Start-up control method of air conditioner

Abstract

The invention relates to the field of air conditioners, and provides a start-up control method for an air conditioner, wherein the air conditioner includes a compressor, an evaporator, a condenser, an evaporating fan and a condensing fan; Speed ​​operation; during the process of the air conditioner from starting to normal temperature regulation operation, the compressor's frequency-up process has at most one stop point, and the current operating speed of the evaporative fan is based on the first preset speed, the operating mode of the air conditioner, the outdoor The ambient temperature and the current operating frequency of the compressor are jointly determined, and the current operating speed of the evaporative fan is greater than the first preset speed. The present invention is beneficial to reduce the frequency-up cycle of the compressor, to make the air conditioner reach a normal temperature regulation state quickly, and to improve user experience; and to ensure that the components in the compressor will not continue to increase the frequency during the compressor's frequency-up process. Excessive wear and tear in the middle is conducive to ensuring the normal operation of the compressor for a long time.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a startup control method of an air conditioner. Background technique [0002] When the air conditioner is started, since the refrigerant is in a low temperature state, a large amount of lubricating oil in the compressor is dissolved in the refrigerant, so the compressor exhaust will carry a large proportion of lubricating oil at this time. [0003] In order to avoid insufficient lubrication of the compressor, in the prior art, multiple stop points are set during the compressor frequency up-conversion process. After the compressor frequency is up-converted to the frequency at which the stop point is located, it needs to keep running at this frequency for a set period of time to wait for the exhaust to be exhausted. The lubricating oil carried is returned to the compressor again, and then continues to increase the frequency, that is, the frequency increase process is interrupted by ...

Problems solved by technology

[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 compressor to increase frequency, resulting in the air conditioner needing to run for a long time before it can It plays the role of normal temperature adjustment, which is not conducive to user experience
