WebFeb 2, 2011 · A refrigerator is a device which is designed to remove heat from a space that is at lower temperature than its surroundings. The same device can be used to heat a volume that is at higher temperature than the surroundings. In this case the device is called a Heat Pump. The distinction between a refrigerator and a heat pump is one of purpose ... WebAdiabatic cooling is a type of thermodynamic process in which the temperature of the working fluid reduces without any transfer of heat between system and surroundings. This happens when pressure of the system reduces and volume expands. The walls of system are adiabatic so they do not let heat escape or enter the system.

WebJoule Thomson Effect Definition. When a real gas is subjected to adiabatic expansion process, where no heat is exchanged with the surroundings, it looses its temperature. This cooling effect of gas expansion is known as the 'Joule Thomsone effect'. This is even applicable to real gases when the Z factor or compressibility factor is used. So ... WebIt is usually expressed as a fractional change in length or volume per unit temperature change; a linear expansion coefficient is usually employed in describing the expansion of a solid, while a volume expansion coefficient is more useful for a liquid or a gas.

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. …
