The present invention relates to a heat pump system capable of cooling, heating, and dehumidifying a greenhouse. More specifically, a heat source for cooling and heating generated in a heat pump device and an underground heat source generated in an underground heat exchanger are transmitted to an FCU installed in the greenhouse; the FCU provides cools, heats, and dehumidifies the greenhouse; likewise, the heat pump system uses the heat source of the underground heat exchanger instead of an additional heat source such as boiler; and thus the heat pump can save energy. The heat pump system improves a crop growth environment by adjusting the temperature and humidity to be preferred by crops as the heat sources for cooling and heating generated in the heat pump device are mixed with each other. Accordingly, the heat pump system can increase the amount and the quality of crop production. A thermal storage tank is manufactured in the shape of a high tower to be higher than the greenhouse; and pipes connected to a lower portion of the thermal storage tank are connected to each circuit so that pressure of the whole system can be the same. Moreover, construction costs of the heat pump system can be reduced because a pressure adjusting expansion tank, which have been used for the prior system, can be removed. |
