Refrigerated display case and night cover therefor
A refrigerated display case 1 of the open front type has a roller mounted night cover 51 formed of flexible material which, in a deployed position, is arranged to close the front opening of the display case. The flexible material of the night cover has a plurality of apertures 54 arranged in a first section 51 that are disposed in an upper 30%-40% of the front opening. The apertures have a constant diameter D, chosen to be a fixed dimension in the range 9 mm-11 mm, that are arranged in a vertical and a horizontal grid. The spacing between the aperture centres in the vertical direction y of the grid is 3D and the spacing between aperture centres in the horizontal direction x of the grid is in the range 2D to 4D, preferably 3D. The specific dimensions of the first section and of the apertures and their grid arrangement is arranged to eliminate hotspots and improve the efficiency of the refrigeration system.
REFRIGERATED DISPLAY CABINET UTILIZING A RADIAL CROSS FLOW FAN
A refrigerated display case includes a housing surrounding multiple shelves. An air distribution gap is defined behind the shelves. An air return passage is defined below the shelves. A radial cross-flow fan is disposed in a fan region of the air return passage. The radial cross-flow fan includes an output connected to the air distribution gap. A primary cooling microchannel heat exchanger is disposed in the fan region downstream of the radial cross-flow fan such that air output from the radial cross-flow fan to the air distribution gap passes through the primary cooling microchannel heat exchanger. A pre-cooler microchannel heat exchanger is disposed upstream of the primary cooling microchannel heat exchanger.
REFRIGERATED DISPLAY CABINET INCLUDING MICROCHANNEL HEAT EXCHANGERS
A refrigerated merchandiser includes a product display area having multiple shelves. An air return passage is defined below the shelves. A first fan is disposed at a downstream end of the air return passage. An air distribution passage is connected to an outlet of the fan and is disposed behind the shelves. A top passage is disposed above the shelves. At least one microchannel evaporator at least partially surrounds the first fan. The at least one microchannel evaporator includes at least one bend.
REFRIGERATED DISPLAY CABINET INCLUDING MICROCHANNEL HEAT EXCHANGERS
A refrigerated display case includes a housing surrounding multiple shelves. An air return passage is defined below the shelves. A fan is disposed at a downstream end of the air return passage. An air distribution gap is connected to an outlet of the fan and disposed behind the shelves and a top passage is disposed above the shelves. At least one microchannel heat exchanger connects the air distribution gap to the shelves.
MERCHANDISER
A refrigerated merchandiser is provided including a case having a first case section. The first case section defines a first product display area and an air passageway. The air passageway supports a fan and is in fluid communication with an airflow inlet and an airflow outlet. The air passageway is at least partially defined by a refrigeration system including an evaporator. A portion of the air passageway is further defined by a plenum having a stepped profile configured to channel and adjust a direction of an airflow within the first air passageway prior to entering the evaporator. The refrigerated merchandiser may further include a second case section defining a second product display area and including a glass panel. A first airflow portion of an airflow is configured to flow through the airflow inlet toward the evaporator and a second airflow portion is configured to flow through a second airflow outlet via an evaporator bypass channel. The first airflow portion is cooled by the evaporator and the second airflow portion is uncooled by the evaporator. The second airflow portion may be further directed through the second airflow outlet over an exterior of the glass panel of the second case section.
Self-contained refrigerated case with a self-contained condensate removal system
A preferred embodiment utilizes the waste heat from a refrigerant cycle to aid in the removal of condensate from a refrigerated case used primarily by grocery stores. Certain embodiments use a heating element to boil off condensate or a pump to remove the condensate. Another embodiment utilizes a wicking element and a shroud that directs hot air from the condenser through the wick thereby increasing the condensate evaporation rate. Yet another embodiment utilizes the hot gas tube from the refrigeration system routed through the bottom of the condensate tray to pre-heat the condensate to accelerate evaporation. Alternative embodiments combine certain features to create even more efficient system such as a heating element used with the wick system or the hot gas system used with the wick system. In some embodiments, a mold and mildew inhibitor is added to the condensate to maintain cleanliness.
Modular refrigeration systems
The present application provides a refrigerated merchandising case. The refrigerated merchandising case may include a refrigerated product area, a rear panel with a roller channel and a number of support apertures, and a number of shelves with a roller and a number of attachment prongs. The shelves may maneuver along the rear panel via the roller within roller channel and attach via the attachment prongs and the support apertures.
MERCHANDISER
A refrigerated merchandiser includes a case, a first case section defining a first product display area and a first air passageway having a first airflow inlet, a first airflow outlet, and a second airflow outlet, and a second case section having a glass panel through which a second product display area is visible. Moreover, the refrigerated merchandiser includes a fan positioned in the first air passageway to generate an airflow that is separated into a first airflow portion and a second airflow portion at or upstream of an evaporator. The first airflow portion is configured to flow through the evaporator and through the first airflow outlet. The second airflow portion is configured to bypass the evaporator via a bypass channel and flow through the second airflow outlet. The second airflow outlet is oriented to direct the second airflow portion over an exterior of the glass panel.
REFRIGERATION BIN
A refrigeration bin is disclosed. The bin includes a product display area defined by four side walls, a floor, and an access opening. Also included are an air supply vent on each of a first opposing set of the side walls, and an air return vent near each of a second opposing set of the side walls, in which the second opposing set of the side walls are adjacent to the first opposing set of the side walls. There is a return air duct, a first end of the return air duct in air flow communication with the air return vent, and a supply air duct, the first end of the supply air duct in air flow communication with the air supply vent, allows air flow in the display area. A cooling device is included for cooling air before it enters the supply air duct. The refrigeration bin can be useful to showcase foodstuffs in grocery stores and the like.
Refrigerated Display Case Condensation Management Systems and Methods
Condensation management systems and methods including a control unit and a plurality of auxiliary fan devices. The control unit includes fan, heating element and controller maintained by a housing, and a sensor. The auxiliary fan devices each include a fan electrically connected to the controller and that can be selectively installed to a refrigerated display case apart from the housing. The controller operates to prompt operation of the heating element, the fan, and the auxiliary fan devices in response to sensed information.
