Automatic Control System

The whole automation system is mainly divided into two parts: one part is the hardware equipments consisted of all kinds of devices used in the testing system; the other part is the software program based on Labview language. I/O device is used to connect hardware with software. Through the automation system the test system need […]

Measured sequences used for validation purposes

The comparison of experimental and calculated instantaneous power results, obtained after the different approaches presented in the previous section, is based on instantaneous efficiency measurements for a CPC collector (C = 1.72), as well as on their corresponding steady-state and dynamic efficiency curve parameters. The measurements were made at the Institute for Thermodynamics and Thermal […]

A Long Term Test of Differently Designed Evacuated Tubular Collectors

J. Fan*, J. Dragsted, S. Furbo Department of Civil Engineering, Technical University of Denmark, Brovej 118, DK 2800, Kgs. Lyngby, DenmarkCorresponding Author, iif@byg. dtu. dkAbstract During three years seven differently designed evacuated tubular collectors (ETCs) utilizing solar radiation from all directions have been investigated experimentally. The evacuated tubular solar collectors investigated include one SLL all-glass […]

Set up of the test facility

One aim of the newly developed all-in-one test facility is to combine all three test methods in a single test facility. This test facility must be able to fulfil all requirements and qualifications result­ing from the above mentioned standards. The housing of the test facility is a conventional 20 foot office container. In this container […]
