![]() | Partial model for exterior construction that has no window |
This is the base class that is used to model opaque constructions in the room model.
The surface azimuth is defined in Buildings.RoomsBeta.Types.Azimuth and the surface tilt is defined in Buildings.RoomsBeta.Types.Tilt
Type | Name | Default | Description |
---|---|---|---|
Area | A | Heat transfer area [m2] | |
Angle | til | Surface tilt [rad] | |
Opaque construction | |||
Area | AOpa | Heat transfer area of opaque construction [m2] | |
Generic | layers | redeclare parameter Building... | Material properties of opaque construction |
Initialization | |||
Boolean | steadyStateInitial | false | =true initializes dT(0)/dt=0, false initializes T(0) at fixed temperature using T_a_start and T_b_start |
Temperature | T_a_start | 293.15 | Initial temperature at port_a, used if steadyStateInitial = false [K] |
Temperature | T_b_start | 293.15 | Initial temperature at port_b, used if steadyStateInitial = false [K] |
Type | Name | Description |
---|---|---|
HeatPort_a | opa_a | Heat port at surface a of opaque construction |
HeatPort_b | opa_b | Heat port at surface b of opaque construction |
