State of the art

The energy efficiency of existing equipment used to cool and preserve raw and cooked products, materials, substances, crops is one of the indicators that determines the commercial attractiveness of such equipment. The practice of using this equipment as an example of domestic refrigerators demonstrates that there is not a complete filling of the total usable volume intended for cooling and preservation. The technological specification SNM No. 24247 “Energy Efficiency of Cooling Systems” created in Germany allows us to implement, as it says: “a differentiated assessment of the energy efficiency of a refrigeration unit and its components using simple energy efficiency factors”. This takes into account: energy efficiency of compression refrigeration machines, cold production process ηKS, heat transfer efficiency ηWT, refrigerant transport efficiency ηFT, cold utilization efficiency ηQo, overall energy efficiency ηges of the refrigeration unit is a derivative of the four above factors. When determining these coefficients, all sorts of parameters are taken into account and introduced into the calculation, except for one - there is no indicator of the occupancy of the usable volume used for storage and cooling. For consumers, the main indicator of efficiency is the ratio of the cost of energy expended to the amount of refrigerated (stored) products. As a result of a long observation and measurements, the author found that, despite the apparent completeness of filling, the volumetric filling indicator, using the example of household refrigeration equipment, is no more than (30-35)%. Existing models of refrigeration equipment, despite their small size, autonomy and the possibility of zone temperature adjustment (for example, F25D 13/04) also do not take this indicator into account. It is the figure characterizing the volumetric filling obtained by the author that determines the only possible direction of increasing the commercial efficiency of such equipment with the current level of technological development. This problem is solved by the claimed device, the invention is a lid-cooler.

The technical result of using the proposed solution implemented in the claimed device, invention, lid-cooler (options) is the most efficient use of the energy of the cold source due to its placement inside the volume of dishes (containers), the contents of which need to be cooled, or due to the fact that the cooler lid so tightly covers the cooled utensils (capacity) that the loss of cold is much less than the amount of cold required to cool the contents of the utensils (capacity).

Disclosure of invention

Lids / corks (hereinafter referred to as the lid) are usually performed as monolithic, rarely combined, depending on what task the lid solves and what requirements are imposed on it. To achieve the goal of the claimed device, invention, it is necessary that the cover becomes a source of cold. The simplest technically feasible method is the location of the source of cold on the surface / side of the lid facing the inside of the closed container, the covered space. Such a source of cold, for example, can be an evaporator, which is part of the refrigeration unit of the refrigerator, while the remaining parts of the refrigeration unit (condenser, motor, compressor, controls, power input, etc.) are located, as an option, on the back of the lid, the outer , in relation to the internal volume of the container closed to it, the space covered by it. This arrangement of the cold source on the lid is the most optimal for cooling and preserving raw / cooked products, substances, materials, crops or individual elements that need cooling, and ensures maximum energy efficiency.

In order to achieve greater energy efficiency, the lid is multilayer, of the materials known in the art today, which will provide mechanical strength and high thermal insulation properties. For convenience of description, we use FIG. 1, we denote the surface of the lid facing the inside of the space covered by it as surface (A). The material of the layer that formed the surface (A) is denoted by M (A); it should not have any effect on the contents in the container and be inert with respect to the contents of the container. The surface of the lid facing the external environment is designated as surface (B). This surface is an accessory of the top layer of the cover, and we will designate it M (B), which is made of materials providing the mechanical strength of the cover and its geometry. As an option, parts of the refrigeration unit are attached to the M (B) layer. Between the layers M (A) and M (B) is a layer of thermal insulation. Let's designate it - M (C). In the layers M (A), M (B) and M (C) technological openings / channels should be provided to ensure the technological functionality of the elements and devices installed on the surfaces of the layers M (A) and M (B), as well as inside them, and jumpers connecting the layers together and creating structural rigidity. Along the perimeter, the layers M (A) and M (B), as well as the layer M (C) along the perimeter and in area, are interconnected by any method known in the art of today, providing mechanical strength, maintaining the shape and geometry of the lid.

Implementation FROM

Structurally (Fig. 1) the lid covering the dishes / container covering the space, pos. 1, can be made of tightly adjacent layers M (A), M (B) and M (C), and with a gap or between all layers, and with a gap between a tightly adjacent pair of M (A, C) and M (B) or with a gap between a tight-fitting pair of M (B, C) and M (A). Alternatively, the adherence of the layers may be local combinations of the above. The presence of free space between the layers allows you to place in it some elements of the refrigeration unit pos. 2, and some, for example, thermostat control, power control, indication to bring to the surface (B).

The surface (A) can perform several functions, for example: it can be the base surface on which the evaporator is mounted and fixed, connected to the condenser using tubes, pos. 3, located and fixed on the surface (B), through technological holes passing through the heat-insulating layer (C) separating M (A) and M (B); surface (A) itself may be a source of cold, in which case the evaporator will be formed inside layer M (A). The condenser can be installed (options) and mounted on the surface (B) as an independent element of the refrigeration unit or integrated into the layer M (B), which will contribute to a more aesthetic appearance of the lid and its greater mechanical protection.

In order to eliminate the loss of cold through the side surfaces of the tank, the lid is, for example, in the form of a cap, that is, the lid covers the side surfaces of the tank, covers the axillary space (options), for example, to the surface on which the tank is installed, while at the contact point of the lid with the surface on the lid, as an option, is fixed by any sealing method known in the art of today, pos. 4. To reduce losses through the bottom of the tank, the tank is placed on a heat-insulating stand, pos. 5. The snug fit of the lid to the stand is ensured by any method known in the art of today. And this stand can be a container for collecting condensate formed during operation of the cover.

The stand may have a connection (options) with the cover and its parts, made by any method known in the art of today, ensuring the implementation of the claimed properties of the cover. A variant is possible when the lid contains a window that can be “glazed” to control the axillary space. Also, as an option, the cover may contain a light source illuminating the axillary space, powered by (options) from an autonomous source located in the body of the cover, or from the network through the input on the outside of the cover or otherwise. As an option, it is possible to design a cover with a fan located on the surface (A) or otherwise (options), for more rapid equalization of the temperature gradient in the axillary space. A variant of the cover is possible when the layer M (A) contains at least one heating element, either on the surface (A) or built into its body, which will accelerate the defrost or heat the product in the tank. The power supply to the thermocouple is carried out by any method known today (options), for example, through the input on the surface (B) or, as an option, through the stand and the intermediate connector between the stand and the cover. Moreover, part of the lid (options), for example, containing at least one heating element, can be made removable, detachable from the lid, which indicates the design of the lid with a variable axillary space. An option is provided for a stand containing a power input with an intermediate power transfer connector to the refrigeration unit and at least one heating element. An embodiment of a cover comprising at least one through hole is possible. A variant of the lid is possible, in combination with a stand, as a single device forming a cooking container. In this case, as an option, the inner surface of the cooking vessel is the surface of the evaporator, and the outer side surfaces, for example, are a condenser, while the devices of the refrigeration unit are contained in the space between the evaporator and the condenser, between the walls formed by them, and the control elements placed on the outside of M (B).
