Hi, I am getting poor results by using Type2b to control a solar collector, since it operates at some time-steps when it shouldn’t (for example, when the temperature coming out from the tank is higher than the SC output temperature,
effectively cooling the tank). I tried to switch to Type 2a, and changed to Powell’s method, but the model won’t run since I am using an Aquastat in a different part of the model, and that one requires the Successive substitution method. Has anyone faced this problem before? I am using a 0.25 hour resolution. In advance, thanks for your help. Best regards, Benjamin Manrique D. |
