I. Introduction.
Refrigerant is the core part of the refrigeration system and plays a vital role in the refrigeration effect of air conditioners, refrigerators and other equipment. Fluoridation is an important operation in the process of refrigerant use, and the correct fluoridation method can ensure the normal operation of the refrigeration system and prolong the service life of the equipment. This article will introduce the steps and precautions of fluoridation of 32 refrigerants in detail to help you better understand and use this technology.
2. Prepare tools and materials.
Before proceeding with 32 refrigerant fluoride, we need to prepare the following tools and materials:
Vacuum pump: used to extract air and moisture from the refrigeration system to ensure the purity of the fluoridation process.
Fluorinated tube: Connect the refrigeration system to the fluorine bottle to ensure that the freon can be smoothly integrated into the refrigeration system.
Fluorine bottle: Fluorine bottle with 32 refrigerants, pay attention to choose the refrigerant that matches the refrigeration system.
Protective gloves and glasses: Protect the safety of the operator, avoid contact with refrigerants and prevent freon leakage and eye damage.
3. Steps.
Check the refrigeration system: Before adding fluorine, you need to check whether all parts of the refrigeration system are intact, especially the core components such as compressors, condensers, and evaporators. If damage or leakage is found, it needs to be repaired in a timely manner.
Vacuuming: A vacuum pump is used to vacuum the refrigeration system to remove air and moisture from the system. The time of vacuum pumping needs to be determined according to the volume of the system and the power of the vacuum pump, and it is generally necessary to pump the vacuum degree of the system to -01MPa or less.
Connect the fluorinated tube: Connect one end of the fluorinated tube to the fluorine bottle and the other end to the low-pressure side of the refrigeration system (usually the evaporator outlet). Make sure the connection is tightly connected to prevent freon leakage.
Open the valve of the fluorine bottle: Gently open the valve of the fluorine bottle and let the freon slowly enter the refrigeration system. Pay attention to the size of the valve opening to avoid excessive addition of freon.
Observe pressure changes: During fluoridation, the pressure changes in the refrigeration system need to be closely observed. When the pressure reaches a normal value (generally 0.).45~0.5MPa), you need to close the fluorine bottle valve and stop adding fluoride. If you notice an abnormal increase or decrease in pressure, you need to stop fluoridation immediately and check the cause.
Check for leaks: After fluoridation is complete, the refrigeration system needs to be checked for leaks. Soapy water can be applied to joints and welds to observe for air bubbles. If a leak is found, it needs to be repaired in a timely manner.
Cleaning and organizing tools: Once the fluoridation operation is complete, the tools and materials used need to be cleaned and organized. In particular, components that come into contact with refrigerants, such as vacuum pumps and fluorinated tubes, need to be thoroughly cleaned to avoid residues affecting the system.
4. Precautions.
Choosing the right refrigerant: Before proceeding with 32 refrigerant fluoridation, you need to ensure that the refrigerant you choose is a good match for your refrigeration system. Different types of refrigerants have different chemical and physical properties, and mixing them can lead to system damage or reduced performance.
Maintain a ventilated environment: When performing fluoridation operations, it is necessary to keep the operating environment well ventilated. Avoid prolonged inhalation of freon vapor, which can cause harm to health.
Follow safe operating procedures: Fluoridation involves high-pressure gases and toxic substances, so relevant safety operating procedures need to be followed. Wear protective gloves and glasses during operation to avoid accidents.
Periodic inspection and maintenance: Fluorination operations are only one part of the maintenance of a refrigeration system, and regular and comprehensive inspections and maintenance work are required to ensure the proper functioning of the system. This includes cleaning the condenser and evaporator, checking the operating status of the compressor, etc.
