AI Technical Summary
Technical Problem
Existing air conditioners struggle to detect refrigerant leakage accurately when it occurs far from the main body, such as in the piping connecting the indoor and outdoor units, due to voltage drop from extended wiring, preventing the sensor from operating properly.
Method used
An air conditioner system with a sensor board that converts alternating current to direct current and adjusts voltage to ensure a predetermined voltage supply to refrigerant leakage sensors, using conversion and adjustment means to maintain sensor operation regardless of distance.
Benefits of technology
Ensures reliable detection of refrigerant leakage by maintaining sensor functionality even at distant locations, enhancing safety by enabling prompt detection and notification of leaks.

Abstract
[Problem] To provide an air conditioning device that uses a prescribed voltage to operate a sensor for detecting a refrigerant. [Solution] Provided is an air conditioning device 10 comprising a sensor 25 for detecting refrigerant leakage, the air conditioning device 10 including: a voltage conversion unit 310 that converts voltage from alternating current to direct current and outputs the voltage to a line; and a voltage adjustment unit 330 that adjusts the voltage inputted via the line. The voltage adjustment unit 330 supplies a prescribed voltage to the sensor 25.
