Air conditioner soft start-up control device

Abstract

This invention discloses a sort of soft startup control set which can settle the voltage rebound and radiance of the air condition, it relates to the area of the air condition technique and settle the bug that the electricity is too big when air condition startup in existing technique. This set consists ofthe electron circuitry connected in the compressor of the air condition: the main winding after the silicon control connects with the normal open port of the relay with a reamer and two flings in parallel they connect with the compressor in series, the startup capacitance, the discharge resistance connected with the startup in parallel, the negative temperature coefficient ceramics heat-variable element connected with the startup capacitance, the normal close port of the relay with a reamer and two flings, and after it connects with the running capacitance in parallel they connect with the subsidiary winding of the compressor. Hereinbefore they connect between the zero line and the front line by the common port of the compressor after connected with them in parallel. The control pole of the silicon control connects with the main control chip and peripheral circuit which consists ofthe DC power circuit, the voltage check circuit, the zero cross detection circuit and the control relay with a reamer and two flings loop circuit. It can debase effectively the startup electricity of the air condition and augment the startup torsion when the compressor operates at low voltage in this invention.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a soft start control device for solving air conditioner voltage fluctuations and flickers. Background technique [0002] During the starting process of the air conditioner, its starting current is 6 to 8 times the rated current. Such a large current will inevitably cause a great impact on the power grid and power supply equipment. At the same time, due to the large starting current and the large voltage drop of the line, the compressor cannot start when the power supply voltage is low, and cannot cool or heat, resulting in the air conditioner not being able to work normally. At present, domestic air conditioners with fixed frequency cannot pass the tests of voltage fluctuation and flicker in the national standard GB-17625.2. Some countries and regions also set strict technical barriers to the starting current, so the excessive starting current also affects the export tr...
