<p>A heat pump with high COP and a compact dehumidifier; the heat pump, comprising a booster (260) boosting refrigerant, an evaporator (210) cooling a low heat source side fluid (A) by the evaporation heat of the boosted refrigerant, a condenser (220) heating a high heat source side fluid (B) by the condensation heat of the boosted refrigerant, and a first heat exchanger (300a) exchanging heat between the low heat source side fluid (A) on the upstream side of the evaporator (210) and a cooled fluid, the heat exchanger (300a) further comprising a first compartment (310) allowing the low heat source side fluid (A) to flow therethrough and a second compartment (320) allowing the cooled fluid to flow therethrough having refrigerant flow paths (251A1 to A9) and (252A1 to A9) passed therethrough, wherein the refrigerant flow paths (251A1 to A9) and (252A1 to A9) are connected to each other through the condenser (220) and a first restrictor (330) and, after passing through these both compartments alternately and repeatedly, connected to the evaporator (210) through a second restrictor (250), whereby, because the refrigerant passes the first and second compartments a plurality of times, the refrigerant is less dried completely in the refrigerant flow paths passing through the first compartment.</p> |
