Abstract
Description
technical field
[0001] The invention relates to a central air-conditioning system, in particular to an energy-saving central air-conditioning system. Background technique
[0002] With the rapid development of social economy, hotels, office buildings, large venues and other places using central air-conditioning systems are becoming more and more widespread. Since the design of the central air-conditioning system is mostly calculated and selected based on peak climate conditions and load capacity. In the actual operation of the system, with the change of season, time and the heat dissipation of the used space, the actual load is far lower than the design value most of the time throughout the year. Take hotels as an example: air-conditioning load generally includes: ① building envelope heat transfer (including solar radiation heat); ② lighting, refrigerators, kettles and other electrical appliances heat dissipation; ③ human body heat dissipation; ④ fresh air load and power eq...
