摘要

热管换热器广泛应用于空调新风系统来降低空调及建筑能耗。结合某空调新风一体机实际运行工况，开发出一款基于三维变形管的新型高效能量回收器，对其不同参数能量回收效果进行计算和模拟分析以确定最优参数，并对改造前后的室内气流组织进行模拟研究。结果表明：在夏季工况下，采用螺距为60 mm、长短轴比为1.3的三维变形管，且能量回收器进出风均为方形开口时，能量回收率最大，可达77.11%；达到同样制冷效果的前提下，比普通空调器节约电耗近35%，节能效果显著。此外，增设能量回收器后，由于存在能量回收，室内温度波动小，人体的舒适性更高。

Abstract

Under the background of "double carbon"

heat pipe heat exchangers are widely used in fresh air systems to reduce the energy consumption of air conditioning systems in buildings. In this study

combined with the actual operating conditions of an air conditioning and fresh air integrated machine

a new type of high-efficiency energy recovery device based on a three-dimensional distorted tube is developed. The energy recovery effects of different parameters are calculated and simulated to determine the optimal parameters

and the indoor air distributions before and after the retrofit are simulated. During the summer season

the three-dimensional distorted tube with a pitch of 60 mm and a long axis to short axis ratio of 1.3 is used

along with a square opening for the air inlet and outlet of the energy recovery device

resulting in the highest energy recovery rate of 77.11%. Under the premise of achieving the same refrigeration effect

compared to the baseline air conditioners

remarkably

it saves nearly 35% of the power consumption. In addition

after the addition of the energy recovery device

the indoor temperature fluctuation becomes small

and the thermal comfort is improved.
