- the heat recovery system (30) has at least one condenser (33) adjacent to the turbine (32). Said condenser (33) allows the heat of the second fluid whose kinetic energy is used in the turbine (32) to be discharged.
- the condenser (33) discharges the waste heat of the heated fluid and the remaining waste heat from the recovery to the environment. Cooling of the fluid is provided in this way. The flow recirculation is completed by directing the cooled fluid back to the heat exchanger (31).
- An extra pump (34) can be used to improve fluid circulation in the heat recovery system (30).

- the turbine (32) condenses the second fluid, compresses it in the second flow direction (II) and increases its kinetic energy with the operation of the alternator (40). Since the second fluid is compressed, its temperature increases as well as its pressure. The second fluid, whose temperature is increased, is moved in the second flow direction (II) in the heat recovery system (30).
- the heat exchanger (31) transfers the heat of the second fluid to the first fluid in this case.
- the heated first fluid can be used as a heater in the air conditioning system (20) of the vehicle (1). Since the second fluid that transfers its heat to the first fluid in the heat exchanger (31) contains high pressure, it condenses in the condenser (33) and completes its recirculation by passing through at least one valve (36) without the need for extra pump (34).

It is ensured in this embodiment that electricity is generated through the alternator (40) by regenerative braking in cases where the vehicle (1) is going downhill or when the gas is not pressed.
- -Regenerative braking is an energy recovery mechanism that slows down a moving vehicle (1) or object by converting its kinetic energy into a form that can be used immediately or stored until it is needed. -In this way, the load on the brake pads is reduced and electrical energy can be stored here instead of the energy that is emitted as lost heat.
- the alternator (40) and the engine (10) of the vehicle (1) are connected to each other, and the alternator (40) also functions as a starter generator.
- the first drive can be given to the engine (10) of the vehicle (1) when the alternator (40) can be used as a starter generator. This eliminates the need to use the starter dynamo and reduces the manufacturing cost of the vehicle (1).
- the electrical energy required by the air conditioning system (20) in the alternative embodiments of the invention can also be provided by operating the heat recovery system (30) in the second flow direction (II). Both energy will be generated and the air conditioning system (20) will be operated through this system and the carbon dioxide emission of the vehicle (1) will decrease in this way.
- the exhaust gas heat can also be taken by the recuperator application and given to the system in another alternative embodiment of the invention. Energy recycling is improved in this way.
- the waste heat taken from the engine (10) of the vehicle (1) is converted into electrical energy through the heat recovery system (30) and used in the vehicle (1) with this whole embodiment.
