Assuming that regional atmospheric pressure is 101.325kPa, total air output is 20000m3/ h, total volume of return air 14000m3/ h, newly
Wind ratio a=30%, reference temperature range value X required by production technology01~X02It is 20 DEG C ~ 24 DEG C, required benchmark is relatively wet
Spend value range Y01~Y02It is 50% ~ 60%, looks into its corresponding benchmark absolute humidity value range Z known to humid air psychrometric chart01~Z02For
7.26g/m3~11.19g/m3, system heat load makes return air temperature X2Relative to supply air temperature X3Temperature gap be b=X2−X3=
2 DEG C, system humidity load makes return air absolute humidity Z2Relative to air-supply absolute humidity Z3Difference be c=Z2−Z3=0.3g/m3。
1. as fresh air temperature value X1=20 DEG C, fresh air rh value Y1When=70%, its correspondence known to humid air psychrometric chart is looked into
Fresh air absolute humidity values Z1=10.214g/m3, by X1、Z1, a, b and c substitute into following formula operation reference value X and Z, obtain：
X=(aX1+b) ⁄a=(30%×20+2)/30%≈26.67(℃)；
Z=(aZ1+c)∕a=(30%×10.21+0.3)/30%≈ 11.21(g/m3)；
Due to Z=11.21>Z02=11.19, then choose X02=24 DEG C are used as desired temperature, choose Y02=60% is used as relative humidity

Temperature is 21.3 DEG C after mixing, and rear surface cooling water blocking section does not work, and need to be heated to 22 DEG C of air-supplies in steam heating segment, pass through humid air
Its consumed energy about 24000kj/h is known in psychrometric chart operation, and wastage in bulk or weight energy is about 60000kj/h（Ignore fan energy consumption）.
If according to the method for existing artificial setting humiture setting value, such as controlled ambient temperature and humidity setting value is set respectively
When being set to 20 DEG C and 50%, automatic control air-conditioning system 2 to be made to reach setting value equilibrium state, preceding surface air cooler and manger board segment is needed new
Wind-warm syndrome angle value drops to about 8 DEG C（Relative humidity at this time is about 95%）, energy consumed by it is known by humid air psychrometric chart operation
About 147600kj/h, temperature is 16.4 DEG C after mixing 8 DEG C of fresh airs with 20 DEG C of return air in new air-return mixing section, rear surface cooling gear

Fresh air absolute humidity values Z1=7.34g/m3, by X1、Z1, a, b and c substitute into following formula operation reference value X and Z, obtain：
X=(aX1+b) ⁄a=(30%×16+2)/30%≈22.67(℃)；
Z=(aZ1+c)∕a=(30%×7.34+0.3)/30%≈8.34(g/m3)；
Due to Z01=7.26<Z=8.34<Z02=11.19, then absolute humidity Z corresponds to relative humidity Y01Temperature X0It is 22.2 DEG C, it is right
Answer relative humidity Y02Temperature X2It is 19.3 DEG C, then relative to value range [X2,X0], X0It is closer with reference value X, therefore by temperature
