Detailed Description
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1, the present invention provides a compressor control method, comprising: receiving an adjustment command for reducing an operating frequency of the compressor; acquiring the running frequency X of the compressor at the current moment and the running time t for continuous running according to the running frequency X; judging whether the operation time t is greater than or equal to the preset time t 0 The method comprises the steps of carrying out a first treatment on the surface of the When the operation time t is greater than or equal to the predetermined time t 0 Judging whether X-N is the shielding frequency of the compressor, wherein N=1 Hz or 2Hz; when X-N is not the shielding frequency of the compressor, the operating frequency of the compressor is controlled to operate according to X-N.
The compressor control method of the present invention comprises: receiving an adjustment command for reducing an operating frequency of the compressor; acquiring the running frequency X of the compressor at the current moment and the running time t for continuous running according to the running frequency X; judging whether the operation time t is greater than or equal to the preset time t 0 The method comprises the steps of carrying out a first treatment on the surface of the When the operation time t is greater than or equal to the predetermined time t 0 Judging whether X-N is the shielding frequency of the compressor, wherein N=1 Hz or 2Hz; when X-N is not the shielding frequency of the compressor, the operating frequency of the compressor is controlled to operate according to X-N. Therefore, under the condition of ensuring the operation reliability of the compressor, the right of controlling the operation frequency of the compressor is given to the user, the operation frequency of the compressor can be adjusted according to the tone quality experience of the user to the noise, the use participation feeling and the use comfort of the user to the air conditioner are increased, and the problem that the user of the air conditioner in the prior art cannot adjust the operation frequency of the compressor of the air conditioner according to the subjective tone quality experience of the user to the noise is solved.
In the compressor control method of the present invention, the masking frequency of the compressor means: in the frequency range of operation of a variable frequency compressor, some frequencies are not operated by the controller, also called masking points of the compressor.
When the variable frequency air conditioner adjusts the operation frequency of the compressor to X (unit: hz) according to indoor and outdoor environments, if a user feels that the noise of the air conditioner is too loud or the tone quality is not acceptable, a 'comfort adjustment' button on the remote controller can be pressed, and at this time, the remote controller sends an adjustment instruction for reducing the operation frequency of the compressor to the controller of the air conditioner so as to reduce the operation frequency of the compressor.
As shown in fig. 1, if the compressor is instructed to reduce the operating frequency by the adjustment while in the up-conversion state, the up-conversion process of the compressor is interrupted, and eventually the operating frequency of the compressor becomes lower, thereby resulting in a great reduction in the cooling and heating effects of the air conditioner. Accordingly, the compressor control method includes: when the operation time t is less than the predetermined time t 0 And when the compressor is in the ascending frequency state, ignoring the adjusting instruction and sending first reminding information to the user, wherein the first reminding information comprises the compressor in the ascending frequency state.
As shown in fig. 1, the compressor control method is applied to a compressor of an air conditioner, and includes: when the X-N is the shielding frequency of the compressor, judging whether the frequencies in the range from X-2N to X-10 are all the shielding frequencies of the compressor; when the frequencies in the range from X-2N to X-10 are all shielding frequencies of the compressor, judging whether the windshield gear A of the indoor fan of the air conditioner at the current moment is the highest gear of the indoor fan or not; when the windshield gear A of the indoor fan of the air conditioner at the current moment is not the highest gear of the indoor fan, controlling the running frequency of the compressor to run according to X-10-N, and controlling the windshield of the indoor fan to run according to the A+1 gear.
For example, when the windshield gear a of the indoor fan of the air conditioner is a high windshield gear at the current moment, the windshield of the indoor fan is controlled to operate according to the super-strong windshield gear so as to ensure the refrigerating or heating effect of the air conditioner.
When the frequencies in the range of X-2N to X-10 are not all the screening frequencies of the compressor, as shown in fig. 1, the operation frequency of the compressor is controlled to operate at the maximum frequency among the non-screening frequencies in the range of X-2N to X-10.
As shown in fig. 1, when determining whether a damper gear a of an indoor fan of an air conditioner is a highest gear of the indoor fan at a current time, the compressor control method includes: when the windshield gear A of the indoor fan of the air conditioner at the current moment is the highest gear of the indoor fan, the operation frequency of the compressor is controlled to operate according to X-10-N.

When the operation frequency of the compressor is continuously reduced by more than 10Hz, the comfort experience of a user is affected, if X-N is the shielding frequency of the compressor and the frequencies in the range from X-2N to X-10 are all the shielding frequencies of the compressor, the user is reminded of ' the continuous shielding frequency exists when the air conditioner is developed and designed ', if the user continues to execute comfort adjustment, the refrigeration or heating effect of the air conditioner is possibly reduced, and whether the operation frequency of the compressor of the air conditioner is continuously reduced or not ' is possibly caused; when the user selects to continuously reduce the operation frequency of the compressor of the air conditioner, considering the comfort experience of the user, whether the windshield gear A of the indoor fan of the air conditioner is the highest gear of the indoor fan at the current moment is needed to be judged, if the windshield gear A is provided with an upshift space, upshift treatment is carried out on the windshield of the indoor fan, so that the indoor fan operates according to the gear A+1, the heat exchange amount of the heat exchanger of the indoor unit is increased, and therefore the refrigerating and heating effects of the air conditioner are improved.
When the operating frequency of the compressor of the present invention is an odd number of frequencies, n=1 Hz, and in determining whether frequencies in the range of X-2N to X-10 are all the shielding frequencies of the compressor, the compressor control method includes: when the X-N is the shielding frequency of the compressor, judging whether the X-2N is the shielding frequency of the compressor or not; when the X-2N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-2N; when the X-2N is the shielding frequency of the compressor, judging whether the X-3N is the shielding frequency of the compressor; when the X-3N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-3N; when the X-3N is the shielding frequency of the compressor, judging whether the X-4N is the shielding frequency of the compressor or not; when the X-4N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-4N; when the X-4N is the shielding frequency of the compressor, judging whether the X-5N is the shielding frequency of the compressor or not; when the X-5N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-5N; when the X-5N is the shielding frequency of the compressor, judging whether the X-6N is the shielding frequency of the compressor or not; when the X-6N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-6N; when the X-6N is the shielding frequency of the compressor, judging whether the X-7N is the shielding frequency of the compressor; when the X-7N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-7N; when the X-7N is the shielding frequency of the compressor, judging whether the X-8N is the shielding frequency of the compressor or not; when the X-8N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-8N; when the X-8N is the shielding frequency of the compressor, judging whether the X-9N is the shielding frequency of the compressor; when the X-9N is not the shielding frequency of the compressor, controlling the operation frequency of the compressor to operate according to the X-9N; when the X-9N is the shielding frequency of the compressor, judging whether the X-10N is the shielding frequency of the compressor; when X-10N is not the shielding frequency of the compressor, the operation frequency of the compressor is controlled to operate according to X-10N.
