Expertise Required:
Friendly use through step-by-step guidelines, these tutorials will help you when calculating solar thermar water heating systems:
Audience:
Students, professionals and people with interes in calculating Solar Thermal Water Heating Systems and its energy production in order to decide whether to invest or not in this technology.
Input:
- The geographical location of the facility.
- The Monthly solar radiation on the horizontal plane.
- The temperature of the water supply network.
- The average daytime temperature.
- Roof features: Deviation from South (if located in Northern Hemisphere) and Slope.
- Type of collector's integration on the building.
- The profile of the obstacles that can cast shadows on the solar collectors.
- The average hot water consumption at 60 ºC per end-user and day
- The months scheduled for the STWH operation within one year
- The hot water consumption profiles classified by Month, week and day
- Type and prices of fuel consumption before and after STWH installation
- Collector's performance.
- Parameters to place properly the solar collectors on the (sloped) roof
- Features of the main equipments (exchangers , primary and secondary loops, solar storage tank, etc.)
- Solar Fraction
- Cost Ratios: Implementation, maintenance, monitoring, wardening insurance, etc.
Output:
- Solar collectors' optimal position to maximize the received solar radiation during the operation period taking in account the slope and the orientation of the roof where the collectors are located.
- Losses associated to orientation and tilt.
- Solar chart according to the geographical location
- Shadding losses due to overlaying the solar chart and the surrounding obstacles
- Sizing of the main equipments (plate heat exchanger, primary and secondary loops, solar storage tank, etc.) to achieve the Solar Fraction.
- Recalculating the annual Solar Fraction when features of the main equipments are modified
- Energy production results: Annual and monthly Solar Fraction, Average annual efficiency, thermal energy demanded, solar energy contribution and excess of solar energy generated.
- Profitability indicators according to static and dynamic calculation methods
Besides, the profitability report, online issued in PDF format and editable format, shows:
- Purpose and scope
- Description of the STWH.
- The annual and monthly radiation received on the solar collector according to his tilt and orientation.
- Annual losses: shading, orientation and tilt
- Monthly shading losses
- Total weight in full load over the roof due to the solar collectors.
- Total required area of (sloped) roof (including necessary gaps to avoid auto-shading)
- Flow, pressure drop, and power of the hydraulic pumps in primary and secondary loops.
- Percentage solution of antifreeze required in the primaryloop and its boiling and freezing point.
- Compliance with regulations.
- Performance charts.
- Cash-flow curve according to income and expenditure for 25 years.
