The temperature sensor uses two thermal resistors, Pt100 and Cu50. The evaporation temperature and ambient temperature of the three banks use Pt100 thermal resistance sensor, and the other uses low-cost Cu50 thermal resistance sensor. The suction and discharge pressure of the compressor is detected by the YSG-02 pressure transmitter. The transmitter can be displayed locally and converts the pressure signal into a 0 to 10 mA DC signal to the I/V Conditioning Board.
The operation of the frequency converter brings a lot of interference to the system, which not only generates radio interference, but also generates serious high-order harmonic interference power supply, which causes the computer control system to collapse and cannot truly reflect the actual value of the measuring point, so that the control system Mistakes and oscillations occur. We use an isolation amplifier to separate the interference from the output channel, and use the RC filter and software low-pass filter to remove the unreasonable pulse value to eliminate the interference generated by the inverter.
The air conditioner has a temperature sensing device that receives information on temperature changes. Originally, it has a "thermistor" installed, and the resistance value changes with temperature. When the temperature rises, the resistance value decreases, and vice versa. It is precisely because of the change in the resistance value that the potential changes in the circuit, these changes are collected and processed by the microprocessor, and become a command to control the compressor or other components to start or stop working. When the compressor is started, the air in the room and the air in the air conditioner are constantly exchanged, causing the indoor temperature to continuously decrease. When the room temperature is lower than the predetermined temperature, the air conditioner makes a judgment by the microprocessor to automatically stop the operation of the compressor, so that the cooling is terminated.
