The invention relates to refrigeration and can be used in refrigeration units for storing products

The purpose of the invention is to reduce energy consumption by utilizing the heat generated during the compression process.

Freon refrigerator works as follows

Compressor 1 compresses the freon vapors after the evaporators 7 and 8 and pumps them through the discharge pipe 5 to the condenser 6, from where the liquid freon, having supercooled in the recuperative

The heat exchanger 20 and separated. The drawing shows a diagram of the fre-Yu from the moisture in the filter-drier 21, enters the expansion organ-22, then into the evaporator 7, where it begins to boil and then enters the

Onovogo refrigerator,

The freon cooler contains a compressor 1 with a cooling jacket 2 and an oil bath 3, suction and discharge pipes 4, 5, respectively, a condenser 6 combined with liquid and steam pipelines with evaporators 7 and 8. The refrigerator is equipped with steam and liquid combined in an additional closed loop pipelines 9, 10, respectively, an evaporator 11 and a condenser 12, as well as an ejector 13 and a heat pump 14. A heat pump 14 is connected along the low-pressure line with a steam line J5 to the inlet of a condenser 12 and a liquid By means of the high-pressure line, the heat pump 14 is connected with the steam line 17 to the upper part of the cooling jacket 2, and the liquid pipe 18 about passing through the oil bath 3 of the compressor 1, to the lower part of the cooling jacket 2 about the Ejector 13 is installed in an additional closed circuit on the steam pipe 9 between the evaporator 11 and the condenser 12, connected by the steam pipe 19 with the upper part of the cooling jacket 2, which is filled with a lightly boiling refrigerant (freon). 5 boprovod compressor 1 is placed on the site liquid pipe line 17 after the high pressure oil tank 3 of the compressor.

Condenser 6 is connected through a recuperative heat exchanger 20, filter dryer 21 and expansion body 22 to an evaporator 7, which is connected through an expansion body 23 to an evaporator 8 and then through a recuperative heat exchanger 20 to the suction inlet of compressor 1.. On the additional circuit, including a condenser 12 and an evaporator 11, a filter drier 24 and an expansion body 25 "are installed

Nominal heat exchanger 20 and separated from moisture in the filter drier 21, enters the expansion organ 22, then into the evaporator 7, where it begins to boil and then enters the

body 23, from where it follows to the evaporator 8, where it finally boils away. Freon through the liquid line 17 of the high pressure line of the heat pump 14 passes through the oil bath 3, where it is heated and further heated in the section of the discharge pipe 5, and then flows into the cooling jacket 2 where it boils. The resulting high pressure and temperature vapors flow in parallel to the ejector 13, where the vapor from the evaporator 11 is sucked in, and also through the steam pipe 15 to the heat pump 14, from where these vapors press liquid freon into the liquid pipe 18 of the high pressure line of the heat pump 14. Compress in the ejector 13, freon enters the condenser 12 of the additional circuit, and steam from the thermal pump 14 is periodically diverted there via the steam pipeline 15. A part of the liquid freon flows through the liquid pipeline 16 to the low-pressure line 16 the heat pump 14, and the rest of the freon passes through the filter-drier 24, the expansion body 25 into the evaporator 11, where it boils, extracting heat from the product,

In the proposed freon refrigerator, cold is produced in two unrelated circuits.

In one, as a result of the operation of the compressor, and in the other, as a result of the operation of the ejector using the heat generated by the compressor as a result of compression, and due to the utilization of heat released during compression of the vapors in the compressor, energy consumption is saved.
