The invention discloses an air source heat pump machine room pump-replacing-valve grouped group-control system. The system comprises a plurality of sets of air energy heat pump units, and each air energy heat pump unit comprises a plurality of air energy heat pump modules, a plurality of fixed-frequency water pumps, a plurality of electric adjustment valves, a variable-frequency water pump and a water segregator. Hot water outlets of the air energy heat pump modules are all connected with the input ends of the corresponding fixed-frequency water pumps, the output ends of the fixed-frequency water pumps are all connected with the input ends of the corresponding electric adjustment valves, the output ends of the electric adjustment valves are all connected with the input ends of the variable-frequency water pumps, the output ends of the variable-frequency water pumps are all connected with the input ends of the water segregators, and output water separation openings of the water segregators are all connected with the corresponding air conditioner tail ends. Compared with the prior art, the problem of difficulty in defrosting regulation and the problem of start-stop control of a single air heat pump module are solved, variable-frequency conveying is performed when the water demand is low, and energy conservation of the system is achieved.
Description
【Technical field】 [0001] The patent of the present invention relates to an air source heat pump room with pumps instead of valves grouping group control system. 【Background technique】 [0002] Air source heat pump is a kind of heating equipment that uses a small amount of electric energy to drive the compressor to work, and uses the circulation of refrigerant to produce heat from the air. It is safe and reliable in operation, environmentally friendly and energy-saving, and has high economic applicability. in a broad way. Air source heat pumps for coal-to-electricity conversion are generally controlled by machine room clusters, and multiple modular units operate to provide hot water for the air-conditioning terminal. [0003] When the air source heat pump cluster is controlled, the air source heat pumps operate in parallel, causing the modules that are not turned on to continue to "bypass" the return water back to the water supply, reducing the supply water temperature and S...
