One of the greatest luxuries of modern-day living is central air conditioning. While it may not necessarily seem like a luxury, imagine living without it. At Air Temp, we help homeowners in Passaic, New Jersey get the most out of their AC systems by installing quality products backed by top-notch installation service. Our New Jersey certified technicians can install the right air conditioning system for your home. Below, we explain how air conditioning systems work.
Central Air Conditioning Components
To help you understand how your central AC system operates, it’s helpful to familiarize yourself with its parts. Every central AC system has several vital components including:
- Outdoor Unit. This unit includes the condenser, compressor, fan, and electrical components.
- Evaporator Coil. This coil is typically located on or in the indoor furnace or air-handling unit.
- Refrigeration Lines. Pipes that connect the indoor and outdoor equipment.
- Ducts. Air tunnels that circulate air throughout the home or building.
- Filter. Filters out airborne pollutants from the air circulating through the ducts.
- Refrigerant. The substance that circulates through the refrigeration lines.
- Thermostat. The device that allows you to control air temperature.
Not all central AC systems contain ducts, as there are ductless systems that operate without them. However, traditional central air conditioning systems employ these tubes to move air throughout the home. Regardless of the type of central AC your home has, these systems operate in the same general manner.
Removing Heat From Indoor Air
While it may seem that your air conditioner is creating cold air and forcing it into your home, that’s actually not the case. Your central AC system simply removes heat from the air inside your home. After the heat is removed, the cool air circulates back into your home. Here’s how it works:
- Warm air from inside your home passes through filters housed inside ducts. The filters remove airborne pollutants as air passes through them.
- When the air enters the return-air ducts, it travels to the air-handling unit where it moves across the evaporator coils.
- Inside the evaporator coil is a substance called refrigerant. Refrigerant enters the coil as a very cold liquid and is responsible for removing heat from the air.
- As the warm air proceeds across the evaporator coil, the refrigerant absorbs its heat and the temperature of the air decreases.
- When the temperature of the air falls, the moisture it holds begins to condense. This condensation runs into a drip pan where it drains away via drain lines.
- The cold air then returns back into the home via the evaporator fan.
The above steps detail how warm air is converted to cool air, but what happens to the refrigerant? If it absorbs heat from the incoming air, it can no longer remain a cool liquid. What happens when a liquid absorbs heat? It becomes a gas. That’s where the compressor comes in.
Compressing Warm Vapor
When the liquid refrigerant absorbs heat from the passing air, it changes state and becomes a vapor. This warm vapor travels into the compressor via the low-pressure side of the unit. The compressor compresses the vapor as it circulates through the refrigerant lines attached to it. This action causes the vapor to increase in temperature before it passes into the condenser.
Condensing Vapor Into Liquid
After the refrigerant compresses, it passes into the condenser coil. As it circulates through the coil, an interior fan generates air to cool the refrigerant. As it cools, it changes state back into a liquid. As the heat transfers away from the liquid, it blows out of the condenser into the outside air.
Repeating the Cycle
Now that the vaporized refrigerant has converted into a liquid, it must pass through a metering device that lowers its pressure. As the pressure decreases, the temperature of the refrigerant drops. After the temperature has dropped significantly, the liquid returns to the evaporator coil once again. Here, it will repeat the cycle as warm air from your home is pulled into the warm-air return vents.
