Title

DEMAND-BASED CONTROL OF HVAC SYSTEM FOR INDOOR AIR QUALITY AND THERMAL COMFORT

Abstract

People spend most of our time in indoors. In indoors the health of the occupant is mostly affected by the indoor air quality (IAQ) and thermal condition. IAQ can be affected by microbial contaminants and gaseous pollutants. Since generation of carbon dioxide (CO2) often increases its concentrations to uncomfortable level, an occupant inside room affects mostly CO2 concentration level out of other IAQ parameters. Changes in the thermal condition inside room is mostly due to seasonal changes, however thermal comfort inside room can be achieved by desired level of temperature and relative humidity.Usually for controlling indoor air quality (IAQ) and thermal comfort inside buildings a costly heating, ventilation and air conditioning (HVAC) system is used. To achieve these comfort conditions inside single room it is not feasible to install this costly HVAC system, although to partially achieve these comfort conditions different components operating independently were used but individual operation ofthese components can’t achieve desired comfort conditions.In this paper,PC based automatic virtual instrumentation system was designed to integrate working of individual components to achieve the comfort conditions inside a room. The three indoor parameters (i.e. CO2 concentration, temperature and relative humidity) were monitored in a room online using sensors and data acquisition device and controlled through the application software implemented on LabVIEW platform. A fuzzy controller wasdesigned and implemented to control CO2 concentration and temperature and relative humidity was controlled by ON-OFF controller. Control signals were issued to vary the exhaust fan ventilation rate, heating or cooling power of the heating or cooling system installed in the room to provide desired comfort conditions along with saving of electrical energy
