Abstract (en)
[origin: WO02070958A1] A dehumidifying air-conditioning apparatus comprises a pressurizer (4) for raising a pressure of a refrigerant, a condenser (5) for condensing the refrigerant to heat a high-temperature heat source fluid, and an evaporator (1) for evaporating the refrigerant to cool process air to a temperature lower than its dew point. The dehumidifying air-conditioning apparatus further comprises a refrigerant path branched into a plurality of branched refrigerant paths (42, 43, 44) between the condenser (5) and the evaporator (1). A first heat exchanging portion (21) is disposed in the branched refrigerant path for evaporating the refrigerant under an intermediate pressure between the condensing pressure of the condenser (5) and the evaporating pressure of the evaporator (1) to cool the process air by evaporation of the refrigerant under the intermediate pressure. A second heat exchanging portion (22) is disposed in the branched refrigerant path for condensing the refrigerant under an intermediate pressure between the condensing pressure of the condenser (5) and the evaporating pressure of the evaporator (1) to heat the process air by condensation of the refrigerant under the intermediate pressure. The first heat exchanging portion (21), the evaporator (1), the second heat exchanging portion (22) are connected in the order named by paths (30, 31, 32, 33, 34).
