Correction Coefficient DT1:
The cooling capacity in the sample=return air temperature - evaporation temperature, based on the refrigerant R-404A, parameters under direct expansion DT1 and 85% RH operating conditions.
DT1 is the difference between the return air temperature of the studio air cooler and the evaporation temperature.
Evaporation temperature refers to the saturated gas temperature of the refrigerant at the outlet of the cooling fan.
Nominal Cooling Capacity:
（ACA）t0=0° and DT1=10K
（ACB）t0=-8° and DT1=8K
（ACC）t0=-25° and DT1=7K
The correction coefficient varies based on changes in return air temperature and temperature difference, please refer to the table below to find the corresponding correction coefficients.
Actual cooling capacity before selection it must be multiplied by the corresponding correction factor in the table below.
Obtained nominal cooling capacity only in the attached selection table can it be shaped.
Q nominal=correction factor × Q actual cooling capacity
Calculation Examples：
Fin Spacing :
6 mm - DT1 =+3-(+10)= 7K Required
Capacity :
30 KW - Correction factor = 1,54 Air-on
Temperature :
+10℃ - Multiply tequired capacity
Refrigeration Temp :
+3℃ With vorrection factor
Condition :
SC1 30 KW×1,54= 46,2 KW
Refrigerant :
R-404A - Select air cooler from the talbe
(ACC type VCI-B 63506=47,5 KW)
