This study was conducted to develop a heat pump system to utilize waste heat within the greenhouse during the daytime in winter season. The system runs at 8 am to 6 pm for the heat storage operation, and from 6 pm to 8 am of the next day for the heat radiant work. In the case of the heat storage operation, the average solar radiation was with outside temperature. The of the system shows 4.59 in this operation mode. When the temperature goes up to , the system reached at 5.10. On the other hand, the of the system in heat radiation mode shows 2.63. In this case, the inside of the greenhouse temperature was reaches at when the outside temperature was .
