Taking time to understand certain terms related to air conditioning can help you a great deal when it comes to maintenance of the air conditioning unit. Knowing the terms will also help you save some money when the time for replacing the unit comes. One of the terms you need to understand is seasonal energy efficiency ratio (SEER). It is a measure of the air conditioning unit’s efficiency. If you buy an AC unit that is more efficient, it will be cheaper to operate. The most efficient AC systems usually have a SEER rating of about 16 and above. With such systems, you can save a lot of money every year.
Another air conditioning term that you need to understand is modulation. It refers to variation in speed of the air conditioning unit. This implies that the energy used to power such air conditioners is modulated, and as a result it allows you to have an even temperature in your house. Such air conditioners also help when it comes to controlling humidity, which is one of that factors that determine how hot you feel in your house. As a result of this, the modulated ACs could help you save a lot of money every year.
Another important air conditioning term that you need to understand is heat pump. It is a traditional air conditioner that utilizes a refrigerant cooling system. The coolant is usually located in the coils of the system and it cools down the air that is then forced into your house. The heat pump actually pulls air from inside the house and dumps it outside. But the advantage with it is that you can also use it to heat your home when it is too cold. It gathers warmth from outside and then funnels it to the inside of the house.
Another term you need to understand is compressor. This is the part of the air conditioning system that is usually responsible for most of the noise. It is usually located outside of the air conditioner (condensing unit). It is the one that raises the temperature as well as pressure of the refrigerant. Refrigerant refers to working fluid that usually transfers heat in the air conditioning system. Another air conditioning term you need to understand is geothermal heat pump. This is a type of heat pump that usually pulls or dumps heat to or from a body of water or the ground.
You also need to understand what a plenum is in an air conditioner. It is a box that is attached to both sides of the handlers of the air conditioner. Other ducts are usually attached to it. On the return side (the side of the duct system that pulls air from the house to the air handler to be reconditioned) of the air conditioner, there may be a filter between the air handler and the plenum. On the supply side (the side of ducts that pushes conditioned air back to the house) of the air conditioner, the evaporator coil and the blower may be in a separate house.
