A Novel Control Algorithm for Regulating the Tinting of Electrochromic Windows

A controller mechanism in conjunction with the tinting properties of electrochromic windows can reduce the environmental impact caused by energy consumption of air conditioning systems. By testing specific parameters, an algorithm was developed to regulate the tint of the electrochromic window and implemented to test its efficiency. To calculate the efficiency of the program, a simulation environment was constructed using a water cooling system for air conditioning to compute heat transfer with and without the electrochromic window-control program combination. The electrochromic window with the invented control program greatly reduced the energy expenditure by 52.7%, from 4.221 kW to 1.993 kW.
