A refrigerator includes a vacuum insulated cabinet structure having side walls that are formed from a tube that has been folded/deformed into a structure having an “O” shape with vertically enlarged front and rear openings. The interior of the tube may be filled with silica powder or other filler, and a vacuum is formed within the tube. An insulated rear panel may be utilized to close off the rear opening of the vacuum insulated cabinet structure.

A cooling member includes a heat-transfer member, a refrigerant introducing pipe and a covering material. The heat-transfer member has a surface with a groove opened to the surface of the heat-transfer member. The refrigerant introducing pipe is pressed into the groove. The covering material coats the surface of the heat-transfer member and the refrigerant introducing pipe.

A method of forming a refrigeration heat exchanger comprising a suction line and a capillary line includes juxtaposing at least a portion of the suction and capillary lines to form a juxtaposed portion, at least partially enveloping the juxtaposed portion with a metal material, and encapsulating the capillary line to the suction line along at least a portion of the juxtaposed portion.

A refrigeration system includes a supplemental heat exchanger operably disposed between a condenser and an evaporator. This supplemental heat exchanger is located in selective fluid communication with the air in the conditioned space, and can be toggled between an “invisible” mode in which the heat exchanger acts as a simple fluid conduit between the condenser and evaporator, and a “humidity reduction” mode in which the heat exchanger operates to transfer heat from hot refrigerant to the colder conditioned space. This addition of heat into the conditioned space decreases the relative humidity of the conditioned space and subcools the refrigerant leading to the expansion valve and evaporator. This subcooling of the liquid enables the evaporator to operate at a lower temperature which enhances the moisture removal from the air moving through the evaporator. The supplemental heat exchanger may be located in a physically elevated position relative to the remainder of the conditioned space to utilize stratification of hot air to create a default “invisible mode” without inducing airflow.

A refrigerated sales cabinet (20a) includes a cabinet body (22a) providing a refrigerated sales space for supporting refrigerated goods to be presented therein; a door frame (21a) having a top post (34a), a bottom post (36a), and at least two upright posts (32a); wherein at least one of the posts (32a, 34a, 36a) comprises an air duct allowing to conduct air through the post (32a, 34a, 36a), and wherein at least one fan (18) is fluidly connected to the air duct in order to convey ambient air through the air duct.

A refrigerator in which an ice making chamber case including a horizontal wall, a vertical wall, a front opening and a front edge is coupled to an inside of an inner case, to form an ice making chamber. A case insulator is disposed in a wall space of the ice making chamber case. The case insulator is foamed separately from a body insulator which is foamed between inner and outer cases of a refrigerator body. Since the case insulator is foamed separately from the body insulator, it is possible to easily achieve foaming of the case insulator. It is also possible to prepare the ice making chamber case separately from molding of the inner case.

One aspect of this disclosure provides a packaged air conditioning & heating (PACH) system that comprises a housing, an air cooling system contained within the housing and an air heating system contained within the housing. A first utility access point is located on a first side of the housing and a second utility access point is located on a second side of the housing. The first and second utility access points provide multiple utility access connectivity for the air cooling and heating systems.

In a method for the production of a cooling plate from a material having thermal conductivity, a workpiece in the form of a flat material blank with uniform material thickness is placed into a tool. The workpiece is pressed in a first stage by an inner punch of the tool to form in cooperation with pin forming openings of the tool pins upon an effective surface swept by the coolant, as the workpiece is held down by an outer punch of the tool, such that the pins protrude approximately perpendicular over a base area of the workpiece. In a second stage, the workpiece is pressed by the outer punch such as to form an essentially radially extending, flat peripheral edge of reduced material thickness in surrounding relation to the pins, as the workpiece with the formed pins is held down by the inner punch of the tool.

A controller, a water source heat pump and a computer useable medium are disclosed herein. In one embodiment the controller includes: (1) an interface configured to receive operating data and monitoring data from the water source heat pump and transmit control signals to components of thereof and (2) a processor configured to respond to the operating data or the monitoring data by operating at least one motor-operated valve of the water source heat pump via a control signal.

An air-conditioning cabinet can have an outer chamber, an inner chamber with an inner chamber height, a cover, a bottom where the cover and bottom are separated by a distance that defines the inner chamber height, an inner chamber having a foot movably coupled to the inner chamber, where the inner chamber is arranged in the outer chamber, where the inner chamber height is less than the inner chamber height and where the foot is movably coupled to the inner chamber in such a manner that the inner chamber height is variable. Also, moving a position of the foot on the inner chamber can arrange the inner chamber such that the inner chamber is supported on the cover of the outer chamber and the foot is supported on the bottom of the outer chamber, and the foot can be fixed in the position.
