Study on energy consumption of air-source water-loop hybrid heat pump air conditioning systems

Presents the modes of different auxiliary heat sources of water-loop heat pump air conditioning systems. Proposes an air-source water-loop hybrid heat pump air conditioning system, which uses air and electric power as auxiliary heat source. Explores its energy consumption in different cold and heat load ratio between inner and peripheral zones under different ambient temperatures. Analyses the effect of circulating water temperature on energy consumption of the system. Compares the primary energy consumption between the system and conventional water-loop heat pump air conditioning system with electric boiler or coal-fired boiler as auxiliary heat source.
