Abstract
An electric or hybrid traction vehicle is provided with a passenger compartment conditioned using an air conditioning system, and with electrical/electronic components which are cooled by 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 via 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.
