Abstract

A LABORATORY DESIGN MODEL FOR BUILDING’S H EATING, VENTILATION AND AIR CONDITIONING USING PROGRAMMABLE LOGIC CONTROLLER AND SUPERVISORY CONTROL AND DATA ACQUISITION

B.I Aldi, Dr. J.S Kadadevarmath* and N.P Bannibagi

ABSTRACT

The objective of this paper is to design and build the prototype automatic control system for Heating, Ventilation and Air conditioning (HVAC), to maintain the comfortable environmental conditions inside the building using Programmable Logic Controller (PLC). Allen Bradley Micro Logix 1100, 1763-L1BBB PLC is used for automatic control of temperature, humidity and circulation of air within the room. The system consists of an interfaced hardware module and sensors for temperature and humidity control. Compact system is designed to provide temperature range within 23°C to 26°C and humidity range within 60% to 70% RH (Relative Humidity). The PLC continuously monitors the weather conditions of Hubballi-Dharwad twin cities and controls the HVAC to get the comfort environmental conditions within the laboratory of the department of Electronics, Karnatak University, Dharwad. The relevant data are recorded by supervisory control and data acquisition (SCADA) system.
