Start control method of air conditioner

Abstract

The invention relates to the field of air conditioners, and provides a start control method of an air conditioner. The air conditioner comprises a compressor, an evaporator, a condenser, an evaporation fan and a condensation fan. The method comprises the steps that when the air conditioner is started, the evaporation fan operates at a first preset rotating speed; and in the process from starting of the air conditioner to normal temperature adjusting operation, the frequency increasing process of the compressor has at most one stop point, and the current operation rotating speed of the evaporation fan is determined jointly according to the first preset rotating speed, the operation mode of the air conditioner, the outdoor environment temperature and the current operation frequency of the compressor, specifically, the current operation rotating speed of the evaporation fan is greater than the first preset rotating speed. The frequency increasing period of the compressor can be shortened, the air conditioner can quickly reach the normal temperature adjusting state, and the user experience can be improved; and in addition, it can be guaranteed that parts in the compressor cannot be excessively abraded in the continuous frequency increasing process of the compressor, and it can be guaranteed that the compressor normally operates for a long time.

Description

technical field

[0001] The invention relates to the field of air conditioners, in particular to an air conditioner startup control method. Background technique

[0002] When the air conditioner is started, because the refrigerant is in a low temperature state, a large amount of lubricating oil in the compressor is dissolved in the refrigerant, so at this time the compressor exhaust will carry a large proportion of lubricating oil.

[0003] In order to avoid insufficient lubrication of the compressor, in the prior art, multiple stop points are set during the compressor frequency up process. After the compressor is up frequency to the frequency of the stop point, it needs to keep running at this frequency within the set time to wait for it to be exhausted. The carried lubricating oil returns to the compressor again, and then continues to increase the frequency, that is, the process of increasing frequency is interrupted by multiple stop points, resulting in a long time for the...
