开发了一个简化的分析模型来确定地下空气隧道的能源性能。该模型假设空中隧道-地面系统在运行几天后达到周期性和准稳态行为。该模型可以预测一天中任意时刻空气隧道沿线的气温变化。它还可以确定隧道总冷/热效应的日平均值和幅度。通过参数分析确定隧道水力直径和空气流量对隧道内地面与空气之间传热的影响。该模型根据测量数据进行验证。
A simplified analytical model is developed to determine the energy performance of an underground air tunnel. The model assumes that the air tunnel-ground system reaches periodic and quasi-steady state behavior after some days of operation. The model can predict the air temperature variation along the air tunnel for any hour of the day. It can also determine the daily mean and amplitude of the total cooling/heating effect of the tunnel. Parametric analysis is conducted to determine the effect of tunnel hydraulic diameter and air flow rate on the heat transfer between ground and air inside the tunnel. The model is validated against measured data.
