Related to latent heat:Latent heat of fusion,Latent heat of vaporization latent heat n. The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Also calledheat of transformatio...
the heated fluid moves along the adiabatic section to the condenser and then condenses at that section and releases the latent heat of vaporization to the heat sink. The capillary effect assists the working flow going back to the evaporator. This capillary effect can be improved by wicks in ...
