Control method and control system of air conditioner under high-humidity heating working condition

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method and a control system of the air conditioner under a high-humidity heating working condition, aimingat solving the problem that the rapid heating effect is poor due to long frequency rising time in an existing air conditioner starting and frequency rising control method. To achieve the purpose, thecontrol method comprises the steps that the ambient humidity is acquired; when the ambient humidity is greater than the set humidity, the opening of the expansion valve is adjusted to a first target opening; a compressor of the air conditioner is started in the process of adjusting the opening of the expansion valve to the first target opening; and the compressor is subjected to staged continuousfrequency rising according to multiple set velocities. By allowing the compressor to be subjected to the staged continuous frequency rising at different frequency rising velocities after being started, normal oil return of the compressor can be ensured, the frequency rising time of the compressor can be shortened substantially, the purpose of rapid heating is further achieved, the comfortablenessof the air conditioner is improved, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning control method and system under high-humidity heating conditions. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and this requirement is particularly evident in household appliances. Taking an air conditioner as an example, in order to meet the needs of users for rapid heating and thus bring a more comfortable experience, the existing air conditioner generally makes the compressor quickly increase to a higher frequency when it is first turned on. When the compressor is running, the refrigerant in the compressor will be quickly discharged and circulated in the piping system. During the circulation process, the lubricating oil will be discharged from the compressor together with the refrigerant and enter the pipeline. Only when the discharged lubricating oil re...
