A Look at How Your Air Conditioning Works

By: Boyd Bros. HVAC

An air conditioner works a lot like a refrigerator does. Rather than simply cooling the insulated small space of a fridge, the air conditioner cools one room, your home, or even whole businesses.

There are chemicals used by air conditioners, and these chemicals convert easily from gas then to liquid before switching back again. The chemical’s used for transferring heat from air inside a building to the air outside.

There are three parts in the machine. These parts are the compressor, the evaporator, and the condenser. The condenser and compressor usually are found on the exterior air part of an air conditioner, an evaporator’s found inside the building or house, and it’s sometimes part of the furnace. This is the section which heats the building.

The fluid comes to the compressor as a low-pressure, cool gas. The fluid is then squeezed by the compressor. The molecules of the fluids are then packed together closer. This makes the fluid have higher temperature and higher energy.

This working fluid will then leave your compressor as a high-pressure, hot gas and flow into your condenser. If you’ve looked into your air conditioner outside of the house, look for the section with metal fins around it. Those fins act like radiators in cars and help with the heat dissipating a lot faster.

When that working fluid’s leaving the condenser, the temperature is a lot cooler and it’s changed from a gas to liquid using high pressure. That liquid enters the air conditioner’s evaporator by way of a narrow, very tiny hole. When it comes out, the temperature of the liquid drops and then it evaporates back into gas form.

As its changing to gas and evaporating, it’s extracting the heat from the surrounding air. The air’s heat’s needed for separating the fluid’s molecules from liquid to gas form.

Its evaporator additionally has the metal fins so it can help with exchanging thermal energy and the air around it.

When the working fluid has left your evaporator, it’s a low pressure, cool gas. Then it returns to the air conditioner’s compressor to start back on its journey once again.

Connected to an air conditioner’s evaporator’s a fan which circulates air in the house to go across the fins of the evaporator. Cold air is heavier, so the room’s hot air goes up to the room’s top.

There’s a vent through which air is sucked into your air condition and then goes down into the ducts.  This hot air’s used for cooling the gas the evaporator contains. Once the heat’s removed from this air, it’s cool. Then it’s blown back into the building through various other ducts, most of the time at floor level.

This keeps on happening until the room is the temperature that you want it to be. The air conditioner’s thermostat is what senses that it’s the right temperature and turns off your air conditioner, just like it happens with a heater. When your room warms up again, the thermostat will turn your air conditioner back on until the temperature in the room reaches the right level.

Heat Pump

Just imagine for a minute that you took your air conditioner and then flipped it so that its hot coils were inside and its cold coils instead were on its outside. You’d then have a heater. Surprisingly enough, this heater works really well. Instead of burning fuel, it’s moving heawt.

Heat pumps are air conditioners which have valves which let them go in between heater and air conditioner. When its valve is turned a certain way, it works like the air conditioner. When it’s turned another way, it’s reversing the liquid’s flow in the pump and then acts as a heater.

A heat pump is often really efficient when they use their energy. One of the major problems with most of the heat pumps is the coils on their exterior will collect ice. Every so often, the pump has the melt the ice, so it’s turning itself back to the mode of air conditioner so that the coils are heated up. So that you avoid pumping air that is cold into your home when this happens, it also lights up things like burners so that cold air that’s being pumped out is heated. After the ice’s melted, it goes back to heating and the burners get turned off.

Here are some tips that you can use to make your air conditioner work as efficiently as possible:

Duct maintenance and repair – Your home’s ducts have to carry all of the cool air into your home and through it. If there’s any cracks or leaks in the ducts, you may find that you are losing your cooled air. This is really wasteful and it also can make your home less comfortable.

Check your air filter – An AC system has a filter inside it that’s there to ensure that any dust or dirt isn’t getting into the system. If your air filter becomes clogged, it’s going to restrict air flow through your system so that it works harder to get the air through. This is going to reduce your system’s efficiency and make your home less comfortable.

Get maintenance regularly – One of the best things that you can do to make sure that your air conditioning is efficient is to have regular maintenance on your system. A technician will check for issues and problems that you might have in your air conditioning and checks its efficiency. They are going to repair the problems and ensure that your system’s working and that its doing as well as it possibly can.

When the hot weather comes, you want to make sure that your AC is working. Now that you understand how your air conditioning works and what you can do to make sure it’s efficient, keep up with it.
