AI Technical Summary
Technical Problem
In existing air conditioners, aging and poor contact in the connecting wires can lead to increased resistance, causing overheating and even fires, posing safety hazards and affecting the lifespan of the air conditioner.
Method used
An AC voltage and current detection module is added to the control circuit of the indoor and outdoor units of the air conditioner. By calculating the AC voltage difference and operating current, the operating status of the compressor can be accurately controlled, reducing the power loss of the connection line.
Benefits of technology
It effectively reduces power loss in the connection line, improves the safety and reliability of the air conditioner, extends the service life of the air conditioner, and avoids fire risks.

Abstract
The application provides an air conditioner and a control method thereof. The air conditioner comprises an indoor unit and an outdoor unit connected through a connecting line. The outdoor unit comprises an outdoor controller configured to receive a first alternating voltage on the indoor side, a second alternating voltage on the outdoor side, and an operating current on the outdoor side; determine a loss power of the connecting line according to the first alternating voltage, the second alternating voltage, and the operating current; generate an operating state control instruction based on the loss power, and send the operating state control instruction to the outdoor controller so that the outdoor controller controls an operating state of a compressor of the outdoor unit in response to the state control instruction. Thus, the problem that the resistance of the connecting line increases due to aging and poor contact, the air conditioner line overheats, the air conditioner is damaged, and even a fire is caused is solved, and the safety and reliability of the air conditioner are improved. Meanwhile, the air conditioner can still operate at a certain power after the impedance of the connecting line increases, and the operating life of the air conditioner is prolonged.
