Abstract
We surveyed the usage of air conditioner in living rooms and bedrooms to study the relationship between thermal environment and the occurrence of air conditioner On control. Then, a thermal environment control behavior model was developed with the survey results. Moreover, it was incorporated into the model we proposed before to estimate air conditioning energy consumption with the influence of cross ventilation. Finally, we studied the difference between the results calculated using typical method and our method. The results are as follow: (1) The average temperature at the time of On control in the morning and before bedtime is about 1.2℃ lower than that of daytime and evening during cooling season, while in the morning it is about 2.5℃ lower than that of daytime, evening and before bedtime during heating season. (2) The average temperature at the time of On control at night is about 1.0℃ lower than that in the morning and before bedtime and about 2.0℃ lower than that of daytime and evening during cooling season. (3) Our method estimates air conditioning duration to be about 20% less and air conditioning energy consumption to be about 8% less compared to typical method.
