Abstract (en)

[origin: WO2016076809A1] The present invention relates to a heat pump system for electric vehicles (1); which, in electric vehicles, enables to cool the motor (M) and the battery (B), and enables operation of the cabin air conditioning system; and comprises at least one air conditioning module heating coil (4) which enables to heat the cabin, at least one two-phase and two-fluid hot heat exchanger (5) which collects the waste heat of the motor, at least one two-phase and two-fluid cold heat exchanger (9) which collects the waste heat of the cabin air conditioning system (K) and the battery (B) group, at least one by-pass line (10) and thermostat (11) which deactivate the radiator (2) when the outer environment is cold, at least one cabin air conditioning module fan (13) which, when the vehicle is not running, cools the cabin by transferring the excess heat within the cabin to the coolant, at least one cooling coil (16) which reduces cabin temperature.
