The DC inverter is introduced to heat pump water heater system. Exchanger and evaporator mathematical equations are proposed to describe the compressor. The double PI closed-loop strategy is utilized to control inverter heater system. Optimal parameters are verified using experimental methods for measuring heat transfer performance. The refrigerant charge quantity is optimized by the model and experimental data. The optimal value is 3.6 kg. Taking into account the influence of the energy efficiency ratio, output heating and output water on the system performance, the optimal length of capillary tube is 0.65 mm for DC inverter heat pump water heater system.
