To provide a heat exchange system capable of securing an adjustment width of distribution to heat absorbing capacity for absorbing heat from blown air to be blown to an air-conditioning object space and heat absorbing capacity for absorbing heat from a heat absorption medium.SOLUTION: A heat exchange system 1 includes: a compressor 11; a condenser 12; a first pressure reduction valve 14; an evaporator for air conditioning 15; a second pressure reduction valve 17 disposed in parallel with the first pressure reduction valve 14 at a downstream side of the condenser 12; and an evaporator 18 for a first apparatus to absorb heat from a heat generation apparatus 63 and the like through a low temperature-side heat medium. The heat exchange system 1 includes an evaporator 20 for a second apparatus to adjust a heat absorption amount from the low temperature-side heat medium by heat exchange of a refrigerant with the low temperature-side heat medium. The heat exchange system 1 is constituted to adjust distribution of heat absorbing capacity for absorbing heat from blown air and heat absorbing capacity for absorbing heat from the low temperature-side heat medium by changing a heat exchange amount in one of heat exchangers of the evaporator 18 for the first apparatus and the evaporator 20 for the second apparatus.SELECTED DRAWING: Figure 1 【課題】空調対象空間へ送風する送風空気から吸熱する吸熱能力と吸熱媒体から吸熱する吸熱能力との配分の調整幅を確保可能な熱交換システムを提供する。【解決手段】熱交換システム１は、圧縮機１１と、凝縮器１２と、第１減圧弁１４と、空調用蒸発器１５と、凝縮器１２の下流で第１減圧弁１４と並列に配置され第２減圧弁１７と、低温側熱媒を介して発熱機器６３等から吸熱する第１機器用蒸発器１８と、を備える。熱交換システム１は、冷媒を低温側熱媒体と熱交換させて低温側熱媒体からの吸熱量を調整する第２機器用蒸発器２０を備える。熱交換システム１は、第１機器用蒸発器１８および第２機器用蒸発器２０の一方の熱交換器における熱交換量を変化させることで、送風空気から吸熱する吸熱能力および低温側熱媒体から吸熱する吸熱能力の配分を調整するように構成されている。【選択図】図１
