Design of ventilation and air conditioning system for a laboratory of a chemical laboratory building

This paper presents the refined design scheme of the ventilation and air conditioning system for the laboratory of the chemical laboratory building in a university. This paper provides the design scheme of the exhaust system and the calculation result of the exhaust air rate, summarizes the advantages of the design, presents the design of the make-up air system and the laboratory ventilation control system, and gives the precise control points. When the make-up air needs to be reheated, the selection and operation strategy of air conditioning cold and heat sources are analysed.
