Description

The technical field to which the utility model relates.

The invention relates to a technique for storing food products and can be used to cool and freeze food.

State of the art

Known two-compartment refrigerators containing a refrigerator and a freezer, one of which (refrigerating) are external, and the second (freezing) are internal, each of the chambers is designed to store products in a certain temperature range, while a chamber designed to store food at a lower temperature is located inside the chamber, designed to store food at a higher temperature (see for example: ZIL-Moscow refrigerator KX-240. Repair of domestic refrigerators. Refrigeration unit ika. M .; 10.06.2006) [1].

The device [1] is the closest and accepted as the closest analogue.

The known device [1] as well as the claimed one contains the following essential features: a refrigeration unit including several refrigerated chambers, one of which is external, and the second is internal, each of the chambers is designed to store products in a certain temperature range, and the chambers are intended for storage food at low temperatures, located inside the refrigerator, designed to store food at higher temperatures.

A disadvantage of the known device is the high energy consumption for maintaining the specified temperature conditions in the reflux chambers, since when the outer door is opened, the temperature rises not only in the outer chamber, designed to store food at a higher temperature, but also in the inner chamber, designed to store food at lower temperature.

In addition, the temperature regime created in one chamber depends on the temperature regime created in another chamber. When the temperature regime in one chamber changes, the temperature regime in the other chamber changes accordingly, which necessitates additional energy expenditures to adjust the temperature regime.

Utility Model Disclosure

The technical problem, which this utility model is aimed at, is to expand the functionality of the device due to the independence of the temperature regime created in one chamber from the temperature regime created in another chamber and reduction of energy consumption to maintain the required temperature regimes.

To solve this technical problem in relation to refrigeration units used on marine vessels, the proposed refrigeration unit contains several refrigerators, one of which is external, its hull is located inside the ship's hull, and the remaining refrigerators are internal, each of the refrigerators is designed to store food in a certain temperature range, and a cold chamber, designed to store food at low temperatures, is located inside a cold chamber, designed to store food ucts at higher temperatures, the casing door and the door contact points with the outer sheath and each inner refkamery covered with insulating material.

The most optimal refrigeration unit consists of three refrigeration chambers, while the first cold chamber - the external one is designed to store food at temperatures from + 10 ° С to 0 ° С, the second refrigeration chamber located inside the first refrigerator is designed to store food at temperatures from + 3 ° C to -8 ° C, the third cold chamber located inside the second cold chamber is designed to store food at temperatures from -3 ° C to -20 ° C.

Utility Model Implementation

The refrigeration unit consists of a hull and a door and is located inside the hull of the vessel. Inside the case of the refrigeration unit is located the first refrigeration chambers (external), designed to store power at temperatures from + 10 ° C to 0 ° C. The casing of the refrigerator chamber, the door and the contact points of the door with the casing are covered with heat-insulating material.

Inside the first refrigerator there is a second refrigerator equipped with a door, in which a lower temperature is maintained from + 3 ° C to -8 ° C. The shell of the second cold chamber, its door and the contact points of the door with the shell are also covered with insulating material.

Inside the second cold chamber there is a third cold chamber equipped with a door, in which the temperature is maintained from -3 ° C to -20 ° C. The casing, the third cold chamber, its door and the places where the door contacts the casing are also covered with insulating material.

Each refcamera is equipped with any known independent refrigeration unit (source of cold) that automatically maintains the set temperature in the refcamera.

When opening the door of the case of the refrigeration unit due to the thermal insulation of the second refrigeration chamber, the temperature regime is maintained in it. Similarly, when you open the door of the second refrigeration chamber due to the thermal insulation of the third refrigeration chamber, its temperature regime is maintained in it.

Since the third (freezing) refrigeration chamber is used less often, since it contains products of long storage, and the second refrigeration chamber, in which products of medium shelf life are used, is used less often than the first refrigeration chamber, in which products of short storage are stored, the energy consumption for maintaining set temperature conditions in these quiet chambers will be minimal.

In addition, the temperature conditions of the refrigeration chambers, due to their thermal insulation from each other, are independent, which also leads to minimal energy consumption to maintain a given temperature regime in them.
