A digital scroll compressor uses an electronic control system to manage the compressor's operation, while an inverter driven scroll compressor uses a variable frequency drive to adjust the compressor's speed. This allows the inverter driven compressor to have a wider range of capacity control and can lead to energy savings.
In most cases, an inverter driven scroll compressor is more energy efficient than a digital scroll compressor. This is because the variable frequency drive allows the compressor to adjust its speed and power consumption based on the cooling demand, resulting in less energy waste.
Both digital scroll and inverter driven scroll compressors require regular maintenance to ensure their optimal performance. However, the inverter driven compressor may require more frequent maintenance due to its more complex electronic control system.
The inverter driven scroll compressor is generally preferred for high-demand cooling applications. This is because it can adjust its speed and capacity to meet the cooling demand, while a digital scroll compressor has a limited number of stages and may struggle to keep up with high cooling demands.
In general, inverter driven scroll compressors are more expensive than digital scroll compressors due to their more complex electronic control system. However, the energy savings and improved performance of the inverter driven compressor may make it a better long-term investment.
