TRNAUS is an extension package for TRNSYS version15 for simulating thermosyphon solar water heaters, heat pump water heaters, stratified storage tanks with heat exchangers and a range of control modules.
The TRNAUS manual describes the modelling routines and the TRNSYS parameter, input and output lists.
Extensions include programming for
extended thermosyphon loop modelling for flat plate and evacuated tube solar collectors
over-temperature cut-off valve for thermosyphon loop
heat exchangers in thermosyphon loops
serpentine riser solar collectors in thermosiphon loops
reverse flow in thermosyphon systems
heat pipe coupling between a solar collector and a storage tank
evacuated tube collectors
bi-axial incidence angle modifier extensions
modelling specified energy load delivery
in-tank gas boosting for single tank solar/gas systems
load quality binning
Stratified tank model with integral heat pump condenser
Typical Meteorology Year data files of hourly solar radiation and climatic data for 22 cities in Australia.
