室用冷暖房装置の改良に関する。Detailed Description of the Invention The present invention relates to a heat pump equipped with a condenser that condenses refrigerant from a compressor through heat exchange with a heat transport medium, and an evaporator that evaporates the condensed refrigerant through heat exchange with a heat transport medium. , a greenhouse air-conditioning system that is provided with a flow path that can selectively supply the heat transport medium cooled by the evaporator of the heat pump and the heat transport medium heated by the condenser to a heat exchanger provided in the greenhouse. Regarding improvements.

出る。When growing crops in a greenhouse, water evaporates from the leaves of the crops and evaporates from the ground during the day, so even if the windows are closed, the absolute humidity remains to a certain degree, and when the room temperature drops at night, the relative humidity decreases. The mountain rises and the growth of crops is adversely affected.

て温室の保温を行っている。Therefore, during the daytime, using the air-conditioning device, the heat transport medium cooled by the evaporator of the heat pump is put into a cooling operation mode to supply the heat exchanger in the greenhouse, and residual humidity is carried out.
At night, the greenhouse is kept warm by entering a heating mode in which the heat transport medium heated by the heat pump's condenser is supplied to the heat exchanger inside the greenhouse.

に設けである点にある。In this case, conventionally, well water was used for heat exchange in the heat pump's condenser during daytime cooling and dehumidification operation, and the well water heated by the heat exchange was wasted as is. In addition, during nighttime heating operation, well water is also used as a heat source for the heat pump's evaporator, and the heat from the relatively low-temperature well water is absorbed by the heat pump in the greenhouse air-conditioning system with the above configuration. Channel 1 for selectively forced circulation of a heat transport medium between the condenser and the heat storage tank and above the evaporator and the heat storage tank
There are certain points in place.

効率を高めることができるようになった。According to the above configuration, by switching to a mode in which the heat transport medium flows between the condenser and the heat storage tank during daytime dehumidification operation, the heat used for condensing the refrigerant is recovered to the heat storage tank.
During nighttime heating, by switching to a state where the heat transport medium flows between the evaporator and the heat storage tank, the heat stored in the heat storage tank during the day can be used as a heat source for the evaporator, and the heat can be used to condense the refrigerant during the day. Heat can now be used effectively for heating at night, increasing heating efficiency.
