Nice hotel energy-saving service program
First of all, the hotel's electric power status quo
Tertiary industry's rapid development, as a typical power service industry in the number of the rapid increase in the competition more and more hotels, hotels and most of the other business are facing a decline in profits. Hotel range of electrical equipment in order to provide a comfortable environment for guests, each room is not only light lights, TV, refrigerator, air conditioning, water heater, water heater and other electrical equipment, if it is all open, all the power more than 2,000 watts, which means that if a traveler is in the room, all the electrical appliances are open, by the amount of power required for an hour more than 2 degrees.
A common indicator in international hotels and other industries, the power allocated to each room for the day is 23 to 26 degrees. That is 1,000 customers of the hotel, daily consumption of about 23,000 to 26,000 more than the cost of industrial electricity is a major cost control costs, the cost of electricity has become a hotel is necessary, but also to reduce the operating costs of hotels, the most effective means to improve the competitiveness of the industry.
Hotel's analysis of electricity symptoms
(a), transmission and distribution system energy losses are serious
1, due to seasonal or tourist season, the use of the grid is not efficient
Hotel occupancy rate varies greatly when the load factor of the transformer is generally not high, and sometimes there is little or no load operation, resulting in high losses in the transformer itself, the rate of change of voltage is very high! Unnecessary waste.
Power supply line losses
As the hotel's electrical equipment power lines, long transmission distances, apparent power, multi-branching, concentrating a large number of losses and the impact of RTD line losses, resulting in lower terminal voltage to reduce the decline in the efficiency of energy use, and there is a certain security risks;
3, poor power quality, the number of large-scale electrical equipment and types of hotels, power Electronic devices, electrical appliances, the use of non-linear loads, resulting in severe load non-linearity, voltage waveform distortion, poor power quality, greatly reducing the efficiency of energy use, but also affect the service life of electrical equipment and the use of safety.
(B), the energy consumed by electrical equipment is not highly utilized
Room Mixed Load Line Electricity guest room electrical loads for lighting, television, water heaters and other water machines.
Most of the lighting equipment or old-fashioned incandescent lamps, energy consumption;
b, all single-phase power supply for electrical equipment, is a serious three-phase unbalanced line, resulting in excessive zero-sequence currents and increased energy losses.
C, the working voltage is generally higher than the rated value, not only is the voltage higher than the rated value, but also the energy loss increases. The voltage is generally higher than the rated value, not only can be more efficient lighting, water diversion, water heaters and other equipment, but will lead to equipment heat and premature failure, wasting energy and reducing the life of electrical equipment.
2, air-conditioning equipment electric (cabinet or central air conditioning) First, the hotel air conditioning system design choices, most of them are expected to maintain a margin of about 20%, but due to the impact of room occupancy,
seldom run completely at full capacity; Second, air-conditioning circulating water system is actually running at a fixed maximum design flow rate, does not change with the load. Can not reach the host, auxiliary equipment and comfortable temperature three reasonable dynamic automatic adjustment ends, resulting in low utilization of electrical energy, a serious waste of energy.
(C), the guests' awareness of energy saving, energy saving management simple
Hotel profit business, the face of the customer base, temporary accommodation for foreigners, the ubiquitous money, and should enjoy the use of no white without the consumer's mentality, coupled with the fate of the hotel rooms and timely monitoring of power consumption, is because there is a long bright lights during the day, out of the house and forget to turn off the lights, TVs and other electrical devices And other phenomena lead to a very serious waste of energy. At the same time, most of the hotels from the needs of guests, but from the support of equipment can be normal operation of electricity consumption management, rather than the use of efficiency, energy consumption standards and equipment life of the overall energy use from the point of view of lean management, energy utilization is low.
Hotel savings system
(a) Project design
