≤ a, wherein a are positive constant.
Step S308, if step S306 judged result is yes, controls the compressor 100 of air-conditioning to shut down, open air-conditioning
Air refreshing device 200, indoor environment is introduced by outdoor air.After air-conditioning enters inletting fresh air pattern, compressor 100 stops first
Machine, terminate refrigeration or heating.Outdoor unit heat exchanger no longer needs to exchange heat, therefore outdoor machine fan can stop operating.
Step S310, the rotating speed of indoor machine fan 530 of air-conditioning is adjusted, its caused wind speed is higher than default wind speed, to carry
The import volume of high outdoor air so that indoor environment temperature reaches target temperature as early as possible.
Step S312, the wind deflector 510 of indoor set is controlled to turn to the maximum position of air output, to improve going out for indoor set
Wind air quantity.
Step S314, the inletting fresh air icon of the display screen 520 of indoor set is lighted, to prompt user's inletting fresh air pattern to open.
Step S316, judges whether air-conditioning meets the termination condition of inletting fresh air pattern.The termination condition bag of inletting fresh air pattern
Include：In the case of air conditioner refrigerating, Tr≤Ts；In the case of air-conditioning heating, Tr >=Ts.
Step S318, if step S316 judged result is yes, air refreshing device 200 is closed, to stop outdoor air
Import indoor environment.After indoor environment temperature has reached the target temperature of user's setting, terminate the inletting fresh air pattern of air-conditioning,
To cause indoor environment temperature to tend towards stability.
Step S320, the rotating speed of indoor machine fan 530 is adjusted, its caused wind speed is less than default wind speed, to save electric energy.
Step S322, extinguish the inletting fresh air icon of display screen 520, to prompt user that inletting fresh air pattern terminates.
After inletting fresh air pattern terminates, indoor environment temperature can slowly change, as indoor environment temperature Tr and indoor objects temperature
When degree Ts difference reaches a again, it may be considered that reopen inletting fresh air pattern.
