  • Defrost system for a refrigeration device
    Publication number: 20060242982
    Abstract: A defrost system for a temperature controlled storage unit includes an enclosure providing a space for storage of products. A refrigeration system has a supply line and a return line coupled to a cooling element to circulate a refrigerant through the cooling element to provide cooling to the space. A control module initiates a plurality of defrost modes on a predetermined frequency and for a predetermined duration by reducing a flow rate of the refrigerant through the cooling element so that a superheat temperature of the refrigerant in the cooling coil is increased to a predetermined range.
