Low temperature radiant floor heating system design茕桢广鳓鯡选块网羈泪。
Abstract: With the continuous improvement of living standards,when home decorating the heating radiator they have to add a radiator cover,which not only affects the heat dissipation,but also will lose the most valuable room space. Low temperature hot water radiant floor heating comfort with its unique energy saving,easy to household heat metering and help decorate,indoor temperature distribution,and improve the noise floor,to overcome the many shortcomings of heating radiator,and has been using extensively in engineering. Low-temperature radiant floor heating occurred in northern Europe in the last century 30s,with the development of new materials in the Plastics Industry for the radiant floor heating to provide a reliable guarantee. This article describes the principle of low temperature radiant floor heating system,analyzes the characteristics of low temperature radiant floor heating systems and advantages,and has designed a low-temperature radiant floor heating system for an office in Hangzhou area. The design includes heating system heat load calculation,calculation of coil parameters,thermodynamic calculation,hydraulic calculation,the heat source selection and system layout,etc.,which buried underground using PE-X pipe with snake coil-type arrangement,and the heating medium is the air source heat pump water heater .And in the end an economical analyses has been made for the low temperature radiant floor heating system.鹅娅尽損鹌惨歷茏鴛賴。 Keywords: low-temperature radiant floor heating; thermodynamic calculation; hydraulic calculation; air source heat pump water heater籟丛妈羥为贍偾蛏练淨。 Classification: TU832
