Description

This invention relates to air conditioning systems.

The purpose of the invention is to reduce energy costs for cooling air and drying it.

The drawing shows a device for heat and moisture treatment of air.

The device for heat and humidity air treatment contains an irrigation chamber 1 with a pallet 2 located in chamber 1 two rows of racks 3 with nozzles 4 facing one another and a nozzle 5 placed between them, the pallet 2 being divided by a partition b into compartments 7 and 8 warm and cold water, and the first along the course of the air flow 3 is connected via pipe 9 with pump 10 to the compartment of cold water, and at the outlet of the irrigation chamber 1 a heat exchanger 11 is installed.

The device is equipped with a heat exchanger 12 installed in front of the irrigation chamber 1, whose inlet to the coolant is connected through pump 10 to compartment 7 of warm water, and the outlet to the inlet of heat exchanger 11 installed at the outlet of irrigation chamber 1 connected to the bottom of the 3 st p Yes.

The inlet of the heat exchanger 12 is connected to the pipeline 9 and to the discharge side of the pump 10 by the pipeline 13, and the outlet to the pipeline 14, through the regulator 15 with the heat exchanger 11. At the outlet of the irrigation chamber 1, a separator 16 is installed in front of the heat exchanger 11.

The heat exchanger 11 is connected by pipe 17 to the lower part of the stoves 3 of the first row through a check valve 18.

The pump 10 is connected with the compartment 7 of the heated water through the stop valve 19, the pipe 20 and the filter 21. In addition, the pump 10 is also connected with the cold water compartment 8 through the stop valve 22, the pipe 23 and the filter 24. The pipe 9 is connected to the drain 3 second row through the check valve 25, the valve body 26 and the pipeline 27 with a regulating valve 28.

The sensor 29 of the regulating valve 28, connected to the regulator 30, is installed after the irrigation chamber 1, and the sensor 31, connected to the regulator 32 of the regulating valve 15, is installed behind the heat exchanger 11. In the compartments 7 and 8 of the pallet 2 there are overflows 33 and 34, Overflow 33 of the heated water compartment 7 through the stop valve 35, and the overflow 34 of the cold water compartment through the stop valve 36 are connected to the pipelines of the refrigeration station. In the pan 2 is installed ball valve 37.

Device for heat and humidity air treatment works as follows.

In summer, the device operates in the mode of cooling and dehumidifying the air in the heat exchanger 11. The coolant from the refrigeration station is fed to the second row of stations 3 by the signal from the electronic controller 29. After spraying, water is collected in the cold water compartment 8 of the pallet 2, and then overflow 34 is directed to the refrigeration station.

From the compartment 7 of the heated water of the pallet 2, the water is taken by the pump 10, then the pipe 5 is fed to the first row of racks 3, and also through the pipeline 13 through the heat exchanger 12, through the pipeline 14 through the heat exchanger 11, through the pipeline 17 into the lower part of the first Yes and no. 3. The cold water supply unit 22 to the pump 10 and the water supply to the refrigeration station 35 are closed in this mode of drying and cooling the air.

The circulation of water through the heat exchangers 12 and 11 in the compartment 7 of the heated water is carried out by the pump 10, the flow of which is controlled by the regulator 32, which acts on the valve 15 depending on the temperature of the intake air measured 0 by the sensor 31.

The required amount of water sprayed by the drains 3 of the second row is controlled by the controller 30, which acts on the valve 28 when the temperature of the conditioned air deviates from the dew point temperature measured by the sensor 29.

In the compartment 7 of the heated water of the pallet 2 of the irrigation chamber 1, the water has a higher temperature than the temperature of the dew point 0 of the air leaving the chamber 1, and the passage through the heat exchanger 12 is heated by the heat of the outside air and then in the heat exchanger 11 heats air. The cooled water after 5 of the heat exchanger 11 through the pipeline 17 returns to the first row of tanks 3. In winter, the heat exchanger 11 is turned off, the evaporation of air is heated in the irrigation chamber 1, 0 The heated water is supplied by the pipeline 27 to the second row of stands 3, After spraying water is collected in compartment 8, then pump 10 is supplied to the first row of sewers 3. In winter, the stop valve 19 supplying water from compartment 7 to pump 10 and the stop valve 36 of overflow 34 from compartment 8 are closed. After spraying with sprays 4 of the first row, water is collected in compartment 7 and directed through an overflow device 33 to a low potential heat source.

The air passing through the irrigation chamber 1 is heated to the dew point temperature, and then in the usual way in the second preheater heaters or in the zone preheaters.

The use of the heat exchanger 12 to the irrigation chamber 1 in the proposed device of the thermal-humid air treatment allows one to reduce the consumption of cold by 0.5 kcal per 1 kg of the treated air (or by 10%).
