A drainage system comprising a first bracket having a horizontal structure and one or more vertical structures, a second bracket having a horizontal structure and one or more vertical structures and a drain pan having a plurality of locking mechanisms, each configured to interlock with one of the vertical structures of the first bracket or the second bracket.

An adjustable liquid containment device for use with refrigerators to prevent overflow and damage to flooring. The containment device allows for appliance elevation within an integral support and water collection pan. The detachable loading ramps provide for smoothly rolling the appliance up onto the integrated independent elevated level support surfaces within the water retainment pan. The containment device is telescopically adjustable to accommodate different size appliances.

A refrigerator includes a first storage chamber, a second storage chamber, and a heat exchange chamber therebetween. At least one first inlet is configured to introduce cold air from the first storage chamber into the heat exchange chamber, and at least one second inlet is configured to introduce cold air from the second storage chamber into the heat exchange chamber. The first and second inlets are provided at sides of the refrigerator.

A refrigerator includes a heat exchange chamber, first inlets arranged on side surfaces of a first storage chamber and configured to introduce cold air in the first storage chamber into the heat exchange chamber, and second inlets arranged on side surfaces of a second storage chamber and configured to introduce cold air in the second storage chamber into the heat exchange chamber.

A refrigerator includes an evaporator inclined in a left-right direction and a defrosting water tray provided below the evaporator to collect defrosting water, and having inclined surfaces corresponding to a shape of the evaporator.

A defrost heat discharge system includes a drain duct configured to discharge heat from a defrost heater and to discharge condensed water that results from melting of frost on an evaporator by heat generated by the defrost heater, a drain pipe that connects a first space to a second space, that is configured to allow condensed water to flow from the first space to the second space, and that is configured to discharge heat generated by the defrost heater from the first space to the second space, a drain cap located at an end of the drain pipe and configured to open and close at least a portion of the drain pipe; and a condensing fan configured to receive heat from the defrost heater and discharge heat toward an outside of the second space based on the drain cap opening the portion of the drain pipe.

Arrangement for accumulation and evacuation of water such as defrosting and condensation water from refrigeration units, the system including a piping arrangement with a vertical pipe section extending from a water evacuation unit provided in conjunction with the respective refrigeration unit; discharge valves, one for each unit; one or more liquid reservoir for each unit; one or more vacuum pumps; air inlet nozzles; a control unit; one or more level switches and air conduit inlet opening for each vertical pipe. Each of the water evacuation units includes a docking station and a water collection tray preferably to be slideably provided within the docking station, whereby each unit is custom made to fit between the refrigeration unit and floor where the refrigeration units are placed.

A refrigerator includes a heat exchange chamber, first inlets arranged on side surfaces of a first storage chamber and configured to introduce cold air in the first storage chamber into the heat exchange chamber, and second inlets arranged on side surfaces of a second storage chamber and configured to introduce cold air in the second storage chamber into the heat exchange chamber.

In one instance, a cooling unit for use as an aspect of a cooling system includes a cabinet having a plurality of panels and having an interior, a front face with a fan aperture formed in the front face, and a bottom panel. The cooling unit further includes a drain pan below the bottom panel. The cooling unit also includes a plurality of guide-rail slide and track assemblies coupled between at least a portion of the cabinet and the drain pan for providing controlled movement of the drain pan between an operational position and a maintenance position. Other cooling units are disclosed with drain pans that may be lowered by a single technician.
