Abstract: An ultra low temperature freezer evaporator (ULT) apparatus that has a triple feed capillary tube system. The ULT apparatus prevents the low stage compressor from running in a vacuum. The invention significantly reduces the “pull down” time. Further, the ULT freezer evaporator apparatus significantly increases the transfer area between the evaporator tubing and the contact surface on the unit to assist the transfer of heat from the refrigerated unit through the condenser to the surrounding room.

Abstract: An environmentally controlled chamber system. The system includes an insulated enclosure having an access door and a humidification/dehumidification chamber enclosure arranged and disposed to provide humidification or dehumidification to the insulated enclosure. The system also includes a refrigerant loop having an enclosure evaporator, a dehumidification evaporator, at least one condenser, a variable speed compressor and piping for directing refrigerant from the variable speed compressor to the enclosure evaporator, the dehumidification evaporator, and the at least one condenser. An electrical heating element is arranged and disposed adjacent to the enclosure evaporator to selectively provide heat to at least a portion of the enclosure evaporator. A method for controlling the environmentally controlled chamber system is also disclosed.
