Thermal expansion valve - Wikipedia

In practice, the Joule–Thomson effect is achieved by allowing the gas to expand through a throttling device (usually a valve) which must be very well insulated to prevent any heat transfer to or from the gas. No external work is extracted from the gas during the expansion (the gas must not be expanded through a turbine, for example). The cooling produced in the Joule–Thomson expansion makes it a valuable tool in refrigeration. … WebMay 22, 2024 · Expansion valve (also called a throttle valve) Evaporator In an ideal vapor-compression cycle, the system executing the cycle undergoes a series of four processes: one isentropic (reversible … my city after school freeWebThe main problem for the reduction in efficiency of the refrigeration cycle is the expansion or throttling process in the expansion valve. It reduces cooling capacity as well as increase the power input. In the case of the expansion process in the expansion valve, some amount of refrigerant vapor is generated due to low pressure. office depot voucher
