Abstract: In this paper, the liquid-separation condensation, which is a heat transfer enhancement technology, is applied to the plate condenser. The physical and mathematical models of the liquid-separation plate condenser with multi-path are established. The thermal performance of four plate condensers (conventional type, two-path, three-path and four-path) having the same heat transfer area is compared by using performance evaluation parameters (η). The results show that the performance of liquid-separation plate condenser increases with the path numbers. The η can reach up to 1.12. In the conventional plate condenser, the heat transfer coefficient in the later path is lower than that in the previous path, whereas it is opposite in the liquid-separation plate condenser. Under the same working condition, the heat load and vapor quality at the outlet of liquid-separation plate condenser are higher than these of the conventional plate condenser.

Key words: liquid-vapor separation plate condenser, multi-path, performance evaluation parameters, heat transfer coefficient
