Better power supply quality, system diagnostics, humidity control, energy savings, accurate temperature control, less noise, process safety, greater comfort.
Inverter compressor technology offers new opportunities for air conditioning systems, first of all in terms of energy efficient buildings, reduced energy consumption and lower running costs.
Additionally, the technology improves power factor leading to better power supply quality as well as better system diagnostics and open communication protocols which facilitate servicing.
Continuous adaptation to cooling demand provides higher energy savings and accurate temperature control.
The compressor matches power input with cooling capacity. The unit copes effectively with changes in temperature and runs at partial load which can represent over 30% reduction in the energy bill every year compared to a fixed speed or mechanically modulated compressor. The stable temperature control secures the processes in an optimum way and provides greater comfort. All in all, this means energy efficiency in buildings.
The capacity modulation attenuates power demand peaks which also contribute to increasing the grid reliability and quality of power supplied.
The soft start control leads to a near zero inrush current and improves EER:
Additional benefits are of inverter compressors are:
On top of the standard benefits for all inverter compressors and technology, Danfoss Commercial Compressors has prequalified inverter compressors and drives designed to work together.
This adds to the long list of benefits to manufacturers, consulting engineers and end-users in terms of:

Typical load profile in a building
Only a few percentages of operations are at full load in a building. HVAC systems are designed for peak conditions (right side of the graph). These conditions are not those conditions in which the equipment will operate most of the time. This graph represents typical annual climate data and hours of run time (% of year) for each condition.
