Performance Study Of Air Source Heat Pump Space Heating And Cooling System With Small Temperature Difference Terminals

In order to solve the space heating problem in south China, this thesis comes up with an air source heat pump(ASHP) solution. By the use of small temperature difference indoor terminals, including small temperature difference fan coil units and floor heating coils, the energy consumption of ASHP can be reduce by 15% and 20% in summer and winter, respectively. Also, according to the test of this thesis, indoor temperature distribution uniformity can be increased as well. Moreover, we simulated the power consumption of ASHP by using simultaneous building load curve and ASHP power consumption curve. Finally, we proposed an optimized method for the fabrication of small temperature difference fan coils and air source heat pump family energy center.
