Abstract

Abstract:

In this paper， the experimental system for high mass flow density flow and heat transfer characteristics with heat back was designed and built with the wound tube heat exchanger as the test piece. The experimental system includes main test cycle circuit， cooling circuit， control system and safety ventilation system. The experimental conditions of the experimental system can cover 0.15~0.85 MPa evaporation pressure， 20~120 kg/（m²·s）mass flow density， 0~1.0 dryness and 0~10 kW/m² heat flow density. The thermodynamic model of the experimental system is constructed， and the temperature， pressure data and equipment load parameters of each node under the experimental conditions are obtained. The energy consumption of the system is analyzed and compared with the existing data. It is found that the energy consumption of the regenerative system with back heat is lower than that of the non regenerative system in each dryness. When the dryness is 0.1， the energy consumption is reduced by 75%， when the dryness is 0.5， the energy consumption is reduced by 43%， and when the dryness is 1， the energy consumption is reduced by 3%.

Key words: power engineering, engineering thermophysics, low temperature high mass flow density, back heat, energy consumption
