To establish an efficient and stable cooling cycle.SOLUTION: A cooling system for mobile body includes: a compressor; a condenser; an expansion valve; an evaporator; a flow rate adjusting device which adjusts a flow rate when fluid for cooling depending on an external environment of a mobile body is guided to the condenser; a sensor for environmental temperature acquisition which detects environmental circumstances for acquiring the environmental temperature at which the condenser is exposed by the fluid for cooling; a pressure sensor for detecting pressure of coolant in the condenser; a temperature sensor for detecting temperature of the coolant on the downstream side of the condenser; and a control part which performs first processing that adjusts a flow rate of the fluid for cooling so that pressure of the coolant in the condenser is greater than saturation pressure of the coolant at the environmental temperature on the basis of the environmental temperature and the output of the pressure sensor, and second processing that adjusts an aperture by the expansion valve so that the coolant is in a sub-cool state on a downstream side of the condenser on the basis of the output of the pressure sensor and output of the temperature sensor.SELECTED DRAWING: Figure 3
