Abstract
In the heating mode, the fluid in the air conditioning circuit flows in a bypass branch avoiding the condenser. The evaporator then receives the fluid in the gaseous state and acts as a heat exchanger for dissipating the heat produced in the compressor. The heat dissipated by the evaporator can be used for heating the cabin when that which is produced by the propulsion engine of the vehicle is insufficient. In addition, the fluid pressure at the inlet of the evaporator, and therefor the calorific power produced by the latter, is adjusted by a pressure regulator disposed in the bypass branch.
