Air conditioning and ventilation system design of a laboratory

Presents the design parameters of the laboratory and the design of air conditioning, ventilation and control systems. Details the design requirements of fume hood exhaust air systems and variable air volume air conditioning units used in laboratories. In the laboratory, the fans are controlled in frequency conversion by the automatic system to satisfy the operating requirements based on the quantity of operating fume hoods and the opening of regulating door, and the variable air volume air conditioning units are controlled in frequency conversion by the automatic system to meet the demands of compensating air volume based on the exhaust air volume of fume hoods.
