Description

The invention relates to an air-conditioning technique and can be used, for example, in textile plants.

The aim of the invention is to reduce capital and operating costs.

The drawing shows a schematic diagram of the air conditioning system.

The air conditioning system, for example, in the shops of textile enterprises with heat generation and high relative humidity in the installed equipment zone, contains a central air conditioner 1 with supply air channel 2, fan 3, heat exchangers 4 and humidifier 5 connected to water supply 6 with valve 7 , air recirculation device 8 and an air humidifier 9 located in the workshop, including a heat exchanger 10, a water supply line 11 with a solenoid valve 12 communicated by a pulse line 13 with a wet-air sensor awns 14.

The system further comprises a cooling source 15 with pipes 16 and a humidity control sensor 17 located in the working area. The humidifier 5 of the central air conditioner 1 and the air humidifier 9 are made in the form of evaporative cooling apparatuses with irrigated layer, and the humidifier 5 of the central

air conditioner 1 is installed in the working area and connected by supply air channel 2 to fan 3, air humidifier 9 is located in the equipment area and communicates with air recirculation device 8, an additional humidity control sensor 17 is connected to valve 7 on the water supply system 6, and a cooling source 15 by pipes 16 is connected to heat exchangers 4 and 10 of central air conditioner 1 to an air humidifier, and the heat exchangers 4 and 10 are interconnected.

The air conditioning system operates as follows.

When the central air conditioner 1 is operated, it absorbs 20-30% of the total heat surplus from the process equipment, which makes it possible to lower its air capacity and bring it closer to the sanitary norms of the external air supply.

During the warm period of the year, water is cooled in the heat exchangers 4 of the central air conditioning unit 1, cooled in the cooling source 15, which receives heat from the fresh outside air. The cooled supply air through the supply air channel 2 enters the humidifier 5, where the passage through the layer irrigated with tap water is moistened. At the same time, the flow of water going to the layer irrigation is automatically controlled by the valve 7, which receives pulses through line 13 from the humidity control sensor 17 installed in the working area.

The main heat surpluses from the process equipment are removed by cooling the recirculated air in the heat exchangers 10, which are connected by pipes 16 with a cooling source 15. The air cooled in the recirculating device 8 is supplied to the humidifier 9, where it passes through the irrigated layer and humidified.

To the humidifier 9, water is supplied via a water line 11, to which an electromagnetic valve 12 is installed, communicated by a pulse line 13 to a humidity sensor 14. The signal from a humidity sensor 14 increases or decreases the water supply through an electromagnetic valve

12. Thus, the relative humidity of the recirculated air is regulated, which makes it possible to maintain the necessary relative humidity in the area of the process equipment.

During the cold period of the year, the warm water after the heat exchangers 10 is supplied to the heat exchangers 4 of the central air conditioner 1, which makes it possible to heat the cold intake air.

The process of humidification of the supply and recirculated air in the warm period is the same as in the cold period of the year.
