Air in the greenhouse is led to the condenser with a condenser fan 8, heat-exchanged to become hot air, and blown out from a hot air duct 6 to outside the case frame. Furthermore, air in the greenhouse is led to the vaporizer 5 with a vaporizer fan, heat-exchanged, dehumidified, cooled, and blown out from a cold air duct 7 to outside the case frame. The ducts 6 and 7 are each made expandable and contractable, and changeable in direction so as to lead cold air dehumidified and cooled with the vaporizer and hot air heated with the condenser to a desired direction in the greenhouse. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
