Medium to Large Unitary Air Conditioners
Copper can generate performance curves for IEER-rated unitary air conditioners. The performance curves are generated using the same approach as for chillers, which is described in the Chillers section. The performance curves generated by Copper follow the direct-expansion cooling coil model implemented in EnergyPlus. Additional documentation on the direct-expansion cooling coil model can be found in the EnergyPlus engineering manual.
