Cooling Effect





Annual Cooling Effect

Excelair always propose that workers should work in a comfortable environment for increasing productivity. As the right chart shows, workers will work in the heat stress environment when the temperature of workspace reach to 31 .    According to the temperature data of three big cities in china offered by China weather bureau in 2008, the temperature of most cities in china will be higher than 31 for more than half the time during the year, which undoubtedly will cause malaise to workers.   
Heat Stress and Comfort

City Temperature Analysis
Highest Temperature   Relative Humidity 
The highest outside air temperature oC likely to reach during the specific month The relative humidity (%) of the outside air corresponding to the Highest Temperature.
Supply Air Temperature Dew Point 
The temperature oC of the supply air at the air diffuser when Open Space Cooling system is used.  
The temperature oC of the supply air at the air diffuser when Open Space Cooling system is used.
2008 Three cities weather data 
Highest Temperature   RH    Supply Air Temperature   Dew Point


The above data shows that the temperature in three big cities is in heat stress zone or even in severe heat stress zone for months. The thermal radiations will maker the temperature in the factory even higher. Anyway, with open space cooling, the inside temperature of factory will stay in the heat comfort zone. 

Will the temperature of supply air create undesirable effects on product/equipments? 
No, because the supply air temperature will not reach the dew point temperature which is the temperature where water droplets begin to form.
