High Efficiency
High Eciency Inverter Compressor
Large-power Startup and Low-power Operation
The DC inverter compressor will run cooling at the largest power input and largest airflow each time it is started until
the set temperature is approached. Then, it runs at a low speed and low power input, which will not only keep the
temperature from fluctuating, but will also avoid frequent starting and stopping of the compressor, in result, prolonging
its service life.

as an example, the air conditioning time of the DC inverter unit is 6-10 minutes shorter then that
of the non-inverter one. After the set temperature is reached, the DC inverter compressor will run using 90% less energy
then the non-inverter compressor, therefore resulting in temperature loss being controlled and keeping temperatures at
steady settings. Which cuts down on the electrical consumption and greatly improves the energy eciency.
High Eciency PMSM
As for the DC inverter compressor with the permanent magnetic synchronous motor (PMSM), there is no current
through the motor rotor, no eddy current loss, and little heat produced, which means less ineective power loss so
that the motor’s efficiency is improved and the power input is reduced greatly.
