  • Heat exchanger with heater insert
    Patent number: 10935329
    Abstract: A heat exchanger includes fins that are spaced apart from each other, and that each include one or more tube slots. A coil is coupled to the fins and includes a tube section extending through axially aligned tube slots. A heater insert extends through one or more of the axially aligned tube slots adjacent an exterior of the tube section to defrost the heat exchanger.

  • REFRIGERATION SYSTEM WITH FLUID DEFROST
    Publication number: 20170292770
    Abstract: A refrigeration system having a refrigerant circuit including a condenser, a flow control device, an evaporator, and a compressor connected in series. The compressor is configured to circulate a cooling fluid through the refrigerant circuit. The refrigerant circuit has an inlet line fluidly connecting the condenser to the evaporator and a suction line fluidly connecting the evaporator to the compressor. A heater is positioned to heat the cooling fluid during a defrost mode, and a pressure control is coupled to the refrigerant circuit downstream of the evaporator. In the defrost mode, the pressure control apparatus is configured to increase system pressure during the defrost mode to maintain flow of refrigerant into the evaporator and to control flow of cooling fluid to the compressor.
