Description

(54) COMPRESSION REFRIGERATOR

a low pressure temperature circuit, and the condenser is divided into sections, each of which is the same as the capillary tubes and regenerative heat exchangers located in the respective circuits.

The drawing shows a motor-compressor, a cut, and a diagram of a compression refrigerator with autonomous high-temperature and low-temperature circuits.

All parts of the compressor are mounted on the core 1, which is suspended on the springs 2 in the casing 3. The crankshaft 4, on which the rotor 5 is pressed, rotates in the bearings of the casing 1 of the compressor. The stator 6 is bolted 7 to the compressor housing. The cylinders 8, cast together with silencers, are mounted on the compressor housing at an angle of 180 ° on the four control pins 9 and bolts 10 to it. The hollow parts 11 are soldered to the yoke 12 and reciprocate in the cylinders as a result of the yoke a slider 13 located on the crank neck of the shaft 4; Through the tube 14, the compressed vapor is injected into the high-temperature autonomous circuit, which consists of a condenser 15, a capillary tube 16, a regenerative heat exchanger 17 and a positive evaporator 18. The vapor of freon from the evaporator through the nozzle 19 is sucked into a sealed chamber 20, which is formed by the upper lid 21 and the partial to it with a plate 22. From the chamber 20, a pair of freon through the suction inlet 23 is sucked into the cylinder 8 through the muffler suction unit. Freon vapor is injected into the circuit with a min into the hermetic chamber 30, which is formed by the casing 3 and the plate 22,

The compression cooler works in the following manner. Foods are cooled to the required temperatures using stand-alone KbHTypoiB, whose evaporators 18 and 28 are located in isolated chambers. The compressor and electric motor are in a generally hermetically sealed casing, the internal volume of which is divided by plate 22 into two hermetic chambers 20 and 30. When the compressor is operated, freon vapors from the evaporator 18 and 28 along suction tube 19 and 29 into hermetic chambers 20 and 30, and from there to the cylinders 8 of the compressor. Compressed freon vapors from cylinders, having the required cooling capacity, are injected under pressure through pressure pipes 14 and 24 into condensers 15 and 25, which are divided into sections.

Vapor compression occurs during reciprocating movement of the pistons 11. Porpsh 11 and the sleeve 12 attached to them are moved as a result of the action of the slide 13 located on the crank shaft neck 4. From the condensers the liquid freon flows through filters 16 into the capillary tubes 16 and 26 which reduce the condensation pressure to the required boiling pressure of freon in autonomous evaporators 18 and 28. When passing through capillary tubes, the liquid freon is cooled by cold vapor of freon going through the suction tubes 19 and 29 from the evaporators, i.e. in regenerative heat exchangers 17 and 27.

Due to the presence of autonomous circuits operating from isolated cylinders with the required cooling capacity, it is not necessary to use flow switches of the cooling agent from one circuit to another, which increases the efficiency and cost effectiveness of the refrigerator. The presence of separate hermetic suction chambers allows you to select the optimal suction and discharge pressures, each of which corresponds to the required temperature of the refrigerating chamber. The design of the refrigerator with autonomous circuits allows you to select the optimal modes of their operation and increase the specific refrigeration capacity of one, as well as reduce the consumption of consumed energy and expand its technical capabilities.
