Buildings.ThermalZones.Detailed.Examples.FFD.NaturalConvectionWithControl Buildings.ThermalZones.Detailed.Examples.FFD.NaturalConvectionWithControl

A case of natural convection with feedback loop control

Buildings.ThermalZones.Detailed.Examples.FFD.NaturalConvectionWithControl

Information

This model tests the coupled simulation of Buildings.ThermalZones.Detailed.CFD with the FFD program by simulating natural convection in an empty room with a PI controller and a heater to maintain the temperature at room center to be 2ˆC.

The configuration of the simulation is the same as Buildings.ThermalZones.Detailed.Examples.FFD.Tutorial.NaturalConvection, except that a heater with PI controller is added to maintain the desired room temperature.

The temperature at the central room is sent to the PI controller as measured temperature. Based on the difference of set temperature and measured temperaure PI controller sends signal to the heater to yield the heat flow. The heat flow is then injected into the room through the heat port as convective heat flow. After receving the heat flow from Modelica, the FFD uniformly distributes it into the space.

Please note that roo.yCFD[1] is the temperature at the center of the room and roo.yCFD[2] is the velocity magnitude at the center of the room.

Figure (a) shows the velocity vectors and temperature contours in degree Celsius on the X-Z plane at Y = 0.5 m as simulated by the FFD.

Buildings.ThermalZones.Detailed.Examples.FFD.RoomOnlyExteriorWallNoWindow

Information

This model tests the coupled simulation of Buildings.ThermalZones.Detailed.CFD with the FFD program by simulating the natural convection in an empty room with only exterior walls and without windows.

Figure (a) shows the schematic of the FFD simulation. The room is 1 meter in length, width and height. The walls are exposed to the ambient environment (cold winter night in Chicago) and the insulation is very poor. The initial values are for the temperatures of the walls 20ˆC and for temperature of the air 30ˆC. All temperature drop quickly due to the heat loss. Two sensors are placed in the room center at (0.5 m, 0.5 m, 0.5 m) that measure the temperature and the velocity.

Figure (b) shows the velocity vectors and temperature contours in degree Celsius on the X-Z plane at Y = 0.5 m as simulated by the FFD. In the cold mid-night of Chicago, the temperature of the ceiling is the lowest and the temperature of the ground floor is the highest.
