The present invention relates to a gas heat pump system. The gas heat pump system, according to one embodiment of the present invention, comprises: an air conditioning module comprising a compressor, an outdoor heat exchanger, an expansion apparatus, an indoor heat exchanger and a refrigerant line; and an engine module comprising an engine for combusting a mixture of fuel and air, thereby providing power for driving the compressor. The engine module comprises: a mixer for mixing and discharging the air and fuel; a supercharging means for receiving the mixture discharged from the mixer, compressing same, and then discharging same; an intercooler for receiving the mixture compressed in the supercharging means, cooling same by a heat exchange method, increasing the density thereof, and then discharging same; an adjustment means for receiving the mixture discharged from the intercooler, adjusting the quantity thereof, and then supplying same to the engine; and an exhaust gas heat exchanger for exchanging heat between a coolant and exhaust gas discharged from the engine, wherein the exhaust gas heat exchanger is directly connected to an exhaust manifold of the engine.

A controller includes: a control unit configured to calculate a control command value of an opening degree of a solenoid valve to control an opening degree of the solenoid valve; and an acquisition unit configured to acquire an estimated amount and a target amount of a working fluid in a labyrinth chamber, and a rotation speed of a drive shaft. The control unit calculates a final control command value based on a feedback control command value and a feedforward control command value, and controls the solenoid valve, the feedback control command value being calculated based on deviation between the estimated amount and the target amount, the feedforward control command value being used to maintain a rotation speed of a fan constant based on the estimated amount and the rotation speed of the drive shaft.

A cooling system includes a first cooler, a second cooler, a fan positioned to drive air through the first cooler and the second cooler, and a baffle system. The baffle system includes a baffle and an actuator. The baffle is positioned to facilitate selectively restricting airflow through at least a portion of the first cooler. The actuator is positioned to facilitate reconfiguring the baffle between (i) a first orientation where the baffle does not restrict the airflow through the portion of the first cooler and (ii) a second orientation where the baffle restricts the airflow through the portion of the first cooler, thereby diverting additional airflow through the second cooler.

An electric vehicle including the Rankine cycle in which a circulation system of working fluid is formed is proposed. The Rankine cycle includes a pump configured to circulate the working fluid along the circulation system, a heat source comprising a battery unit, a motor unit, and a solar panel unit to transmit thermal energy to the working fluid circulated by the pump, a power generating unit provided on a path of the circulation system to generate electric energy through the thermal energy of the working fluid passing through the heat source, and a radiator configured to perform a heat exchange process between the working fluid passing through the power generating unit and outside air. The Rankine cycle further includes a flow distributor to distribute the working fluid circulated by the pump to at least any one of the battery unit, the motor unit, and the solar panel unit.

Methods and systems are provided for reducing ice formation in a charge air cooler. In one example, a method includes, operating a radiator fan of a vehicle in a first direction to cool an engine of the vehicle, and reversing a direction of rotation of the radiator fan to blow heated air towards a charge air cooler, the charge air cooler arranged proximate a radiator of the vehicle. Operating the radiator fan in a first direction may be based on the engagement of one or more gears of a transmission of the vehicle while operating the radiator fan in the reverse direction may be based on an engine temperature condition, one or more ambient weather conditions, and an engine idle condition.
