ELECTRIC OR HYBRID TRACTION VEHICLE EQUIPPED WITH AN AIR CONDITIONING SYSTEM, WITH HEAT RECOVERY FROM COOLING OF ELECTRICAL AND/OR ELECTRONIC COMPONENTS

An electric or hybrid traction vehicle is provided with a passenger compartment conditioned by means of an air conditioning system, and with electrical/electronic components which are cooled by means of a waste heat dissipation and recovery system; such system transfers the recovered heat to an additional heat exchanger for heating and/or post-heating an air flow, which is conveyed towards the passenger compartment by means of an aeraulic duct; the additional exchanger is arranged in series with, and downstream of, an evaporator of a refrigerating assembly, which cools the air flow in the aeraulic duct; by means of the heat recovered from cooling the electrical/electronic components, it is possible to post-heat the air for summer conditioning for achieving temperature setpoint and humidity setpoint.
