Title:
COOLING SYSTEM FOR MOBILE BODY, MOBILE BODY WITH COOLING SYSTEM, AND COOLING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/145101
Kind Code:
A1
Abstract:
A purpose of the present invention is to establish an efficient and stable cooling cycle. This cooling system for a mobile body includes: a compressor; a condenser; an expansion valve; an evaporator; a flow rate adjusting device that adjusts a flow rate for when a cooling fluid dependent on the outside environment of the mobile body is guided to the condenser; an environment temperature acquisition sensor that detects an environment situation for acquiring an environment temperature to which the condenser is exposed by the cooling fluid; a pressure sensor that detects a pressure of a coolant in the condenser; a temperature sensor that detects a temperature of the coolant on the downstream side of the condenser; and a control unit that executes a first process for adjusting, on the basis of the environment temperature and an output of the pressure sensor, the flow rate of the cooling fluid such that the pressure of the coolant in the condenser is greater than a saturation pressure of the coolant at the environment temperature, and a second process for adjusting, on the basis of the output of the pressure sensor and an output of the temperature sensor, a degree of opening of the expansion valve such that the coolant is in a subcooled state on the downstream side of the condenser.
