Data for Simulator testing of evacuated flat plate solar collectors for industrial heat and building integration Roger W. Moss (24850936) Paul Henshall (7041101) Farid Arya (1390246) G. S. F. Shire (24766369) Philip C. Eames (7149314) T. Hyde (24766090) Solar thermal energy -- Industrial applications Migrated from ePrints The concept of an evacuated flat plate collector was proposed over 40 years ago but, despite its professed advantages, very few manufacturers have developed commercial versions. This paper demonstrates the reduction in heat loss coefficient and increase in efficiency resulting from evacuating a flat plate collector: it is hoped that these results will stimulate interest in the concept. Evacuated tubes are now mass-produced in large numbers; evacuated flat plate collectors could in principle replace these tubes if the technical difficulties in creating extended metal-glass seals can be overcome. The experimental experiences described here should indicate targets for future research.<br><br>General note about code and data: (1) Collector test results have been saved as a structure in a Matlab file (effectively a small database) FMtests.mat (FM=February - March, originally), also summarised in an Excel sheet. Each test typically lasted most of a day and is split into sub - sections (“parts”) for each condition, e.g. illumination level. Each part was curve - fitted to remove noise and obtain mean or end - point values for temperature, heat flux etc, e.g. part(2).ifit(3).... The structure in FMtests.mat is written and read using the function savepoint . (2) Raw data f iles are included in ./Data for complet eness but are unlikely to be useful: the initial generation of the values in FMtests.mat was a painstaking and time - consuming task. Each data file such as RWM160609c.mat (third data file on 9/6/2016) is analysed by a script file e.g. test 160609c2.m (“2” i s just latest version). The script files are designed to be run in sections (highlight & evaluate). 2018-02-23T00:00:00Z Dataset Dataset 10.82444/warw.33748309.v1 https://figshare.com/articles/dataset/Data_for_Simulator_testing_of_evacuated_flat_plate_solar_collectors_for_industrial_heat_and_building_integration/33748309 CC BY 4.0
