[EnergyPlus_Support] Re: Solar Collectors - Heating and DHW



Hello,

Thank You for your time.

The system I want to study is:

   - DHW.   
.........Main Heating source - Solar Collectors;
.........Auxilary heating System - Propane Boiler.

   - Heating System (Radaint Underfloor Heating)
......... Main Heating source - Propane Boiler;
..........During Daytime when DHW is not needed and solar conditions are good - Solar Collectors.

Objectives:

 Evaluating the contrubuition of the Solar Collectors, funtion of it´s area for heating and DHW;

Problem In Energy Plus: 

How to manage the control of the source side plant energy for the heating and Domestiec Hot Water Systems, considering we have a boiler in the mix.

Thanks

MN

The surface collector may need to be insulated from OD convection, etc. filled with anti-freeze as well.  These are not in the example. Since you will be using  three tanks in my suggestion, the radiant system tank is charged when ever possible, when the interfacing tank temperature is right.  The water main water should not enter this third tank.  Dr. Li
