The separator has a distributor tube which extends in the inlet chamber in the evaporator transverse direction.

An ice maker evaporator assembly having an evaporator pan with a back wall and left, right, top and bottom sidewalls extending from the back wall, and a freeze plate located within the evaporator pan. A serpentine tubing is thermally coupled to the back wall of the evaporator pan opposite the left, right, top and bottom sidewalls. A first layer of insulation is formed on the serpentine tubing. An evaporator housing having a housing back wall and housing left, right, top and bottom sidewalls extending from the housing back wall is attached to the evaporator pan and covers serpentine tubing. A second layer of insulation is formed on top of the first layer of insulation.

A heat exchanger includes a cylindrical stator and a cylindrical rotor that are spaced by a cylindrical gap. The cylindrical rotor is configured to rotate relative to the cylindrical stator about a rotation axis. A flattened tube is positioned within the cylindrical gap and is wrapped on the cylindrical stator. The flattened tube is spaced from a surface of the cylindrical rotor that faces the cylindrical gap.

A heat exchanger includes a plurality of principal heat exchange sections and auxiliary heat exchange sections. Each of the auxiliary heat exchange sections is in series connection to a corresponding one of the principal heat exchange sections. Tube number ratios of the principal heat exchange sections are obtained by dividing the number of the flat tubes constituting each of the principal heat exchange sections to by the number of the flat tubes constituting a corresponding one of the auxiliary heat exchange sections. Of the principal heat exchange sections, the first principal heat exchange section, which is the lowermost one, has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section is accelerated during defrosting, thereby shortening the time required for defrosting.

An air conditioning system includes evaporative cooling units, each evaporative cooling unit including a first V-shaped portion of a winding of microporous hollow fibers that are configured to receive a liquid, and a second V-shaped portion of the winding of microporous hollow fibers that are configured to receive the liquid, where the second V-shaped portion is coupled to the first V-shaped portion, and an internal cavity is disposed between the first V-shaped portion and the second V-shaped portion. The air conditioning system also includes a plumbing assembly configured to supply the liquid to the plurality of evaporative cooling units. The air conditioning system also includes a controller configured to control the plumbing assembly to change a flow rate of the liquid, or to block the liquid from at least one evaporative cooling unit of the plurality of evaporative cooling units.

A refrigeration appliance has a refrigeration appliance component and a cleaning device for cleaning the component. The cleaning device includes a cleaning element, an actuating element, and a connection element. The cleaning element is connected to the actuating element by the connection element. The refrigeration appliance has a cavity which extends from the front side of the refrigeration appliance to the back side of the refrigeration appliance, and in which the connection element is accommodated. The cleaning element is moveable across a surface of the refrigeration appliance component upon actuation of the actuating element in order to remove dirt deposits from the surface of the refrigeration appliance component.

An evaporator includes a refrigerant conduit; and front and rear plates sandwiching the refrigerant conduit, each of the front and rear plates including: a plurality of ice forming columns; a set of first protrusions and a set of second protrusions defined therein, each first protrusion on the front plate and a corresponding first protrusion on the rear plate defining a respective active cavity and each second protrusion on the front plate and a corresponding second protrusion on the rear plate defining a respective passive cavity, the refrigerant conduit extending through each of the active cavities but not any of the passive cavities; and inner flat portions of the front plate and the rear plate facing each other to define respective spaced portions, wherein the active cavities and passive cavities are interspersed and separated by respective inner flat portions so as to define a plurality of ice forming sites.

Disclosed is a plate heat exchanger with an inlet flow regulating structure (11), comprising a refrigerant inlet coupling (4), a side plate (1) assembled with the refrigerant inlet coupling (4), and at least one inlet flow regulating structure (11). The inlet flow regulating structure (11) is arranged on a path from the refrigerant inlet coupling (4) to a main body of the plate heat exchanger, and is provided with at least one flow regulating element (12, 13, 14, 15) which is provided corresponding to a refrigerant inlet passage of the plate heat exchanger.
