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

[0027] 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.

[0028] Generally speaking, because the larger the cooling flow, the higher the cooling / heating efficiency, therefore, when the refrigerant system is running, in order to meet the cooling / heating demand, the previous refrigeration system often strives for fast cooling / heating. The refrigerant flow is saturated, so the compressor will be driven at a very high speed, resulting in higher noise generated by the refrigerant flow. The larger the refrigerant flow, the higher the relative flow noise. In some special occasions, such as sle...

Abstract

The invention discloses an air conditioner and a control method and device thereof. The air conditioner comprises a coolant system, a throttle device, an outdoor fan and a variable frequency compressor; the coolant system is connected with an indoor-outer 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 the flow of the coolant reaches first preset flow; 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 are 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 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 of other...
