The present disclosure generally relates to a temperature-controlled displays and refrigeration systems for temperature-controlled displays. For instance, in one implementation a temperature-controlled display includes a multi-loop refrigeration system with reclaim heating and a condensation control system. The refrigeration system includes a refrigeration loop and a cooling loop in thermal communication with the refrigeration loop. The refrigeration loop is configured to refrigerate the temperature-controlled display. The cooling loop is configured to remove heat from the refrigeration loop and provide the heat removed from the refrigeration loop as reclaim heat. The condensation control system includes a heat exchanger in thermal communication with the cooling loop. The heat exchanger is configured to transfer the reclaim heat from the cooling loop to a flow of air directed over a transparent surface of the temperature-controlled display.

A fan plenum assembly for a merchandiser. The fan plenum assembly includes a plenum housing that defines an opening configured to receive a fan, and that has a side wall with a slot and a slot extension continuous with the slot. The slot has a major axis extending through a center of the slot. A bearing is configured to rotationally support a hinge pin and is coupled to the side wall. The bearing includes a positioning element that is disposed in the slot and in the slot extension. The positioning element is movable within the slot and the slot extension such that the bearing is movable along the major axis to permit axial adjustment of a position of the bearing relative to the plenum housing and the bearing is immovable rotationally relative to the plenum housing.

A refrigerated display case comprising framework having four sides, each side including a C-shaped frame with a rear vertical side strut, a top side strut, and a bottom side strut; the C-shaped side frames are constructed separately and support cover panels of a bottom assembly, a rear wall assembly, and a top assembly, the cover panels being fastened by mounting elements and delimit a cooling chamber, the cooling chamber including at least one C-shaped intermediate frame between the C-shaped side frames, the at least one C-shaped intermediate frame is spaced laterally apart from the C-shaped side frames, the C-shaped intermediate frames each include a horizontal bottom intermediate strut, a vertical intermediate strut and a top intermediate strut.

The present invention relates to a display cabinet (1) having an open face; an air circulation system comprising: an air inlet (9) located adjacent to a perimeter of the open front face; an air outlet (7) located adjacent to the perimeter of the open front face opposite the air inlet (9), and configured to blow air across the open front face toward the air inlet (9); an air conduit (11, 17) for conveying air from the air inlet (9) to the air outlet (7); and an air pump configured to draw air from the air inlet (9), move the air thus drawn through the air conduit (11, 17) to the air outlet (7); and at least one shelf (3) disposed within the display cabinet (1); wherein the air conduit (11, 17) is arranged such that at least a portion (19) of the air from the air inlet (9) follows a path that passes out from a wall of the display cabinet (1) through the at least one shelf (3), and back through said at least one shelf (3) to the wall of the display cabinet (1), before being passed to the air outlet (7).

An open display refrigerator comprises a refrigerated interior space, air in the refrigerated interior space being separated from air exterior to the open display refrigerator by an air curtain established by a fan which blows air through an air outlet towards a corresponding air inlet which recovers air from the air curtain for recirculation to the air outlet. A distal region of the air outlet is occluded to leave only a region of the air outlet proximal to the interior space open, and an air curtain guide is aligned in a direction of air flow of the air curtain with an edge of the blanking plate proximal to the interior space.

Display cases may include deflectors and fans. The deflectors may alter air currents generated by fans to provide an air current to display portions of the display case. In some implementations, the altered air current may have a first portion with a velocity that is greater than a velocity of a second portion, where the first portion is closer to a display portion of the display case.

A refrigerated sales furniture (2) comprises a base (4) provided at the bottom of the refrigerated sales furniture (2); a goods presentation space (10) comprising a front portion allowing access to the goods presentation space (10) and an opposing rear portion; wherein the goods presentation space (10) includes a bottom area (12) located next to the base (4); and a cold air channel (48) located next to the rear portion of the goods presentation space (10) comprising a lower portion (54) arranged next to the bottom area (12) of the goods presentation space (10) and having an opening (18) fluidly connecting the cold air channel (48) with the bottom area (12) of the goods presentation space (10) for allowing cold air to flow from the lower portion (54) of the cold air channel (48) into the bottom area (12) of the goods presentation space (10). The opening (18) is provided as a single opening (18) extending substantially over the whole height and width of the bottom area (12), respectively.

An axial flow fan includes a generally hollow casing defining an inlet end and an outlet end of the axial flow fan. A diameter of the casing increases from the inlet end to the outlet end. An impeller is rotatably mounted within the casing. The impeller includes a hub and a plurality of fan blades extending from a root located at the hub to a blade tip. A diameter of the blade tip of each of the plurality of fan blades increases from the inlet end to the outlet end. A tip fence is located at the blade tip of at least one of the plurality of fan blades and a length of the tip fence measured perpendicular to the fan blades is greater than a thickness of the at least one of the plurality of fan blades.

A temperature controlled case includes a housing that defines a temperature controlled space and a multi-circuit cooling element in thermal communication with the temperature controlled space. The multi-circuit cooling element includes two or more cooling coils. Each of the cooling coils is coupled to a different circuit structured to selectively circulate coolant through the multi-circuit cooling element. Each circuit is fluidly separate from each remaining circuit such that the coolant circulated through each circuit is not shared with each remaining circuit. The multi-circuit cooling element further includes a plurality of heat exchange fins coupled to each of the two or more cooling coils such that each of the heat exchange fins facilitates heat removal from the temperature controlled space by each of the two or more cooling coils.

A refrigerated merchandiser including a case defining a product display area supporting product and an evaporator disposed in an air passageway in fluid communication with the product display area via an outlet to direct a refrigerated airflow into the product display area. The merchandiser also includes a control system in communication with and programmed to control the refrigeration system so that the product display area is maintained within a predetermined temperature range. The control system also varies the temperature of the refrigerated airflow through the outlet above an airflow temperature threshold between about 35 degrees Fahrenheit and 41 degrees Fahrenheit at least once during a predetermined time period to avoid formation of frost on the evaporator while maintaining the product display area within the predetermined temperature range.
