Abstract

In an air-conditioning system for motor vehicles, the radiator for heating the passenger compartment is excluded from connection to the circuit for cooling the engine when heating of the passenger compartment is not required. In this condition, a mixing valve is set in an intermediate position, in which part of the flow of air leaving the evaporator of the system flows directly in the passenger compartment of the motor vehicle, keeping it cooled, while part of the flow of air leaving the evaporator flows through the aforesaid heating radiator, which in this condition functions as accumulator of cold. When the cooling circuit is temporarily deactivated, cooling of the passenger compartment can be ensured by the radiator, that yields the previously accumulated cold.
