DESCRIPTION

A. This section specifies // self-contained, // split-systems, // rooftop, // room-type, // and // through-the-wall packaged terminal // air conditioners//and gas-fired furnaces//. B. Definitions:

1. Energy Efficiency Ratio (EER): The ratio of net cooling capacity is Btu/h to total rate of electricity input in watts under designated operating conditions (Btu hour/Watt).

2. Seasonal Energy Efficiency Ratio (EER): The ratio of the total cooling output of an air conditioner during its normal annual usage period for cooling in Btu/h divided by total electric energy input in watts during the same period (Btu hour/Watt).

3. Unitary: A Unitary Air Conditioner consists of one or more factorymade assemblies which normally include an evaporator or cooling coil, a compressor and condenser combination, and may include a heating function as well.

4. Where such equipment is provided in more than one assembly the separated assemblies are to be designed to be used together and the requirements of rating are based upon use of matched assemblies.
