Third, the circuit composition of air conditioning controller
1, temperature detection
There are mainly room temperature (room temperature), inner coil temperature (tube temperature) and outer coil temperature.
Temperature measurement is to change the resistance of thermistor after temperature change, and use its voltage division ratio with fixed reference resistor to convert temperature change into voltage change, and then turn it into digital signal through A/D conversion.
The temperature measuring range of air-conditioning controller is small, generally from sixty or seventy degrees above zero to ten degrees below zero, so the thermistors used are mostly small resistance types such as 5K3470, 10K3950.
2. Humidity detection
Humidity is detected by a humidity sensor.
3. Infrared remote control reception
The infrared remote control signal emitted by the remote controller is received by the infrared receiver.
4? Three-minute delay protection circuit
The compressor can't be started immediately after stopping, and it needs to be separated by three minutes, otherwise the compressor will have a liquid hammer phenomenon, which will cause parts damage and affect the service life of the compressor. However, the accuracy of delay is not high, and it can be detected whether the power outage time exceeds 3 minutes by resistance-capacitance timing.
5? Auxiliary circuits, such as display output and key input circuits.
