A refrigeration system includes a first circulation fan electrically coupled to a power source via a first load wire. A relay is electrically coupled to the first circulation fan via a second load wire and to the power source. In an open position, the relay interrupts electrical voltage from the relay to the first circulation fan via the second load wire causing the first circulation fan to operate in a low-speed mode. In a closed position, the relay supplies electrical voltage to the first circulation fan via the second load wire causing the first circulation fan to operate in a high-speed mode. Operation of the first circulation fan in the high-speed mode reduces a defrost cycle time associated with the refrigeration system relative to operation of the first circulation fan in low-speed mode.

A refrigerated display case (20) having at least one unit composed of a plurality of wall assemblies, namely a bottom assembly (22.3), a rear wall assembly, and a top assembly (22.1), which delimit a cooling space at the bottom, the rear, and the top, and having a cooling unit (1) whose components include at least one evaporator (11), one condenser (13, 13), and one electric control unit (15). An environmentally friendly refrigerated display case (20) is achieved in that the cooling unit (1) includes at least two closed refrigerant circuits (10, 10), which convey propane as a refrigerant and are each provided with a compressor (12, 12), and in order to variably control the cooling output, at least one compressor (12, 12) is embodied with a speed regulation and at least one compressor (12, 12) is embodied for operation at a constant speed.

A showcase includes: a box-shaped case main body sectioned into a storage room and a machine room by a heat insulating bottom plate; article mounting shelves arranged in a plurality of stages in an up-and-down direction in the storage room; a circulating fan configured to circulate air from inside the storage room between the storage room and the machine room; and a cooler arranged in the machine room and configured to cool the air circulated by the circulating fan. The heat insulating bottom plate includes a first air inlet formed in a face facing the storage room, a second air inlet formed at a position that is in a face facing the machine room and does not overlap with the first air inlet in the up-and-down direction, and an inlet flow channel formed so as to cause the first and the second air inlets to communicate with each other.

A refrigerator is wall-mounted. The refrigerator has a frame with an insulated compartment supporting a plurality of shelves, a front panel covering the frame and having at least one window for displaying refrigerated articles supported by the shelves, at least one door to access the articles supported by the shelves, a cooling unit, an air recirculation system having a warm air collector for collecting warm air and having a warm air channel for directing air through the cooling unit to provide cooled air, at least one fan, and a cold air channel for directing the cooled air back into the compartment and a mounting for anchoring the refrigerator with respect to a wall. The thermal efficiency of the refrigerator may be enhanced as described herein.

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 method and system for dry aging the meat product uses a 12 volt DC powered portable unit comprising a plastic box configured for housing the primal cut of meat and placed inside a refrigeration system. The box is further equipped with an internal and external blower to control the air circulation and humidity respectively inside the box. A germicidal UV light disposed within the plenum in front of the internal blower to provide germicidal action on the dry aging meat product. A PCB controller placed on top of the box embedded with software and a humidistat to control the humidity inside the box and maintaining a closed micro environment to dry age the meat product with desired texture, flavor and tenderness.

An order fulfillment system having a frame defining a compartment therein that extends between a first space and a second space, and a first door coupled to the frame. The first door is movable between an open position providing access to the compartment from the first space, and a closed position blocking access to the compartment from the first space. The system further includes a second door coupled to the frame, wherein the second door is movable between an open position providing access to the compartment from the second space, and a closed position blocking access to the compartment from the second space. The system is configured such that the compartment has greater fluid communication with the first space compared to the second space when the first door is in the closed position and the second door is in the closed position. The system also includes an air movement device in fluid communication with the first space and the compartment, wherein the air movement device is configured to provide air from the first space into the compartment.

A cooling device contains a cabinet having a storage compartment. A partition member is configured to divide the storage compartment into at least two of a first space, a second space and a third space. An inner guide is provided with an air flow path including a first air supply duct configured to introduce the air into the first space and a second air supply duct configured to introduce the air into the second space. A fan is configured to generate air flow in the air flow path. A first air flow control device is provided on the first air supply duct to adjust an amount of air supplied to the first space. A second air flow control device is provided on the second air supply duct to adjust an amount of air supplied to the second space.
