1) The work flow of the air supply and return air system of the evaporative cooling air-conditioning unit is as follows:

(1) Cooling mode:

Water system workflow:

In the tubular indirect evaporative cooler 25, the water in the circulating water tank a4 is transported by the water pump a3 to the water distributor a17 for spraying, and a uniform water film is formed on the surface of the heat exchange tube group 6 of the tubular indirect evaporative cooler. Heat and moisture exchange occurs in contact with the secondary air, and indirect heat exchange with the primary air in the tube, and finally falls into the circulating water tank a4 under the action of gravity, and the cycle is repeated.

In the direct evaporative cooler 27, the circulating water in the circulating water tank b12 is transported to the water distributor b23 by the water pump b10 for spraying, and a uniform water film is formed on the surface of the filler 13, and heat and moisture exchange occurs in contact with the primary air. Under the action, it falls into the circulating water tank b12 and goes back and forth.

b. Two-stage indirect and direct three-stage evaporative cooling air treatment process:

The auxiliary cold source 20 sends high-temperature cold water to the surface cooler 9 in the evaporative cooling high-temperature chiller. After the outdoor fresh air is cooled by the tube-type indirect evaporative cooler 25, it is mixed with part of the return air and enters the surface cooler 26 to wait for the humidity again. Cool down, and finally through the direct evaporative cooler 27 isenthalpy cooling process to the air supply state point, sent to the air-conditioning area 33 by the blower 15, to meet the air-conditioning requirements.

The return air returns to the return air area 40 in the unit shell along the return air duct G2 of the air conditioning area, part of the return air is sent to the air conditioning area 33 for recycling, and the other part enters the pipe-type indirect evaporation through the louver damper 8 at the lower part of the return air area 40 The cooler 25, together with the outdoor fresh air entering from the secondary air inlet 5, serves as the secondary air of the tubular indirect evaporative cooler 25, and performs heat and moisture exchange with the water film on the surface of the heat exchange tube group 6 of the tubular indirect evaporative cooler, After cooling and humidifying, it is sent to the inlet and outlet R of the air-conditioning area along the secondary exhaust pipe G1 under the action of the secondary fan 18 to be used as an air curtain 41 to prevent outdoor high-temperature air from entering the air-conditioning area.

c. Air treatment process of indirect and surface cooling dehumidification:

(2) Heating mode:

Water system process:

The fresh air in the heat exchange tube exchanges heat with the return air outside the heat exchange tube. Part of the return air is mixed and enters the surface cooler 9 to exchange heat with the air-conditioned hot water in the surface cooler 9. After being heated, it enters the direct evaporative cooler 27, where it exchanges heat and moisture with the water film on the surface of the filler 13.

3) Working process of air conditioning cold and hot water system:

During heating in winter, the hot water produced by the solar water heater 21 is transferred to the surface cooler 9 after heat exchange by the heat exchanger 22 to be used as hot water for air conditioning; when the hot water produced by the solar water heater 21 is abundant, the surplus part can be used as domestic hot water In rainy and snowy weather, when the hot water produced by the solar water heater 21 is insufficient, the auxiliary heat source 20 can cooperate to deliver air-conditioned hot water to the surface cooler 9.

In the cooling season, when the tube-type indirect evaporative cooler 25 and the direct evaporative cooler 27 of the evaporative cooling air-conditioning unit alone cannot meet the temperature and humidity requirements of the air-conditioning area 33, the auxiliary cold source 20 sends cold water to the surface cooler 9, further Cooling and supplying air to meet air conditioning requirements.

4) The working process of the rainwater collection and replenishment system of the evaporative cooling air-conditioning unit:

The upper limit value of the concentration monitored by the carbon dioxide monitor is Cs, the rated value for normal operation is Ce, and the lower limit value is Cx.

When the carbon dioxide concentration in the air-conditioning area 33 is higher than the upper limit value Cs, the louver air valve 8 is automatically opened, and a large amount of return air enters the tubular indirect evaporative cooler 25, and is exhausted by the secondary fan 18 after heat exchange. The pipe is transported to the air curtain 41 at the inlet and outlet R of the air-conditioning area, so that the fresh air volume is automatically increased, and the carbon dioxide concentration in the air-conditioning area 33 is reduced. A new return air ratio is used to supply air to the air-conditioning area 33;
