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

Function
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.
Advantages
1. DC Inverter compressor allows optimum adjustment to actual requirements for heating or cooling.
2. Low operating expenses resulting from a high COP according to the EN14825 standard, ranging from 4.0 to 4.7 (A7/W35).
3. Maximum heating water temperature of up to 55 °C allows installation of the heat pump in systems with radiator heating.
4. Advanced regulation unit allows connection to solar panels and use of heat generated by them.
5. Excellent comfort owing to reversible performance for both heating and cooling.
6. The heat pump operates in the temperature range from –25 °C to +43 °C, which means that it will keep your home warm during freezing winter and effi ciently cool it on hot summer days.
7. R410A is among the most environmentally friendly refrigerant gases which is not detrimental to the ozone layer.
8. Low investment costs owing to simple installation
9. Optional connection to an existing domestic hot water storage tank if an internal heat transmitter is provided in such heater. Energy-efficient domestic hot water heating – the compressor decreases the operating frequency to an optimum calculated by the control unit according to the use and the set hot water temperature.
10. Low noise owing to the axial fan and compressor unit with variable operating frequency.
The Benefits Of DC Inverter Technology
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.
