[esp-r] Re: ceiling radiation cooling system - an alternative approach

[Jon Hand]

There is an alternative to explicit plant components to represent radiant heating and/or cooling
panels.  The approach is to model the panel as a (thin) zone bounded by the metal of the panel
and with high internal heat transfer coefficients.  You then inject or extract heat from the zone
(run the simulation at a short timestep).  This is a good representation of the radiant and
convective transfer with the room.  It does not give you information about the fluid temperature
in a real system.

An example for a radiant heating model is in the folder training/rad_room_heat.  There is
a notes_rad_rooms.txt that explains the approach.

Subject: [esp-r]  ceiling radiation cooling system

Dear all,

 Hello.
 I am a student and I am using ESP-r to windows platform.
 I try to simulate the ceiling radiation cooling system by using plant
in ESP-r.
 How can I make it ?

 Regards,

 Wakana Matsumoto
