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
Inverter heat pumps reduce cycling to keep your family more comfortable and to eliminate cold drafts. By minimizing energy lost during cycling, they also improve your home's overall energy efficiency and reduce energy consumption. This not only helps keep your heating and cooling bills in check but also protects the environment from the effects of air pollution and greenhouse gas emissions.
In some heat pumps, the inverter technology may also reduce operating noise and extend the life of the compressor and other system components.
