In order to avoid the rapid on and off, the condition of partial load is maintained by the heat storage device. With Plate heat exchanger in the air to water heat pump, the heat storage device is for heating along with large variation of supply, defrosting time and return water temperature. A Water tank and an inner double pipe heat exchanger were included in the heat storage device. The heat storage device can able to reduce on and off times by utilizing the compressor in energy storage, as it consists of appendages and electric heater. In electric heater and electric storage, there is a shortage of heating during defrosting. Under partial load, it reduces on and off times by utilizing the compressor in heat storage device by four times per hour rather than six times per hour. The reduction in on and off times were exposed by the plate heat exchanger performance test. Also, there is a reduction of defrosting time in heat storage device with electric heater unit by 78s and 84s. While it reduces to 30.73ºC in plate heat exchanger, many steady running parameters either inlet heating water temperature of heat storage device or heat storage device with electric heater is about 33ºC. Thus, the enhancement in the unit performance in designed heat storage device is obtained. With air to water heat pumps, it is suitable for new projects.
