Understanding Your Air Conditioner
ENERGY-EFFICIENT AIR CONDITIONING
Are you considering buying a new air conditioner? Or, are you dissatisfied with the operation of your current air conditioner? Are you unsure whether to fix or replace it? Are you concerned about high summer utility bills? If you answered yes to any of these questions, this publication can help. With it, you can learn about various types of air conditioning systems and how to maintain your air conditioner, hire professional air conditioning services, select a new air conditioner, and ensure that your new air conditioner is properly installed. Proper sizing, selection, installation, maintenance, and correct use are keys to cost-effective operation and lower overall costs.
A TECHNICAL EXPLANATION OF HOW A SYSTEM WORKS
Air conditioners employ the same operating principles and basic components as your home refrigerator. An air conditioner cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.
A pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils. The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling the home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid giving up its heat to the air flowing over the condenser's metal tubing and fins.
CENTRAL AIR CONDITIONERS—SEER
Before 1979, the SEERs of central air conditioners ranged from 4.5 to 8.0. Replacing old central air conditioner with a SEER of 6 to 8 with a new unit having a SEER of 13 will cut your air conditioning costs more than in half. But you do not need to settle for the minimum standard—there is a wide selection of units with SEERs of 18.
