Abstract
A refrigeration unit applied, for example, to an air conditioning system for a car has a condenser, an expansion valve, and an evaporator interposed in a refrigerant circulation passage in the order named. The circulation passage includes a fluid-flowing area for a liquid refrigerant from the condenser to the expansion valve, and a gas-flowing area mainly for a gaseous refrigerant from the evaporator to the compressor. The refrigeration unit is provided with a detector for detecting the presence of the gaseous refrigerant in the liquid-flowing area. If the detector detects the gaseous refrigerant, a warning light indicative of a refrigerant leak is turned on.
