A heat pump system is provided with a heat pump cycle (10), a heating unit (30), a low-temperature-side heat medium circuit (40), and a control unit (70). A heat pump cycle is provided with a compressor (11), a condenser (12), a decompression unit (14b), and an evaporator (16). The heating unit heats the blown air blown to the space to be air-conditioned, using the heat of the high-pressure refrigerant radiated by the condenser as a heat source. The low-temperature-side heat medium circuit is configured so as to circulate a low-temperature-side heat medium that absorbs heat by the refrigerant in the evaporator, and has heat source devices (42, 45, 46) and heat adjustment units (41, 44, 47). The control unit controls the rotation speed (Nc) of the compressor and the operation of at least one of the heat source and the heat adjustment unit to adjust the temperature (Tw1) of the low-temperature-side heat medium such that the amount of heat movement for heating the blown air by the heating unit approaches a predetermined target value.

    热泵系统具有热泵循环(10)、加热部(30)、低温侧热介质回路(40)和控制部(70)。热泵循环具有压缩机(11)、冷凝器(12)、减压部(14b)和蒸发器(16)。加热部将在冷凝器被散热的高压制冷剂所具有的热作为热源来对向空调对象空间吹送的送风空气进行加热。低温侧热介质回路构成为供在蒸发器被制冷剂吸热的低温侧热介质循环,并具有热源装置(42、45、46)和热量调节部(41、44、47)。控制部控制压缩机的转速(Nc)、热源和热量调节部中的至少一方的工作来调节低温侧热介质的温度(Tw1),以使得用于在加热部对送风空气进行加热的热移动量接近预先确定的目标值。
