What should be monitored to prevent compressor overheating?

To effectively prevent compressor overheating, it is essential to monitor various critical factors that can influence its operational temperature. This includes ambient temperature, discharge pressure, and oil level.

Monitoring ambient temperature is crucial because high surrounding temperatures can elevate the temperature of the compressor, leading to overheating. Keeping an eye on the ambient conditions ensures that the compressor operates within its safe temperature range, particularly in environments that vary significantly in temperature.

Discharge pressure is another key factor; if the pressure at the compressor's discharge exceeds safe limits, it may indicate that the compressor is working harder than normal, generating excess heat. Monitoring discharge pressure helps to identify potential overload conditions that could lead to overheating.

Finally, maintaining an adequate oil level is vital as oil not only lubricates the compressor components but also helps in dissipating heat. Insufficient oil can lead to increased friction and, consequently, higher temperatures, which may cause overheating.

By integrating monitoring of all these elements, you can create a comprehensive approach to prevent compressor overheating, making it clear why the correct answer encompasses all the mentioned factors.
