Screw compressor does not work, how to do Yantai screw compressor repair

One of the reasons for air conditioning not cooling: Freon is not enough (commonly known as "snow species" is not enough) When the ambient temperature is about 35 degrees Celsius, low pressure 0.45MP2, high pressure 2.5MP or more 3, static pressure 1.1-1.2MP

This is a normal situation and is usually seen in old air conditioners that have been used for three to four years. The air conditioner did not completely cool, but the cooling effect was reduced. This is because old-fashioned air conditioners use Freon as a refrigerant and will evaporate for a long time. Therefore, users only need to add a little to the regular air conditioning repair point. In addition, it does not rule out the problem of improper installation and Freon leakage and the machine itself. The reason why the air conditioner does not cool is the second: the power supply voltage is not enough. The normal starting voltage of the air conditioner is 220V+-10%. In China's power supply system with phase voltage of 220V and line voltage of 380V, almost all compressors above 200V can be started. When it is above 180V, 70-80% can be started. When it is above 160V, only individual can start. I personally did experiments. It is almost impossible to start below 160V. According to experience, when the temperature is above 190V, the compressor starting voltage is relatively reliable. Air conditioner does not cool the third reason: air conditioning power is not enough

The general selection principle is: 150-250W/m2 for cooling and 250-350W/m2 for heating. In addition, factors such as space height, directional orientation, sealing performance and resident population should be considered.
