The air form is sent on the next time, the outlet diffuser for the square duct design and hydraulic calculations assume that the flow rate; cold and heat source in the mall underground negative layer, select the centrifugal unit, and then choose cooling tower and air-conditioning units, auxiliary eq

Supply air is sent back on the air inlet Square, heat flow, assuming that the flow rate of air duct to the design and hydraulic calculations; cold heat design for the underground shopping arcade in a layer, select centrifugal units, cooling tower and before you use auxiliary equipment, air condition

The blast form will be on delivers the next time, the supply-air outlet drifts for the square shape, has carried on the design and the water power computation with the hypothesis speed of flow law to the air hose; The cold heat source design in market underground -1, the choice centrifugal type unit

On air is sent back, air outlet for square diffusers, assuming that velocity in hydraulic calculation and design of air duct by; underground layer of cold heat source design in shopping centres, selecting centrifugal chiller, selection of cooling towers and air conditioning unit auxiliary equipment,
