    摘要： A cooling system is disclosed so that an operator cabin can be cooled even if the engine is off. An accumulator can be used to store high-pressure refrigerant until its release. When the compressor is off, the accumulator can release the high pressure refrigerant through the pressure reducer and to the evaporator where heat in the operator cabin can be removed by the refrigerant. An absorption bed with activated carbon can be used to adsorb the refrigerant from the evaporator in order to create a pressure gradient in A/C system. The refrigerant in the accumulator can also be used to subcool a refrigerant in the condenser through a heat exchanger. This allows the operator cabin to be cooled faster up on engine start up. The adsorption bed can also be used to create a pressure gradient in the cooling system.

    摘要： A decentralized condenser evaporator system includes (i) a condenser system positioned to receive a gaseous refrigerant from a centralized compressor system and configured to condense the gaseous refrigerant into a liquid refrigerant, (ii) a controlled pressure receiver positioned to receive and store the liquid refrigerant, (iii) an evaporator system including a conduit, an expansion valve, and a fan, and (iv) a controller. The conduit is positioned to receive the liquid refrigerant from the controlled pressure receiver. The expansion device is positioned between the controlled pressure receiver and the conduit, and configured to facilitate modulating an amount of the liquid refrigerant that flows into the conduit from the controlled pressure receiver. The fan is positioned to facilitate providing a cooling operation to an area associated with the evaporator system through evaporation of the liquid refrigerant flowing through the conduit. The controller is configured to control a stage of the condenser system and/or the evaporator system to maintain a desired level of the liquid refrigerant within the controlled pressure receiver and facilitate maintaining a system condensing pressure of the refrigeration system at a target system condensing pressure.

    摘要： A variable refrigerant charge refrigeration/air conditioner system is described that allows the refrigerant charge for the system to be altered based on operating or environmental factors. The system includes a main refrigerant loop holding a volume of refrigerant corresponding to a first level of refrigerant charge, a compressor in the main refrigerant loop, a condenser in the main refrigerant loop, and an evaporator in the main refrigerant loop. A branch refrigerant loop allows the alteration of the refrigerant charge using a control valve in the branch refrigerant loop and a receiver in the branch refrigerant loop. The receiver acts to hold a volume of refrigerant when the control valve is open, thereby removing the volume of refrigerant from the main refrigerant loop. A return path from the receiver to the main refrigerant loop allows refrigerant to flow back into the main loop from the receiver.

    摘要： A vapor compression system that circulates a fluid through a closed loop interconnecting a compressor, a first heat exchanger, a flow-restricting expansion device, and a second heat exchanger. The system further includes a vessel in a first fluid communication and a selective second fluid communication with the loop between the compressor and the first heat exchanger with each of the first and second fluid communication configured to receive fluid from the loop. The vessel is in a third fluid communication with the first heat exchanger configured to provide fluid to the first heat exchanger. In response to a predetermined ambient temperature surrounding the system, the second fluid communication is selectively opened to provide an increased fluid flow from the vessel to the first heat exchanger.
