Ventilation and air conditioning system for large part numerical control machining buildings

In view of the characteristics of large space and dispersed pollutant sources of metal machining fluid, proposes a ventilation and air conditioning system scheme, i.e. stratified air conditioning plus peripheral collecting. Analyses and calculates the smog concentration in a machining building respectively on the conditions of isolated and non-isolated heavy pollution source machines, and the results prove that the effect of peripheral collecting is superior to that of centralized collecting. The effect of the scheme of stratified air conditioning plus peripheral collecting is satisfactory.
