The invention concerns a motor vehicle cooling and depolluting device designed for conditioning said vehicle passenger compartment and for cooling its cylinder block (22). The elements of the device are connected through a main tube (25) containing an antifreeze liquid. The device also comprises a temperature and pressure control valve (17), to maintain a constant pressure in the cylinder block (22) and located downstream of the cylinder block (22), a ventilated water-air exchanger (6) enabling a motor vehicle passenger compartment to be cooled, a ventilated water-air exchanger (1) enabling a motor vehicle engine compartment to be cooled, at least a cold water tank (3) for cooling upon start-up of the motor vehicle and located between the ventilated water-air exchanger (6) and the evaporator (24) and a solenoid valve (9) for controlling the temperature inside the motor vehicle passenger compartment and located downstream of the ventilated water-air exchanger (6). A water-fume exchanger (21), located downstream of a water-fume exchanger (20), serves to depollute the exhaust gases of an engine (18) by cooling said exhaust gases and condensing its hydrocarbon residues as well as by trapping the particles of said exhaust gases.
A device for cooling and depolluting a motor vehicle, which is intended for air-conditioning the passenger compartment of said vehicle and for cooling its engine block (22), and the elements of which are connected by a main tube (25) containing an antifreeze fluid, comprising a pump (13), an absorber (23), a high-pressure generator (19), a low-pressure generator (4), a condenser (5), an evaporator (24), characterized in that it comprises a temperature-pressure regulating valve (17) located downstream of the engine block (22), for maintaining a constant pressure/temperature in the part of the cooling circuit around the engine (18) inside said engine block (22), thus preventing water from evaporating inside said part of the cooling circuit and making it possible to sustain cooling of said engine block (22).
