6 FAQs about [Solar Collector Testing Process]
What are the characteristics of a solar collector?
They treat the solar collector as a homogeneous body and they are based on four parameters that are considered characteristic: thermal capacity, heat removal coefficient, thermal efficiency coefficient and heat loss coefficient.
Is a solar collector a fixed object?
As already mentioned, the solar collector is a non-fixed object, whose characteristic parameters depend on the operating conditions.
What are the characteristics of a heat loaded solar collector?
The heat loaded collector is characterized by a significantly higher time constant of 207.9 s, which means that the solar collector heat capacity under the load will be significantly higher than in a state with no load. The values of characteristic parameters are determined using relation Equation (19) and the model presented in Table 1 (item 30).
Which methods are used to determine the efficiency of a collector?
When considering the parameters of a collector determined during standard tests (ISO 9806 indoor) as reference values, it shall be noticed that the most similar results concerning efficiency were produced using the ISO 9806 outdoor and the ETN methods.
Is a solar collector a homogeneous body?
Most often, the solar collector was treated by researchers as a homogeneous body, and the model was based on an assumption that the thermal output of the collector in a specific period of time is a sum of the components of the effective temperature increase of the working medium [ 22, 23, 24 ].
Do solar collectors have static and dynamic properties?
The proper determination of the static and dynamic properties of a solar collector is of key significance, as they constitute a basis for the design of a solar heating installation, as well as a control system.
