For hotels, the time-of-use electricity price policy can be used to greatly save operating expenses. Ice storage air conditioning system uses little or no electricity when the electricity price is high, and releases the stored cold energy for use, while it uses more electricity when the electricity price is low, and stores the generated cold energy. As the peak-to-valley ratio of electricity price in Hangzhou reaches 2: 1, the annual saving of operating electricity fee is considerable. In addition, at the peak of air-conditioning load, it is necessary to rely on ice melting for refrigeration operation, so the installed refrigeration capacity of air-conditioning host can be reduced, the installed capacity and investment of corresponding cooling towers, circulating pumps and other equipment will also be reduced, and the initial investment cost of electricity can also be reduced. Therefore, the application of ice storage air conditioning can be described as a double harvest of economic and social benefits.
Due to the maturity of ice storage technology, low temperature air supply is possible. Low temperature air supply can reduce the humidity of indoor air and make people feel fresh. On the premise of satisfying human comfort, the indoor air temperature can be appropriately increased, so that when guests leave the air-conditioned room, they can quickly adapt to the change of outdoor temperature without feeling too uncomfortable and prevent air-conditioning diseases. At the same time, low-temperature air supply can prevent the growth of bacteria, which is beneficial to the health of hotel guests.
In Yun Qi Hua Ting Resort Hotel, their reclaimed water treatment system caught our attention.
The so-called reclaimed water reuse refers to the advanced treatment of wastewater after it is treated by sewage treatment system, such as coagulation, sedimentation, filtration, biochemical degradation, sterilization and disinfection, etc., to meet the requirements of reuse. Reclaimed water is between "supplied water" and "supplied water". Although inedible, it fully meets the requirements of greening and other aspects. The hotel uses a lot of water, and produces about 600 tons of waste water every day. After treatment, it can be reused for greening irrigation, landscape fountains, toilet flushing, car washing and so on.
At present, there are many domestic sewage treatment processes, and Yun Qi Hua Ting Resort Hotel adopts hydrolysis-aerobic process. The characteristics of this process are as follows: firstly, the hydrolysis tank replaces the traditional primary sedimentation tank, and more importantly, after hydrolysis, the organic matter in the sewage not only changes in quantity, but also changes in physical and chemical properties, which makes the sewage more suitable for subsequent aerobic treatment and can be purified with less gas in a shorter residence time. Secondly, the process completes the treatment of sludge while treating sewage, which unifies the treatment of sewage and sludge and can cancel the digester from the traditional process. In this way, not only the process is reliable, but also the emission index is stable, the investment and operation cost are low, and various human factors can be known. Thirdly, the volume and aeration amount of the aeration tank are obviously reduced.
After the hotel adopts this system, it not only saves considerable water and sewage charges every year, but also brings immeasurable social benefits.
Ningbo Xinzhou Hotel
New management system of energy saving and consumption reduction
Ningbo Xinzhou Hotel pays more and more attention to energy conservation. From the perspective of sustainable development, it closely combines the importance of energy conservation and consumption reduction with the importance of maintaining the competitive advantage of enterprises, and establishes and improves the energy conservation and consumption reduction management system of "management supervision and everyone's participation". The engineering department is directly involved in energy management, making energy-saving plans and arranging daily inspections. , and take "diligent inspection, grasping implementation and eliminating hidden dangers" as the working purpose, and implement them one by one. Employees in each shift are required to realize that energy saving is not at the expense of service quality, and should not reduce customer service quality or affect service standards. In recent years, the basic energy consumption of hotels has not increased because of aging equipment and declining performance, but has decreased year by year.
Hotel energy saving is a routine work with great potential. Energy saving is mainly achieved by strengthening management. Energy saving shall not affect the quality of customer service or reduce customer comfort. Therefore, the managers and supervisors of the engineering department often deeply analyze the energy consumption of each region, find out the weak links, formulate practical work measures, compare the consumption of electricity, oil and steam (liquefied gas, steam and refrigerant) in each stage and region through testing, conduct patrol inspections regardless of time period, observe the operation of air conditioners in each region, observe the lighting situation of light sources, and see if there is oil, water and steam "running, dripping, leaking and leaking". Through careful analysis and calculation, the Engineering Department found that the full-load running time of the central air conditioner is less than 1/2, and even in the season with the largest air conditioning load in summer, the load in the latter half of the night and the early morning is relatively small. The frequency conversion system of central air-conditioning refrigerant pump is mainly reformed, which saves electricity obviously and has stable refrigeration. At the same time, it is emphasized that the temperature of the lobby area of the air-conditioning machine room should be detected regularly: firstly, it is necessary to ensure the operation, and ensure that the ambient temperature of the public area reaches the four-star requirement by turning on the machine; Then, efforts should be made in the operation: control and adjust the corresponding effluent temperature according to the weather conditions and environmental temperature changes every day, and strengthen the monitoring of environmental temperature. Fresh air is used in the breakfast area, because the outdoor temperature is suitable at this time, and the air in the restaurant can be kept fresh; Reasonably close the air conditioning refrigerant water valves in some unnecessary areas or adjust the valve size. In the backstage administrative area, the temperature in the staff area is suitable, so try not to turn on the air conditioner if it can be turned off. Strengthen the control of air conditioning in conference rooms. About half an hour before the meeting, the engineering department will turn on the control switch. The engineering department only provides ventilation for the banquet hall during the meal preparation, turns on the air conditioner 15 minutes before the banquet to ensure the requirements of the guests, stops using it after the meal, and overhauls the air conditioner, refrigerator, freezer and refrigerator thermostat in guest rooms and public areas. Maintain and clean air conditioning motor, insulation layer, blades, fins, pipes, return air filters, etc. Create a warm and comfortable environment for the guests. It is also stipulated that the consumption of water, electricity, gas and fuel oil should be recorded regularly every day to accumulate data, so as to find out abnormal consumption and find out the reasons.
The engineering department not only maintains the power distribution system, but also adjusts the capacitance compensation of the system at any time to make the power distribution system more reasonable. High-power mechanical and electrical equipment adopts frequency conversion device, and metering devices such as sub-meter and sub-meter are installed where separate assessment is needed. The outdoor landscape lights and decorative lighting systems of the main and auxiliary buildings are equipped with intelligent clock-controlled appliances. Actively carry out water-saving projects, focusing on the inspection of large water users such as catering kitchens, laundry rooms and staff quarters, and putting an end to the phenomenon of running water. Cooperate with the administrative office to publicize energy conservation, create a good atmosphere for everyone to save energy, and make sure that people turn off the lights, people turn off the water and stop the air conditioning. At the same time, the department pays attention to the daily energy consumption changes, finds out the reasons in time, eliminates the blind spot of energy saving and puts an end to hidden waste. Under the premise of not reducing lighting, the backstage administrative area and staff area should make full use of natural light to reduce lighting electricity consumption. Priority should be given to light sources and high-efficiency lamps with high light efficiency and good color rendering in key areas, and the lighting system in the employee area should be reformed. Inductive switches are used in the personnel passage of the main and auxiliary buildings. Adjust the tap water flow in the staff area to half of the normal situation to reduce unnecessary water loss. Replace and install steam and water saving valves in kitchen and laundry room. Do a good job in the operation and maintenance of all steam pipes, valves, pressure reducing valves, traps and other above-mentioned equipment in the boiler room. For domestic hot water, it should be adjusted with the change of outdoor temperature, and the hot water temperature should be selected reasonably to ensure the integrity of pipeline insulation layer. Check frequently, carefully check whether the equipment and facilities in each area are abnormal, listen to whether the equipment is abnormal, and often touch the temperature, vibration and smell of the equipment to ensure that the equipment problems can be found and solved in time without causing heavy losses, and strive to make the work of energy saving and consumption reduction more detailed and comprehensive.

F&B Department: Focus on cost saving, and hold a big discussion on "reasonable procurement and reducing inventory". Strengthen the communication between the front and back office, reasonably purchase goods according to the actual food demand and quality standards, and focus on selecting green food. Every team in the kitchen on the second floor will use fish bones, fish heads and fish tails as raw materials for soup. Prepare materials in strict accordance with the number of diners to prevent waste of raw materials. The dishes saved from the conference buffet are used as staff meals to avoid waste. The staff of the vegetable washing class strengthened water-saving management.
Finance Department: Ensure green procurement, strictly examine and approve the procurement system, and control operating expenses. Make a detailed account and provide accurate data comparison and analysis. The basic materials of the hotel's own decoration and contracted decoration are all environmental protection materials, and the material suppliers are required to provide environmental protection signs, including plywood, blockboard and paint.
Other departments: actively carry out various forms of "greening" activities training and education. Turn off the lights and water at will, try not to use air conditioning, implement paperless office, and advocate energy saving and consumption reduction anytime and anywhere.
Xiangyi Hotel Hangzhou
The rhyme of salvation is sweeter.
Since the opening of Hangzhou Xiangyi Hotel for seven years, the revenue efficiency has been rising, but the total energy consumption of electricity, oil and water has not increased much every year. In 2004, it saved 320,000 kwh of electricity, 0/09 ton of oil and 0/0.9 million kwh of water, saving more than 600,000 yuan in total.
First, introduce ISO 14000 environmental certification, connect with international standards, and upgrade enterprise energy-saving standards and norms.
As early as 0 1 April, Xiangyi, as a pilot unit in Hangzhou, took the initiative to introduce the international ISO 14000 environmental management quality system. At that time, the environmental protection policy established by Xiangyi was clearly put forward as: "Save energy and reuse, reduce pollution, add green and fragrance, and be full of spring." By establishing the overall goal and formulating specific measures to achieve the goal, the management responsibilities of each department are clarified, and a set of related documented management procedures and operating standards are formulated to effectively control the whole process of operation, so that various environmental factors can be effectively controlled and managed, and important posts can be operated according to documents, and relatively perfect preventive and emergency measures are established. During the operation of the system, check related activities, monitor major environmental impacts and equipment operation, supervise the completion of environmental performance and objectives, and establish relevant records for traceability. An internal review was conducted to understand the operation of the system, verify the applicability, adequacy and effectiveness of the system, and make timely revisions. On the basis of two internal audits, a management review meeting was held and a certificate was obtained through certification.
The certification results show that since the introduction of ISO 14000 management system, the hotel has saved nearly 240,000 yuan in water, electricity and raw materials consumption and nearly 60,000 yuan in low-value consumables consumption one year after passing the certification. At the same time, according to the requirements of environmental management, the noise reduction facilities of key parts that affect the environment, such as boiler room and air conditioning exhaust port in basement, were reformed four times, which met the satisfactory requirements of environmental monitoring. The hotel has complete sewage and waste gas treatment facilities, and the water pollutants and waste gas pollutants meet the national emission standards every year after being tested by the environmental protection department. The treatment facilities are complete and effective. The noise at the boundary of the plant conforms to the standard of environmental noise use area. At that time, Xiangyi, as the only hotel representative, made an experience introduction at the Hangzhou Environmental Management System Working Conference. The hotel not only achieved good environmental performance, reduced operating costs, but also greatly improved employees' environmental awareness and work quality, established a good social image and enhanced market competitiveness.
Second, create green hotels, advocate green consumption and green sustainable development, and improve the effectiveness of hotel energy conservation.
Since the end of 1999, Xiangyi has been actively participating in the green hotel certification activities initiated by Zhejiang Province. Xiangyi continues to deepen the green management concept and management, improve the green service measures, and establish the green brand image of Xiangyi Hotel. Implement the Notice of Zhejiang Provincial Tourism Bureau on Carrying out the Certification of Green Hotels in Zhejiang Province and the local standards of green hotels in Zhejiang Province (DB33/T326200 1), and constantly do a good job in energy-saving management, environmental protection, reducing material consumption, and providing green products and social, environmental and economic benefits. In 2003, it won the title of "Green Hotel" in Zhejiang Province with high scores, which effectively promoted the hotel's energy saving and consumption reduction. In terms of energy-saving management, the hotel has established a classified account of energy-consuming equipment and an account of energy-consuming metering instruments, and installed water, electricity and steam metering instruments where they can be managed in different areas. For the energy consumption of water, electricity and steam, there is a comparison, analysis and suggestion report between the hotel and various departments every month, and the management departments of catering, guest rooms and recreation have energy consumption quotas, assessment systems and reward and punishment methods. Reduce material consumption. The guest room reduces the consumption of disposable items. Reduce disposable packaging supplies. According to the large amount of office paper and daily copying in the hotel, the hotel has developed an office OA system on the one hand, and adopted a system form on the other hand, requiring documents to be copied on both sides and distributed to clerks in various departments for execution. By explaining the copy of customer service, it is suggested that guests use double-sided copy, which has played a positive role. For a large amount of detergent, on the one hand, the hotel establishes a good collection system, controls consumption by changing empty cans, and on the other hand, recycles toothpaste and soap. Measures are also taken to control the common spare parts of the office supplies engineering department to reduce consumption and save costs.
Three, science and technology energy saving, scientific saving, appropriate use of advanced technology and equipment to make a qualitative leap in energy saving.
Xiangyi actively explores new energy-saving modes. Energy saving and consumption reduction need to benefit from "running, running, dripping and leaking" to management, and use the latest technology to benefit from technology. Xiangyi not only establishes and improves the rules and regulations of environmental protection, energy saving and consumption reduction, but also strengthens energy saving management. The three blocks of hotel energy consumption have been completed: electricity, oil and water. The hotel has established various energy-consuming equipment accounts, installed water, electricity and steam metering sub-tables, analyzed the energy consumption quota and assessment system, and continuously reduced material consumption. At the same time, we also pay attention to the timely use of the latest science and technology, dare to invest, and do a good job in energy saving and consumption reduction from the source, so that energy saving and consumption reduction will be changed from putting an end to "running around" to using scientific and technological means, and technology will create benefits and achieve good results. In 2002, I used the electricity-saving money to pay for the goods, and bought and installed the inverter of the air-conditioning host. Four CGI intelligent frequency converters, such as chilled water pump, cooling water pump, air conditioning secondary water pump and air conditioning hot water pump, were purchased and installed. The central air conditioning system adopts energy-saving refrigeration unit, the water pump flow system adopts variable flow regulation technology, and the air cabinet adopts variable air volume regulation technology. Save electricity by 330,000 kwh and cost by 290,000 yuan. Two years later, the equipment investment fund was recovered from the power-saving fund. The hotel also invested more than 300,000 yuan to establish an office OA system, which not only improved the management level and work efficiency, but also saved 50,000 pieces of office paper every year. At the same time, the hotel also invested 60,000 yuan to install a 3 cubic meter hot water storage tank system, and invested 6,543.8+0.4 million yuan to build a boiler flue gas waste heat recovery system and a laundry steam flow monitoring system, which provided material guarantee for saving oil 100 tons in 2004 and effectively improved the work effect of energy saving and consumption reduction.
Fourth, innovate ideas, dare to be the first, and save energy requires us to actively integrate into the era of rapid progress and change and win the opportunities for development.
Xiangyi took the lead in setting up an online sales center in tobacco hotels in the province on 200 1. Without increasing the sales staff and sales expenses, we adopted the way of sharing with the website in advance. Online booking has been popular for many years, and it has not only been successfully managed in the forefront of hotels in the province, but also developed into the number one big customer in the hotel in 2004. Xiangyi combines the current situation of domestic network development, and makes full use of all kinds of travel booking websites to serve me for mutual benefit and common development. We have established a good cooperative relationship with more than a dozen large professional booking websites around the world, especially with Ctrip, Business Travel, Shanghai Holiday and other travel websites. In this way, Xiangyi has sold more than 25,000 rooms online during the four and a half years of online booking, and has created an income of nearly100000 yuan. Now Xiangyi Office OA, greeting card e-mail, and recently catering promotion information has also begun to send text messages in groups.
Service innovation also means a win-win situation of energy saving. Since last summer, the guests who entered Hangzhou Xiangyi Hotel have sharp eyes. The dark and heavy suits representing high-star symbols introduced by foreign-funded hotels are gone, replaced by bright short sleeves worn by waiters and even short sleeves worn by managers. "Let our feelings synchronize with those of the guests", so it has become everyone's conscious action to turn up the fragrant air conditioner by 1-2 degrees.
