The digital scroll condensing unit adopts a digital scroll compressor. The digital scroll compressor runs continuously at full speed, while the displacement will be changed by raising and lowering the movable scroll to achieve the different cooling capacity.
The variable speed condensing unit adopts BLDC inverter compressor. The inverter compressor is actually composed of two parts, one is the inverter controller, and the other is the compressor. The principle of the inverter compressor is to convert the alternating current in the grid into a square wave pulse output. By adjusting the frequency of the square wave pulse (that is, adjusting the duty cycle), the speed of the compressor motor can be controlled. The higher the frequency, the higher the speed. Another advantage of the variable speed controller is that the starting current is small, which will not cause a large impact on the power grid.
