In the existing buildings, hotel type buildings are also large energy consumption households. On one hand, the refrigerating/heating and domestic hot water system of the air conditioning system needs to run all the year round and consume a large amount of electric energy; on the other hand, the hotel building power distribution room and the laundry room can generate a large amount of heat in the running process of equipment, and in order to ensure the normal running of the equipment in the equipment rooms and the proper working temperature of personnel, the refrigerating system also needs to provide considerable air-conditioning refrigerating capacity for cooling the equipment, so that the energy consumption of the hotel electromechanical system is further increased.
Summarizing the above, it can be seen that the hotel hot water system needs "heat" to heat cold water, and the air conditioner refrigeration needs to cool the places generating "heat" such as the power distribution room, laundry, etc., and needs to provide "cold". The hot water system needs to consume electric energy for heating, and the equipment room cooling system needs to consume electric quantity for refrigerating.
