Re: [TRNSYS-users] Type 668 Heat Pump Performance Issues
Sorry, I should have been more clear. I do have the sample catalog data cooling map in there, but I am wondering if the very different capacities are effecting the results.
Are the heating and cooling mode calculations 100% independent, or are both performance maps called in the calculation?

Hi Fred
I don't know if it works well without a cooling map, but if you need to use
the heating mode only, you can use the default cooling file in the
"SampleCatalogData" folder to fill in the gap.

TRNSYS Users,
I am using a type669 heat pump in heating mode only and I have entered a
performance map for the heating side.
If I am using type668 in a heating mode only way, do I need to input a
corresponding cooling map?
In other words, are both a heating and a cooling map required for proper
operation of a heat pump in heating only mode?
What I am seeing in my output is that the heat pump heats the load side, but
does not draw any heat from the source side.
Please advise,
Fred
