Design parameters of fresh air for users in summer: in order to improve the stability of the system, the outdoor design parameters are taken as the parameters of bad working conditions, the dry bulb temperature is 35 ℃, the relative wet bulb temperature is 75%, and the absolute moisture content is 27g / kg; 3.2. System load: light labor intensity produces heat (80-100w/h. person); the comprehensive heat load of the enclosure structure is calculated at 60-110 w/m2 according to the system layout and indoor heat source, with a height correction factor of 2%, equipment The heat load is calculated by 10%-20% of the installed power according to the type; 3.3. Humidity production: when the temperature is 23℃, the humidity production of personnel with light labor intensity is (80-100g/h.person); the ventilation and humidity load of the air-conditioned room is calculated according to the air-conditioning room's 0.1-0.2 air exchange permeability; return air The moisture penetration load is calculated based on the return air volume 1%-3% of the ventilation penetration volume; the ventilation moisture load of the low-humidity dry room is calculated based on the moisture production volume of 2-5g/m2 in the air-conditioned room; 3.4. System air volume: fresh air volume (20-50m3/h. person) and maintaining positive pressure in the room require 5-10 Pa in the drying room; ensure the humidity gradient of the drying system. 4.
