Experimental Investigation and Numerical Simulation for High Temperature Air Source Heat Pump with New Mixed-Refrigerant

Abstract:

Studies on air source heat pump (ASHP) transfer to high temperature, the performance of air source heat pump greatly depends on the ambient temperature. Aimed at the prototype aeroplane of high temperature air source heat pump, New mixed-refrigerant M-R was adopted, and a simulation was made under a standard conditions with Aspen Plus software. And the results was validated by the experiments. The results showed that a well trend between theory and experiments. In addition, experimental investigation of high temperature air source heat pump were carried out at different conditions. The COP was 1.15, the discharge temperature of compressor was 108.6°Cwhen the outlet water temperature was 85.1°C. The heating capacity is superior. This achieved a leading level at home and abroad.
