Heating and cooling installations
Radiant systems design
- Supply temperature optimization - proprietary method
- Thermal calculations for wet (pipe in screed) and dry systems (heating and cooling):
- EN 1264 with the update to EN 1264-2/A1:2012-06 taking into account laminar flow in the calculations
- DIN 4725-200 for increased screed thicknesses
- National / manufacturer requirements saved in the system catalog
- Thermal calculations of panel systems:
- EN 1264 with the update to EN 1264-2/A1:2012-06 (heating and cooling)
- EN 14037 (heating)
- EN 14240 (cooling)
- Hydraulic calculation of panel systems:
- Zehnder's proprietary method for Zehnder steel radiators
- standard formulas (Darcy and Colebrook formulas) for other panels
Pipeline network calculations
- Hydraulic calculations - Darcy and Colebrook equations
- Diameter sizing - R_max and v_max criteria
- Hydraulic balancing - proprietary method
- Heat loss in pipelines - according to professional literature
- Pipeline insulation sizing - EnEv (German) or WT2008 (Polish) recommendations, depending on the market-language version
Designing installations with flat stations
- dimensioning of the primary network supplying flat stations, taking into account non-simultaneous demand of the medium for domestic hot water preparation in a plate heat exchanger, according to the TU Dresden or DIN 1988-300 method (the second one requires the water system calculation module in the package configuration)
Balancing the installation with predefined control loops
- according to the manufacturer's guidelines
