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).
In EnergyPlus solar collectors are components that are connected to a solar plant loop. A solar heating system can be constructed with a combination of solar collectors, pumps, and hot water tanks. The EnergyPlus model is based on the equations found in the ASHRAE standards and Duffie and Beckman (1991).
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.
Select a building solar collector surface o define the gross area, position, orientation and tilt of the collector. Check this option to identify this Solar collector as the one to be used as a reference point for the differential thermostat selected on the Solar loop dialog.
A Solar collector performance template which defines the thermal and optical properties of the collector. DesignBuilder provides a database of Solar collector templates containing the thermal and optical performance parameters for a single collector module.
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.
