Heilongjiang provincial standard
Conversion method, the standard conditions for the precipitation rate of 5% (20% ~ Qiao%), hot air temperature of 93 ℃, ambient temperature 20 ℃, 60% relative humidity, conversion method is relatively simple.
In addition, it also considered the indirect heating of the hot air stove and the direct heating and cooling of the furnace.
