<；P>；PROBLEM TO BE SOLVED: To provide an air-conditioning system for greenhouse, enabling air conditioning stably and independently of weather, and also capable of reducing power consumption. <；P>；SOLUTION: The air-conditioning system includes: a greenhouse 10； an outside air conditioning chamber 20； a solar heat collector 30； and an adsorption-type refrigerating machine 40. An outside air conditioning area 202 and a reclaiming area 204 are collocated in the outside air conditioning chamber 20； in the outside air conditioning area 202, the introduced outside air (a) is cooled by the evaporator 214 of a heat pump apparatus 212 to raise relative humidity followed by dehumidification by a dehumidifying rotor 218. The outside air (a) heated by the heat of adsorption of the dehumidifying rotor 218 is cooled by a heat exchanger 222 and subjected to temperature adjustment by a humidifier 224, thus supplying the resultant outside air into the greenhouse 10. In the reclaiming area 204, the outside air (a) introduced is heated by the condenser 232 of the heat pump apparatus 212, and by the thus heated outside air (a), the dehumidifying rotor 218 is reclaimed. The hot heat source for the heat exchanger 222 is fed from the solar heat collector 30, while the cold heat source is fed from the adsorption-type refrigerating machine 40. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
