Mechanical power of the cooling compressor is converted to thermal power.

  • the said system comprises out-vehicle heat exchanger, expansion valves, in- vehicle heat exchanger, a heater, and valves for switching between the refrigeration and heating systems.
  • Chinese utility model document no. CN202254031 another application known in the state of the art, discloses an air conditioning system for electric vehicles operated by a heat pump.
  • the said system can be operated in 5 different working modes of refrigeration, heating, low temperature heating, wind defrosting/demisting and low-temperature defrosting.
  • the motor cooling system values in electric vehicles is suitable for cold water generation system condenser cooling, an additional condenser component is used and this ruins the cost, weight and layout convenience of the system.

  • At least one air conditioning module heating coil (4) which enables to heat the cabin
  • At least one cooling compressor (7) which is in the vehicle air conditioning and battery cooling system (A) and increases temperature of the coolant by pressurizing it,
  • 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 thermostat (11) which deactivates the radiator (2) when the outer environment is cold
  • At least one cabin and battery coolant line (12) which carries the coolant coming from the cabin air conditioning system (K) and the battery (B) group,

  • Electric vehicle electric motor (M) operation temperatures are below the cooling system condenser condensing temperature. Therefore, after the liquid-phase coolant (generally ethylene glycol added water) used for cooling the electric motor (M) leaves the electric motor (M), it is connected to the inlet of the two- phase and two-fluid heat exchanger group (5), and after collecting the waste heat of the motor (M), it also collects the condensing heat of the cooling system, thereby it can bring the heat to a higher value. This value is equal to the engine coolant temperature of an internal combustion engine for general operation points.
  • liquid-phase coolant generally ethylene glycol added water
  • the water heated in the heat exchanger (5) is heated by being passed through the heating coil (4) provided in the cabin air conditioning system (K) in the known art. Since a liquid having values near the heating water temperature and flow rate values of the vehicles with internal combustion engines is circulated and since heating capacity of the heating coil (4) is much higher than necessary due to the excessive waste heat value of these vehicles, there is no need for making a change in this component.
  • the by-pass line (10), and the thermostat (11) system that closes the line going to the radiator (2) at very low ambient temperature, which are used in internal combustion engines, can be used as the same way. This way, the heat collected from the motor (M) and the batteries (B) and all of the heat collected from the cooling system can be used for heating the cabin.
  • the by-pass line (10) and the thermostat (11) are deactivated.
  • the heat collected from the cabin air conditioning system (K) and battery (B) group via the coolant line (12) is drawn by the two-phase and two- fluid cold heat exchanger (9); its temperature is increased by the cooling compressor (7); and it is transferred to the motor cooling water by condensation in the two-phase and two-fluid hot heat exchanger (5).
  • the heated water passes through the radiator (2) and upon being cooled by means of the radiator fan (3) all waste heat is discharged to the outer environment.
  • the circulation in the hot water line is enabled by the motor cooling system pump (6).
  • the cabin temperature is reduced by the cooling coil (16), and the hated water is delivered from the coil (16) to the two-phase and two-fluid cold heat exchanger (9) by means of the cold water circulation pump (15).
  • the temperature of the hot water here is used for evaporating the pressurized coolant, and the evaporated coolant is expanded on the compressor (7) (by using the compressor as a turbine); and by operating the electric motor coupled to the compressor (7) as a generator, electricity is generated and the batteries (B) are charged.
