Performance Analysis of Evacuated Tube Solar Collector for Residential Heating in Mongolia
Abstract
This paper presents initial result of measurement and experimental work in smoky and dusty location of Ger district, Ulaanbaatar Mongolia, as well as some problems while using the solar water heating system for residential heating in Mongolian harsh and cold climate condition. By this research, the measurement devices were placed on the forced circulation evacuated tube solar collector system installed on the top of the residential house then the measurement had been done from December to April for last two years. As a result of this study, the average collector efficiency was 65.7 % and the system efficiency was 31.5 % in real condition during for the four months of measurements.
