Problems solved by technology

When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and affects the user experience

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a frosting inhibition control method for an air conditioner. In order to effectively suppress the frostingspeed of the air conditioner, the frosting inhibition control method for the air conditioner comprises the following steps that the current value of an outdoor fan of the air conditioner is detected;and the rotating speed of the outdoor fan is controlled according to the current value of the outdoor fan. According to the method, the rotating speed of the outdoor fan is controlled mainly by utilizing the current value of the outdoor fan, and the frosting speed of the air conditioner is delayed as much as possible on the premise of ensuring the heating operation efficiency of the air conditioner, so that the defrosting frequency is reduced, and the influence on the indoor temperature is reduced. Particularly, by comparing the real-time current value of the outdoor fan with a standard current value, the growth trend of the current of the outdoor fan is judged, and the possibility of frosting of the outdoor unit and the frosting speed can be more accurately judged according to the growthtrend of the current of the outdoor fan, so that the rotating speed of the outdoor fan is adaptively adjusted, and the frosting speed of the air conditioner is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a control method for suppressing frost formation of an air conditioner. Background technique [0002] As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased by the refrigerant passing through the circulation pipeline through high-pressure / low-pressure / gas / liquid state transitions, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the in...
