6 FAQs about [Solar collector selection calculation]
What is the mathematical model of solar collector?
The mathematical model of solar collector consists of external energy balance of absorber (heat transfer from absorber surface to ambient environment) and internal energy balance of absorber (heat transfer from absorber surface into heat transfer fluid).
How to optimize solar collector construction?
The use of the design tool for parametric analysis coupled with economical calculations can provide optimisation of the solar collector construction. Heat loss from absorber through glazing to ambient environment for solar collectors with low-emissive absorber (emittance 0.05) is around 75 % of overall collector heat loss.
How does a solar collector work?
Theoretical calculations As it was noticed, only a part of solar insolation on the surface of a collector is transferred into heat. The amount of this energy depends on the type of the solar collector and meteorological conditions of the place, where the collector is working.
What are the levels of a solar collector?
The solar collector is defined by means of main levels: glazing exterior surface (p1), glazing interior surface (p2), absorber (abs), frame interior surface (z2) and frame exterior surface (z1). These levels are schematically outlined in Fig. 1.
What is the difference between a solar collector and a reference collector?
Geometrical and physical properties of solar collector elements are taken identical with reference collector except the variable fin width. Collector performance with three values of fin width (50, 125, 200 mm) has been compared. The solar collector with narrow fins has a better heat removal
How does a solar collector produce heat energy?
Only a part of solar radiation striking the solar collector is converted into heat energy. The value and the intensity of solar insolation over a year, strongly depend on the latitude and weather conditions of the place. The heat energy produced by a solar collector depends on the type and design of the collector.
