RDF Cooling air china cooler used for factory

Data for air exchange frequency in various places. Air exchange frequency(times/h)=total air flow rate(m3/h) ÷ indoor space volume. 20~30 times per hour for general environment; 30~40 times per hour for crowded public place; 40~50 times per hour for workshop with heating equipment; 50~60 times per hour for workshop with high temperature and high air pollution; Air exchange frequency can be increased in damp areas, and decreased in dry places. The way to calculate the cooler quantity needed. Cooler quantity needed = indoor space volume × air exchange frequency ÷ cooler air flow rate. Spot cooling projects shall varies based on actual situation. The ducting system shall be matched with the air cooler model, and air outlet quantity shall be considered when designing.
