An air-conditioning system of a motor vehicle, including: a primary, gas compression cooling circuit set entirely in the engine compartment; a secondary cooling circuit that takes cold from an evaporator or chiller of the primary circuit and conveys it to a heat exchanger in the passenger compartment; the system has elements for setting in fluid communication the primary circuit, the secondary circuit and a circuit for heating the passenger compartment. The heating circuit has a heat exchanger which is used as a heater when the heating system is activated, and can be used as additional mass for cooling air of the passenger compartment to meet the peak cooling requirement. |
