OK.
The wiring of the defrost pipe is roughly divided into four types: series, parallel, star connection, delta connection, and the working voltage of low-voltage direct current heating is generally 12V, 24V, 36V, 48V, 72V, 110V. Common AC heating tube working voltage is generally 220V, 380V, and a small amount of 110V.
The defrost tube can also defrost itself when it is frosted, and its existence allows you to no longer worry about freezing inside the refrigerator.
