[Bldg-sim] Solar Thermal for In Floor Radiant Heating

[Chris Jones]

The only issue with FPH is that outdoor air and exhaust fans may not 
be simulated.

>Floor Panel Heating System
>
>The Floor Panel Heating System provides heating for one or more 
>zones by circulation of heated fluid through a network of pipes 
>embedded in the floor or ceiling. A single pump, rather than the 
>primary-secondary pumping arrangement shown in the schematic, is 
>installed for single-zone systems. Space temperature in each zone is 
>controlled by varying the temperature of the fluid circulating in 
>that zone. Hourly head addition rate is determined for this system 
>exactly as for other types of systems. Pumping energy associated 
>with this system is accounted for by the PUMP attached to the 
>CIRCULATION-LOOP. The ratio of panel heat losses to panel heating 
>output must be estimated by you and entered; see the keyword 
>PANEL-HEAT-LOSS in the ZONE command). The program assumes that this 
>ratio of heat loss to heat output remains constant over the full 
>range of panel output.

>None. Note that the simulation does not account for the radiant 
>comfort aspects of panel heating; therefore, a lower heating 
>setpoint is appropriate.
