Air conditioning

full open window is best to quicky change air (but keep room temperatures) best at winter at 14 - 15:30 p.m

 

slightly open window is best to exchange room temperature but keep air (no ventilation) best at summer around 20 pm - 8 a.m.

explanation: gradualy reducing temperature outside is always synchronized with temeperature outside over night.
