Firstly, we need to understand where the air in the refrigeration system comes from? The reason is that the pipes are already filled with air when we connect them. Therefore, it is necessary to use equipment to expel the air from the system. If it is not fully removed, air will remain in the refrigeration system of the chilled water machine. If it's difficult to determine the amount of air in the refrigeration system, the following phenomena can be used to judge:
Condensation pressure is too high.
2. Excessive exhaust gas temperature
3. The pressure gauge exhibited significant fluctuation.
The presence of these three phenomena indicates a significant amount of air in the refrigeration system. It is crucial to address this promptly, as failure to do so can lead to ice blockages. Ice blockages not only reduce refrigeration efficiency but can also cause system shutdowns. Continuous pressure drops can also damage the compressor.
