What is the high pressure and low pressure pressure range of refrigerant in the cold dryer

The high and low pressure pressure ranges of the refrigerant of the cold dryer are important operating parameters, and its normal range is crucial to ensure the stable operation of the cold dryer. The following are the normal ranges for high and low pressure of refrigerant:

  1. Refrigerant high pressure range:
    • The normal high pressure range for refrigerant is usually between 1.2Mpa and 1.6Mpa. This range ensures that the cold dryer can efficiently perform heat exchange and maintain a stable operating state. When the refrigerant high pressure exceeds this range, high pressure protection may be triggered, causing the machine to snoop to protect the compressor and system from damage.
  2. Refrigerant low pressure range:
    • The normal range of refrigerant low pressure is usually between 0.4Mpa and 0.6Mpa (there are also data that the low pressure range is 0.2-0.55MPa). Maintaining a low pressure within this range helps ensure the compressor is operating effectively and avoids too low pressures that lead to system efficiency drops or failures. When the low pressure of the refrigerant is below a certain value, low pressure protection may be triggered to prevent the system from being damaged by too low pressure.

In short, in order to maintain the optimal performance and stable operation of the cold dryer, the high and low pressures of the refrigerant should be checked and adjusted regularly to ensure that they are within the normal range. If abnormal pressure is found, troubleshooting should be done in time to avoid unnecessary damage to the equipment.
