Description

The invention relates to refrigeration equipment, namely, air coolers with oro, chillers for defrosting heat transfer surfaces.

The purpose of the invention is to improve the performance and quality of the air cooler by increasing the intensity of cooling, the effectiveness of thawing and the provision of electro-antiseptic cooling air.

FIG. 1 shows schematically the proposed air cooler, general view; in fig. 2 shows a section A-A in FIG. in fig. 3 - air cooler in overhead version, general view; in fig. 4 shows a section BB in FIG. 3; in fig. 5 - air cooler in the floor version; in fig. 6 shows section B-B in FIG. five.

The air cooler is installed in the refrigerating chamber 1 and consists of a cooling battery 2 mounted on dielectric gaskets and closing the defrosting cooling battery 2 turns off the fan 11 and stops the refrigerant supply to it. Then the power supply 12 is turned on, the potential of the given polarity is applied to the high-voltage electrode 5 by means of the switch 13, and the required field strength is established between the electrodes 5 and 6. Next, the rotary valve 9 is opened and a warm cooling battery 2 is supplied through the pipeline 14. After de-icing the ice from the surface of the cooling device, the water flows into the pan 7, from where it is led out to the outside by means of the drain pipe. Forming with steam boiler on

Looped into the housing 3, which is filled 25, the mixture is suppressed electrically from the dielectric, pipelines 4 for supplying and discharging the refrigerant, high-voltage electrode 5, filled in the form of a frame with parallel tensioned wires (30 wires can serve as wires ), a grounded electrode 6, made in the form of a metal grid (the surfaces of the electrodes 6 and 5 should be slightly larger than the horizontal cross section of the cooling battery 2), the sump 7 with a pipeline to collect melt water covered with thermal insulation 8, and a rotary a damper 9, a dielectric housing 10, made, for example, 40 of Plexiglas, a fan 11 installed therein, a power source 12 equipped with a switch 13 for switching the polarity of the voltage on the electrode 5, a pipeline 14 for supplying warm water located with a slope for the flow of water, a dielectric sleeve 15 mounted on the pipe 14 for supplying warm water, and dielectric bushings 16, JQ installed on the pipes 4 for supplying and discharging refrigerant, sprinklers 17, |) placed in the upper part of the cooling battery and connected to the pipeline to supply warm jj water.

Electrodes 5 and 6 are installed in the housing 3 on both sides of the cooling

The laser is directed towards the grounded electrode and settles on the surface of the cooling battery 2. At the same time, the concentration of microorganisms in the environment decreases. Upon completion of the thawing process, the moisture particles deposited on the surface of the cooling battery 2, under the action of an electric field, are charged and coagulated, the result is that the drops are enlarged, the force of gravity increases, their surface tension decreases, and the water drops are blown off from the surface of the cooling device down onto the pan by the action of the electron wind.

After thawing the cooling battery 2, shut off the supply of warm water to the pipe 14, the water left in the sprinklers flows through the inclined pipe 14j and then shut off the drain hole with the rotary valve 9. Then the fan 11 is turned on and the refrigerant 2 is fed through the pipe 4. At this point, the surfaces of the cooling battery 2 are free of water particles, which contributes to increasing the intensity of air cooling due to a decrease in thermal resistance of the heat exchanging surfaces.

battery 2 under its most developed surface. The distance between the fan 11 and the closest to it surface of the high-voltage electrode-5 exceeds the patcTOHHHe between the electrodes 5 and 6.

The air cooler works as follows.

Before defrosting the cooling battery 2, turn off the fan 11 and stop the supply of refrigerant to it. Then the power supply 12 is turned on, the potential of the given polarity is applied to the high-voltage electrode 5 by means of the switch 13, and the required field strength is established between the electrodes 5 and 6. Next, the rotary valve 9 is opened and a warm cooling battery 2 is supplied through the pipeline 14. After de-icing the ice from the surface of the cooling device, the water flows into the pan 7, from where it is led out to the outside by means of the drain pipe. Forming with steam boiler on

the mixture is suppressed by an electric field directed toward the grounded electrode and settles on the surface of the cooling battery 2. At the same time, the concentration of microorganisms in the environment decreases. After the process of defrosting, the moisture particles deposited on the surface of the cooling battery 2 are charged by the electric field and coagulate, resulting in coarsening of the droplets, increased gravity, their surface tension decreases, and water droplets are blown off from the surface by the action of electron wind. giving the device down to the pallet.

After thawing the cooling battery 2, shut off the supply of warm water to the pipe 14, the water left in the sprinklers flows through the inclined pipe 14j and then shut off the drain hole with the rotary valve 9. Then turn on the fan 11 and feed the refrigerant to the cooling battery 2 through line 4. K At this moment, the surfaces of the cooling battery 2 are free of water particles, which contributes to increasing the intensity of air cooling due to a decrease in thermal resistance of the heat exchanging surfaces.

they do not otkatochayutsya, so the formation of ice occurs in the ionized gas flow and manifests itself in the form of filamentous snow cover, oriented vertically along the line of action of the Coulomb forces. The filaments that are formed are not easily blown off by the air flow created by the fan. what allows to increase duration of uninterrupted operation of the cooling device in the cooling mode between the periods of thawing.

To him, the surface of the high-voltage electrode more than the distance between the electrodes and the electrodes is necessary in order for the electric field to be created only between the high and low-voltage electrodes.

The proposed air cooler, in comparison with the known one, eliminates the presence of water droplets on the surfaces of the cooling battery 2 after defrosting it, which increases the cooling rate, leads to the formation of filamentous form, thereby increasing the operation of the air cooler between the defrosting periods, reducing the concentration of microorganisms and bacteria. in the treated air by means of electro-antiseptic.
