Study on Residents' Behavior of Using Air Conditioners in Bedrooms in Jiangsu, Zhejiang and Shanghai
Journal: Architecture Engineering and Science DOI: 10.32629/aes.v3i1.672
Abstract
Jiangsu, Zhejiang and Shanghai are characterized with the subtropical monsoon climate, which is sultry in summer and cold in winter. Most residents use air conditioners during summer and winter because of their uncomfortable environment. The bedroom is the venue where people spend the most time. In this paper, by monitoring the environment data in the bedroom, people's behavior of using air conditioners is inferred. Finally, it is found that there are three "intermittent" energy consumption modes for the bedroom air conditioner in this area: "Turn on before going to bed" and "Turn off before going to bed", "Turn off at regular time after going to bed" and "Turn off after getting up in the morning". The simulation result of actual behavioral energy consumption is more energy saving than predicted in the standard specification. The setting temperature of air conditioners is mostly higher than the standard 26°C in summer; mostly higher than 18°C in winter. There is an obvious difference between the resident tolerance temperature and the setting temperature. After the air conditioners is turned off, the indoor environment is still in a state that residents can tolerate for a period of time. Therefore, residents who turn off the air conditioners after getting up in the morning can consider turning off the air conditioners before getting up to further save energy.
