ABSTRACT
It is well known that the most effective method of air distribution in high-heat areas is displacement ventilation with a variable air loss according to changeable operating conditions. Dense equipment arrangement makes requirements to air distribution even higher. The necessity of spreading jets till they reach convective flows is shown. To slow down these jets uniform air supply is required at the exit of an air distributor. Modern devices do not fully meet this requirement. The suggested method of air supply ensures uniform air distribution and thorough ventilation of the area at a changed expenditure of inflowing air.
