In embodiments of the invention, the control system that the upper and lower blower fan of heat exchanger is automatically confirmed that, including compressor 1, gas-liquid point
From device 2, indoor fan 3, throttle part 4, heat exchange temperature sensor 5, heat exchanger 6, the first blower fan 7 and the second blower fan 8, heat exchange
Device temperature sensor 5 is arranged on the bottom position of heat exchanger 6 (may also be arranged on the top of heat exchanger 6)；In the present embodiment when
Preceding environment temperature T4 is 20 degree, and a2 is that 0.5, b2 is that 5, a1 is that 7, b1 is that 300, b is 3 minutes, and Preset Time B is 5 minutes；Machine
Upper electricity, judges that blower fan position is unconfirmed, it is necessary to start blower fan location determination program, the first blower fan, the second blower fan are all with highest wind
750 revs/min of operations of speed, run to outdoor heat exchanger temperature and are approached with environment temperature, and | T3-T4 |≤3 (can also take other values
Between 1~5, then when heat exchange temperature T3 is between 17~23 DEG C, the first blower fan, the second fan parking), then shut down the first wind
Machine and the second blower fan, open compressor and open the first blower fan simultaneously, and the first fan operation rotating speed is 400 revs/min, indoor fan
It is shutdown, the rotating speed of indoor fan is zero, after running 5 minutes, record T31 values are 30 DEG C；Stop compressor, the first blower fan；Again
First, second blower fan is opened all with the operation of 750 revs/min of maximum speed, | T3-T4 |≤3 DEG C are run to always, stop first,
Second blower fan；Compressor, the second blower fan are then turned on, the second fan operation rotating speed is 400 revs/min, the rotating speed of indoor fan
It is zero, runs 5 minutes, record T32 values is 39 DEG C, | T31-T32 |=(15=0.5*20+5, the △ T3=of | 30-39 |=9 ＜ 15
0.5*20+5=15) thus the first fan and the second fan can not be identified which is fan, which is lower blower fan；Continue
Repeating first, second blower fan of unlatching makes | T3-T4 |≤3 DEG C, then blowing-out machine, and opening compressor, the first blower fan, indoor set increases by one
For example low wind shelves of shelves rotating speed, it is 8 minutes that run time is lengthened, and T31=35 DEG C is recorded afterwards, stops compressor, the first blower fan, indoor wind
Machine；Opening first, second blower fan makes | T3-T4 |≤3 DEG C, stops the one the second blower fans, opens compressor, the second blower fan, indoor set
Low wind shelves are opened, is run 8 minutes, record T32=52 DEG C, stopped compressor, the second blower fan, indoor fan and calculate, | T31-T32 |=|
35-52 |=17 ＞ 15, it is possible to determine that the position of upper and lower blower fan, T32 ＞ T31, then can show that the first blower fan leans on evaporator temperature
Sensing station is near, and the first blower fan is lower blower fan below；Second blower fan is distant from evaporator temperature sensor, is windward
