A method for controlling a heat pump system. The heat pump system includes a compressor for compressing a working fluid of the heat pump system and an electric motor for providing an output torque for driving the compressor. The method includes the steps of recovering heat emitted from the electric motor by heating the working fluid, providing a first control mode and a second control mode for the electric motor, and controlling the electrical motor in a way creating higher heat losses of the electric motor for a given output torque of the electric motor in the second control mode than in the first control mode.

An engine system including: an engine configured to output shaft power by burning fuel, and a system main portion configured to operate using the shaft power of the engine. The engine system further includes: an operation controlling unit, and a power source unit configured to convert commercial power to operating power and supply the operating power to the operation controlling unit. The power source unit includes: a system main portion-side power source unit configured to supply operating power for controlling the operation of the system main portion, and an engine-side power source unit configured to supply operating power for controlling the operation of the engine. The system main portion-side power source unit and the engine-side power source unit are provided individually and separately from each other.

A refrigeration cycle device includes a compressor, a heating radiator, a heat medium radiator, a decompressor, an evaporator, and a radiation amount adjuster. The heating radiator is configured to allow a high-pressure refrigerant to release heat to a heat exchange target fluid. The heat medium radiator is configured to allow the high-pressure refrigerant to release heat to a high-temperature side heat medium. The radiation amount adjuster is configured to adjust heat radiation amount radiated from the high-pressure refrigerant to the heat exchange target fluid at the heating radiator. In a heating mode, the radiation amount adjuster is configured to adjust the heat radiation amount at the heating radiator to be larger than a heat radiation amount at the heat medium radiator. In a cooling mode, the radiation amount adjuster is configured to adjust the heat radiation amount at the heating radiator to be lower than that in the heating mode.

The thermal batteries improves the operation of electrical equipment by storing energy in thermal materials and changing it to power instead of storing it in chemical energy and having to change the chemical energy to power the machine. The battery can use internal storage on one or both sides of the generator to power the the machine or can use the thermal energy in the environment to power the generator. The battery takes the energy from the high temperature storage on one side and moves it through the generator and sends the excess heat to the low temperature side. The high temperature sides can change to the low temperature side by moving the battery or changes to the operating environment of the machine. The battery extends its operation because it does not have energy limited by the size of the plates and can continue its operation and is charged by sending in new material at the necessary temperature or by increasing the temperature of the material in the battery to power the machine.

An in-vehicle absorption heat pump device includes: a regenerator including a gas-liquid separation unit that separates a diluted absorbent containing a refrigerant into the refrigerant and a concentrated absorbent separated from the diluted absorbent; a condenser that condenses a refrigerant vapor separated from the diluted absorbent in the gas-liquid separation unit; an evaporator that evaporates the refrigerant condensed in the condenser; an absorber that causes the refrigerant evaporated by the evaporator to be absorbed into the concentrated absorbent separated from the diluted absorbent in the gas-liquid separation unit; and a storage tank that stores both the diluted absorbent discharged from the absorber and the refrigerant discharged from the evaporator. The storage tank is integrally provided below both the absorber and the evaporator, and communicates with both the absorber and the evaporator.

Proposed is a gas heat-pump system capable of supplying recirculation exhaust gas to an engine using an exhaust gas turbocharger and thus actively controlling an amount of the flowing recirculation exhaust gas and pressure thereof.

Methods and apparatuses for expelling heat may be provided. For example, an apparatus may comprise a rotating assembly, a support structure, a condenser water tank, and a control system. The apparatus may rotate the rotating assembly such that tanks of the assembly are rotated into and out of the condenser water tank. The rotation may be self-starting and controlled by a control system.
