Research On Residential Buildings Heating Suitability Climate Zones Of Hot Summer And Cold Winter Zone

Problems in hot summer and cold winter zone heating is due to historical issues,China’s north-south dividing line formed by now, this problem because of the economicbase and the living conditions continue to improve and has attracted more and moreattention. At present, hot summer and cold winter region residential indoor thermalenvironment in winter construction and heating characteristics, can be summarized as:lower indoor temperature, relative humidity is too high, excessive ventilation heat loss,as well as the building envelope insulation performance is poor, the indoor and outdoortemperature difference is small, split heating efficiency is low and not comfortableaspects.Content and solve the problem of the main research of the paper has a few:First of all, through the study on basic data analysis method to determine theexisting, living in hot summer and cold winter area building critical indexSecond, based on thermal comfort theory, analysis of the current situation of theindoor thermal environment of residential buildings in hot summer and cold winter area,as well as the air temperature, relative humidity, radiation, air flow rate, metabolic rate,clothing six the impact of thermal comfort factor. Summarize the characteristics of thewinter indoor thermal environment in hot summer and cold winter area, evaluate thesuitability of winter heating.Third, with room heat balance theory, based on steady heat transfer calculation anddynamic simulation of two methods of calculation, calculation models of differenttypical indoor residential city climate conditions, external temperature difference.Analysis of the influence of climate factors and indoor and outdoor temperaturedifference. Fourth, to the local climate conditions as the basis, first determine the heatingdesign suitable indoor heating value, and critical value, and then calculated according tothe solar radiation level of temperature difference between indoor and outdoor, thecritical temperature, heating time and heating degree-days determined values, calculateand determine the outdoor heating and air conditioning parameters.Finally, summarize and analyze the characteristics of heating period, heatingsuitability evaluation around, determinants of.
