Document Type and Number:
WIPO Patent Application WO/2024/095762
Kind Code:
A1
Abstract:
Provided are a control system, a moving body, a control method, and a control program capable of reliably detecting leakage of a refrigerant. A control system (50) applied to a refrigerator that is provided in a moving body and that cools the interior of a cargo compartment of the moving body comprises: a gas detecting unit (51) that is installed in the cargo compartment, in which an evaporator of the refrigerator is provided, and that acquires a gas detection value of a refrigerant sensor for detecting leakage of a gas including a refrigerant gas; an operating state detecting unit (52) which acquires operating state detected values of at least two of a low-pressure pressure sensor which is provided in the refrigerator to detect a low pressure of the refrigerant on an outlet side of the evaporator, a high-pressure pressure sensor for detecting a high pressure of the refrigerant on an outlet side of a compressor of the refrigerator, and an evaporator outlet temperature sensor for detecting an outlet temperature of the evaporator; and a determining unit (53) for determining, on the basis of the gas detection value and the operating state detected values, whether a medium that has leaked into the cargo compartment is the refrigerant gas.
