Experiments were conducted to measure the temperatures of a reversing valve and to provide the necessary data for calculating the reversing valve heat loss under free convection. These calculations were done by a control-volume analysis and a surface heat-transfer analysis to determine the important paths of heat transfer. For the particular valve analyzed, the major paths are through conduction. Radiant and convective losses are relatively insignificant. The importance of including the tubing attached to the valve in the analysis is underscored.
