Evaluate the following statements about the fitted pressure switches and pressure sensors in an air conditioning system:

1. They are located in the high-pressure section of the air conditioning system.
2. These devices switch off the compressor if the air conditioning system pressure becomes too high or too low.
3. These devices regulate the pressure in the air conditioning system by controlling the thermostatic expansion valve.



Answer :

Final answer:

Pressure switches and pressure sensors play a vital role in maintaining the pressure levels in an air conditioning system.


Explanation:

Pressure switches and pressure sensors in an air conditioning system are crucial components that help regulate the pressure and ensure system safety. These devices are primarily located in the high pressure section of the system to monitor and control pressure levels. Pressure switches work by activating and deactivating the compressor based on preset pressure thresholds, while pressure sensors provide feedback to the control system.
