The present invention relates to a heat pump which enables the waste heat generated in the electric engine vehicles to be used in heating cycle of the vehicle cabin. Background of the Invention
In motor vehicles, there are air conditioning systems which enables to maintain the cabin air within comfort conditions so that the passengers can travel comfortably, and which is designed to decrease the ambient temperature by drawing heat from a medium using cooking cycle and provide fresh air to the medium by removing the excess humidity. Today, the air conditioning systems formed for the vehicles are generally formed by sending heated or cooled air inside the vehicle cabin. Heat is generated on the engine during the operation of engine in motor vehicles, and an engine cooling system (4) is formed which is comprised of a radiator, fan and coolant in order to discharge the generated heat. The heat generated in the engine is absorbed by the coolant sent onto the engine, and the heated water is cooled upon the contact of the air on the radiator. Especially during winter months, this waste heat generated in the engine can be included in the heat pump system in order to heat the vehicle cabin, and therefore energy saving can be provided on the air conditioner. In motor vehicles operating with fuel, there are systems for using the heat generated in the engine for heating the vehicle cabin. In electric vehicles wherein the air conditioning is realized by using heat pump, the condenser unit used as condenser comprises an additional electrical solenoid controlled expansion valve (e-TVX) and the electrical solenoid controlled expansion valve is converted into the evaporator and thus the heat pump cycle is completed. In electric engine heat pump systems formed in such way, the waste heat generated in the electric engine and the connected components is not preferred due to the amount of the generated waste heat being less than the ICS systems, the temperature value being low and complex systems being used for solving the problem. As a result of this, energy is consumed in high amounts for cabin air conditioning in electric vehicles, and this negatively affects the vehicle performance.
The Problems Solved with the Invention
The objective of the present invention is to provide a high efficiency heat pump for electric vehicles which allows the waste heat generated in engine and connected components in electrical vehicles being used in heating the cabin.
Another objective of the present invention is to provide a high efficiency heat pump for electric vehicles which enables the waste heat generated in the engine and the connected components to reach the sufficient temperature value for heating the vehicle cabin by increasing the COP value of the waste heat.

The coolant (32) becoming gas after being vaporized in the evaporator (33) is pressurized with the compressor (34), and it gives its heat to the air mixture (31) in the heating condenser (35) and it becomes liquid again. The coolant (32) cooling in the heating condenser (35) comes over the heat exchanger (5) without being cooled in the outer condenser (36), In the engine cooling system (4), the heat of the electric engine and the engine components is removed and the heated coolant (41) is sent to the heat exchanger (5).
