Control strategies for indoor environment quality and energy efficiency—a review

Abstract

The demand for better indoor environment has led to a wide use of heating, ventilating and air conditioning (HVAC) systems. However, this demanding cannot be sustained without a strategy to reduce the energy consumption of HVAC systems. Employing advanced HVAC control is one of the strategies to maintain high-quality indoor thermal comfort with low energy consumption. This paper reviews the development of control technologies for HVAC systems. It summarizes the problems in existing reviews and gives a future perspective on HVAC control systems for occupant comfort and energy efficiency.
