Abstract: A heat recovery system captures, stores, and releases waste heat from an exhaust. The system includes a first exchanger that removes waste heat from the exhaust and transfers it to a heat transfer fluid. A second heat exchanger transfers at least a portion of the waste heat from the heat transfer fluid to a storage device. The storage device continuously stores the waste heat until a predetermined temperature is obtained. A pump draws flow of the heat transfer fluid from the first heat exchanger to the second heat exchanger. A valve directs flow of the heat transfer fluid into the storage device during a charge mode and out of the storage device during a discharge mode.

Abstract: A system may include a first heat exchanger, a pumping device, and a valve. The pumping device may be in fluid communication with the first heat exchanger. The valve may receive a fluid from the pumping device and may be movable between a first position allowing the fluid through a first flow path and a second position to allow the fluid to flow through a second flow path. The first heat exchanger may be in heat transfer relation with an energy storage device such that heat may be extracted from the energy storage device when the valve is in the first position. Heat may be transferred from the first heat exchanger to the energy storage device when the valve is in the second position.

Abstract: An evaporator unit comprising an evaporator, an internal heat exchanger defining a high pressure flow passage and a low pressure flow passage, an expansion device connected downstream of the high pressure flow passage of the internal heat exchanger and upstream of the evaporator. The internal heat exchanger is attached to the evaporator. With the above structure, the internal heat exchanger can utilize the remaining cooling capability of the refrigerant exiting from the evaporator for its greatest benefit.

Abstract: A climate control system may include a condenser, an evaporator, a compressor, a coolant circuit, and a heat exchanger. The evaporator may be in fluid communication with the condenser. The compressor may be in fluid communication with the condenser and the evaporator and may circulate a first fluid therebetween. The coolant circuit may include an engine, a radiator, and a second fluid circulating between the engine and the radiator. The heat exchanger may include a first fluid conduit and a second fluid conduit. The first fluid conduit may fluidly couple the compressor and the condenser. The second fluid conduit may fluidly couple the radiator and the engine. The heat exchanger may be configured to allow the second fluid to absorb heat from the first fluid.

Abstract: An air conditioner control method may entail measuring an evaporator first temperature at an exit side of the evaporator, maintaining the evaporator first temperature, measuring a length of time that the evaporator maintains the evaporator first temperature, providing a user-set evaporator target temperature; and reducing a rate of refrigerant compressed by a compressor based on a relationship between the length of time that the evaporator maintains the evaporator first temperature and the evaporator target temperature. Furthermore, an air conditioner control method utilizing a condenser and a cold storage unit may entail turning off an air conditioner compressor, maintaining operation of a condenser cooling fan, closing a thermostatic expansion valve, opening a bleed port to bypass the thermostatic expansion valve, and receiving a liquid refrigerant into the cold storage unit from the condenser after the refrigerant passes through a thermostatic expansion valve bleed port and the evaporator.
