Isenthalpic expansion is a thermodynamic process where a substance expands at constant enthalpy, meaning there is no heat exchange with the surroundings. This process is typically associated with the throttling of fluids, such as in refrigeration and air conditioning systems, where a refrigerant undergoes a rapid drop in pressure without any heat transfer, leading to a temperature decrease. This expansion is crucial in understanding how cooling systems operate efficiently while managing energy transfers.
