My aim is to maintain the cold-side outlet temperature of a heat exchanger water/air at a constant value. It is connected to a stratified storage water tank that the profile of the temperature of its top is variable due to the fluctuation of the solar radiation.</font></div><div><font face="Times New Roman" size="4"><br></font></div><div><font face="Times New Roman" size="4">I have thought that the control of the water outlet flow of the tank could solve the problem, but i didn't find the appropriate components to simulate this test.</font></div><div><font face="Times New Roman" size="4"><br></font></div><div><font face="Times New Roman" size="4">Can you help me to continue my work? </font></div><div><font face="Times New Roman" size="4"><br></font></div><div><font face="Times New Roman" size="4">Thank you for your kindness.</font></div><div><font face="Times New Roman" size="4"><br></font></div><div><font face="Times New Roman" size="4">Yours sincerly.</font></div> </div></body>
