Research on commissioning method of air conditioning systems in public buildings (2): Secondary water pump system with multistage plate heat exchanger

Through commissioning of secondary water pump system with multistage plate heat exchanger in a super high-rise public building in hot summer and warm winter zone in China, summarizes the key links and effective adjustment methods in the actual operation of the secondary water pump system with multistage plate heat exchanger, starting from the actual terminals cooling demand, reducing the energy consumption of the cooling water system while avoiding excessive cooling by setting reasonable automatic control parameters and accurately matching the water temperature and water demand of terminals, so as to realize the energy saving operation of the air conditioning system.
