Measure the square feet of the room’s floor and multiply that by 20. The AC unit you choose must have roughly 20 BTUs of cooling per square foot of room space. It includes the appliance’s efficiency when the compressor is energized and running and when it’s not running, in standby mode. The CEER number expresses the ratio of cooling capacity, measured in British Thermal Units, relative to how much electricity the appliance uses to cool the space. CEER is the efficiency rating that applies to window air conditioners. Look for an AC unit with the highest Combined Energy-Efficiency Ratio possible. However, the appliance’s cooling capacity, features, and controls differ. The cooling process is identical among various window air conditioners. Alternatively, the fan on the back picks it up and throws it against the hot coil, where it’s converted back to moisture vapor and discharged outside with the hot air. This water drips down to the back of the appliance and runs out through a drain. The moisture vapor in the indoor air condenses on the coil’s cold surface. In the summer, there’s a lot of moisture vapor suspended in the air, and in order for you to feel more comfortable, the air conditioner has to remove it. In exchange, you get cool and dry air pumped inside.Įqually important in the cooling process is dehumidification. Another motor-driven fan blows outdoor air over this hot, liquid-filled coil and discharges the heat to the outdoors. The appliance’s compressor draws the heated gas to a coil on the back of the appliance, converting the gas into a liquid. The heat energy in the room passes through the metal coil into the cold refrigerant inside. Window air conditioners use motor-driven fans to pull hot, moist indoor air over a metal tube coil with cold refrigerant gas inside.
