The alternate operation control strategy between natural ventilation and air-conditioning considering delay time

Most research in the field of indoor thermal environment control has been devoted to search for an appropriate on/off temperature air-conditioning while relatively ignoring energy-saving effect transition period length after turned off. We proposed a model alternate operation between natural ventilation and measure delay time compared energy consumption two cooling modes (continuous alternative air-conditioning) different capacity buildings China’s hot summer warm winter areas. Furthermore, we obtain under buildings. The results indicate that with more have greater ventilation. Alternative strategy can save at least 15% continuous cooling. are helpful guide residents adjust their use habits according alleviate pressure air conditioning areas China.
