Abstract
A method of enhancing the defrost and heating cycles of a transport refrigeration system for a straight truck, which refrigeration system includes a single refrigeration circuit selectively connectible to a compressor driven by the truck engine, or to a stand-by compressor driven by a motor connected to a stand-by source of electrical potential. The enhancement is achieved by slowly but continuously storing heat in an accumulator from the truck electrical system, or from the stand-by source of electrical potential, such that liquified refrigerant introduced into the accumulator during a defrost or heating cycle is immmediately vaporized. The slow but continuous rate of heat storage accumulates the requisite heat without unduly loading the truck electrical system or the truck engine.
