The Research On The Design Of Solar Water Heating System Integration With High-rise Apartment In Dalian

At present, major urban construction land is very tight. High-rise residential become the mainstream of the urban residential, not except Dalian. Since2000, high-rise residential in the urban have rapidly developed. Although application of solar energy on the low-rise and multi-storey residential have been more extensive and more mature in China, there are a lot of parti cularity in architectural style, functional layout and structural design of high-rise residential, c ompared to low-rise and multi-storey residential. There are still many problems and difficultie s in the integration with solar water heating systems. In this paper, the solar water heating syst ems for high-rise residential in Dalian area were discussed.The main problems in the design of domestic solar water heating systems and high-rise r esidential integration were pointed in this paper, such as limited roof area, no considering in t he beginning of the architectural design, unreasonable planning of the collector water supply s ystem. So the aim of the paper was to study the integration of design methods and strategies. The cases which integrated the design of solar water heating system with high-rise residential at home and abroad were analyzed, and design ideas and methods were extracted. And then, i n view of natural and geographical conditions of the Dalian, distribution of solar energy resou rces, model cases of applications of solar hot water system for the local residential constructio n were investigated. In the end, a survey report was formed by way of questionnaires and on-t he-spot investigation. High-rise residential layout characteristics of Dalian area, sunlight ordin ance, status and change trends of orientation spacing were analyzed. Sunshine duration and el evation distribution of the plate and tower high-rise residential in different conditions were an alyzed by sunshine simulation software. The feasibility of placing the collectors at the south e levation of buildings was studied. Above theoretical analysis and feasibility studies, Selected for the construction component parts suitable for the integration of Dalian area high-rise residential solar water heating systems targeted design, described respectively from the three angles of conventional design techniques, functional adaptation and geographical suitability of design and test design; attempt to explore the high-levelvarious combinations of form and possible ways of integration of residential solar systems.
