    6. Using and MITSUBISHI Rotary Twin-Cylinder DC Inverter Compressor and HITACHI DC Inverter EVI System Scroll Compressor, Green Environment, High-Efficiency,Providing Wonderful Performance and Reliability.

    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.

    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
