摘要： PROBLEM TO BE SOLVED: To provide a heat pump having a high coefficient of performance and a dehumidifier having low energy consumption per dehumidification capacity. SOLUTION: The heat pump comprises a booster 260 for refrigerant, a condenser 220 for heating high heat source fluid by condensing the refrigerant, an evaporator 210 for cooling a low heat source fluid by evaporating the refrigerant, and a heat exchanging means 300 provided in a refrigerant passage connecting the condenser 220 and the evaporator 210 in order to evaporate and condense the refrigerant with an intermediate pressure between the condensation pressure of the condenser 220 and the evaporation pressure of the evaporator 210 thus cooling the low heat source fluid through evaporation with intermediate pressure and heating the low heat source fluid through condensation with intermediate pressure wherein the low heat source fluid is subjected to cooling through the heat exchanging means 300, cooling through the evaporator 210 and heating through the heat exchanging means 300 in this order. The low heat source fluid can be precooled through the heat exchanging means before being cooled through the evaporator and the precooled cold heat can be recovered from the temporarily cooled low heat source fluid through the evaporator.

摘要： PROBLEM TO BE SOLVED: To simply provide an air conditioner capable of improving dehumidifying efficiency and besides making the outside size of an indoor machine compact. SOLUTION: Heat exchange units 3, 4, and 5 are situated in a manner to surround a supply impeller wheel 6. Air sucked in a casing 2 through indoor air intakes 7 and 8 by a flow of air generated through rotation of the supply impeller wheel 6 is precooled by precoolers 3b, 4b, and 5b of the heat exchange units 3, 4, and 5 and reduced in temperature. Precooled air is cooled and dehumidified by main heat exchangers 3a, 4a, and 5a and thereafter, heated by reheaters 3c, 4c, and 5c. As a result, air reduced in only humidity is supplied in a room through an air outlet 9 through a guide flow passage 10.
