Experimental Study of Health and Energy-Saving for Air Conditioner Working in the Residential Bedroom

Based on experimental data, including CO₂ concentration, temperature, relative humidity and power consumption, tested under 4 different conditions according to the usage of residential bedroom, IAQ and the comfort of the bedroom at night is thus studied in aspect of saving energy consumption of the air conditioner. The result indicates that reasonable ventilation help air conditioner run in a healthy and energy-saving way as well as improve IAQ, that is to say, bettering indoor air environment whereas adding a little energy consumption if windows are opened, and distinctly slashing energy consumption if curtains are closed.
