  1. Hello Chris, no, it is not possible to take GeoT*SOL for such large systems. Our focus is on small and medium size dwellings. For example, for such large systems you need a detailed calculation of the losses of the distribution system. Kind regards
  2. Hallo Dominik mit "Variante" ist die Anlage gemeint. Das ist meistens der erste Eintrag in besagtem Menü. Man kommt auch über ein Doppelklick in die weiße Fläche neben den Komponenten in den Anlagendialog. Bitte beachten: Nicht alle Anlagen unterstützen zwei Kollektorkreise. Wir sind noch dabei, die restlichen Anlagen anzupassen.
  3. Hello Ahmad, please let me answer your questions: 1. You can dimension the piping from the collectors to the tanks. Parameters are: length, diameter, losses, inside/outside of the house 2. The system's design is fixed. Multiple tanks are always connected in parallel. 3. Every manufacturer has its own special control systems. In T*SOL we compare simply the temperatures between the tank and the collector. However, you can adjust the heights of the sensors in the tank. 4. Not directly in the collectors, but the volume flow through the collector loo
  4. What exactly do you want to correct? We evaluate the fresh water from the energy balance perspective. We don't track the volume of the remaining water. Kind regards
  5. Hello C3PO, sorry c1p8, in the project report of all pool systems you get the information about - Average swimming pool temp. - Pool temperature above X °C x,x % of operating hours I see these values even in systems with aux. heating (I used system B3). Can you explain what data you want to see exactly? Maybe with an example? Kind regards
  6. Hello Kiya, in the system A1 integrated is a boiler. This boiler delivers the additional heat. Kind regards
  7. Hello a.jerez we don't support T*SOL Pro 4 anymore. Also the import of T*SOL Pro 4 - projects in T*SOL 2018 is not supported.
  8. Hi Giovanni, one restriction of the test version is, indeed, the printing of the project report. Kind regards
  9. Hi Eric, our simulation is based on intervals with a length of 6 minutes. If some temperatures or volume flows change to abruptly, we reduce the interval to 1 minute. In your scenario you have large volume flows. If the tank's volume is exchanged completedly within a simulation intervall (6 or 1 minute), we will get balance errors. The system A13 is not suited to simulate with such a small tank.
  10. Hi Couloireric could you please write down the terms belonging to the balance, from your point of view? Did you take the tank losses into account? What collector size, process heat demand and tank volume did you use? You can also attach your project (*.tsproj) file. Kind regards
  11. Hi Belal, I had a deeper look at our algorithms. The energy savings are calculated with the efficiency of the boiler. Please double click on the boiler (even if you don't use it in your simulation) and set the efficiencies all on 100 %. After this the savings equal exactly the solar contribution. There is a second way I describe below. It is inconsistent that the heating element doesn't have it's own efficiency. I issued a bug entry in our tracking system. --- The equation for the calculation of the energy savings is equal for all fuels: savings = solar con
  12. Hello Belal, sorry for the delayed answer. We had Easter holidays in Germany. Would you please give me further details? 1. What kind of system did you select (A1, A2, ...)? 2. What did you select as additional heating (boiler, gas, oil, ...)? The savings are not calculated one to one in relation to the solar gain. If you have a gas boiler for example, you have to take the effieciency of the boiler into account (around 80 to 90%). That means that the savings in Kilowatthours for the specific fuel is higher than the Kilowatthours of the solar energy contri
  13. Hallo Robert, das klingt zwar spannend, solche Kollektoren haben wir jedoch nicht in unserer Datenbank. Auch unser Simulationsmodell geht von einer einseitigen Bestrahlung aus. In den Anlagen, die zwei Kollektorfelder unterstützen, könnte man zwei Kollektoren quasi mit dem Rücken aneinanderkleben. Wahrscheinlich müssen dann noch die Kollektorkennwerte (eta, Verluste) angepasst werden.
  14. Hello Campo Solar, in T*SOL evaporation is only taken into account for the calculation of heat losses. If you have much loss of water due to evaporation you should increase the "Daily freshwater demand". I think an actual pool also doesn't have a control for the water level. Kind regards
  15. Hello saeid, W/K is Watt per Kelvin (determines the size or performance) k in kA is the heat transfer coefficient in W/(m²*K) (determines the efficiency) Both values are constructional properties of a heat exchanger. Kind Regards
