WebLatent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing … Webthe heat pipes are driven by the heat pipe drive mechanism depending on the TES operation modes. In charge mode, the heat pipe condenser moves into the TES medium while the evaporator is exposed to an external system that supplies heat, enabling heat transfer from the external system to the TES medium. The opposite occurs in discharge mode.
