Desiccant Application Humidity Control Concept
Desiccant Wheel Humidified Exhaust Air Humidity Control Concept Outside Air -------------------------------------------------- Dehumidified Air into CleanRoom Humidified Room Air
Desiccant • Advantages • It can be used for very low • Room Dew Point Temp < 4 deg C • It can be used to achieve RH < 10% • Disadvantages • High Power Consumption due to Heating • Element. • Steps control and not analog. • High Maintenance Cost. Need to change • filter and Desiccant. • Loose Desiccant can contaminate the supply air . • 5. Need big floor space. Humidity Control Concept

Psychometric Explaination Outdoor Condition Cooling Humidity Control Concept Heating Room Condition
DX Coils • Advantages • Uses Energy Recovery. Very little energy wasted. • VSD control. Analog Control. • Most cost effective to control RH above 30%. • Low Maintenance Cost. Wash the coil with water. • No contamination to supply air due to no direct • contact media. • 6. DX coils is build into the AHU. Need less space. • Disadvantages • Limitations to control RH below 30% RH due to • minimum suction gas temp of 3 deg C. Humidity Control Concept
ITS SOUND SIMPLE BUT ALL THIS THINGS IS NOT COMPLETE WITHOUT TOTAL CONTROL Humidity Control Concept
Conventional Air Conditioner & Desiccant Control • Room RH Sensor Activate when RH above 55%. • Signal send to DDC. • Activate to ON the Desiccant Unit. 3 stages heater • in Desiccant Unit fully ON. • RH of Room Drops to 50%. Then , 1 stage heater OFF. • Once RH drops below 45% , 3 stages heater OFF. • Once RH above 55% , 3 stages heater ON again. • This system uses STEP CONTROL and NOT • ANALOG CONTROL. • MOST IMPORTANTLY Control DEHUMI- • DIFICATION & COOLING SEPARATELY.
