Abstract

Abstract A method of determining thermal performance of a condenser and a condensing unit within a cooling system includes selecting the condenser and the condensing unit from a condensing unit database. A compressor is selected from a compressor database based on at least one of capacity, electrical characteristics and refrigerant flowing through the cooling system. Simulation points for the cooling system are determined and condensing unit characteristics and compressor characteristics are processed based on user-specified simulation points to provide thermal performance data for the condenser or condensing unit.
