Validation model for FlatPlate
Information
This model was used to validate the
Buildings.Fluid.SolarCollectors.ASHRAE93 solar collector model
against TRNSYS data. Data files are used to ensure that the
Buildings.Fluid.SolarCollectors.ASHRAE93 solar collector model and
the TRNSYS model use the same inlet and weather conditions. The
solar collector model must reference the
Buildings.Fluid.SolarCollectors.Data.GlazedFlatPlate.FP_TRNSYSValidation
data record when comparing model results to the stored TRNSYS results.

Example showing use of the flat plate solar collector in a complete solar thermal system
Information
This example shows how several different models can be combined to create
an entire solar water heating system. The
Buildings.Fluid.Storage.StratifiedEnhancedInternalHex (tan) model is
used to represent the tank filled with hot water. A loop, powered by a pump
(
Buildings.Fluid.Movers.FlowMachine_m_flow, pum), passes the water
through an expansion tank
(
Buildings.Fluid.Storage.ExpansionVessel, exp), a temperature sensor
(
Buildings.Fluid.Sensors.TemperatureTwoPort, TIn), the solar collector
(
Buildings.Fluid.SolarCollectors.ASHRAE93, solCol) and a second temperature
sensor
(
Buildings.Fluid.Sensors.TemperatureTwoPort, TOut) before re-entering the
tank.
The solar collector is connected to the weather model
(
Buildings.BoundaryConditions.WeatherData.ReaderTMY3, weaDat) which passes
information for the San Francisco, CA, USA climate. This information is used to
identify both the heat gain in the water from the sun and the heat loss to the
ambient conditions.
The flow rate through the pump is controlled by a solar pump controller model
(
Buildings.Fluid.SolarCollectors.Controls.SolarPumpController, pumCon) and a
gain model. The controller outputs a binary on (1) / off (0) signal. The on/off
signal is passed through the gain model, multiplying by 0.04, to represent a
flow rate of 0.04 kg/s when the pump is active.
The heat ports for the tank are connected to an ambient temperature of 20
degrees C representing the temperature of the room the tank is stored in.
bou1 (
Buildings.Fluid.Sources.MassFlowSource_T) provides a constant mass flow
rate for a hot water draw while bou
(
Buildings.Fluid.Sources.Boundary_pT) provides a boundary
condition for the outlet of the draw.
