(5) REFRIGERATING INSTALLATION. (ITS OPTIONS)

one

The invention relates to refrigeration engineering, in particular, to refrigeration units included in extensive refrigeration systems of large enterprises.

A known refrigeration unit comprising a circulation circuit for a refrigerant in which a throttle regulating device and an evaporator located inside the Q insulated chamber are installed, in which high-voltage electrodes l are also placed.

However, the known refrigeration unit has an insufficient shelf life of products due to the use of complex hedge; ore and significant energy consumption of the installation.

The purpose of the invention is to improve the storage conditions of products.

This goal is achieved by the fact that in a refrigeration unit the circuit after the throttle device contains a dielectric section, in the middle of which a conductive ring with a collector grid is installed, and one of the high-voltage electrodes is made in the form of a spherical surface and connected to the conductive ring.

In the second embodiment, the circuit contains a dielectric section, and the throttle device is placed in it and connected to one of the high-voltage electrodes, made in the form of a spherical surface.

FIG. 1 shows a refrigeration unit; general view; in fig. 2 shows an embodiment of high voltage electrodes; in fig. 3 variant of using a choke device as a high voltage electrode.

Refrigeration unit contains compressor 1, condenser 2 of high temperature fraction, heat exchanger regenerator 3 of high temperature fraction, throttle regulating 395 devices 4 and 5, evaporator 6 of high temperature fraction, heat insulated high temperature chamber 7. separation column 8, condenser 9 of low temperature fraction, evaporator. 10 low-temperature fraction, heat exchanger-regenerator 11 low-temperature fraction, heat-insulated low-temperature chamber 12, dielectric section 13, current-conducting ring 1, current-collecting grid 15, storage generator 16, dielectric inserts 1 7 and grounded electrodes 18. The refrigeration unit works as follows. Compressor 1 sucks low pressure vapors of low and high temperature iractions and pumps them into condenser 2, where vapors of the high temperature fraction are reduced. The resulting liquid is separated in the column 8 and flows through the heat exchanger-regenerator 3 and the throttle device into the evaporator 6, where it boils at low pressure, producing a cooling effect, while cooling the food in the chamber 7. The low-temperature vapor from the separation column 8 enters the condenser 9, from which the forming liquid enters through the heat exchanger-regenerator 11 and the choke device 5 into the evaporator 10, where it boils at low pressure, cooling the food products in the chamber 12. Cold The low-pressure high-temperature fraction of the vapor before suction into the compressor 1 is used to liquefy in the condenser 9 high-pressure vapor of the low-temperature fraction, and the cold low-temperature vapor is used to supercool In the heat exchanger-regenerator 3 liquid high-temperature fraction. During operation of the refrigeration unit in the first embodiment, the refrigerant, the passage through the throttle devices 4 and 5 and the energy of the differential between the condensing pressure and the evaporation pressure is triggered, acquires an electrostatic charge, which is stored in the dielectric section 13.

Claims (2)

Refrigerant through the current collection network 2. Refrigeration unit, 15 provides its charge, which through a circulating circuit for the cooling conductor ring is transferred to the agent, in which the accumulator is installed on one of the high-voltage regulating device and the electrode electrodes, which is a vaporizer located inside the heat-storage surface -generator 16. When charges are accumulated and, creating a charge intensity, the latter begin to flow onto the grounded electrode 18, thus ionizing the air gap. Due to this, air ions accumulate in chambers 7 and 12, which have a beneficial effect on stored products, increasing the duration of their storage without additional energy costs for the operation of the refrigeration unit. In the second variant of the refrigeration unit, when using a throttle device or 5 as a high-voltage electrode, electric charges are removed from the throttle device 4 or 5 and accumulated on the spherical surface of storage generator 1b, and then transferred to the grounded electrode 18. The economic efficiency of the invention lies in increasing the storage efficiency of products, significantly reducing weight loss with / increasing storage time. In addition, the creation of an ionized medium in a cooled room allows one to move to higher storage temperatures of the products and thereby reduce the specific energy costs for the operation of refrigeration units.
