Method for achieving energy conservation and control based on using full fresh air in transition seasons

The invention discloses a method for achieving energy conservation and control based on using full fresh air in transition seasons. The method comprises the following steps that a control module sends a detection instruction to a temperature detection module, the temperature detection module feeds back temperature information to the control module after detecting outdoor temperature, the control module sends an instruction according to an outdoor temperature numerical value, and when the outdoor temperature numerical value is higher than a preset interval, a temperature adjusting module is controlled to be started to do circulating air return indoors. The structure is compact, operation is easy and convenient, practicability is high, the outdoor temperature is detected by arranging the temperature detection module, the control module changes the operation mode according to the change of the external temperature, the energy-saving efficiency of the system is improved, a data collector collects real-time operat
