The return and outside air flow rates are a function of your system design and not the heat pump. A single-speed heat pump will always supply the same amount of air flow. The air entering the heat pump, before it is conditioned, is some combination of return air from the conditioned space and outside air. Your system design and control system will determine the fraction of the flow that is return and the fraction that is outside air.
The sample data files are just that - samples of the format for the data file. The actual number of dependent values that you need to have in your data file is based on the number of independent values that your are proving data for. Then the parameters for your component will need to match the number of independent values in your file. You must follow the format of the sample data file, but not the exact number of data points.
