Abstract

FIELD: objects of personal use, refrigeration engineering.

SUBSTANCE: household compression refrigerator consists of housing, compressor, condenser, filter - dehydrator, vaporiser, lamp bar. Compressor, with condenser and filter- dehydrator are separated into one block, from the fridge housing and placed away from the placement, where there the refrigerator is used. The outrigger block, heat-insulated by pipes, is connected to the vaporiser, placed in the housing.

EFFECT: improving the power and operational potential of a refrigerator.

Description

The invention relates to refrigeration, in particular to small refrigeration machines.

Known refrigerator containing a cabinet, condenser, evaporator, filter drier, hermetic compressor, temperature controller and start-up relay / Weinberg B.S., Vine L.N. Household compression refrigerators. M .: Food industry, 1974, p.25-30 /.

The main disadvantages of this refrigerator

When you turn on, turn off, and generally when the hermetic compressor is operating, noise is generated, the heat released in the hermetic compressor, condenser and filter drier is removed to the room, which creates some discomfort, especially in summer. In addition, the energy and operational capabilities of the refrigerator are not fully utilized.

Known refrigerator containing a cabinet, compressor, evaporator, condenser, filter drier, temperature controller, backlight (DE 10225833 A1, F25 39/00, 2004.01.08), in which the condenser is placed in the basement of the building.

The main disadvantages of this technical solution

When you turn it on, off, and generally when this refrigerator is working, noise is created by the motor and compressor.

The condenser is not blown by natural moving air flows, the volume of the vegetable chamber is reduced, the heat generated in the hermetic compressor and filter drier is removed to the room, which creates some discomfort, especially in summer. The operational and energy capabilities of the refrigerator are not fully utilized.

The aim of the invention is to eliminate these disadvantages and improve the energy and operational capabilities of the refrigerator.

This goal is achieved using a household compression refrigerator containing a cabinet, compressor, condenser, filter drier, evaporator, backlight, and the compressor with condenser and filter drier are allocated in a separate unit, remote from the refrigerator and located outside the room where it is used a refrigerator, while the remote unit is thermally insulated tubes connected to the evaporator located in the cabinet.

This goal is achieved due to the fact that the refrigeration unit of the refrigerator is divided into two blocks, 1 and 2. FIG. 1.

Block 1 is located inside the cabinet 3. The cabinet is installed indoors and contains an evaporator 5, a temperature controller 4, a capillary tube 6, and thermally insulated tubes 7 and 9 are connected to block 2.

Block 2 contains a compressor 10, hermetically connected to a condenser 12, the output of which through a filter drier 11 with a heat-insulated tube 7, passed through an opening in the wall 8, and a capillary tube 6 is connected to the evaporator 5, which is located in the freezer of block 1. The opposite side of the tube the evaporator 5 is connected by a thermally insulated tube 9 with the suction pipe of the compressor 10.

Block 2 is located behind wall 8, i.e. fixed on the outer surface of the wall of the building.

Since part of the refrigerator is taken out onto the street, specifically, compressor 10, condenser 12 and filter drier 11, in order to reduce the dimensions of block 2, improve aesthetics and simplify installation, the condenser 12 is bent (Figure 2), and inside it on steel strips 17 and 18, the compressor 10 is attached. The area of the capacitor 12 is not changed. The supporting frame of this unit is a steel sheet on which a condenser cooling tube is soldered. Fasteners 14, 15 and 16 are welded to the sheet by which this unit is attached to the outer surface of the building wall.

Block 1 is located indoors and contains a thermally insulated cabinet with a front door 3, with three separated chambers, a temperature controller 4 and an evaporator 5, Fig. 1.

An evaporator 5 is placed in the upper chamber of the cabinet, which is connected to block 2 by thermally insulated tubes 7 and 9.

The proposed refrigerator consists of a cabinet 3 with a front door, which is divided into heat-insulated chambers, a compressor 10, a condenser 12, a filter drier 11, a capillary tube 6, an evaporator 5, a start-up relay, and consists of two units, one of which contains a cabinet 3 (Fig. .1) with an evaporator 5, a capillary tube 6, a temperature controller 4 and is installed in the room, and another one containing a compressor 10, a condenser 12 and a filter dryer 11, is made as a separate unit and is located on the wall from the outside of the room. The blocks are connected to each other by heat-insulated tubes 7 and 9, which are passed through the holes in the outer wall of the room 8. The temperature mode is set by the temperature controller 4 installed in the cabinet 3.

This design of the refrigerator characterizes its new features that can achieve the goal, namely: as a result of the changes due to more intensive cooling of the compressor and condenser, the energy characteristics of the refrigerator are significantly improved, noise in the room is reduced due to the fact that part of the refrigerator unit, i.e. compressor, condenser and filter drier, taken out to the street. The heat generated by them does not spread in the room, which is especially significant in the summer.

The refrigerator works as follows.

The blocks are interconnected by heat-insulated tubes 7 and 9 (Figure 1), which are passed through the holes in the outer wall 8. With this arrangement of the refrigerator elements, the compressor 10 compresses the refrigerant and delivers it to the condenser 12, from where it is through the filter dryer 11, through the holes in wall 8 through pipe 7 and capillary tube 6 enters the evaporator 5. Due to throttling, the refrigerant boils at a negative temperature and removes heat in the refrigerator. Through the heat-insulated tube 9, the refrigerant is returned to the suction pipe to the compressor 10.

Compared with the prototype of the claimed development has the following advantages:

1. The condenser, filter drier and compressor are intensively cooled by the environment (outside air). As a result, the energy characteristics of the refrigerator are improved,

2. In the room where the refrigerator is installed, heat from the compressor, condenser and filter drier will not be distributed, which is especially significant in the summer period, i.e. significantly improves the microclimate in the room.

3. No noise will be heard when turning on, turning off, and operating the refrigeration unit.

4. The volume of the vegetable chamber increases and its configuration is changed to a more convenient one with a vertical back wall. Currently, the development is undergoing laboratory tests.
