AIR CONDITIONING SYSTEM IN PARTICULAR FOR ELECTRIC VEHICLE APPLICATIONS

Air conditioning system, in particular for electric vehicle applications, defined by a closed circuit where coolant fluid circulates, the circuit comprising a first heat exchanger (evaporator) intended to be installed in the external environment, a second heat exchanger (condenser) intended to be installed in room or vehicle coach, a compressor arranged between said first and second heat exchangers and a lamination valve (LV) arranged symmetrically to the compressor between said second and first heat exchangers, wherein the circuit comprises a controllable valve (CV) arranged between said first heat exchanger (evaporator) and said compressor in order to maintain a fluid pressure within said first heat exchanger above a predetermined minimum threshold pressure, when said first heat exchanger works as an evaporator (heat pump mode).
