HEAT PUMP SYSTEM

PROBLEM TO BE SOLVED: To provide a heat pump system capable of reliably prevent unevenness of the amount of solution circulating through each of a compression cycle and an absorption cycle.SOLUTION: A heat pump system includes a compression cycle where refrigerant circulates and an absorption cycle where solution circulates, makes the solution absorb the refrigerant evaporated in an evaporator 14 in the compression cycle by an absorber 20 to make them circulate in the absorption cycle, supplies the refrigerant separated from the solution to the compression cycle after being subjected to heat exchange with waste heat in a regenerator 24 in the absorption cycle, and includes: a gas-liquid separator for refrigerant 11 arranged on a discharge side of a compressor 10 in the compression cycle; and a second solution return pipe 36 returning the solution reserved in the gas-liquid separator for refrigerant 11 to the absorption cycle.SELECTED DRAWING: Figure 1 【課題】圧縮サイクルと吸収サイクルとをそれぞれ循環する溶液の量の偏りを確実に防止することのできるヒートポンプシステムを提供する。【解決手段】冷媒が循環する圧縮サイクルと溶液が循環する吸収サイクルとを備え、圧縮サイクルの蒸発器１４で蒸発した冷媒を吸収器２０で溶液に吸収させて吸収サイクル内を循環させ、吸収サイクルで再生器２４で排熱と熱交換した後、溶液から分離した冷媒を圧縮サイクルに供給するものであり、圧縮サイクルの圧縮機１０の吐出側に配置される冷媒用気液分離器１１と、冷媒用気液分離器１１に溜まった溶液を前記吸収サイクルに戻す第２溶液戻り用配管３６とを備えている。【選択図】図１
