Establishment and Application of the Energy Consumption Model for a Novel Dual-Suction Compressor
In this study, a mathematical model of the dual suction compressor which can be applied to the household temperature and humidity independent control air conditioning system was established. The parameters of R410A were calculated with the help of REFPROP. The power consumptions of the dual suction compressor at different frequencies were calculated at different evaporation and condensing temperatures. Comparing with the experimental data, relative errors within \(\pm10\)% between the simulated and experimental values of compressor power consumption occurred under various conditions, suggesting that the accuracy of the established energy consumption model met the requirements of engineering application. With the established model, the influence of different evaporation and condensing temperatures on the compressor power consumption and energy efficiency were simulated. The results showed that when keeping the evaporation temperature and condensing temperature of the LT side as a constant, the compressor power consumption decreased by 3.2% with each 1°C increment of the average evaporation temperature of the HT side. On the other hand, when the HT side evaporation temperature and condensing temperature was maintained as a constant, increased by 10% and the compressor power consumption decreased by 1.7% with each 1°C increment of the average LT side evaporation temperature. The verified model can be applied to guide the optimization of evaporation and condensing temperatures in the future practical application of dual suction compressor in temperature and humidity independent control air conditioning system.
