To provide a heat pump system which secures heat absorbing performance of a heat sink in a low-temperature environment, and can respond to heating operation in a wider temperature range.SOLUTION: A heat pump system 1 includes a vapor compression type refrigeration cycle 10, and an air heating unit 30, and is structured so as to execute heating operation for heating blown air by using heat of a discharge refrigerant compressed by a refrigerant compressor 11 of the refrigeration cycle 10 as a heat source. The air heating unit 30 compresses air sucked from an air intake port 32 by an air compression/expansion machine 31, and generates and supplies heat to a chiller 17 side of the refrigeration cycle 10 through a low-temperature side heat medium in a low-temperature side heat medium circuit 25.SELECTED DRAWING: Figure 1

    【課題】低温環境における吸熱器の吸熱性能を確保して、より広い温度範囲で暖房運転に対応可能なヒートポンプシステムを提供する。【解決手段】ヒートポンプシステム1は、蒸気圧縮式の冷凍サイクル10と、空気加熱ユニット30を有しており、冷凍サイクル10の冷媒圧縮機11で圧縮した吐出冷媒の熱を熱源として送風空気を加熱する暖房運転を実行可能に構成されている。空気加熱ユニット30は、空気吸込口32から吸い込んだ空気を、空気圧縮膨張機31で圧縮して熱を発生させて、低温側熱媒体回路25の低温側熱媒体を介して、冷凍サイクル10のチラー17側に供給する。【選択図】図1
