<p><P>PROBLEM TO BE SOLVED: To improve the operation efficiency of a device that separately processes sensible-heat load and latent-heat load in air-conditioning, by utilizing adsorption and desorption using a desiccant. <P>SOLUTION: This refrigerating air-conditioning device includes a refrigerant circuit, constituting a refrigerating cycle including a compressor 4, a heating heat exchanger 5, a gas-liquid separator 6, an outdoor heat exchanger 7 acting as a condenser, an expansion valve 8 and an indoor heat exchanger 7 acting as an evaporator, an intake air duct 21 and an exhaust air duct 22 performing ventilation between the inside and outside of a room; a desiccant rotor 16 for adsorbing moisture from the intake air from the outside of the room, in the intake air trunk and desorbing the moisture to the exhaust air from the inside of room in the exhaust air trunk; and a cooling heat exchanger 12, disposed downstream with respect to the desiccant rotor of the intake air duct. The heating heat exchanger is disposed upstream, with respect to the desiccant rotor, of the exhaust air duct; the refrigerant circuit includes a bypass circuit 10, branched from the gas-liquid separator and connected to a suction side of the compressor; and a second expansion valve 11 and the cooling heat exchanger 12 are disposed in the bypass circuit. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
