(54) CHOLAILIC CA.MERA FOR STORAGE

FOOD PRODUCTS

The invention relates to the refrigeration industry, namely, to refrigerators for storing food.

A known refrigerating chamber for storing products, including thermal protection enclosures, is unsaved. a discharge channel, a false ceiling, and two vertical screens installed with the formation of a U-shaped gap between them and the thermal insulation fences of the chamber (11.

. Another well-known refrigerating chamber is a heat-insulated casing, along the inner walls of which there are screens with the formation of a wall channel along the entire perimeter of the chamber, inside of which an air cooler with a fan 2 | is mounted.

Also known is a cooling chamber for storing ping products containing heat-insulating panels, air coolers with fans, two vertical screens installed with a gap with an upper heat-enclosing plate parallel to the side heat-enclosing panels and 3yioiiuix with the last air-flow channels, and a perforated plate for the delivery of the flow plate of the flow plate and the flow plate of the flow plate. working volume kz. measures {3J.

The disadvantage of these refrigeration units is that; the difficulty of creating a uniform temperature within the floor in their working volume.

The purpose of the invention is to provide a more uniform cooling of the products and a decrease in heat flows to the working chamber.

This is achieved by the 4jo refrigerating chamber equipped with two additional vertical screens placed with a gap with the upper heat shield panel parallel to the end heat shield panels and forming with the latter air ducts, a horizontal screen parallel to the lower tegrofragging panel with the formation of the outer channel and the vertical partition , while the perforated panel is placed over the horizontal screen with the formation of an air distribution cavity, vertical The partition is adjacent to the top and side heat shielding panels and perforars) van1 ((p1 panels, g air-breathing; 1 parts with ventilation fans mounted between the vertical partition and one of the additional vertical screens. Between the bottom heat shield and horizontal screen are set at an angle to the longitudinal axis of the septum chamber for equally distributed air supply to the air cooler.

The drawing shows schematically the proposed refrigerating chamber, a general view in three projections.

The refrigerating chamber for foodstuffs storage contains the top 1, bottom 2, side 3 and end 4 heat insulating panels, four vertical screens 5, installed with a gap from the top heat insulating panel 1 parallel to the side and end panels 3 and 4 and forming with the latter wall channels 6 for the passage of air, and a horizontal screen 7, located parallel to the lower thermal obstruction of panel 2, forming a stump from the last air channel 8, divided by a partition installed at an angle to the long axis of the chamber mi 9 for distributed air passage

The cooling chamber is also provided with a hollow vertical partition 10, which is attached to the top panel 1, side panel 3 and perforated panel 11 mounted above the horizontal screen 7 to form an air distribution cavity 12 for uniform cooling air to the chamber 13. Air coolers 14 with fans 15 cm3 between the vertical partition 10 and one of the end vertical screens 5.

We offer refrigerating chamber works as follows.

The air through the fans 15 enters the air coolers 14, where it is cooled with a simultaneous increase in the relative humidity. Next, the air enters the air distribution cavity 12 and through the perforated panel 11 penetrates into the working volume 13 of the chamber, where it blows the products from the bottom in a uniform flow and perceives the internal heat leakage. From the upper part of the working volume 13 through the gaps between the upper heat walling panel 1 and vertical screens 5, wall channels 6 and horizontal channel 8, air enters again into air coolers 14. Passage through wall channels 6 and horizontal channel 8, the air notes perceive all external heat sources, including radiant.

The proposed cooling chamber eliminates stagnant zones in the cooled volume, prevents external heat influxes from penetrating into it, shortens the cooling time of food, and reduces weight loss due to increased food storage.

Claims (3)
