Abstract:

The performance improvement of the heat exchanger has a significant impact on the improvement of the energy efficiency of the refrigeration and heat pump systems. The circuit optimization of the finned tube heat exchanger is an important research direction of heat exchanger performance improvement because of no extra cost and easy operation. This paper summarizes optimization methods and evaluation indexes of the finned tube heat exchanger circuit. The main methods are the optimization of the wind speed distribution on the air side, the flow rate on the refrigerant side, and the pipeline structure including the pipe diameter, the pipe splitting point, and the variable circuit. Other methods are the optimization based on maximization of micro-element heat transfer, based on exergy analysis with minimum irreversible loss, minimization of entropy generation, thermal resistance balance method and genetic algorithm. It is concluded that the variable flow path can meet the optimal circuit of the evaporator and the condenser at the same time, and is the best choice for the optimization of the circuit of the cooling and heating dual-purpose refrigeration and heat pump systems. In addition, the thermal resistance balance method can optimize the circuit of the evaporator and the condenser at the same time, which is the current optimization method with good applicability. The amount of heat transfer under the same pump power and thermal resistance balance are general evaluation indexes. Based on the above analysis, prospects and suggestions are put forward for the optimization method and evaluation index of the finned tube heat exchanger.
