Refrigeration by throttling of gas
Did you know?
WebA refrigerator with a single compressor can provide refrigeration at several temperatures by throttling the refrigerant in stages. Liquefaction of gases Another way of improving the performance of a vapor-compression refrigeration system is by using multistage compression with regenerative cooling. Webbecause of the ideal gas behavior of the refrigerant, the enthalpy of the gas is only a function of the temperature of the gas, and since the throttling is an isenthalpic process, …
WebDec 11, 2024 · The throttling device is composed of a capillary tube which has a diameter of roughly 0.6 mm and a length of 2 m. High pressured liquid enters the throttling device. The throttling device will act as an obstruction to the flow of the high-pressured liquid and will result in a pressure drop. WebThe operating conditions of the ejector applied in compressor refrigeration systems as device for reduction of the throttling losses are determined with the refrigeration system …
