Adrian,
The data in the example files is from a real machine. I suspect
the simplest thing to do would be to go to a manufacturer website
and get data for a machine that covers the temperature range you
need. The other alternative is that you can take the example data
file and plot it in a spreadsheet program, look at the shape of
the performance curves out near the limits of the temperature
range specified, make an educated guess as to how the curve
extrapolates, and then add data to the sample file.
kind regards,
David
Dear TRNSYS users,
does someone know where I can find performance data of air-water heat pumps? I want to simulate a heat pump with about 20 kW heating capacity and an inlet water temperature of 60-65°C. I'm going to use Type 941 which neglects the humidity of air.
I don't want to simulate a specific heat pump model so I would accept any data of a heat pump with similar characteristics, in order to have approximate results.
The problem with the sample data file is that the upper temperature limit for inlet water is 50°C and the maximum air temperature is 20°C. I need air temperature up to 35°C. Besides I don't know if the data in the sample data file are realistic or if they are only an example for the format of the data.
I would be very grateful if you can tell me where I can look for such data.
Regards,
Adrian Riebel
