摘要

为了解重庆段长江水作为热泵冷热源的概况

对重庆段长江水温的横断面变化和时间变化进行了实测分析

并对江水的水质和水位变化进行了分析

得到长江水温在整个横断面基本恒定

而江水的夏季月平均温度在22~25℃

冬季月平均温度在11~16℃

水温日变化幅度不超过0.5℃。是一种具有良好品质的稳定的冷热源。而长江水作为水源热泵的冷热源

主要解决的水质问题是泥沙和悬浮物

在三峡库区形成后水位变化可达到30 m

因此取水方式可考虑采用浮船取水方式。

Abstract

Characteristics of smoke flow and fire spread in a patio space of a high-rise building were studied to investigate their influences on fire compartment and safety evacuation. Fire development model was established and fire scenarios were designed to simulate fire and smoke spread by CFD software numerically based on concepts of fire performance-based design in a high-rise building with double patio space

whose height are 74. 65 m and 55. 95 m

respectively. Simulation results show that in all fire scenarios

performance targets for safety evacuation for people in each floor was satisfied

if smoke was extracted naturally using the patio space. Hang walls mounted in corridors around the patio space prevent smoke flowing out smoothly

shorten the coming of the risk time and increase fire danger. Using chimney effect

it is preferred to adopt natural smoke exhaust method in a high rise building with patio space.
