| Abstract | Increase of heat pump utilization affected to higher energy consumption for all sections. In order to reduce energy consumption for heat pump, solar collector was selected to assist heating of water temperature due to solar radiation. This study focused on coefficient of performance (COPt) and energy consumption of small water to water heat pump operated with solar collector for residential application. Firstly, solar collector was tested and followed by ASHRAE 93-77 then 70.5 % of efficiency was obtained. Secondary, small heat pump operated by R410a as refrigerant was experimented with 300 liters of water and followed by EN255-3 then 1.53 of COPt and 7.02 kWh/D of average energy consumption were resulted. When small heat pump operated with solar collector to reach 50?C of hot water, 1.77 kWh/D or 25.2% of average energy consumption was lower compared to operation only small heat pump. This study was concluded that small heat pump assisted by solar collector was applicable for energy conservation in residential application. |
