Causes of excessive discharge pressure of Freon compressor

The reasons for the high discharge pressure of Freon compressor mainly include the following aspects

  1. Refrigeration system failure: During the operation of the fluorine refrigerator, the exhaust pressure may increase due to the failure of internal components of the refrigeration system, such as the condenser, expansion valve, compressor and other parts.

  2. Condenser blockage: When impurities or sediments appear in the condenser, it will affect the heat transfer of refrigerant, lead to poor refrigeration effect and eventually lead to an increase in exhaust pressure.

  3. Too much refrigerant dose: During the installation and debugging of the fluorine refrigerator, there may be too much refrigerant dose, which will lead to too high pressure of the fluorine refrigerator and then affect the operation effect.

  4. Insufficient cooling water flow or high temperature: insufficient cooling water flow or high temperature will lead to poor heat dissipation effect of the condenser, which in turn will lead to an increase in condensation pressure and exhaust pressure.

  5. Non-condensable gas in the system: The existence of non-condensable gas in the system will also lead to the increase of condensation pressure and exhaust pressure.

  6. Blockage of the filter screen of the return pipe: Blockage of the filter screen of the return pipe will lead to poor refrigerant circulation, which will further affect the exhaust pressure.

  7. Condenser fouling: The fouling on the surface of condenser will lead to poor heat exchange, which will lead to the increase of condensation pressure and exhaust pressure.

  8. Improper selection of refrigerant: Choosing unsuitable refrigerant will also lead to excessive exhaust pressure.

The method for solving the problem that the discharge pressure of the Freon compressor is too high includes:

  1. Cleaning the condenser: use water or condenser cleaning agent to thoroughly clean impurities and sediments inside the condenser to ensure the normal operation of the condenser.

  2. Replace the refrigerant: If the exhaust pressure is high due to too much refrigerant, you can choose to replace it with a more suitable refrigerant or reduce the amount of refrigerant used.

  3. Check and replace the faulty parts: carefully check the refrigeration system and replace the faulty parts to ensure the normal operation of the system.

  4. Increase the suction pressure: reduce the compression ratio by increasing the suction pressure, thus reducing the exhaust temperature and pressure.

  5. Clean the filter screen of the air return pipe: If the filter screen of the air return pipe is blocked, it is necessary to clean the filter screen to restore the circulation of refrigerant.

  6. Cleaning the condenser scale: regularly clean the condenser scale to ensure its heat exchange efficiency.
