Abstract


Nowadays water scarcity and energy shortages, has seriously hampered the economic and social development, thus saving water and energy become a new direction for building development. In this thesis, building water supply system for the study of life, combined with the energy situation and relevant research experience at home and abroad, to water and energy conservation purposes, the following aspects were studied: household water quota reasonable ranges, saving water appliance applications and solar water heating systems, heat pump hot water system to use, and expand economic analysis. Reasonable choice of living water quotas, designed to determine water consumption is the first step in building domestic water supply system, but also the design of the system is the first step in saving water. Based on the size of cities, water appliances degree of perfection, urban climate conditions and levels of economic development and other water quota important influencing factors, combined with the existing for each city, a local water conditions and the introduction of the standard of living water quota, get fit national reasonable under the circumstances of different water living water quota proposals range. Water apparatus is building domestic water supply system, water users directly in contact with the part of the water is also an important part. In this paper, water saving appliances domestic situation and the definition, classification, and plain water, water saving appliances and utensils used in the daily life of residents to compare the process to obtain a water-saving appliances with water saving ability, and the conclusions of affordable , the proposed new water supply system of life saving water appliances are used. Building energy hot water system is an important part of building energy-saving domestic water supply system is usually achieved through this system, and energy-efficient hot water system is to cut expenditure and the use of renewable energy sources to achieve. In this paper, common building energy water heating systems heat medium to analyze the situation, through the solar water heater and air source heat pump hot water system in the building of applied research, the focus of investment and the use of common water heater energy consumption during conditions Air source heat pump hot water system to get energy and economic conclusions. Thus, a reasonable choice of living water quota, use of water saving appliances and the use of solar energy, air source heat pumps and other renewable energy hot water system is building living water supply system effective way of saving water and energy.
