Title:
DEVICE FOR COMPENSATING LEAKS IN A MOTOR VEHICLE AIR CONDITIONING SYSTEM OR A MOTOR A REFRIGERATING VEHICLE COOLING SYSTEM USING CARBON DIOXIDE AS REFRIGERANT
Document Type and Number:
WIPO Patent Application WO2004051162
Kind Code:
B1
Abstract:
The invention concerns a device comprising at least one carbon dioxide cylinder (7) and a low flow rate expansion valve (8) arranged as an auxiliary system of the low pressure portion of said system. Said leak-compensating device has a function equivalent to a cylinder, installed in the motor vehicle air conditioning or the refrigerating vehicle cooling system itself when the refrigerant used is a halogenated hydrocarbon. Said device, with the addition of two valves (9) and (10), enables compensation of leaks in the circuit for the whole life span of the vehicle, by standard exchange of the CO2 cylinder, without any intervention on the system itself (figure 3). The invention is applicable to motor vehicle air conditioning or refrigerating vehicle cooling systems using carbon dioxide as refrigerant.
