A/c, or cooling, is more complex than heating. Instead of utilizing energy to create heat, air conditioning system use energy to take heat away. The most typical a/c system utilizes a compressor cycle (similar to the one used by your refrigerator) to move heat from your home to the outdoors.

There is a compressor on the outside filled with an unique fluid called a refrigerant. This fluid can change backward and forward in between liquid and gas. As it alters, it absorbs or releases heat, so it is used to "bring" heat from one location to another, such as from the within of the fridge to the outside.

And the procedure gets a fair bit more complicated with all the controls and valves included. But its effect is amazing. An air conditioning unit takes heat from a cooler place and discards it in a warmer place, seemingly working versus the laws of physics. What drives the procedure, obviously, is electrical energy quite a great deal of it, in reality.

In each system, a large compressor system situated outside drives the process; an indoor coil filled with refrigerant cools air that is then distributed throughout your home through ducts. Heatpump resemble central air conditioners, other than that the cycle can be reversed and used for heating throughout the winter season.

In fact, the main air conditioner usually utilizes the heating system fan to distribute air to the ducts. Central air conditioning conditioners and air-source heat pumps running in the cooling mode have been ranked according to their seasonal energy performance ratio (SEER) given that 1992. SEER is the seasonal cooling output in Btu divided by the seasonal energy input in watt-hours for an "typical" U.S.

Prior to 1992, different metrics were used, however the performance of numerous older central air conditioning conditioners was equivalent to SEER ratings of only 6 or 7. The typical central air conditioning conditioner offered in 1988 had a SEER-equivalent of about 9; by 2002 it had actually increased to 11. 1.  Need More Info?  for central air conditioners and air source heatpump now requires a minimum SEER of 13 (because 2006), and to get approved for ENERGY STAR requires a SEER of 14.
