– TRNSYS Decks

Deck layout
 All include files shall be at the top of the deck immediately after the SIMULATION statement and the timestep shall be 0.02 h or less
 The chosen time step shall be an exact divisor of the load draw off period.
 The TOLERANCE statement shall be 0.005, 0.005 or less for relative tolerances.
 Each load draw-off event shall be applied over a period of 0.1 h for small SWHs and ASHPs and 1 h for large SWHs.
 Use the template deck structure in the version of the document titled CER template decks published by the Clean Energy Regulator, unless the Clean Energy Regulator approves in writing. Except for the product parameters, the template decks shall be used without modification unless the product has features not covered by the example decks.  There are different template decks for small SWHs, ASHPs and large SWHs.
Note:  The document 'CER template decks' could in December 2016 be viewed on the Clean Energy Regulator's website (http://www.cleanenergyregulator.gov.au/RET/Pages/Forms and resources/Forms-and-resources-for-manufacturers.aspx).
 The include files provided by the Clean Energy Regulator shall not be modified.
 All constants shall be towards the top of the deck.
 The output, list and other output file names shall be the same as the deck name except for the file type.
 The output printers in the example decks shall not be modified. Additional printers may be used if required.
Simulation display

     Simulation output: A TYPE 25 printer unit shall be included in the deck.  This shall output the following results: the zone, load size, percent energy savings, STC rating and annual energy delivered below 45°C.

     Energy balance: A monthly energy balance in a TYPE 28 output unit shall be included in the deck.  This shall include a full system energy balance i.e. collector input + boosting + pump input – load – pipe losses – tank losses – energy dumped.

     Runtime graph: A runtime graph (TYPE65) shall be included in each deck showing at least:

         o Hot water delivery temperature

         o Solar collector flow rate

         o Solar collector inlet temperature

         o Solar collector outlet temperature

         o Load

         o Similar variables shall be plotted for heat pump water heaters.

Solar collector area
 The area specified for the solar collector (absorber, aperture or gross) shall be the same as the area used for the specification of the solar collector efficiency coefficients.
Controller default settings

     If the maximum tank temperature setting of the pump controller used for no-load system operation test (clause 7.4.3.2 in AS/NZS 2712:2007) is not specified in the AS/NZS 2712:2007 test report, then a maximum value of 65°C shall be used (Tmax = 65oC and Tmax_reset
