Dear Muhammad Farooq,There are a few fundamental problems with your simulation before being concerned about the tank temperature. First of all, your heat pumps and pumps do not have any controls - they are simply operating the entire year according to the *.tpf that you sent. I would recommend that you refer to the TESS GHP Example in the ".\Tess Models\Examples\GHP..." directory. Second, you are not using an online plotter device to view your inlet/outlet temperatures, flow rates, etc, thus making it very difficult to see how your system and subsystems are responding. You will likely see that your heat pump is operating outside of the desired range. Last, when you do implement controllers, your timestep is going to have to be much lower as controllers make a decison (on or off) once per timestep.Best regards,Matt Duffy----- Original Message -----From: "Muhammad Farooq" >;engr_farooq85 at yahoo.com
