This article describes designing heating systems with radiant ceiling panels.

Modules and program configuration

• InstalSystem 5 package with the following module:
  • Radiant heating&cooling systems with ceiling/wall panels

Inital state

1. Project scope tab - set the scope of project: Heating systems.
2. Catalogues tab – load product catalogues required for the project.
3. Thermal systems/Sources tab – verify the parameters: Default source use and supply temperature (θ_s,H).
4. Thermal systems/Distribution system/Virtual connections of radiant systems tab - select Allow system with no manifolds.
5. Thermal systems/Distribution system/Pipes and insulation - default types and data tab – specify default pipe and insulation type, verify other data.
6. Storeys management tab – verify and specify basic parameters:
   • Storey height
   • Default distance between ceiling and distribution pipe-runs to radiant panel system (ΔH_{pipe-run,pan.})
   • Default distance between ceiling and radiant panels by entering the value in field (Thickness of false ceiling)
     
7. Radiant systems/Panels tab – specify default types and sizes of radiant panels and adjust minimum (Δθ min) and maximum (Δθ max) permissible drop of temperature of the medium. The program will determine an optimum value within that interval for each radiant panel in order to attain the required output.

Edit installation - radiant ceiling panels

Insert radiant panels and edit graphically

Verify the arrangement of radiant panels, i.e. distances between panels, distances to top slab and external walls, with manufacturer's guidelines.

1. Select Rad.-ceilings.
2. Using the AUTO mode settings specify the desired distance between radiant panel and external wall.
   

   

   1. Radiant ceiling panel

   
   
3. Insert the radiant panel using the icon Ceiling panel in group Radiant
4. Adjust the length of the radiant panel to the dimensions of the room by dragging terminal points of the panel and expanding it.
   The length of the panel in the drawing does not have to correspond to the real length of a single panel. Based on the required length, the program will assemble a set of base panels and connection headers connected in series with its total length coresponding to the required length.
5. Insert subsequent radiant panels by clicking again the Ceiling panel icon or by copying panels already inserted. When necessary modify the settings of the AUTO mode.
   

Initial calculations - diagnostics of the heat demand coverage in room

1. Run radiant heating calculations by clicking the icon in the Calculations group.
2. Verify the heat demand coverage in room in:
   • the Diagnostics window by viewing the list of warnings
   • the Results window in the List of rooms - heating tabs
   • the hint bubble displayed upon positioning the mouse cursor within the panel area

Modify data to adjust the attained output to the required output

1. Adjust the following data and parameters:
   • supply temperature in the general data of the source (θ_s,H)
   • required drop of temperature of the medium in the radiant panel (Δθ_req,H).
     

     

     2. Correction of temperature drop of medium in radiant panel (Δθwym,H)

     
     
   • number/size of radiant panels
2. Recalculate the project – verify the effect of the changes made on the attained heating output.

Edycja instalacji - uzupełnienie rysunków o instalację rozprowadzenia czynnika roboczego

1. Po uzyskaniu zadowalających wyników pokrycia potrzeb cieplnych pomieszczeń wprowadzić pozostałe elementy instalacji (źródło, działki, armaturę) i połączyć z promiennikami.

Wykonanie kompletnych obliczeń wraz z równoważeniem instalacji i zestawieniem

1. Wykonać obliczenia dla zakresu ogrzewania płaszczyznowego za pomocą ikony znajdującej się w grupie Calculations.
2. Zweryfikować diagnostykę i wyniki obliczeń, w szczególności:
   • Wymagane parametry źródła - okno Results – zakładka Results Heating/General results heating
   • Zrównoważenie hydrauliczne instalacji – okno Results – zakładka Circuits
   • Zestawienie materiałów - okno Results – zakładka Bill of materials - heating / cooling

Weryfikacja wizualna poprawności przebiegu instalacji w widoku 3D

1. Otworzyć okno 3D view i zweryfikować przebieg instalacji, w razie konieczności zmodyfikować rzędne elementów i położenie punktów podłączeń. Po wprowadzonych korektach należy ponownie przeliczyć projekt.

   3. Widok 3D

   
   

Przygotowanie rysunków do wydruku/eksportu

1. Zweryfikować styl rysunkowy panelu w 2D i 3D i szczegółowość informacji prezentowanych w etykiecie. Konfiguracja dostępna jest w oknie General data.
2. Wstawić i skonfigurować etykiety innych elementów instalacji (źródła, działek, armatury).
