Product Description Working Principle When hot/cold water or stream passes the equipment, the efficient heat exchanger in the equipment is used to achieve rapid heating/cooling of the air. The large wind pressure axial flow fan installed on the top is used to forcedly press the hot/cold air down. Then the air is subject to pressure boost twice through the silencer sponge and the lower trapezoidal convergence, swirls out from the nozzle through the guide vane and is distributed throughout the space from top to down. Features By adjusting wind speed and air outlet angle, it achieves comfortable cooling or heating environment Supply air angle stepless regulation Utilize axial fan to efficiently recover heat from the top space, reducing heat/cool loss from the roof, achieving energy-saving effects The fan is installed below the air exchanger to control noise level (<60 dB) The special designed square-shaped type air exchanger prevent the leakage of condensate water The complex designed air exchanger, 1.5 times exchange area than others, takes significant heating efficiency Long air supply distance, high hot/cold air volume 4 sides return air structure, installed on the roof, require smaller installation space Function: cooling, heating Technical Comparison AirTS top heating and cooling units High and large space air conditioner lifted on the roof It achieves heating /cooling air from the air exchanger in the equipment It distributes the hot /cold air by means of efficient air distributor, which eliminates the undesirable indoor temp layers Comfortable heating / cooling environment without wind feeling sense Bottom heating unit In high large space with great depth, using radiator can allow natural air convection as hot air rises It can only radiate into small area with the range less than 5m. The heat rising to the roof will be dissipated and the temp cannot be achieved effectively in the middle area. Radiator heating requires high requirements for supply water temp. AirTS units temp field Our heating units forcedly and quickly send the hot air down, make the temp in the working area rise rapidly. Radiator heating temp field It can be seen from the radiator heating temp field image that the heat is mainly gathered on the roof and the temperature is low in the lower working area.
