Anti-frosting method and system for air conditioner

Abstract

The invention provides an anti-frosting method and system for an air conditioner. The method includes the steps that meteorological parameters of the area where the air conditioner is located are obtained, wherein the meteorological parameters comprise temperature information and humidity information of the area where the air conditioner is located; according to the temperature information and the humidity information of the meteorological parameters, the dew point temperature of the area where the air conditioner is located is obtained; and according to the dew point temperature, operation parameters of the air conditioner are adjusted, so that the low-pressure temperature corresponding to operation low pressure of the air conditioner is higher than or equal to the dew point temperature. The air conditioner is well combined with the meteorological parameters of the area where the air conditioner is located, the dew point temperature of the area where the air conditioner is located is worked out through the meteorological parameters, operation of the air conditioner is adjusted according to the dew point temperature, the low-pressure temperature corresponding to the operation low pressure of the air conditioner is always higher than or equal to the dew point temperature of the area where the air conditioner is located, and therefore the air conditioner is free of a defrosting phenomenon even in the environment where the temperature is low and humidity is increased, the heat exchange effect of the air conditioner cannot become bad since the air conditioner does not frost, and the heating effect of the air conditioner is effectively improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner anti-frost method and system. Background technique [0002] The control of traditional air conditioners is generally limited to the real-time temperature of the unit at the installation site. It is impossible to know the air humidity and monsoon conditions, and there is no predictability for local climate changes. All controls are based on relatively fixed modes and parameters. As a result, the air conditioner cannot be well integrated with the local climate conditions. When the temperature is low and the humidity increases, the air conditioner is prone to frost, resulting in poor heating effect of the air conditioner. Contents of the invention [0003] In view of this, it is necessary to address the problem that the traditional air conditioner is prone to frost when the temperature is low and the humidity increases, resulting in poor heating effect ...
