At this time, the secondary air is humidified by isoenthalpy, the primary air is cooled by isothermal humidity, and the primary air is the lowest. The temperature can only reach the secondary air wet bulb temperature.

When the user's cooling capacity demand increases, the lower motor speed of the unit increases, which drives the first fan 11 to increase the speed, and the air volume increases. When the actual cooling capacity of the air-conditioning unit meets the demand value, the current speed of the motor remains unchanged and waits for the next command. When the cooling capacity keeps rising, the lower motor speed keeps rising, and the air volume keeps rising. When the wind pressure sensor 24 reports an alarm, the lower motor speed has reached the limit value, and the air volume has also reached the limit value. At this time, the wall evaporative cooler Even if it runs at the maximum air volume, the cooling capacity demand cannot be met, so the structure of the adjustable evaporative cooler is switched to the dew point evaporative cooler, that is, the baffle 23 is moved to the second state. When the structure of the adjustable evaporative cooler is switched to the dew point evaporative cooler, the side air valve 25 is closed, and part of the primary air enters the secondary air passage 221 and is converted into secondary air. The secondary air is subjected to secondary cooling treatment, and its wet bulb temperature decreases again and again, and the primary air reaches the secondary air wet bulb temperature. At this time, the temperature of the primary air is lower than the primary air temperature of the partition evaporator, which can improve the air conditioning system. cooling capacity.

Air conditioning assembly according to claim 6, characterized in that the fan section (10) comprises a first fan (11) and a second fan (12), wherein the first fan (11) is adapted to control the amount of primary air and the second fan (12) is adapted to control the amount of secondary air, and wherein

When the baffle (23) is in a first state, the side air valve (25) of the evaporative cooling section (20) is in an open state, primary air enters the primary air channel (211) from the mixing section (40), then is blown out from the first fan (11), and the primary air is subjected to equal-humidity temperature reduction treatment; after entering a secondary air channel (221) through a side air valve (25), secondary air is blown out of the second fan (12) and subjected to isenthalpic humidification treatment;

when baffle (23) are in the second state, side blast gate (25) of evaporative cooling section (20) are in the closed condition, and partial primary air that flows through primary air passageway (211) passes through first through-hole (212) and second through-hole (231) of adjustable evaporative cooler structure get into secondary air passageway (221) to convert into secondary air after making partial primary air cooling and carry out isenthalpic humidification processing once more.
