Description

(54) cooler

. .. one-..

The invention relates to refrigeration equipment, namely, refrigerators with forced air, mainly for storage of blood and other biological products.

14, a refrigerator is known for storing biomaterials with forced air circulation, including a heat-insulating chamber, an air-cooled adapter in it and a box-shaped air duct connected to it, in the side walls of which there are openings for refrigerated air to enter the chamber. .

However, the design of this refrigerator does not allow a uniform distribution of temperature throughout the chamber volume, as a result of which the products located in the immediate vicinity of the duct are cooled much more strongly than others.

The closest to the invention of the technical essence and the achieved result is a refrigerator of similar purpose.

containing a heat-insulated chamber with shelves and two {o, evaporator, fan, panel with apertures, installed along one of the walls with the formation of a vertical channel for the passage of cooled (x air 2.

However, in this refrigerator, the temperature throughout the chamber volume is unevenly distributed, since the air warmed by products returns to the evaporator zone along the inner panel of the door, therefore, nearby

10 1 Juducts have a higher B12 temperature than in other areas of the chamber.

The purpose of a shadow is to ensure a uniform temperature distribution over the volume of the refrigerator chamber by separating heat from the rest of its mass.

This is achieved by the fact that in a refrigerator containing a heat-insulated chamber with a polio and two {sho,. evaporator, fan, panel with holes, ycrakoBneiHy along

Claims (2)

20 of one of the walls with the formation of a vertical channel for the passage of cooled air, along the wall opposite to the panel, ushov;} ena additional; a panel with a hole 3.9 mi with the formation of a channel for the passage of heated air, communicated with the area of the evaporator. In this case, the holes in the panels are made under the upper shelves. . In addition, the additional panel has protrusions under the upper shelves, and the holes are made on these protrusions. The main panel is installed along the back wall of the refrigerator, an additional panel along the door and in it in the area where the evaporator is located, holes are made, and under it there is an edge for blocking the access of air directly from the chamber to the evaporator zone. FIG. 1 shows a schematic representation of the proposed refrigerator; a general view; in fig. 2 - the same, front view without doors. The refrigerator contains a chamber 1 formed by a heat-insulated cabinet 2 and door 3. The chamber 1 has shelves 4 for placing food, and in its upper part are an evaporator 5 and a fan 6, separated from the cooled volume by a heat-insulated unit 7. Along the back walls. ki cabinet 2 installed panel 8 p. holes 9, the edges of which are near the side walls, forming gaps 10 for the passage of air into the chamber 1 volume. The vertical air channel 11 between the back wall of the cabinet 2 and the panel 8 is connected to the evaporator 5 placement area and the ventilation space (6.) Another panel 12 with holes 13 is installed with an air channel 14, which is connected to the evaporator placement area 5 through holes 15 made in the top of the panel 12. The latter also has lugs 16 with holes 13 under the upper shelves 4 and edge 17 dl shut off the air supply directly from the volume; chamber 1 to the evaporator zone 5. When the refrigerator is working, the cooled air from the evaporator 5 through the fan 6 enters the channel 11, and from here through the openings 9 and the gaps 10 to the volume of chamber 1, The shelves 4 are washed with cooled air both from the sides and from above. Use in pre) lagable cold Ilnyk supplemental channel 14 for discharging air from the heating chamber 1 into the evaporator area 5, the presence of the openings 9 and 13, formed respectively on the panels 8 and 12, allows to significantly increase uniformity; temperature distribution over the chamber volume and thereby improve the storage conditions of biological products. In the described refrigerator, the deviations from the set temperature throughout the chamber volume are within ± 1 ° C, while in the prototype the temperature unevenness is ± 2 ° C. Invention 1. Refrigerator containing a heat-insulated chamber with shelves and a door, an evaporator , fan, panel with holes, installed along one of the walls to form a vertical channel for the passage of cooled air, so that, in order to ensure uniform distribution of temperature over the chamber volume, separation of the heated air from the rest of its mass, along the wall,: pro-. An opposite panel is installed, an additional panel with openings is formed to form a channel for the passage of warm air connected to the evaporator placement zone, with the openings in the panels underneath the upstream shelves. 2. Refrigerator according to claim 1, that is, and with the fact that. the additional panel has projections under the overly arranged shelves, and the holes are made on these projections. 3. The refrigerator according to claim 1, in accordance with the fact that the main panel is installed. along the back wall, additional panel. - along the door, and in it in the zone where the evaporator is located; 7nena - open holes, and under it there is a rib to block the access of air directly from the chamber to the zone of the evaporator.
