In this paper, we proposed the spacing of the single-bow baffle plate to adapt to the current sea water source heat pump air conditioning system. The paper used AutoCAD platform to create a geometric model of a single bow baffle tube heat exchanger, and used the fluid analysis software Fluent to solve the heat exchanger model. The different baffle layouts were compared in the whole sea water source heat pump air conditioning system. Through the distribution of the pressure, velocity and temperature of the shell side, the optimal heat exchanger of baffle plate heat exchanger was obtained. The results show that the spacing of the baffle plate has the optimal value, and when the distance outside the baffle is equal to or slightly larger than the distance within the baffle, the comprehensive performance of the heat exchanger is better. |
