of split air-conditioners use their brains to change the shape of the indoor unit, and try to reduce the volume to create a different visual effect. A single emphasis on small, quantitative change finally caused a qualitative change. As the indoor unit air ducts are narrower, the circulation of air volume is small, resulting in slow heating, hot air can only be a small circulation in a certain area, the room temperature uniformity deteriorated, the heating effect is not good. Even if the air conditioner is running, a room will produce a more pronounced two temperature areas, standing in the indoor air vents below the head was blown hot, leaving a little distance but feel the need to add clothes. At the same time, *** vibration derived from the noise and large, especially the kind of inverter air conditioner indoor machine, when the compressor operating frequency changes to a higher frequency, by the outdoor machine through the piping to the indoor machine noise, due to the indoor machine between the internal parts of the space itself is limited, and even the implementation of the means of adjustment can not be used. Seven, be careful to choose not drain the window air conditioner? Window air conditioner in the cooling process on the evaporator will have condensation condensation precipitation and dripping out of the machine, if not properly installed hose and introduced into the sewer and let the water dripping arbitrarily, sprinkle, indeed, will incur the left and right neighbors and passers-by accusations. Some air conditioner manufacturers in order to help air conditioner consumers to solve this problem, the window air conditioner evaporator condensate concentrated in the bottom of the casing of the water tank, and then through the condenser fan blades on the dumping of water blades will be water tank condensate and splash to the condenser on the condenser, the use of the condenser's heat evaporates the condensate, which also improves the condensing conditions. This method is good from the desire to see the theoretical inference is also feasible, but one to the actual use of the line has become ineffective, and even the opposite. The problem lies in our poor environmental air quality, too much dust, which is the national conditions. Will be mixed with dust, sand condensate splash to the condenser, when the water evaporates, left on the condenser only dust and sand dirt. Over time, the condenser cover a "coat" and affect the condensation effect, which is only one aspect of the problem. The other side of the problem is that the accumulation of dust and silt on the condenser and other dirt is not "pure" and "good" people. They contain traces of acid and alkali substances will accelerate the condenser on the aluminum fin corrosion, thus further affecting the condensation effect and damage to the condenser, shortening the service life cycle of the air conditioner. Then again, some do not discharge condensate window air conditioner in the cooling process, sometimes accompanied by the production of disturbing dumping, splashing sound. Especially in the dead of night, this sound and the compressor running sound, air circulation sound intertwined with a song played in the middle of the night trio. Myth 1: to buy a new machine to buy Promotional Quotes: Since it is a new purchase of air conditioning, simply should buy a new model, a penny a penny well, the more expensive is definitely better to use. Air conditioning technology innovation, although endless, in fact, for air conditioning is only peripheral technology, the basic technology is very stable, is to achieve the most basic and ultimate function - cooling, and the majority of consumers on the demand for air conditioning is also so. The performance of the air conditioner will be extended with the use of time and reduce, so buy air conditioning is really not necessary to buy clothes like catching up with the popularity. Consumer Alert:Generally speaking, during the New Year's Day each year, manufacturers launch new air conditioning products began to market, this is the most expensive time of the year air conditioning sales. However, in May and June of the peak season, manufacturers of inventory merchandise sold in large quantities, consumers will be able to find cost-effective air conditioning at this time. Myth 2: low energy efficiency than next year on the out Promotional Quotes: see the air conditioning unit on the "energy efficiency ratio" logo, right, to next year, now the second level of energy efficiency has become the lowest index, on the out. Air conditioning does have "energy efficiency ratio", which is an important concept to measure its quality. According to the national energy efficiency standards, air conditioning energy efficiency score for 5 levels, 1 level for 3.4, the highest energy efficiency; 5 level for 2.6, the lowest energy efficiency. With the intensification of market competition and the country's emphasis on the development of energy-saving products, air conditioning, "access to the minimum energy efficiency ratio" will indeed gradually rise, but this depends on a variety of factors such as the market and consumers, "next year on the elimination of" is not realistic. In addition, consumers need to be clear that the "energy efficiency ratio" is only an initial value, the real meaning of energy saving should focus on "long-term energy saving". According to reports, the current air-conditioning companies to improve energy efficiency than the approach is mostly "small horse-drawn cart" type of design, will shorten the life of the compressor, so consumers should also be considered when choosing. Consumer alert: not the higher the energy-efficiency ratio of the product the more money, which involves the cost of the product and save money between the measurement of electricity. Comprehensive consideration of inputs, benefits, and sometimes choose the 2nd and 3rd energy efficiency ratio of the air conditioner will be more cost-effective. Myth 3: All frequency can save electricity Promotional Quotes: Now buy air conditioning is best to buy inverter, this power saving, more money is worth. "Inverter air conditioning" can indeed save electricity, but consumers must be clear when buying "DC inverter" or "AC inverter". DC inverter compressor efficiency than the AC inverter compressor 10% to 30% higher, the noise can be reduced by 5 to 10 decibels, compared to the real power saving. Consumer alert: DC inverter air conditioning prices are relatively much higher, and compared to fixed-frequency air conditioning, AC inverter air conditioning still do "cooling and heating fast, constant temperature" characteristics, so consumers can choose according to their needs. Myth four: big stores to buy the cheapest promotional quotes: buy air conditioning of course to come to the chain of big stores, we are here to ensure that the city's lowest price. At present, home appliance chain stores in becoming a strong sales channel for home appliances, while often claiming that their goods "cheapest". Price is the biggest killer app of the business, but also the ultimate reflection of its profits, and therefore often be moved enough to the most brains, ever-changing, elusive. And anxious consumers are often not possible to "comparison shopping", you can go online to the price of each brand of air conditioning models, so it is not easy to let the business drilled the price of the hole. Consumer alert: In fact, the large chain of home appliance stores have increasingly turned to reputation and service to win, due to rising operating costs, it is not possible to make a lot of price space to consumers. And many air conditioning store on the street is actually a good choice, these small stores are mostly a brand franchise, its cost is lower, the bargaining space for consumers is also greater, savvy consumers may wish to try. Site experience is indispensable many manufacturers in the purchase of the site have a prototype demonstration, which allows you to observe the prototype, reconfirm the quality of the product. For businesses that do not provide on-site demonstration, consumers should boldly put forward the requirements of on-site experience. 1, observe whether the shell is intact, clean. 2, the evaporator condenser is neatly arranged, there is no loosening, there is no inverted piece phenomenon. 3, buy a tow two air conditioning must confirm that there are several compressors, a tow two should only have a compressor, such as three compressors, power consumption and voice will be much larger. 4, start the machine should pay attention to the indoor and outdoor machine is running normally, there is no abnormal noise or friction voice. 5, convert the running state, test again. 6, touch the body with your hand, feel whether there is anomaly. 7, the purchase of imported products to recognize the origin, manufacturer and a variety of import procedures. 8, to recognize the product tares, trademarks, factory name and address. User rights and interests should be clear, after-sales service should be perfect according to
