temperatures of the surface must be limited, and there are some con-
trol problems, particularly in floor panels, due to the mass of the
panel.
Radiant cooling by means of wall or ceiling panels may also be used.
Surface temperatures must be kept above the dew point; therefore,
any dehumidification required must be accomplished by other means.
In modern practice, radiant and / or convective heating or cooling is
usually a supplement to the air system and is used primarily to offset
exterior wall, roof, and radiant floor heat gains or losses.
