How to confirm whether the air-cooled screw unit is frequency conversion

Confirm whether the air-cooled screw unit is frequency conversion, you can use the following methods:

check the model identification: the model of the variable frequency air-cooled screw unit usually contains the words "frequency conversion" or "BP.

Observe the external machine: the external machine of the variable frequency air-cooled screw unit is usually larger than the external machine of the traditional fixed frequency unit, because the variable frequency unit needs more heat dissipation space. In addition, the external machine of the frequency conversion unit will also be equipped with a frequency converter to control the speed of the compressor, so as to achieve more accurate temperature control.

Check the energy efficiency label: The variable frequency air-cooled screw unit usually has a higher energy efficiency ratio, and a higher energy efficiency level will be displayed on the energy efficiency label. For example, a variable frequency unit may display an energy efficiency rating of level 1 or level 2, while a fixed frequency unit may only achieve level 3 or level 4 energy efficiency.

Understand the functional characteristics: The variable frequency air-cooled screw unit has a variety of intelligent functions, such as automatic adjustment of indoor temperature, intelligent dehumidification, intelligent mute, etc. The fixed frequency unit may not have these intelligent functions, or the function is relatively simple.

To sum up, by observing the model identification, external machine, energy efficiency identification and understanding the functional characteristics and other aspects, we can more accurately determine whether the air-cooled screw unit is a frequency conversion unit.

Please note that the above method is not absolutely accurate, because different manufacturers and products may be different. At the time of purchase, it is recommended to consult the manufacturer or sales staff to obtain the most accurate information.
