GREENHOUSE FOR AIR CONDITIONING UNIT INSTALLATION HEAT-PUMP SYSTEM

摘要

The present invention relates to a heat pump system with an air conditioner for a greenhouse having a reheating function. Air supplied to a greenhouse is reheated by using waste heat (surplus heat) of a heat pump device in hot weather for heating and cooling the cultivation green house. The growth environment of crops is improved by controlling the temperature and the humidity for the crops. The amount and quality of products are increased. The energy can be saved by using the waste heat generated in the operation of the heat pump device without using separate fuel such as an existing boiler. Cooling water to be used for cooling is stored in a heat storage tank by the cooling operation of the heat pump device when the air temperature at the greenhouse is excessively reduced. A user efficiently handles intermittently generated heating load in hot weather by circulating hot water in a reheating heat exchanger with the generated heat and heating the greenhouse by operating an air conditioner. The user efficiently and quickly conducts the cooling operation by operating the heating operation of the heat pump device even in intermittently generated cooling load in winter, storing heat at a load side, and cooling the air by circulating the cooling air of a heat source around the reheating heat exchanger and operating the air conditioner.
