Study On The Applicable Technology Of Clean Heating In Low-energy Rural Houses In Cold Area

In rural areas in cold regions of China,winter temperatures are low and the heating season is longer.Central heating systems with strong environmental protection are not suitable for rural areas with low density of buildings for popularization.However,traditional heating methods in rural areas are not only wasteful.A large amount of primary energy and damage to the ecological environment will also cause indoor air pollution and pose a threat to the safety of farmers.Therefore,the design of a sustainable heating system for rural households and the provision of a self-selection strategy for a clean heating program are of great significance to rural heating in cold regions of China.In this paper,the basic situation of the countryside in Shandong,a major agricultural province in the cold region,the layout of the building,the construction of the enclosure structure,the heating status in the heating season,and the use of clean energy in the countryside were conducted through data access,field visits,questionnaire surveys,and on-site testing.In-depth investigation and summarization of the rural areas in Shandong rural areas related to heating problems.In terms of research basis,this paper will design and analyze the three major components of the clean heating system: farm house building,heating source and heating end.In the aspect of farm house construction,a model of a typical farm house in a cold region represented by Shandong Province was established through research and sorting,and a low-energy optimized design of the farm house was performed.The heat load of the house was analyzed and simulated using Designbuilder software.In the aspect of heating sources,the solar energy source,auxiliary heat source,air source heat pump heat source,solidified biomass heat source,and gas boiler heat source were selected as applicable heating technologies in rural areas in cold regions and technical analysis was conducted.At the end of heating,rural applicabilityoptimization design and technical analysis were conducted for the three heating ends of existing radiators,low-temperature floor radiation,and counter-current flow.Through the three basic elements of clean heating: the rationalization of the combination of rural housing construction,heating heat source and heating end,a contrastive plan was established with the three subjects as the research object,and the use habits of rural residents and the combination of rural housing equipment were taken into full consideration.Prerequisites to complete the design of clean heating program.On the basis of theoretical analysis,simulation calculation,and data and information processing,the applicability analysis of the three elements of clean heating system from room temperature construction ability and economy was carried out,and the selection strategy of rural clean heating was proposed.This article aims to fully consider the climate characteristics of cold regions,living habits of farmers,building characteristics of farmers and other elements,and put forward the development and design of clean heating technology suitable for low-energy rural housing construction in cold regions.Based on the effects of heating and economy,the research on the application of clean heating technology in cold regions is hoped to improve the heating energy quality of farmers in the region,improve the thermal comfort and air quality of the rural households in the heating season,and select individualities for different situations.The theory of clean heating provides a theoretical reference.
