VENTS LINKED TO REMOTE HEAT DETECTORS
The well insulated room of cold ceiling is heated up by hot
floor. The room dimensions are LEN and HIG. When the air
temperature at the checkpoint of IXP and IYP grid coordinates
becomes largee than pre-determined tolerable value, TLIM, the
vents of fixed outside pressures and temperatures are opened at
the room walls. The bulk air temperature in the room is
calculated at the final stage of simulation.
Two PLANT options, namely, Global Summation and Indexed
Variable Operations are used to make the settings.
