Measurement and analysis of air-conditioning-usage behavior in apartments

Taking six apartments in Beijing as examples, based on the continuous measurement of indoor air temperature and humidity and the relevant questionnaires investigation, discusses air-conditioning-usage behavior from the three aspects of open, close and running time, and compares air-conditioning-usage behavior in different activity and rest conditions. The results show that there may not exist a strict single control relation between the open or close behavior of air conditioners and the indoor environment conditions especially indoor temperature, and that occupants may not necessarily turn on air conditioners even when indoor air temperature rises over 29 ℃ and turn off air conditioners when room temperatures drops under 26 ℃ due to the coaction of indoor environment and physical and psychological components; air-conditioning-usage behavior will depend on occupants’ thermal sensation and the expectation for the indoor thermal and humid environment.
