Abstract: A refrigeration door system has a defrosting feature. The refrigeration door system also includes a housing defining a refrigerated cavity therein, and a door assembly carried by the housing and providing access to the refrigerated cavity. The door assembly includes a door frame and door coupled to the door frame. The door switches between an open position providing the access to the refrigerated cavity and a closed position where the refrigerated cavity is inaccessible. The door frame includes gasket pieces carried by a first side member and a second side member. The gasket pieces are spaced apart and define an air channel. The refrigeration door system also includes a positive pressure source fluidly coupled to the top member and configured to output air, and a heating device configured to heat the air from the positive pressure source.

Abstract: In an air-conditioning apparatus, a first flow passage selection device and a second flow passage selection device each are a constant-energized-type three-way valve in which a position of a main valve can be fixed in a de-energized state. When the refrigerant circuit is switched to the cooling circuit by a flow switching device, when at least one of the first flow passage selection device and the second flow passage selection device is in a de-energized state, the first flow passage selection device or the second flow passage selection device in the de-energized state is configured to output refrigerant discharged from the compressor and input therein via the flow switching device and the bypass pipe to a corresponding one of an upper-side outdoor heat exchanger and a lower-side outdoor heat exchanger.

Abstract: A heat exchanger module includes a skin condenser and a skin evaporator. The skin condenser includes an inner condenser plate, an outer condenser plate coupled to the inner condenser plate and a condenser tube channel formed on one of the inner condenser plate and/or the outer condenser plate. The evaporator includes an inner evaporator plate, an outer evaporator plate coupled to the inner evaporator plate, and an evaporator tube channel formed on one of the inner evaporator plate and/or the outer evaporator plate. The heat exchanger also includes an insulation layer extending between the inner condenser plate and the inner evaporator plate. Each of the plates that form the skin condenser and/or evaporator can be formed from different materials and/or have different material thicknesses to reduce heat transfer through the insulation layer from the condenser to the evaporator while also promoting heat transfer through natural convection with surrounding air.
