Abstract: A system for warming an engine. The system includes an engine coolant system that directs warm engine coolant to the engine to heat the engine. A heat pump system warms the engine coolant.

Abstract: A transport refrigeration system (TRS) and method of operating a TRS having a sorption subsystem are disclosed. The TRS includes a refrigeration subsystem and a sorption subsystem. The refrigeration subsystem includes a refrigerant, a compressor, a refrigerant condenser, a refrigerant expansion device, and a refrigerant evaporator in fluid communication such that the refrigerant can flow therethrough. The sorption subsystem includes a heat transfer fluid, a heat source, a boiler, a sorption condenser, a sorption expansion valve, a sorption evaporator, and a pump in fluid communication such that the heat transfer fluid can flow therethrough. The sorption evaporator is in thermal communication with the refrigeration subsystem.

Abstract: A liquid cooling method for a hydroelectric generator which cools the winding of the rotor via a primary cooling liquid circuit, the cooling liquid being maintained in the circuit by the produced centrifugal force. The dissipation of the thermal energy takes place via a secondary cooling liquid which flows once vertically through the system. Accordingly, the thermal exchange takes place via a co-rotating heat exchanger in the center of the rotor. A device for carrying out such a method is also disclosed.

Abstract: A heat exchanger is for use in an energy recovery system to be mounted on a vessel including an engine, a supercharger and an economizer, the heat exchanger including: a first heat section for heating a working medium by supercharged air from the supercharger; a second heat section for heating the supercharged air by steam generated by the economizer before the supercharged air flows into the first heat section; and a third heat section for heating the working medium having been heated in the first section by the supercharged air which is to be heated in the second section.

Abstract: The present invention relates to a venting tank, suitable for being fitted in a cooling system of a motor vehicle and defining an inner space intended for receiving a coolant, the venting tank including at least one inlet and at least one outlet for the coolant which are arranged below a minimum liquid level when the vehicle is in service, wherein the venting tank also includes, opposite the inlet or at least some of the inlets, a member for guiding the coolant, penetrating into the inner space via the inlet, following a flow directed toward a lower wall of the venting tank opposite the flow arriving through the inlet, and forming a 180-degree arc. The invention also relates to a motor-vehicle cooling system provided with such a venting tank.

Abstract: A control method of an air conditioner system for an electric vehicle may include circulating the refrigerant by sensing actuation of the air conditioner system while driving the electric vehicle in a state where a start of the electric vehicle is turned on, circulating and cooling the cooling water through actuation of a water pump and a cooling fan in a cooling module that includes an engine radiator, the intercooler radiator, the water-cooled condenser, and the air-cooled condenser, and controlling actuation speeds of the water pump and the cooling fan based on whether the electric vehicle stops after suddenly accelerating in a state where the air conditioner system is actuated or stops in a state where the air conditioner system is turned off after travelling, and/or based on whether an air conditioner pressure and a cooling water temperature are within predetermined set values.

Abstract: A composite heat exchanger system includes an air cooled condenser 5, a sub-radiator 3 and a main radiator 2, and it is formed in a state where a tank 3a of the sub-radiator 3 is communicated with a tank 2a of the main radiator 2. A water cooled condenser 4 is contained in a tank 3b of the sub-radiator 3. A part of flowing medium that is cooled down by the main radiator 2 is introduced in the sub-radiator 3 to cool flowing medium of the water cooled condenser 4. The flowing medium that is cooled down by the water cooled condenser 4 is introduced in the air cooled condenser 5 to be cooled.

Abstract: A system for providing cooling incorporates a combustion engine (1, 2) equipped with an exhaust heat recovering heat exchanger (3) which is adapted to transfer heat energy to a heat-driven chiller (4) in which cooling can be extracted from one or more heat carrier circuits (8). The cooling thereby provided may be used for cooling of engine charge air or compressor air and/or for providing cooled air for human comfort and/or for goods. Use of heat energy derived from the engine exhaust gas flow can be added to the system. Exhaust or air intake heat exchangers may provide silencing or gas cleaning of air or gas. The system may, e.g., be applied to vehicles. Compact absorption chillers may be used in the system. A method for providing cooling is disclosed.
