Study On Rural House Technology System Design Based On Renewable Energy Utilization

A large amount of energy is consumed during construction and usage of rural house in our country. Today under the condition that global energy resources faces unparalleled stress, this problem becomes more outstanding. This paper is prepared under the background of quickening the construction of new socialist countryside and advancing the utilization of renewable energy in China. Based on the subtopic Key Technology Research and Product Development on Energy Saving for Rural House [2006BAJ04A05'] of Key Technology Research and Demonstration for Rural Well-off House - project of National Key Technology R&D Program during the 11th Five-Year Plan Period, this paper is on the basis of plenty of actual investigation and tests in Korea, Netherlands and China. It studies renewable energy technology system and rural house design to provide theoretical and practical basis for the construction of rural house in the northeastern China, with the target to utilize renewable energy technology.This paper first puts forward self-coupling, symbiosis coupling and response coupling theory through thoroughly understanding energy substitution theory, technology system theory and coupling theory, philosophically based on Confucianism"Everything-As-One", with the way of thinking Nature, Universal One, Nature and Man in One, life synesthesia and harmony, as well as the concept of symbiosis and response in biological theory. Based on house system's architectural and technological elements, it gives response coupling mode of solar energy utilization technology system and house system, continuous symbiosis coupling mode of biomass energy utilization technology system and house system, integrative symbiosis coupling mode of comprehensive energy utilization technology system and house system, coupling design mode of other new energy utilization technology system and house system by using coupling interface. Then, it couples traditional heated kang construction idea with fire pit heating technology to form a new heating installation on the basis of biomass energy utilization and puts forward heat transfer and operation strategy for the self-coupling design of fire pit technology system; it puts forward continuous symbiosis strategy of fire pit technology and heated kang context, heated kang structure, energy saving stove and plane layout based on symbiosis principle and relevant verifying tests and economic evaluation are conducted. Solar energy pebble heat storage heating plant is designed based on solar energy utilization and this paper studies its self-coupling strategy and design strategy of response coupling of this heating plant and rural house system; response coupling of enclosure system interface adopts design strategy of material response and enclosure structure response; indoor system interface coupling is designed to adopt kang structure response and indoor layout response coupling strategy and relevant verifying tests and economic evaluation are conducted. Based on utilization of solar energy and biomass energy, Liaoshen series solar greenhouse is designed and studied in accordance with self-coupling design theory; it also discusses design strategy of greenhouse and biogas tank response coupling in accordance with response theory and conducts tests to verify its thermal insulation performance. Finally, based on the symbiosis and response principle, it discusses response and integrative symbiosis coupling design strategy on land system interface, enclosure system interface, mechanical system interface and structure system interface for comprehensive energy utilization technology system and rural house, as well as takes Five-in-one rural house in Faku for example to set forth how to apply coupling design strategy and applicable technology during design.The above problems are studied mainly through cross study of multi-discipline such as architecture, biology, system science, energy etc., combination of theory and empirical study, combination of qualitative and quantitative study and comprehensive study.Based on renewable energy utilization, this paper establishes theory framework for rural house coupling design, builds coupling design mode and puts forward specific coupling design strategy to provide scientific viewpoint and visual angle for thoroughly understanding the new rural house design; fire pit technology, pebble heat storage heating technology, greenhouse technology and comprehensive energy utilization technology have great practical significance for mitigating energy crisis and resolving many problems available in rural area, such as bath problem, lower indoor temperature in winter, lower biogas output, difficult vegetable supply and other problems.
