Description
Technical field
The present invention relates to domestic air conditioner, a kind of air-conditioner soft start controller to the little domestic air conditioner of the impact of electrical network when starting that makes of more clearly saying so.
Background technology
Present family expenses fixed frequency air conditioner device all can not pass through standard GB-17625.The test of projects such as voltage pulsation in 2 and flicker.Tracing it to its cause, is because the starting current of the compressor of existing family expenses fixed frequency air conditioner device is excessive.If reduce starting current simply, then can can't make compressor start because of starting torque is too small again.Existing family expenses fixed frequency air conditioner device all can not pass through standard GB-17625.The test of projects such as voltage pulsation in 2 and flicker.That is to say that the starting current of present domestic air conditioner is still excessive.
Purpose of the present invention is to overcome above-mentioned shortcoming and defect, provides a kind of and makes the starting current of air-conditioner little, bigger starting torque is arranged again, can pass through standard GB-17625.The soft start controller of the domestic air conditioner of the test of projects such as voltage pulsation in 2 and flicker.
Summary of the invention
In order to achieve the above object, the present invention is made up of the electronic circuit on the compressor that is connected air-conditioner.Electronic circuit is by the running electric capacity between the outer end points B of the outer end points A of the main coil that is connected in parallel on compressor and auxiliary winding, and be connected in startup capacitor control circuit between A, the B, be connected the press relay normally open contact between civil power live wire and the A point, be connected in parallel on the controllable silicon at press relay normally open contact two ends, be connected one-chip computer and auxiliary circuit thereof that silicon controlled control is extremely gone up, be connected line voltage testing circuit and the press relay on the one-chip computer and start electric capacity control relay coil and form to the dc source of above-mentioned circuit supply.Starting capacitor control circuit is in series with the parallel circuit that starts electric capacity and bleeder resistor after starting the series connection of electric capacity control relay normally open contact and NTC element again.
Also connecting transistor drive circuit respectively between one-chip computer and press relay and the startup electric capacity control relay coil.Also connecting the photoelectrical coupler drive circuit between the one-chip computer and the silicon controlled control utmost point.The bleeder circuit that voltage detecting circuit is made up of resistance and Zener diode is formed.
The present invention is like this work: air-conditioner is inserted civil power and power on.When air conditioner room unit sent off-premises station with power supply, one-chip computer started the conducting of electric capacity control relay coil, its normally open contact closure by the transistor drive circuit order.So controllable silicon conducting.One-chip computer can be controlled the starting resistor that is added on the compressor by controllable silicon, so compressor is activated.Behind the compressor start, the press relay gets electric, its normally open contact closure, and controllable silicon disconnects.Start electric capacity control relay dead electricity subsequently, its normally open contact disconnects.Start-up course so far finishes, and running electric capacity and compressor enter normal operating condition.The NTC element is a kind of negative tempperature coefficient thermistor, and its resistance value descends with its temperature.When air-conditioner startup electric capacity puts into operation, by the NTC element, can suppress effectively to control the starting current of compressor by starting the surge current of electric capacity, to starting electric capacity protective effect is arranged simultaneously.The effect of bleeder resistor is an earial drainage.After cutting off startup electric capacity control relay and normally open contact thereof, starting to assemble on the electric capacity has a large amount of electric charges, can discharge accumulating in the electric charge that starts on electric capacity the two poles of the earth by bleeder resistor, for the soft start next time of air-conditioner is got ready.The effect of photoelectrical coupler is to drive.Voltage detecting circuit is used for the detection of line voltage, the input one-chip computer.
One-chip computer is made up of MC68HC908JK3CP type or TNP87P808N type.The result of use of these two kinds of single-chip microcomputers is better.Also can select the one-chip computer of other model for use.Piezo-resistance also in parallel respectively between civil power live wire and the A point and between the ground wire of civil power live wire and compressor.Piezo-resistance is an element to voltage-sensitive.When the voltage that is added to the piezo-resistance two ends hour, the electric current that flows through piezo-resistance is very little, and piezo-resistance shows as the high resistant characteristic.When the voltage that is added to the piezo-resistance two ends arrived certain value greatly, the electric current that flows through piezo-resistance increased rapidly, and piezo-resistance shows as the low-resistance characteristic.It is used for the overvoltage protection to compressor.
According to the operation characteristic of monophase machine and the startup operation characteristic of fixed frequency air conditioner device, reduce starting resistor and can reduce starting current.But when reducing starting current, as not changing other parameter, staring torque will have certain decline.And to guarantee enough staring torques, then need to increase the capacity that starts electric capacity.Concrete starting resistor with start electric capacity and should mate according to test because of the different of press and system start-up time.
Task of the present invention comes to this and finishes.
The present invention can reduce the starting current of air-conditioner, to the impact of electrical network, passes through standard GB-17625 smoothly when reducing the air-conditioner startup.The test of projects such as voltage pulsation in 2 and flicker.It can be widely used in air-conditioner particularly in the family expenses fixed frequency air conditioner device.
