INTEGRATED

INTEGRATED VENDING MACHINE REFRIGERATION UNIT is an integrated refrigeration unit, the heat transfer medium is oil. It has good thermal stability, accurate temperature control and a large temperature control range, the compressor is a key component of a unit compressor, and the quality of the compressor is directly related to INTEGRATED The stability of the VENDING MACHINE REFRIGERATION UNIT unit. So be careful in maintenance. The following are the maintenance steps of INTEGRATED VENDING MACHINE REFRIGERATION UNIT, I hope it will be helpful to your work.

INTEGRATED VENDING MACHINE REFRIGERATION UNIT

1. Change the lubricating oil
   After long-term use of INTEGRATED VENDING MACHINE REFRIGERATION UNIT, the oil quality of lubricating oil decreases, and the impurities and moisture in the oil increase. Therefore, the oil quality should be regularly observed and checked. Once a problem is found, it should be replaced in time, and the brand of lubricant to be replaced must comply with the technical data.

2. Replace the filter dryer
  The filter dryer is an important part to ensure the normal circulation of INTEGRATED VENDING MACHINE REFRIGERATION UNIT. Since water and refrigerant are incompatible with each other, if the system contains water, it will affect the operating efficiency of INTEGRATED VENDING MACHINE REFRIGERATION UNIT. Therefore, it is very important to keep the system dry. The filter element in the dryer must be replaced regularly.

3. Safety valve
   Check that the condenser on the INTEGRATED VENDING MACHINE REFRIGERATION UNIT is a pressure vessel. According to regulations, a safety valve should be installed on the high-pressure side of the INTEGRATED VENDING MACHINE REFRIGERATION UNIT, that is, the main body of the condenser. Once the INTEGRATED VENDING MACHINE REFRIGERATION UNIT is in an abnormal working environment, the safety valve can automatically release the pressure to prevent possible damage to the human body caused by high pressure. Therefore, regular inspection of the safety valve is essential to the safety of the entire INTEGRATED VENDING MACHINE REFRIGERATION UNIT.

4. Clean the condenser
  Because the cooling water of the water-cooled condenser is open-loop type, the commonly used tap water is circulated through the cooling tower. When the content of calcium salt and magnesium salt in the water is large, they are easily decomposed and deposited on the cooling water pipe to form scale, thereby affecting heat transfer. Excess scale will also reduce the flow cross-section of the cooling water, reduce the amount of water and increase the condensing pressure. Therefore, when the quality of the cooling water used is poor, the cooling water pipeline should be cleaned at least once a year to remove scale and other dirt in the pipeline.

5. Refrigerant filling
   If there is no other special reason, the general INTEGRATED VENDING MACHINE REFRIGERATION UNIT will not produce a large amount of leakage. If a certain amount of refrigerant leaks due to improper use of INTEGRATED VENDING MACHINE REFRIGERATION UNIT or maintenance, the refrigerant must be added again. When filling the refrigerant, please pay attention to the type of refrigerant used in INTEGRATED VENDING MACHINE REFRIGERATION UNIT.
