ABSTRACT:
In a refrigeration system including a refrigerating coil, for circulating refrigerant to cool the space ambient thereto, and a defrost pan beneath the coil having a liquid drain outlet so that ice formed thereon by water condensing from the space drops therefrom to the pan, the improvement which comprises a heater pad mounted in the defrost pan to receive ice dropping from the coil, the heater pad comprising a generally flat array of laterally spaced elongated members of good heat conductivity having flat lower surfaces in contact with the defrost pan and flat upper surfaces jointly defining a longitudinally slotted substantially continuous ice receiving plane, the surfaces being in heat conductive relation with central fluid conducting bores, and the pad further comprising conduits for conducting heated fluid to and from the bores in a desired flow pattern to supply heat for conduction to the surfaces.
