HOW TO CONTROL HUMIDITY WITH HVAC? The standard ASHRAE design temperature is 75F and 50% relative humidity, although lower space temperatures are often preferred. A humidity controller (dehumidistat) should be used to measure room humidity levels and provide a control signal to the HVAC equipment when dehumidification is required. This is normally recommended when humidity is at or above 55%- 60% relative humidity.
One way Total Comfort Solutions helps our partners to control building infiltration is to offset outdoor air intentionally brought into the building from the exhaust air. Preventive Maintenance on key parts like dehumidistats are often improperly performed or completely neglected by many facility managers. This lack of proper maintenance, including regular cleaning, can cause major issues that can significantly increase the humidity levels and decrease the lifespan, reliability, and efficiency of the equipment. The direct consequence from not conducting PM can result in serious discomfort and financial impacts on the business. It can even affect the health of those within and around the facility.
