How Do Inverter Heat Pumps Work?
In a standard heat pump or air conditioner, a fixed-speed compressor comes on at full capacity to meet the indoor temperature requirement and then turns off once the target temperature is met. This results in peaks and valleys in both power consumption as well as inside temperature.
By contrast, inverter-driven heat pumps and air conditioners have a variable frequency drive (VFD) that incorporates an adjustable electrical inverter to control the speed of the motor, compressor, and cooling and heating output.
The inverter, or VFD, uses a rectifier to convert the incoming alternating current (ac) to direct current (dc), then uses pulse-width modulation in an electrical inverter to produce ac of a desired frequency. The variable-frequency ac drives a brushless motor, or an induction motor, as the speed of an induction motor is proportional to the frequency of the ac. The compressor can then run at different speeds
1) Faster response to variable heating and cooling loads.
2) Significantly reduced running costs (up to 50% saving) compared to non-inverter systems.
3) Improved comfort as set-point temperatures are achieved more quickly.
4) Improved maintenance of design conditions with less temperature fluctuation.
5) Eliminates voltage peaks from compressor.
6) Reduced risk of electromagnetic interference with other equipment.
