An overview of how air conditioning works

For some reason most people understand how a furnace functions, it is only a matter of heating air and blowing it throughout the house using the duct system. The air is heated in a boiler or a furnace using one of a number of different fuels but how do air conditioning systems work? How can something make cool dry air?

An air conditioner is a machine made up of five basic components, these components work in harmony with each other and take heat from a home or commercial structure and put it outside. Air conditioning in Cincinnati is made up of refrigerant, the compressor, the condenser, and expansion valve and an evaporator coil.

There are a number of different types of air conditioning in Cincinnati; window units, split units and central air conditioning are by far the most common. Although they are different, they all use the same five basic components.

Refrigerant: The refrigerant changes state, it goes from a liquid to a gas as it collects the heat from inside the building and takes it outside. Refrigerants are special materials that have an extremely low boiling point which allows the medium to change from a liquid to a gas at low temperatures.

Compressor: If the refrigerant is the “blood” of air conditioning in Cincinnati then the compressor is the “heart”. The compressor pumps the refrigerant through the components in a never ending loop. The refrigerant goes into the compressor at low pressure and leaves it as a high pressure vapor.

Condenser: The hot refrigerant that leaves the compressor and enters the condenser. It is here where the vapor is cooled. Air blows over the fins of the condenser, as the refrigerant changes state from a hot gas to a hot liquid it moves to the expansion valve. The compressor and the condenser coil and fan are located outdoors.

Expansion valve: This is really what does the work. The hot liquid enters the valve and travels through a small orifice, it emerges as a cool, low pressure mist that goes into the evaporator coil.

Evaporator coil: The evaporator coil is located in the plenum of the furnace, the hot air in the home is blown across the coil, the cold coil cools the air which blows across it and delivers it back into your home.

With that you have fully functional air conditioning in Cincinnati.
