Design and Analyses of Industrial HVAC Systems for Variable Electricity Prices Using Fuzzy Logic

The use Heating Ventilation and Air Conditioning Systems in industries have witness an increase in past decade with the increase in number of industries Erected in the regions which tend to have hot summers and cold winters. These HVAC systems consumes about of 45% of the total industrial energy so it is thus necessary to have such smart systems which control these HVAC systems in such a way that they shed the Load from High peak Duration to medium and low peak hours without compromising Human comfort. The currently used Programmable Communicating Thermostats are capable of shifting the load form High peak to low and medium peak but they do not take into account the user satisfaction. Moreover shifting the load from High peak to low and medium peak causes an increase in Peak to Average Ratio (PAR) which is not desirable. So the Fuzzy Logic Incorporation to the existing PCT’s provides the remedy to the above addressed problems. Mat Lab/Simulink Simulation software is used in this paper to create a Real time Simulation environment of Fuzzy Incorporated PCT’s and the results are discussed for Variable electricity prices.
