A drain assembly for a refrigeration appliance in communication with an appliance drain. The drain collects condensate from an evaporator behind the rear wall of the cabinet and transfers the condensate to the drain assembly in the machine compartment of the refrigeration appliance. The drain assembly then transfers the condensate to an extension tube easily accessible to an operator. The drain assembly includes an inlet, a main body, and an outlet. The inlet is secured to the appliance drain and the outlet is secured to the extension tube. The main body also comprises a downward slope in between the inlet and the outlet. In one example, a vacuum relief system can equalize a pressure differential between an interior of the main body and an exterior environment.

An insulated structure includes a wrapper that defines a first aperture. A liner defines a second aperture and is coupled to the wrapper. A negative pressure is maintained between the wrapper and the liner. A drainage assembly extends between the liner and the wrapper and is disposed within the first aperture and the second aperture. The drainage assembly includes a flexible body that has a plurality of flexures, first and second surfaces, and an opening that is defined between the first and second surfaces. The flexible body has at least one notch that is defined on the first surface that extends from a portion of the opening. A drainage tube extends through the opening that is defined by the flexible body and is operably coupled to the flexible body. The drainage tube includes at least one flange disposed within the at least one notch of the flexible body.

This invention is embodied in a system for removing moisture from the air inside a refrigerated space. The preferred embodiment is configured to work on a typical refrigerator that employs a typical refrigerant system with a compressor and a condenser. The preferred embodiment works by fitting a water jacket to the exterior surface of the refrigerant line. The water jacket is connected by flexible tube to a cold plate inside the refrigerator. Preferably a pump circulates fluid between the water jacket and the cold plate. As a result, the cold plate gets colder than the air inside the refrigerator and induces condensation on the cold plate. The condensation can be directed to flow by gravity down to the refrigerator's drip pan.

A household refrigeration apparatus includes an interior container with a first wall and a second wall angled thereto. The interior container bounds a first receiving space for food. An ice maker has a housing formed by wall areas of the first and second walls in certain areas. The housing bounds a receiving space of the ice maker. The housing has a wall unit separate from the interior container. The interior container has a rear wall having a base plate and a step integrally formed with the base plate. The wall unit has a wall element separate from the interior container. The wall element has an L-shape in cross-section, and the wall element has first and second wall plates together forming the L-shape. The first wall plate has a rear web resting on the step. A method for assembling an ice maker housing is also provided.

A refrigerator includes a storage space, an evaporator configured to cool air in the storage space based on heat exchange of a refrigerant, and a defroster configured to remove frost formed on the evaporator. The defroster incudes a pipe extended around the evaporator and including a circulation channel through which working fluid circulates, a fluid storage including a first opening and a second opening respectively communicating with opposite end portions of the pipe and configured to store the working fluid, and a pumping part disposed at a selected position on the circulation channel of the pipe between the evaporator and the fluid storage and configured to vaporize the working fluid to circulate the vaporized working fluid in the circulation channel.

A heating, ventilation, and/or air conditioning (HVAC) unit includes a drain pan configured to collect condensate generated by the HVAC unit. The HVAC unit also includes a drain spout having a rigid outlet port coupled to the drain pan and a flexible conduit coupled to the rigid outlet port. The drain spout is adjustable between a first configuration configured to discharge the condensate from the HVAC unit via a first opening of the HVAC unit and a second configuration configured to discharge the condensate from the HVAC unit via a second opening of the HVAC unit.

The present disclosure relates to a heat exchanger for a heating, ventilating, and air conditioning (HVAC) system that includes a first slab having a first plurality of tubes extending between a first manifold and a second manifold and a second slab having a second plurality of tubes and a third plurality of tubes. The second plurality of tubes extends between a third manifold and a fourth manifold and the third plurality of tubes extends between the fourth manifold and a fifth manifold, such that the heat exchanger defines a refrigerant path sequentially through the first plurality of tubes, the second plurality of tubes, and the third plurality of tubes.

A refrigerator includes: a cabinet including an inner case provided with a storage compartment, a case supporter coupled to a lower side of the inner case to support the inner case, and a base coupled to a lower side of the case supporter; a door disposed on a front portion of the cabinet to open and close the storage compartment; and a cooling device disposed on a rear surface of the inner case to have at least a portion thereof exposed to the storage compartment, wherein a water collection hole is formed on a rear end of a bottom surface of the inner case, wherein a water collection guide is mounted on the inner case to guide water flowing into the water collection hole to flow downward, wherein a water collection portion is formed on the base to collect water passing through the water collection guide.

In a configuration in which a CA system adjusts the composition of air in an internal space of a storeroom, a concentration sensor, such as an oxygen sensor or a carbon dioxide sensor, is disposed outside the storeroom, and a concentration detection air passage is provided between the internal space and the concentration sensor.
