Air Conditioning and Coolant

A low side refrigeration system primarily consists of several key components: the evaporator, where the refrigerant absorbs heat from the environment and evaporates; the compressor, which circulates the refrigerant and increases its pressure; and the condenser, where the refrigerant releases heat and condenses back into a liquid. Additional components may include an expansion device to control refrigerant flow and pressure, and various sensors and controls to regulate the system's operation. Together, these parts work to maintain desired temperatures in refrigeration applications.

To set up a compressor limiter, first determine the threshold level where you want the compression to begin. Adjust the ratio to control how much the signal is reduced once it exceeds the threshold, typically setting it high (e.g., 8:1 or more) for limiting. Set the attack time to control how quickly the compressor responds to peaks and the release time for how quickly it returns to normal after the signal drops. Finally, adjust the output gain to ensure the overall volume level is consistent after compression.
