The purpose of the present invention is to establish an efficient and stable cooling cycle. A cooling system for a moving body is provided with: a compressor; a condenser; an expansion valve; an evaporator; a flow rate adjusting device for adjusting the flow rate when a cooling fluid depending on the external environment of the moving body is guided to the condenser; an ambient temperature acquisition sensor for detecting an ambient condition for acquiring an ambient temperature at which the condenser is exposed by the cooling fluid; a pressure sensor that detects the pressure of the refrigerant in the condenser; a temperature sensor that detects the temperature of the refrigerant on the downstream side of the condenser; and a control unit that executes a first process for adjusting the flow rate of the cooling fluid so that the pressure of the refrigerant in the condenser is greater than the saturation pressure of the refrigerant at the ambient temperature, on the basis of the ambient temperature and the output from the pressure sensor, and a second process for adjusting the flow rate of the cooling fluid so that the pressure of the refrigerant at the ambient temperature is greater than the saturation pressure of the refrigerant at the ambient temperature. And a second process for adjusting the opening degree of the expansion valve on the basis of the output of the pressure sensor and the output of the temperature sensor so that the refrigerant on the downstream side of the condenser is in a supercooled state.

    本发明的目的在于使高效且稳定的冷却循环成立。移动体用冷却系统具备:压缩机;冷凝器;膨胀阀;蒸发器;流量调整装置,对依赖于移动体的外部环境的冷却用流体被引导至所述冷凝器时的流量进行调整;环境温度取得用传感器,检测用于取得冷凝器通过冷却用流体而被暴露的环境温度的环境状况;压力传感器,检测冷凝器中的制冷剂的压力;温度传感器,检测冷凝器的下游侧的制冷剂的温度;以及控制部,执行第一处理和第二处理,该第一处理是根据环境温度和压力传感器的输出,对冷却用流体的流量进行调整使得冷凝器中的制冷剂的压力比环境温度下的制冷剂的饱和压力大的处理,该第二处理是根据压力传感器的输出和温度传感器的输出,对膨胀阀的开度进行调整使得在冷凝器的下游侧制冷剂成为过冷状态的处理。
