When the temperature rises from two equipment factors believed to be inadequate vent.The reason is that different equipment compared to the two big exits and entrances of the temperature difference between the equipment
Factors temperature rise in the two equipment is estimated to be insufficient vent. The reason is that only the larger the temperature difference between the inlet and outlet of two equipment compared to other equipment
all the equipment in the temperature rise due to the factors vent presumption. the reason for this is, compared with the other equipment, the equipment and the two as the temperature difference is big
