A product merchandising system includes a housing having a top surface, two side surfaces spaced apart from one another defining a width-direction of the housing, and a front surface and rear surface spaced apart from one another defining a depth-direction of the housing. The system includes a product support system configured to support rows of products along a width of the housing, each row disposed at a position along the depth of the housing, the first row being towards the front surface of the housing. A cooling system includes a cooling system including a cooling heat exchanger generating an airflow, a deflector configured to direct the airflow through the cooling heat exchanger and towards a bottom of the housing, and a nozzle below the deflector and configured to direct the airflow towards a bottom of the housing through an outlet aperture and between a first two rows of products.

The invention relates to a fridge for thawing and aging, and it comprises a body 11 having inner space 12, a cooling unit 13, an inner panel 21 forming an inner wall facing the inner space 12 and being applied or impregnated by the functional materials 22 being capable of emitting anions or far-infrared radiations, a heating unit and a fan unit 30 whose exhaust hole 33 is disposed near to the inner panel 21 to exhaust the air against to or along the inner panel 21 of the body 11.

A refrigeration device has a cabinet having a pair of refrigerated interior spaces and an upper compartment which houses removable compressor and evaporator modules. An air supply plenum is positioned between the refrigerated spaces to evenly provide cold air. The evaporator module has a removable, thermally insulative cover to facilitate servicing.

The present invention provides a refrigerator, comprising a storage compartment, a refrigeration air passage configured to supply refrigeration air and a top air passage. The top air passage is provided at a top wall of the storage compartment, comprises a rear end air inlet, a front end air inlet and a mixed air outlet opening downwards, and is configured to receive refrigeration air blown from the refrigeration air passage via the rear end air inlet, receive return air returning from the storage compartment via the front end air inlet, and allow the refrigeration air and the return air to flow into the storage compartment in a mixed manner via the mixed air outlet.

A commercial refrigerator for energy savings and a method to operate thereof. The refrigerator comprises a cabinet, the cabinet with a first cavity with an inner part, an access to said inner part and an air chamber set in the inner part, the air chamber comprising a fan which makes the air pass through an evaporator, a thawing resistance which thaws the evaporator, a cover with first slits which allow an air flow emanating from the first cavity towards the inner part of said air chamber and second slits that allow air flow cooled by the evaporator emanating from the inner part of said air chamber to the first cavity; temperature sensors set within the inner part of the air chamber, a first temperature sensor set between the first slit and the fan and a second temperature sensor set between the evaporator and the second slits, said sensors connected to an electronic control.

The method collects temperature data from a sensor and temperature data from another sensor within an air chamber; compares the data from one sensor to the data from the other sensor to obtain a temperature value and calculates the stability of the data from the comparison; averages said data such that the temperature obtained is presumed as very close to the temperature of the products within the inner part of a chamber; de-energize a compressor by means of an electronic control.

A refrigeration system for cooling a plurality of compartments includes a chiller and a duct providing fluid communication between the chiller and a plurality of compartments. The refrigeration system additionally includes a plurality of individually controllable fans that individually draw cooling fluid through the duct from the chiller and into a corresponding one of the plurality of compartments. A plurality of sensors monitors the temperature and pressure of the cooling fluid circulating through the chiller. A controller individually controls each of the plurality of individually controlled fans based on the corresponding temperature inside each of the plurality of compartments.

An embodiment of a cold storage system includes a housing further including a chamber having a front opening closeable by an outer door and a back wall opposite the front opening, one or more outlets defined in the back wall, and one or more inlets defined in the chamber more proximate the front opening than the back wall. In addition, the cold storage system includes a refrigeration module operably coupled to the chamber. The refrigeration module includes an evaporator positioned vertically higher than the chamber, a blower configured to generate an airflow that is in thermal communication with the evaporator, and ducting configured to circulate the airflow between the chamber and the evaporator via the inlets and the outlets such that the airflow is directed through the outlets into the chamber and then from the chamber into the inlets to cool the chamber.

A refrigerator includes an inner case including (i) a refrigerating case that defines a refrigerator compartment and (ii) a freezing case that defines a freezer compartment, an outer case disposed outside the inner case, a connection duct disposed between the inner case and the outer case, and a refrigerator compartment cold air supply duct that is detachably coupled to a rear inner surface of the refrigerating case and in fluid communication with the connection duct. The connection duct and the refrigerator compartment cold air supply duct are in communication on a rear surface of the refrigerating case with the refrigerating case interposed therebetween, thereby reducing the area occupied by the refrigerator compartment cold air supply duct disposed in the rear inner surface of the refrigerator compartment.

The present invention relates to a refrigerator having a separate deep-freezing space which is partitioned inside a storage space of the refrigerator. Provided is a refrigerator having a flow path which allows cold air to circulate inside a deep-freezing chamber. According to an embodiment disclosed in the present document, a flow path portion is formed on one part of the inner surface of the housing which forms the inner space of the deep-freezing chamber. The flow path portion is formed in a stepped shape on the inner surface of the housing.
