摘要：
To optimize the operation of heat source tower heat pump, extremum entransy loss principle was proposed and entransy loss model was established for heat source tower heat pump system based on entransy theory. The system entransy loss rate was studied under different operation conditions for system heat load fixed or input power consumption fixed by means of simulation and experiment so as to get the optimization operation conditions. The results show that relative error of entransy loss rate values between simulation and experiment is less than 9.8% which proves that the model is adequately accurate. When system heat load is 4 kW, the optimization operation condition parameters are 51 Hz for compressor frequency, 0.5 kg/s for hot water flow rate, 0.6 kg/s for solution flow rate and 1.4 kg/s for air flow rate, which leads to the maximum system entransy loss rate, minimum system input power consumption and maximum system efficiency. When system input power consumption is 2 kW, the optimization operation condition parameters are 72 Hz for compressor frequency, 0.4 kg/s for hot water flow rate, 0.5 kg/s for solution flow rate and 1.6kg/s for air flow rate, which leads to the minimum system entransy loss rate, maximum system heat load and maximum system efficiency. © 2017, Central South University Press.
