4TES-9Y 20KW With Inverter

The document provides output data from BITZER software for a 4TES-9Y semi-hermetic reciprocating compressor with an inverter operating at 20kW. It includes a project survey selecting the 4TES-9Y compressor and tables with input values for refrigerant R134a at specified temperatures. The results section lists technical specifications for the compressor like cooling capacity, power input, current draw, and coefficient of performance (COP) across a frequency range from 25-70Hz.
