The operation of central air conditioning system and the harm of scale to the system

As we all know, any water filtration machine we use will produce scales, such as drinking fountains. When scales form in the system during long-term use, it will cause great harm to the system itself. The central air conditioner is no exception.

Reason analysis of refrigeration compressor can not start or stop soon after start

1) First check the main circuit. Whether the power supply has power, whether the voltage is normal, whether the fuse has been blown due to starting overload, whether the air switch has tripped, whether the switch contacts are good, and whether the power supply is missing phase. Observe the voltmeter and ammeter when starting. When the small-scale refrigeration and air-conditioning equipment does not have an ammeter or electric meter, a multimeter or electric pen can be used to check the power supply. When the power supply voltage is too low, the compressor will not start.

How to properly use central air conditioning during the epidemic Just read this one

At the moment of the epidemic, is there a risk of cross-infection in central air conditioning? How do units reduce the risk of using central air-conditioning? Xu Wei: The prevention and control of the new crown pneumonia epidemic is currently the most important work. The correct operation of the air conditioning and ventilation system during the epidemic period of infectious diseases can effectively reduce the chance of cross infection. Due to the diverse types of buildings and the wide variety of central air conditioners,
