Design of water pumps in heating and air conditioning systems

Analyses the operating conditions of water pumps in heating and air conditioning systems, discusses the importance and the method of reasonable selecting a circulating pump head. The water pump used in winter and summer should be selected and arranged separately based on the flow rate and resistance loss. Analyses the influence of parallel water pumps on the operating and condition conversion of the system, and presents the cavitation in a pump in heating and air conditioning water systems.
