Abstract

The invention discloses an anti-freezing method for a fresh air duct of an air conditioner. The air conditioner is provided with the fresh air duct, a fresh air fan, a heating device, and a fresh airinlet pipe connected to the air inlet of the fresh air duct, wherein the fresh air fan is arranged in the fresh air duct; the heating device is arranged in the fresh air inlet pipe, or the heating device is arranged at the air inlet of the fresh air duct; and the anti-freezing method for the fresh air duct of the air conditioner comprises the following steps of obtaining air temperature and indoordew point temperature on the fresh air duct after turning on the fresh air fan; and controlling the heating device to heat when the difference between the indoor dew point temperature and the air temperature is greater than or equal to a first preset threshold. The invention also discloses an air conditioner and a storage medium. The invention can effectively prevent the temperature of the freshair entering the room outside from being too low to cause the indoor air to freeze when coming into contact with a purification device in the fresh air duct, and prevent the purification device from freezing and affecting the purification effect.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner and its fresh air duct anti-freezing method and storage medium. Background technique [0002] Air conditioners commonly used today include air conditioners, purifiers, etc. In the process of air conditioners and purifiers adjusting the indoor environment, the general cycle is used to adjust the indoor environment, and the indoor environment is circulated for a long time, which is easy to cause too much carbon dioxide in the room. Some air conditioners have added a fresh air inlet pipe and a fresh air duct, and the fresh air inlet of the fresh air inlet pipe extends to the outside, and the fresh air enters through the fresh air outlet, and introduces fresh air indoors from the fresh air duct to increase the freshness of the indoor air. However, when the outdoor ambient temperature where the air conditioner is located is too low, when the too low fresh a...
