I am Chinese so I am slow in learning software. I try to describe my problem clearly. I set up an employee dormitory as a thermal zone and turn on the ideal air loads,set cooling thermostat schedule is 23 constantly and 20 for heating. Using the open studio. However, during certain time periods in summer, the indoor temperature > outdoor temperature >23. At this time, the refrigeration power is 0, that is, the air conditioner does not work. The image is in this link because I can't upload the image yet https://drive.google.com/drive/folder... The four values in the "csv" from left to right are outdoor temperature,indoor temperature,Zone Ideal Loads Zone Total Cooling Energy,Zone Ideal Loads Zone Sensible Cooling Rate.Or you can view it in "in.csv" under the "run" file this is the file (https://drive.google.com/drive/folder...) error displayed that "The Zone is not fully enclosed",is it the reason? please help me(•̩̩̩̩_•̩̩̩̩) thank you sincerely

The outdoor temperature does not affect the operation of your cooling system. Cooling is activated only when the zone temperature exceeds your thermostat setpoint. Your thermostat schedules are not consistently set to 23°C. Instead, you use schedules with priotities, with specific settings for weekends: on Saturdays, the thermostat is set to 24°C with a setback of 26.7°C, while on Sundays, it is set to 26.7°C. Since June 3rd and 4th fall on Saturday and Sunday, respectively, these schedule differences explain the observed temperatures.

Could you also upload the OpenStudio (.osm) or EnergyPlus (.idf) models to the Google Drive?
