In the refrigeration system, excessively high high pressure and excessively low low pressure are common hidden dangers affecting the stable operation of equipment. They are directly related to refrigeration efficiency and equipment service life, and are also key issues that need to be focused on in operation and maintenance.

         Excessively high high pressure is likely to cause overload of the compressor, intensify component wear, and may also lead to excessive pipeline pressure, refrigerant leakage, and even damage core components. Excessively low low pressure will result in insufficient refrigeration capacity, reduced heat exchange efficiency, increased energy consumption, and affect the stability of the system cycle.

         Such abnormalities are mostly caused by system blockage, abnormal refrigerant or component failures. It is necessary to timely investigate hidden dangers, calibrate pressure parameters, standardize operation procedures, ensure that high and low pressures are within a reasonable range, and ensure the efficient, safe and stable operation of the refrigeration system while reducing operation and maintenance costs.
