WHAT KIND OF INSUFFICIENCIES HAVE BREEZAIR AND CONVAIR AIR COOLERS?
There are some of them. First: The air coolers of evaporative type are effectively operating under the condition that relative humidity of outside air is not more than 70 – 80%. If the relative humidity is overcoming this level the air coolers must be switched to the mode of operation as simple ventilators. However in the regions with high relative humidity the comfortable conditions in the premises can be achieved even when the relative humidity reaches 80-100% by installation of bigger number of our air coolers which give the possibility to increase the number of changes of air in the premises even up to 60 times/h. Second : In winter time when the temperature outside is below 0 and there is a risk of water freezing the evaporative air coolers must be switched off from the water supply and turned to the mode of operation like usual ventilators. As the result the evaporative air coolers cannot fulfill its function as air coolers (though operating as normal ventilators they will delive
