摘要： A method for controlling a vapour compression system (1) is disclosed. The vapour compression system (1) comprises an ejector (6) and a liquid separating device (10) arranged in a suction line. At least one evaporator (9) is allowed to be operated in a flooded state. A flow rate of refrigerant from the liquid separating device (10) to the secondary inlet (15) of the ejector (6) is detected, and it is determined whether or not the flow rate is sufficient to remove liquid refrigerant produced by the evaporator(s) (9) being allowed to be operated in a flooded state from the liquid separating device (10). In the case that it is determined that the flow rate of refrigerant from the liquid separating device (10) to the secondary inlet (15) of the ejector (6) is insufficient to remove liquid refrigerant produced by the evaporator(s) (9), the flow rate of refrigerant from the liquid separating device (10) to the secondary inlet (15) of the ejector (6) is increased, and/or a flow rate of liquid refrigerant from the evaporator(s) (9) to the liquid separating device (10) is decreased.

摘要： Systems and methods relating to a plural in-series pumped liquid refrigerant trim evaporator cycle are described. The cooling systems include a first evaporator coil in thermal communication with an air intake flow to a heat load, and a first liquid refrigerant distribution unit in thermal communication with the first evaporator coil. The cooling systems further include a second evaporator coil disposed in series with the first evaporator coil in the air intake flow and in thermal communication with the air intake flow, and a second liquid refrigerant distribution unit in thermal communication with the second evaporator coil. A trim compression cycle of the second liquid refrigerant distribution unit is configured to further cool the air intake flow through the second evaporator coil when the temperature of the first fluid flowing out of the main compressor of the second liquid refrigerant distribution unit exceeds a predetermined threshold temperature.

摘要： A system for conditioning air circulated from an interior of a building includes a refrigerant path, an air-cooled condenser in the refrigerant path, a water-cooled condenser in the refrigerant path that transfers heat from refrigerant in the refrigerant path to the building water, an evaporator in the refrigerant path, and a control system. The control system moves the system between operation of the air-cooled condenser and the water-cooled condenser based upon predetermined system conditions.

摘要： A cascade heat recovery system connects an evaporator from a heating unit to a recovery condenser of the cooling unit, where the recovery condenser is different from a cooling condenser of the cooling unit, and/or connects the evaporator of the heating unit to the cooling loop of the cooling unit, for example in fluid communication with the evaporator of the cooling unit. Both configurations allow the heating unit to be isolated or decoupled from the heat rejection circuit on which the cooling condenser runs. The use of either or both configurations, depending on the operating conditions, can use heat rejected by the evaporator of the cooling unit to be available to the heating unit, so as to provide lift to the heating unit and improve its operating efficiency.

摘要： In an ejector, a passage formation member is disposed inside a body forming a space therein. Provided between an inner peripheral surface of the body and the passage formation member are a nozzle passage functioning as a nozzle, a mixing passage in which an ejection refrigerant ejected from the nozzle passage and a suction refrigerant drawn through a suction passage are mixed together, and a diffuser passage that converts a kinetic energy of the refrigerant that has flowed out of the mixing passage into a pressure energy. The mixing passage has a shape gradually reducing in cross-sectional area toward a downstream side in the refrigerant flow.

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： Energy systems in different industrial applications including automotive applications experience between 20 to 50 percent of raw energy input as waste heat. in the form of hot exhaust gases, hot cooling water and lost heat from hot equipment surfaces including heated products. Continued efforts to improve systems energy efficiency, recovering waste heat losses provide attractive opportunities for reduced emission and less costly energy resources. This invention introduces other methods for higher performance of existing energy consuming systems by optimizing the performance of some of the system modules that contributes to the waste energy. in turn reduce energy consumption of these systems, reduces its operating cost, damages to the population health by reducing pollution improving the environment quality, and also reduces the cost of health care. Improving efficiency of the module's' which contribute large percentage of waste energy as by-product from the operation of these systems can improve the system efficiency.

摘要： A system for cooling air for use with a liquid cooling fluid loop. The system includes a first refrigerant circuit with an air-cooled condenser, a second refrigerant circuit with a liquid-cooled condenser, and a free-cooling loop. A control device is provided for controlling the operation of the system between a first mode, a second mode, and a third mode. When operating in the first mode, only the free-cooling loop cooperates directly with liquid cooling fluid in the liquid cooling fluid loop to cool the liquid cooling fluid, when operating in the second mode, the second refrigerant circuit is not engaged, and when operating in the third mode, the free-cooling loop interacts with the second refrigerant circuit to reject heat of the second refrigerant circuit through the free-cooling loop.
