The rotating speed of contracting machine.
Step 408, exits the control process of the rotating speed that compressor is adjusted according to actual motion electric current, and by compressor most
Big running current is updated to default maximum running current.
Specifically, during the rotating speed of compressor is adjusted according to actual motion electric current, need according to below equation, really
Determine the maximum (top) speed of compressor trouble free service at ambient temperature：
Predetermined protective current × the correction value of the compressor maximum (top) speed=compressor of trouble free service at ambient temperature, its
In, pre-stored several different temperature ranges are (for example：A areas, B areas, C areas, D areas, E areas etc.), different temperature range correspondences
Correction value arrange different, general environment temperature is higher, and correction value is less, it is ensured that can automatically controlled control components and parts temperature rise, it is special
It is not the temperature rise of power model, by the rotation speed regulating and controlling to compressor, in the case where automatically controlled reliability is allowed, it is ensured that the energy of convertible frequency air-conditioner
Enough maximum outputs.
Specifically, the control process of the rotating speed of compressor is adjusted according to actual motion electric current, as shown in figure 5, including：
Step 502, detects the actual motion electric current I of compressorrun。
Step 504, judges IrunWhether more than maximum running current Imax, if so, execution step 506；Otherwise, execution step
508。
Step 506, the rotating speed of compressor drop to predetermined threshold according to the first predetermined speed (such as 1rps/sec), and in real time
Detection IrunWhether more than maximum running current Imax, if so, execution step 510；Otherwise, execution step 512.
Step 508, compressor maintain rotating speed constant.
Step 510, when the rotating speed of compressor is down to predetermined threshold, IrunMore than Imax, shut down and show stopping protection code.
Step 512, the rotating speed of the first duration (such as 3 minutes) compressor afterwards is according to the second predetermined speed (such as 0.5rps/sec)
Compressor is risen under current environmental temperature during the maximum (top) speed of trouble free service, whether real-time detection Irun is less than or waits
In Imax, as Irun ＜ Imax, execution step 514；As Irun=Imax, execution step 516.Wherein it is preferred to, second
Predetermined speed is less than the first predetermined speed.
The rotating speed of compressor is promoted to maximum (top) speed by step 514.
Step 516, compressor run the second duration (such as 3 minutes) according to current rotating speed, and continuation judges Irun and Imax
Relation, until the rotating speed of compressor is promoted to maximum (top) speed.
In the above-described embodiments, with reference to the actual motion electric current of operation environment of air conditioner temperature and compressor, first determine whether
The unlocking condition of the step of ambient temperature and working condition adjust the rotating speed of compressor according to actual motion electric current as execution, and
Actual motion electric current and ambient temperature are detected in real time to adjust the rotating speed of compressor, avoid as far as possible limiting the maximum operation of compressor
Rotating speed, it is ensured that the optimization of household air-conditioner, only when working condition is in badness, just limits and adjusts compressor most
Big running speed, loses the partial properties of air-conditioning, to protect the automatically controlled device of air-conditioner and avoid air-conditioner to shut down as far as possible, carries
The high reliability of product, brings the air-conditioning service of more comfortableization to user.
Technical scheme is described in detail above in association with accompanying drawing, the present invention proposes a kind of control of new air-conditioner
Scheme processed, can regulate and control to the rotating speed of compressor, so as to avoid according to the actual motion electric current of ambient temperature and compressor
