There aren't any heat pump models in the current standard library.
The TESS HVAC Library has a number of different models available but
they all use the same basic computation methodology and read
performance from an external data file. Which heat pump model you
use depends on which heat pump technology you have (single stage
air-to-air, multi stage water (source) to air, variable speed air
(source) to water, etc.). If you can be more specific about what
kind of heat pump you want to use, I can suggest a specific Type for
you.<br>
<br>
You will find one difference in heat pump components in that some
are "normalized" and some are not. The non-normalized components
require that the machine's capacity and COP be entered into the
external performance data files for a number of different operating
conditions. The normalized versions take the machine's rated
capacity and COP as parameters while the external performance files
contain ratios of capacity at a particular operating condition to
the rated capacity (and ratios of COP at the operating condition to
the rated COP). <br>

<div>Hey TrnSys-community,<br>
</div>
<div><br>
</div>
<div>which types would you recommend (Standard, Standard TESS
and Non-Standard TESS) to use for simulating differnt heat
pumps. <br>
</div>
<div>Thank you very much for your help.<br>
