Pressure Drop Characteristics of a Novel Active Liquid Feeding Evaporator
The application of enhanced tubes in an evaporator inevitably results in a higher pressure drop. Herein, a novel active liquid feeding evaporator is proposed to reduce the pressure drop by actively adjusting the mass flow rate and vapor quality along the flow path. Physical and mathematical models a...

| description | The application of enhanced tubes in an evaporator inevitably results in a higher pressure drop. Herein, a novel active liquid feeding evaporator is proposed to reduce the pressure drop by actively adjusting the mass flow rate and vapor quality along the flow path. Physical and mathematical models are established and experimentally verified. Comparisons of the vapor quality, mass flow rate, and pres- sure between the new and conventional evaporators are performed in the flow rate ranging from 14 g / s to 26 g / s. Results indicate that the quality and pressure drop in the conventional evaporator increased, whereas the mass flow rate decreased as the number of tubes increased under an inlet pressure of 1. 2 MPa using R410A. The inlet quality at the third path of the novel evaporator can be increased by 1. 82 times compared with that of the conventional evaporator, and the mass flow rate can be reduced by 43. 2%. Moreover, the new evaporator exhibits a lower pressure drop by 21. 5% at an inlet mass flow rate of 26 g / s. |
