Description

A kind of bimodulus of DC frequency converting air-conditioner compressor starts control method and system
Technical field
The invention belongs to air-conditioning variable-frequency motor control technology field, the bimodulus that relates in particular to a kind of DC frequency converting air-conditioner compressor starts control method and system.
Background technology
In summer or the cold winter of sweltering heat, for the air-conditioning product, its speed that temperature descends or rises between the start back room that powers on can directly have influence on user's impression, and therefore start refrigeration or the speed of heating are one of indexs of weighing the air-conditioning product comfort.
For DC frequency converting air-conditioner, under equal conditions, the frequency of compressor operating is more high, and its refrigerating capacity or heating capacity are also more high, and the speed that indoor temperature descends or rises is also more fast.
Because the restriction of compressor lubrication technology and startup control technology, existing DC frequency converting air-conditioner all is to start with low frequency, rises to the high frequency operation with slower acceleration then.In the ordinary course of things, from compressor start to the compressor raising speed to 50Hz(1Hz=60 revolutions per second) more than need about 1 minute time, this startup control method is referred to as " common slow start pattern " usually, cause the speed of air-conditioning start refrigerating/heating slow thus, influenced the comfortableness of air-conditioning product for the user.
Fig. 1 is structure and the work schematic diagram of DC frequency converting air-conditioner control system, and the DC frequency converting air-conditioner control system mainly is made up of remote controller, indoor control and outdoor controller three parts.The course of work is: the user sends power-on command to indoor controller by remote controller, indoor controller is transmitted to power-on command outdoor controller and opens inner blower, outdoor controller is opened outer blower fan and compressor after receiving power-on command, and sends the operation information of off-premises station to indoor controller.For the common slow start pattern that most DC frequency converting air-conditioner compressors adopt, its control procedure is divided into following four-stage:
The 1st stage: rotor location; In about 2 seconds consuming time of this stage, purpose is the locus at clear and definite its place before the rotor in the control compressor rotates, and some control scheme also can be skipped this stage, directly enters for the 2nd stage.
The 2nd stage: speed open loop, current closed-loop low speed drag; Consuming time being generally 3～5 seconds of this stage, the dragging speed of rotor is lower, and generally about 1Hz～5Hz, the rotor process of dragging can be that constant rotating speed drags to dragging speed, also can be to drag with realization from the speed that 0Hz accelerates gradually.
The 3rd stage: speed closed loop; This stage is consuming time shorter, mainly is after speed ring adds control loop, and control loop can be through the process of a vibrational stabilization (be generally that 5Hz～10Hz), whole process approximately continues 1～2 second time so that rotor reaches target velocity.
The 4th stage: raising speed is to target velocity; Owing to reasons such as compressor drum is lubricated, system pressure balance, noises, this stage is consuming time the longest, and rotor rises to more than the 50Hz from 1Hz with 1Hz/s or slower acceleration.
Therefore, the common slow start pattern of DC frequency-changeable compressor is from starting raising speed to needing about about 50 seconds time more than the 50Hz, and is consuming time longer, thereby the refrigerating/heating speed that causes starting shooting is slow.
At the above-mentioned existing problem of common slow start pattern, prior art provides a kind of quick startup control method of DC frequency-changeable compressor, it can realize that compressor from starting raising speed to the time that only needed for 3～6 seconds more than the 50Hz, makes start refrigerating/heating speed that significant lifting arranged.Generally will adopt high-frequency controling signal in 10 seconds, to make the running frequency of compressor reach about 50Hz fast in the industry or higher control method is referred to as the quick start-up mode of high frequency.
For the quick start-up mode of the high frequency of compressor, its control procedure generally comprises following three phases (having omitted the rotor positioning stage):
The 1st stage: speed open loop, current closed-loop drag; Power frequency is [10Hz, 20Hz], and amplitude is I 1Be the rated working current value of the motor of compressor of air conditioner, I 2Minimum demagnetization current for the motor of compressor of air conditioner.
The 2nd stage: speed closed loop; Target velocity during speed closed loop is [3000r/min, 6000r/min].
The 3rd stage: raising speed is to target velocity; The target velocity in this stage is not less than the closed-loop speed in the 2nd stage, and the raising frequency acceleration is [0.5Hz/s, 2Hz/s].
Above-mentioned Hz is rotor rotary speed unit, 1Hz=60 revolutions per second; Hz/s is the unit of rotary acceleration or deceleration, and 1Hz/s is to be increased 1Hz each second or reduce 1Hz.
Can promote air-conditioning start refrigerating/heating speed though above-mentioned high frequency starts control model fast, also there is certain defective in it, is exactly to start fast under the unbalanced condition of system pressure, causes the compressor start failure easily and demagnetizes.
In sum, prior art is carried out the quick startup of high frequency and is caused compressor start failure easily and the problem of demagnetization when the air-conditioning system pressure imbalance.
Summary of the invention
The object of the present invention is to provide a kind of bimodulus of DC frequency converting air-conditioner compressor to start control method, be intended to solve prior art and when the air-conditioning system pressure imbalance, carry out high frequency and start the compressor start failure that causes fast and the problem of demagnetization.
