ABSTRACT:
A non-frosting heat absorption system is disclosed for temperature stabilizing the heat absorbing surfaces thereof and includes a heat absorption arrangement such as a refrigeration system evaporator coil having a first series of heat exchange surfaces in good heat transfer relation therewith. A second series of heat exchange surfaces have portions thereof in good heat transfer relationship with a heat load such as air circulated thereby and other portions thereof immersed in and coupled to the first series of heat exchange surfaces by a heat storage arrangement including a phase change material such as water. The phase change material then permits the transfer of heat from the second series of surfaces to the first series of surfaces while allowing the second series of surfaces to be maintained near the phase change temperature of the material during various heat load conditions. The phase change material forms the sole heat transferring connection between the two series of surfaces and therefore assures that the air exposed series of surfaces do not frost until a substantial quantity of the phase change material has first been solidified.
