• This paper presents the individual experiment result of heat pump system with air source only and water heat source only. The controllable data which are the compressor room temperature for air source and the water inlet temperature to water evaporator for water heat source are varied from 15, 20, 30℃ and 20, 30, 40℃, respectively. With the air source only, the maximum COP can be achieved 4.3 when the inlet circulation water to solar collector was 15℃ and inlet circulation water from temperature control chamber was 20℃. With the water source only, the maximum COP can be achieved 4.72 when the inlet circulation water to solar collector was 25℃ and inlet circulation water from temperature control chamber was 20℃. The inlet water temperature setting to water evaporator (PV/T) and inlet water temperature to water condenser are significant influence to the COP performance. The ambient air temperature and solar radiation must be monitored intensively for automatic dual heat source applied.
