Control Strategies to Conserve Energy in All-Air Heating Ventilation and Air Conditioning Systems

摘要

Commercial and residential buildings consume approximately thirty-seven percent of the energy used in the United States. Heating ventilation and air conditioning (HVAC) for these buildings requires one-half to two-thirds of this energy. Energy required for HVAC systems can be reduced by improving the HVAC control systems in existing buildings. Six typical all-air HVAC systems are considered in this report. The various control methods that are being applied to these systems are discussed. Results of work in this area by others is summarized. This report contains an extensive bibliography. Control system improvement saves energy in most applications with little or no loss of comfort. (Author)
