Re: [TRNSYS-users] PV powered air conditioning
Michael,
I think you would need to rewrite the heat pump model so that it takes
the available power as an input and returns the machine's available
capacity as an output. We had to do this with a pump model a few years
ago because we had the same situation; a pump that was directly
connected to a PV.
My impression is that variable speed compressor heat pumps are fairly
new to the market and that you find the performance files from a
manufacturer who makes one and see if you can turn their catalog data
around so that power and entering conditions are the independent (input)
variables and capacity is the dependent (output) variable. Normally,
heat pump performance files have the entering conditions as inputs and
both the power and capacity as outputs.
Kind regards,
David

Dear TRNSYS-users,
I am trying to model a PV powered heat pump for cooling purpose
(variable speed => no battery required, power from PV is used
directly). I would like to try Type 94a (PV), 48a (inverter) and 665-8
(heat pump) but I can't find a "power input" for the heat pump, there
is only the required power as an output. In case, is there
alternatives for the 665-8?
Thank you very much for your suggestions!
Kind regards
Michael Mischkot
