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`_.
