During the adjustment process, the compression The machine is always running, but the speed has changed, ...
  • Samsung Central Air Conditioning Repair Center talks about whether the air conditioner is fixed frequency or frequency conversion?
    We mainly analyze from the three aspects that everyone is most concerned about. 1. Energy-saving issues are life. Of course, energy-saving is the main factor in buying household appliances, which one saves money and which one. In theory, inverter air conditioners are more energy efficient than fixed frequency, but I don't think I can save them when I buy inverter air conditioners. I believe that many families are often reluctant to turn on the air conditioner in the summer. They can only turn it on when it is very hot.

  • Why do Samsung central inverter air conditioners need to be evacuated?
    1. Drain the air and nitrogen from the pipe to reach the vacuum state. 2. Vacuum drying can eliminate water in the system. At one atmospheric pressure, the boiling point of water is 100 ° C, but with the increase of the vacuum using a vacuum pump, the boiling point decreases rapidly. If the boiling point drops below ambient temperature, the water in the pipe will evaporate. When the degree of vacuum is absolute pressure is Okgf / cm. When the gauge pressure is -1kgf / cm2, the water in the system can be completely evaporated. If there is moisture in the system, it will produce chemical reactions that affect the refrigeration cycle system, and will also ...
