<p>PROBLEM TO BE SOLVED: To provide a heat exchange system capable of efficiently and stably cooling a heat source in both cooling and heating.SOLUTION: A heat exchanger performing heat exchange among an air conditioning refrigerant Y1, a cooling refrigerant Y2 and an air flow Y3 includes heat exchange amount adjustment means of adjusting a heat exchange amount between the air conditioning refrigerant Y1 and the cooling refrigerant Y2. The heat exchange amount adjustment means reduces the heat exchange amount between the air conditioning refrigerant Y1 and the cooling refrigerant Y2 when an air conditioning refrigerant circuit functions as cooling, and increases the heat exchange amount between the air conditioning refrigerant Y1 and the cooling refrigerant Y2 when the air conditioning refrigerant circuit functions as heating.</p> |
