Comprehensive Analysis of AC Waste and Thermal Comfort in Indoor Environments

This study provides an in-depth examination of air conditioning (AC) waste, utilizing motion sensor data and thermal comfort parameters. It assesses the proportion of AC waste in various situations, analyzes temperature ranges, and evaluates human occupancy status across different zones and time intervals throughout the week. The findings include a breakdown of AC efficiency, energy waste occurrences, and comfort levels to enhance the management of indoor climates. The integration of machine learning techniques informs predictive models for optimizing energy use in air conditioning systems.

  1. System overview motion sensor state AC waste analysis AC state predictor proportion of AC waste AC information AC state thermal comfort calculator thermal comfort questionnaire thermal comfort range Tindoor Toutdoor NTU CSIE iAgent Lab

  2. Condition of AC • waste situation 1.mn = no and (yn = 1 or yn = 2) 2.mn = yes and yn = 2 and Tindoor < TcomfortableRange • abnormal situation 3.mn = yes and yn = 2 and Tindoor > TcomfortableRange NTU CSIE iAgent Lab

  3. 顯示(非及時) • 區域(zone) • 各種空調、有/無人狀態比例 • 三種空調浪費情況比例 (前頁) • 周一至周日每個時段(小時)的空調浪費情況次數 • 周間與周末每個時段(小時)的空調浪費情況次數 • 房間(room) • 三種空調浪費情況比例 • 1. 該房間每個區域的 mn= 0 且 至少有一區域的 yn≠0 • 2. 在 mn=1, yn=2 的區域中, 符合Tindoor<TcomfortableRange 的區域數大於等於 50% • 3. 在 mn=1, yn=2 的區域中, 符合Tindoor>TcomfortableRange 的區域數大於等於 50% • 周一至周日每個時段(小時)的空調浪費情況次數 • 周間與周末每個時段(小時)的空調浪費情況次數 NTU CSIE iAgent Lab

  5. Display (history) • zone • percentage of each state (ac, motion) during a period • percentage of each waste situation during a period (previous) • from Monday to Sunday, the count of each waste situation for each time interval (hour) • room • percentage of each waste situation during a period • 1.every zone in the room that mn= 0 and there exists at least one zone that yn≠0 • 2. within the zones (mn=1, yn=2), calculate number of the zones that conform to Tindoor<TcomfortableRange more than50%or not • 3. within the zones (mn=1, yn=2), calculate number of the zones that conform to Tindoor>TcomfortableRange more than50%or not • from Monday to Sunday, the count of each waste situation for each time interval (hour) NTU CSIE iAgent Lab
