A refrigerant filling machine is a device specifically used to add or replace refrigerant in air conditioning and refrigeration equipment. Below I will explain the application and maintenance points of refrigerant filling machine in detail.

Application of refrigerant filling machine：

1. Refrigerant filling: The main function of a refrigerant filling machine is to add refrigerant to air conditioning or refrigeration equipment. It compresses the refrigerant and then delivers it to the equipment through pipes.

2. Replacement of refrigerant: in the case of need to replace the refrigerant, the refrigerant filling machine can accurately control the filling amount to ensure that the refrigerant dosage in the equipment meets the requirements.

3. Applicable to a variety of refrigerants: modern refrigerant filling machine can be used for a variety of refrigerants, including high pressure, medium pressure, low pressure and other ordinary refrigerants, as well as flammable and slightly combustible refrigerants.

4. Leak detection and vacuum: The refrigerant filling machine usually has the function of leak detection and vacuum, which can detect whether there is a leak in the air conditioning pipeline and draw vacuum for the equipment pipeline.

5. Add refrigeration oil: some refrigerant filling machines also have the function of adding refrigeration oil to the air conditioning system.

   
   

   
   

   
   

Maintenance of refrigerant filling machine：

1. Daily cleaning: Keeping the refrigerant filling machine clean is a basic requirement of maintenance. Especially near the fan, it needs to be dusted every day to prevent the accumulation of dust affecting heat dissipation.

2. Check vacuum pump oil: If the equipment uses vacuum pump oil, check the cleanliness of the oil regularly. Replace the oil in time if it is cloudy.

3. Program calibration: According to the service life and wear of the flow sensor, it may be necessary to calibrate the refrigerant filling machine every 3 years or so to ensure the accuracy of filling.

4. Check the leak alarm: for the flammable refrigerant filling machine, it is necessary to check whether the leak alarm works normally regularly to ensure that the alarm can be issued in time when a leak occurs.

5. Check the ventilation system: check whether the refrigerant filling machine's ventilation system is unblocked, and ensure that the refrigerant can be discharged to the outdoor ventilation area in time in case of leakage.

6. Read the instruction manual: read the equipment instruction manual carefully to understand the specific maintenance content and operation steps. If in doubt, contact the manufacturer for support.

7. Regular maintenance: carry out regular maintenance according to the equipment instruction manual, including replacing parts, checking electrical connections, etc.

Through the above application and maintenance methods, the normal operation of the refrigerant filling machine can be ensured and its service life can be extended. At the same time, it also helps to ensure the refrigeration effect and operation stability of the air conditioning or refrigeration equipment.
