<I work on a project of a conception of a solar wood dryer and i have a problem with the control of the temperature. 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.>
The Type 670 heating coil in the TESS HVAC Library does exactly as you suggest - maintains a given air-side outlet temperature by varying (bypassing) the hot, liquid side flow rate around the heat exchanger.

Dear Madam / Sir,I work on a project of a conception of a solar wood dryer and i have a problem with the control of the temperature. 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.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.Can you help me to continue my work?Thank you for your kindness.Yours sincerly.
