Understanding the a/c efficiency
Air-Source Heat Pump (ASHP):
An air-source unitary heat pump model consists of one or more factory-made assemblies which normally include
an indoor conditioning coil(s), compressor(s), and outdoor coil(s), including means to provide a heating function.
ASHPs shall provide the function of air heating with controlled temperature, and may include the functions of
air-cooling, air-circulation, air-cleaning, dehumidifying or humidifying.
Central Air Conditioner:
A central air conditioner model consists of one or more factory-made assemblies which normally include an
evaporator or cooling coil(s), compressor(s), and condenser(s). Central air conditioners provide the function of
air-cooling, and may include the functions of air-circulation, air-cleaning, dehumidifying or humidifying.
Heating Seasonal Performance Factor (HSPF):
This is a measure of a heat pump's energy efficiency over one heating season. It represents the total heating
output of a heat pump (including supplementary electric heat) during the normal heating season (in Btu) as
compared to the total electricity consumed (in watt-hours) during the same period. HSPF is based on tests
performed in accordance with AHRI 210/240 (formerly ARI Standard 210/240)1.
Seasonal Energy Efficiency Ratio (SEER):
This is a measure of equipment energy efficiency over the cooling season. It represents the total cooling of a
central air conditioner or heat pump (in Btu) during the normal cooling season as compared to the total electric
energy input (in watt-hours) consumed during the same period. SEER is based on tests performed in accordance
with AHRI 210/240 (formerly ARI Standard 210/240)1.
Energy Efficiency Ratio (EER):
This is a measure of the instantaneous energy efficiency of cooling equipment. EER is the steady-state rate of
heat energy removal (e.g., cooling capacity) by the equipment in Btuh divided by the steady-state rate of energy
input to the equipment in watts. This ratio is expressed in Btuh per watt (Btuh/watt). EER is based on tests
performed in accordance with AHRI 210/240 (formerly ARI Standard 210/240)
