Larger pipes and bigger interdistance
Extends from IDEAS.Fluid.HeatExchangers.RadiantSlab.BaseClasses.RadiantSlabChar (Record containing all parameters for a given thermally activated building system (TABS) or a floor heating system.).
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | tabs (from RadiantSlabChar) | true | = true, if the model is used for TABS (assuming no insulation layer below the slab). |
| Modelica.Units.SI.Length | T (from RadiantSlabChar) | 0.2 | Pipe spacing, limits imposed by EN 15377-3 p22 |
| Modelica.Units.SI.Length | d_a (from RadiantSlabChar) | 0.02 | External diameter of the pipe |
| Modelica.Units.SI.Length | s_r (from RadiantSlabChar) | 0.0025 | Thickness of the pipe wall |
| Modelica.Units.SI.ThermalConductivity | lambda_r (from RadiantSlabChar) | 0.35 | Thermal conductivity of the material of the pipe |
| Modelica.Units.SI.Length | S_1 (from RadiantSlabChar) | 0.1 | Thickness of the concrete/screed ABOVE the pipe layer |
| Modelica.Units.SI.Length | S_2 (from RadiantSlabChar) | 0.1 | Thickness of the concrete/screed UNDER the pipe layer |
| Modelica.Units.SI.ThermalConductivity | lambda_b (from RadiantSlabChar) | 1.8 | Thermal conductivity of the concrete or screed layer |
| Modelica.Units.SI.SpecificHeatCapacity | c_b (from RadiantSlabChar) | 840 | Thermal capacity of the concrete/screed material |
| Modelica.Units.SI.Density | rho_b (from RadiantSlabChar) | 2100 | Density of the concrete/screed layer |
| Integer | n1 (from RadiantSlabChar) | 3 | Number of discrete capacities in upper layer |
| Integer | n2 (from RadiantSlabChar) | 3 | Number of discrete capacities in lower layer |
| Integer | nParCir (from RadiantSlabChar) | 1 | number of circuit in parallel |
| Modelica.Units.SI.ThermalConductivity | lambda_i (from RadiantSlabChar) | 0.036 | Heat conductivity of the insulation |

| Modelica.Units.SI.CoefficientOfHeatTransfer | alp2 (from RadiantSlabChar) | if tabs then 0.3 else lambda_i/d_i | Convective heat transfer coefficient between the floor layer and the room below. In case of a floor heating system, this variable is set equal to the ratio of the heat conductivity and thickness of the insulation |
