How do I maintain a specific spray temperature inside the paint booth?
I live in Malaysia with the temperature of 32 degree Celsius, how do I maintain the spray temperature of 23 degrees Celsius inside the painting booth? Do I need to install a chiller and humidifier?
Due to the conditions in Malaysia the temperature set-point being asked for is at or below the dew point in the summer months. A chiller would be required to attain that temperature, but the outside walls of the booth may form condensate if the dew point of the outside air is at or above 23°C.
Humidity is a large issue in Kuala Lumpur, Malaysia. Cooling the air would cause for other conditions such as condensate on the booth walls or a high relative humidity in the booth since the air is being cooled down to the saturation temperatures in the summertime.
Standard design practice would be to condense the moisture out of the air by sub-cooling with a chiller and then reheating the air with indirect heat to the desired operating temperature and relative humidity set-point. This practice would be done only with the use of an insulated booth with a vapor barrier in the environment of Malaysia.
