• Temperature Sensors: These sensors measure the temperature of the air, refrigerant, and other components within the AC system. They are critical for regulating the cooling process and preventing freezing. Common types include:
  • Evaporator Temperature Sensor: Monitors the temperature of the evaporator coil, preventing it from freezing up.
  • Ambient Air Temperature Sensor: Measures the outside air temperature to help the control unit adjust the AC system’s performance.
  • In-Cabin Temperature Sensor: Measures the temperature inside the vehicle or room, allowing the system to maintain the desired temperature setting.
• Pressure Sensors: These sensors monitor the pressure of the refrigerant within the AC system. Pressure is a critical factor in the cooling process, and these sensors help ensure the system operates within safe and efficient parameters. Common types include:
  • High-Pressure Sensor: Monitors the pressure of the refrigerant on the high-pressure side of the system, protecting the compressor from damage.
  • Low-Pressure Sensor: Monitors the pressure of the refrigerant on the low-pressure side of the system, ensuring proper cooling.
• Humidity Sensors: Some advanced AC systems may include humidity sensors, which measure the moisture content in the air. This data helps the system control the dehumidification process and maintain optimal comfort levels.
• Refrigerant Leak Sensors: These sensors detect leaks of refrigerant, which can cause the AC system to lose its cooling ability.
