Anton, In order to create a new data file you'll need to have manufacturer's data for the machine that you want to model. Manufacturer's data usually includes some information that shows how the machine's cooling capacity changes as a function of the inlet conditions. Often they give values of full-load capacity for a number of inlet water temperatures in a table. The fraction of rated capacity is obtained by dividing the capacity at a given set of inlet conditions by the capacity at the machine's rated inlet conditions. The same principal is true for the design energy input. In the case of Type107 the design energy input is the amount of energy that is extracted from the hot water stream at the machine's rated condition. kind regards, David On 5/10/2015 4:25 AM, Anton Åhlund
