An integrated thermal management system for fuel cell mobility vehicles, may include a hydrogen tank configured to store hydrogen supplied to a fuel cell stack, a first turbine rotated by the pressure of the hydrogen discharged from the hydrogen tank, a refrigerant circulation line configured such that a refrigerant circulates therealong and a compressor, a condenser, an expansion valve and an evaporator are provided thereon, a second turbine mounted in the refrigerant circulation line and rotated by the high-pressure refrigerant discharged by the compressor, and a blower configured to pressurize ambient air using the rotation force of the first turbine, the second turbine or an electric motor and to supply the pressurized ambient air to an indoor air conditioning unit or the fuel cell stack.

A vehicle system includes an electric motor that also operates as a generator. A torque transfer mechanism is attached to the electric motor and a second torque transfer mechanism is connected via a disconnect mechanism. An AC compressor is attached to the first torque transfer mechanism via a clutch, which has an open position and a closed position. During recuperation, the second torque transfer mechanism is connected to the first torque transfer mechanism and the clutch is closed, and the compressor is driven by the motor. During stand-still, the second torque transfer mechanism is disconnected from the first torque transfer mechanism, and the compressor is driven by the motor. During drive operation, the second torque transfer mechanism is connected to the first torque transfer mechanism, and the clutch is open such that the compressor is not driven, but the system continues to provide cool air to the vehicle cabin.

The car suspension system of current invention comprises a damper for the absorption of the forces which is exerted on a vehicle's cabin. In this model, there is no need for a compressor, belt and a power output of an engine to produce coolness, however the force of the car suspension system is utilized; that is to say, damper and compressor juxtapose in parallel to the side of the spring system which aids to damp the vibration in order to maintain stability and provides a comfortable temperature in the car cabin on hot days at no cost and drawbacks which will be discussed later.
