Radiant Panel

A radiant panel supplies heat directly to the floor or to panels in the wall or ceiling.

Required Objects

The radiant panel must have the following properties.

• It must be connected to a hot water loop.
• It must be connected to a chilled water loop.
• It must be attached to a conditioned zone.

Design Assumptions

• The radiant panel is modeled as a four pipe fan coil with no fan power at the moment.

Property	Value	Notes
Cooling discharge air temperature	17°C	This is passive air movement.
Heating discharge air temperature	29.44°C	This is passive air movement.

Cooling Coil

The cooling coil has the following assumptions.

Property	Value	Notes
Coil entering air temperature	N/A	Mix of air system and induced zone temperature.
Design coil leaving air temperature	17°C	It is on the colder side of discharge temperatures.
Chilled water design inlet temperature	N/A	Set by the chilled water loop.
Chilled water design outlet temperature	N/A	Set by the chilled water loop.

Heating Coil

The heating coil has the following assumptions.

Property	Value	Notes
Coil entering air temperature	N/A	Mix of air system and induced zone temperature.
Design coil leaving air temperature	29.44°C
Hot water design inlet temperature	N/A	Set by the hot water loop.
Hot water design outlet temperature	N/A	Set by the hot water loop.
