Experimental Study and Simulation Analysis of Multifunctional Air Source Heat Pump Device

摘要

This paper presents the experimental and simulation study of a multifunctional air source heat pump device, which combined residence air conditioner with a heat pump water heater. Experiments on a laboratory made prototype unit indicates that the system ran well in different working mode with reasonable EERW from 3. 2 to 1. 4 with temperature of supplied water from 40°C to 60°C to; a variation of EERW from 3. 0 to 1. 5 when heating 60 Liter water in water tank from 9°C to 53°C. Model simulation is carried out as well in different working conditions and results basically agree with the experiment. To enhance the overall performance of this system further improvements on water cooled condenser and the system are proposed according to simulation results.
