摘要：

以绕管式换热器为测试件，设计搭建了带回热的大质流密度流动传热特性实验系统。该实验系统包括主测试循环回路、冷却回路、控制系统和安全通风系统。本文实验系统能够覆盖的实验工况范围如下：蒸发压力为0.15~0.85 MPa，质流密度为20~120 kg/（m2·s），干度为0~1.0，热流密度为0~10 kW/m2，温度可达-180 ℃。构建了实验系统热力学模型，获得了实验工况条件下各节点温度、压力数据和设备负荷参数。对该系统能耗进行了对比分析，研究发现，有回热系统在各个干度情况下均比无回热系统的能耗低，干度为0.1时，能耗减少75%，在干度为0.5时，能耗减少43%，在干度为1时，能耗减少3%。

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
