Problems solved by technology

At present, the method of reducing noise by controlling the operation of the compressor at low frequency has been widely adopted. However, the noise generated during the operation of the compressor between low frequency and high frequency has not been solved. The frequency of the compressor is between low frequency and high frequency. The noise generated during the lifting process will still disturb the user, and the user experience is not good

Embodiment Construction

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029]Since the refrigerant system is in a state of equal pressure before the start-up process of the refrigerant system, the pressure is determined by factors such as the external temperature and the amount of refrigerant at that time. Taking refrigeration as an example, when the refrigerant system is started, the compressor will deliver gaseous refrigerant to the high-pressure side of the refrigerant system, which will increase the refrigerant pressure on the high-pressure side and reduce the refrigerant pressure on the low-pres...

Abstract

The invention discloses a control method of an air conditioner, a control device of the air conditioner and the air conditioner. The air conditioner comprises a coolant system, a throttle device and a variable frequency compressor; the coolant system is connected with an indoor-outdoor heat exchanger; the throttle device is connected with the indoor-outdoor heat exchanger; the variable frequency compressor drives coolant to circulate. The control method includes the steps of controlling the variable frequency compressor of the air conditioner to start with a first frequency when the air conditioner is in a silent mode; with a first preset time passing by, controlling the variable frequency compressor to increase in frequency at a first preset rate; judging whether or not current frequency of the variable frequency compressor reaches a value corresponding to a set noise value set in the silent mode; if yes, controlling the variable frequency compressor to stop increasing in frequency. The control method according to the embodiment has the advantages that flow of the coolant and impact thereof can be effectively reduced, leading to reduced coolant noise and mechanical noise, interference is avoided for users, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an air conditioner control method, an air conditioner control device and the air conditioner. Background technique [0002] In order to speed up the cooling and heating speed of the air conditioner, at present, most air conditioner manufacturers can realize rapid cooling or heating by controlling the frequency of the frequency conversion compressor to rise and fall rapidly. However, the rapid rise and fall of the compressor frequency will inevitably increase the noise of the compressor, and will also lead to rapid changes in the pressure of the refrigeration system, thereby increasing the noise generated by the refrigerant flow in the evaporator of the indoor unit. Sensitive people, such as the elderly and children, will cause discomfort, especially at night when people are resting. Excessive noise will seriously disturb the rest of users, and even disturb the rest ...
