Requirements w.r.t Properties Ontology #3

Dear all!

here some notes on requirements for properties ontology.

The following requirement is derived from a comment by Richard Pinka (CTU Prag):

Varying Properties

Problem: The COP or other performance measures of a piece HVAC equipment are dependend on the operating conditions. For example the efficiency of a chiller changes dependend on how close or how far away it is from its optimal performance point. Hence, in product data of a chiller there might not be one single value for the COP but a mathematical function or tabular data defining dependent on a input the calculation of the COP.

Requirements: A property ontology must be able to describe tabular data or mathematical function to express properties which have a range of values.

Examples are depicted for chillers in Fig. 8 of Yu and Chan also DOI
