Performance Evaluation of an Evacuated Tube Collector with a Low-Cost Diffuse Reflector

Schumann, Julian; Schiebler, Bert; Giovannetti, Federico (Basel : MDPI, 2021)

In order to increase the overall solar energy gain of evacuated tube collectors, rear‐side reflectors are used. In this way, the otherwise unused incident radiation between the tubes can be reflected back to the absorber, ...
Simulation and Evaluation of Solar Thermal Combi Systems with Direct Integration of Solar Heat into the Space Heating Loop

Glembin, Jens; Haselhorst, Thomas; Steinweg, Jan; Rockendorf, Gunter (London : Elsevier Ltd., 2016)

Usually, solar heat in combi systems is used via a buffer storage. In contrast to that, the solar collectors may be connected directly to the space heating circuit in order to store the heat in the building itself. Such a ...
A Thermal-Hydraulic Model for the Stagnation of Solar Thermal Systems with Flat-Plate Collector Arrays

Eismann, Ralph; Hummel, Sebastian; Giovannetti, Federico (Basel : MDPI, 2021)

Stagnation is the transient state of a solar thermal system under high solar irradiation where the useful solar gain is zero. Both flat-plate collectors with selective absorber coatings and vacuum-tube collectors exhibit ...
