Abstract

The invention allows to reduce energy, capital and operating costs and improve the efficiency of air treatment. The side, front and rear walls 2, 3, 4 of the housing 1 form vertical ribs. The housing 1 houses a heat exchanger 5 with supply and exhaust channels / K / 6, 7. The heat exchanger 5 is made in the form of a pack of plates that form perpendicularly directed alternating vertical channels of supply and exhaust air. The package has the shape of a parallelepiped, one vertical edge 13 which divides the plane of the wall 3 into equal parts forming the outlet and the entrance K 6, 7. The ribs 14, 15 are located in the plane of the wall 4. The atomizer 11 is placed in K 7 above the pallet 10 in front of the heat exchanger 5 with the possibility of irrigation. The baffle plate 12 is fixed on the heat exchanger 5 in K 7. The output K 7 is in communication with the inlet K 6. The plates of the heat exchanger are perforated. 2 hp ff. 1 il.

Description

The invention relates to air conditioning and can be used in the development of autonomous air conditioners for industrial, administrative and residential buildings.

The purpose of the invention is to reduce energy, capital and operating costs, as well as increase the efficiency of air treatment.

The autonomous air conditioner comprises a housing 1 with side 2, front 3 and rear 4 walls forming vertical fins, heat exchanger 5 placed in housing 1 with flow 6 and exhaust 7 channels, fans 8 and 9. The air conditioner further comprises a drip 10, spray nozzle 11 irrigated liquids and a baffle plate 12. The heat exchanger 15 is made in the form of a pack of plates that form perpendicularly directed alternating vertical channels of flow and exhaust air. The package has the shape of a parallelepiped, one vertical edge 13 of which divides the plane of the front wall 3 of the housing 1 into equal parts, forming the exit and entrance of the channels 6 and 7, and two other edges 14 and 15 are located in the plane of the back wall

4 cases 1. The atomizer 11 is placed in the exhaust channel 7 above the tray 10 in front of the heat exchanger 5 with the possibility of irrigation of the latter. The baffle plate 12 is fixed on the heat exchanger 5 in the exhaust channel 7.

The outlet of the exhaust channels 7 of the heat exchanger 5 can be communicated with the inlet of the flow channels 6.

In addition, the plate heat exchanger

5 can be made perforated.

Autonomous air conditioner works as follows.

When the fan 9 is turned on, the air from the room is supplied to the exhaust channel 7. Before entering the heat exchanger, the atomizer 11 sprays the irrigated liquid, which moistens the air. Upon contact of the air flow with the irrigated liquid, it is adiabatically cooled and the air acquires the temperature of a wet thermometer. The adiabatic cooling process takes place in the heat exchanger due to the fact that the irrigated liquid spreads through the channels. The residuals of the irrigated liquid flow into the sump 10, from where it is again supplied to the nebulizer 11. The air flow passing through the heat exchanger through the exhaust channel 7 is emitted into the atmosphere.

When the fan 8 is turned on, external air is drawn into the flow channel 6. This air, passing through the heat exchanger 5, is cooled due to the heat exchanger with the air from the room. In addition, the process of cooling the outside air can be combined with its moistening in the case of heat exchanger plates 5 with perforations.

0 It is also possible to increase the cooling efficiency if part of the heat exchanger 5 is installed below the level of the irrigated liquid in the pan 10, and also if additional corrugated plates are used.

5 between the plates of the heat exchanger.

If it is necessary to cool and humidify only the air of the room, the outlet of the heat exchanger ducts is connected to the inlet of the flow channels.

0 Compared to what is known in the autonomous conditioner of the invention, energy, capital and operating costs are reduced, and the efficiency of air treatment increases.
