New fan 100 includes casing 110, purification module 120 and fan 130 are located in casing 110, casing 110's both ends are the air inlet end 111 that is used for the air inlet respectively and are used for the air supply end 112 of air-out, air inlet end 111 is used for communicateing outdoor air, air supply end 112 is used for communicateing indoor air, purification module 120 is close to air inlet end 111, fan 130 is close to air supply end 112. The window sash assembly 200 includes a driver 210, a fixed shaft 220, and a plurality of blades 230 rotatably coupled to the fixed shaft 220. The vane 230 communicates indoor and outdoor, and the driver 210 serves to change the opening angle of the vane 230. The PLC controller 300 is used to control the rotation speed of the fan 130 and the operating state of the driver 210.
The section type indoor fresh air system in this season is divided into two working modes of an air conditioning season and a transition season. When the working state is in an air-conditioning season, the fan 130 supplies fresh air according to the indoor required fresh air volume, and the outdoor fresh air is filtered and purified by the purification module 110 and then is led into the room. Simultaneously, the sash window assembly 200 is opened in a linked manner. When the working state is in transition seasons, taking the transition from summer to autumn as an example, the indoor cold load is gradually reduced along with the reduction of the outdoor temperature, at the moment, if natural cold source ventilation is adopted, the heat exhaust quantity of the fresh air is increased along with the reduction of the outdoor temperature, and when the indoor cold load and the heat exhaust quantity of the fresh air reach balance, the indoor air conditioner can reach the required thermal environment by only exhausting heat by the fresh air without being started. Let the outdoor temperature at this time be twIf the indoor temperature is allowed to change within a certain range (such as 19-26 ℃), the outdoor equilibrium temperature when the indoor lower limit room temperature (such as 19 ℃) is defined as the lower switching temperature t for starting and stopping the air conditioner for supplying heatwhSimilarly, the outdoor temperature at the indoor upper limit room temperature (such as 26 ℃) is defined as the upper switching temperature t for starting and stopping the air conditioner for refrigerationwc. By definition, when the outdoor temperature is at twh～twcIn the meantime, the PLC controller 300 may be used to control the rotation speed of the fan 130 and the operating state of the driver 210, and a natural cooling source may be used to maintain the room temperature within an allowable range (19 to 26 ℃).
