New fan and anti-cold air control method and apparatus therefor

A non-transitory computer readable storage medium having stored thereon computer programs that, when executed by a processor, cause the anti-cold-air control method for a fresh air machine, which comprises:

• during a process of switching the fresh air machine from a heating mode to a refrigeration mode, obtaining, in real time, a set temperature and a delivery air temperature of the fresh air machine, and an external temperature of an indoor heat exchanger of the fresh air machine;
• obtaining a current outlet wind speed and a set wind speed of the fresh air machine;
• and
• adjusting an outlet wind speed of the fresh air machine based on the set temperature, the delivery air temperature, the external temperature of the indoor heat exchanger, the current outlet wind speed and the set wind speed.

An anti-cold-air control device for a fresh air machine, comprising:

• a temperature obtaining module, configured to, during a process of switching the fresh air machine from a heating mode to a refrigeration mode, obtain, in real time, a set temperature and a delivery air temperature of the fresh air machine, and an external temperature of an indoor heat exchanger of the fresh air machine;
• a wind speed obtaining module, configured to obtain a current outlet wind speed and a set wind speed of the fresh air machine;
• and
• a wind speed adjusting module, configured to adjust an outlet wind speed of the fresh air machine based on the set temperature, the delivery air temperature, the external temperature of the indoor heat exchanger, the current outlet wind speed and the set wind speed.
