How Air Conditioning Units Work
Understanding how air conditioning units operate is essential for homeowners, especially when considering the importance of proper sizing. At its core, an air conditioning system works by removing heat and humidity from the indoor air, thereby cooling the space. This process involves several key components that work together seamlessly.Key Components of an Air Conditioning Unit
- Compressor: Often referred to as the heart of the AC unit, the compressor pumps refrigerant through the system. It compresses the refrigerant gas, raising its temperature and pressure before sending it to the condenser.
- Condenser Coil: Located outside the home, the condenser coil releases heat absorbed from inside.
As the hot refrigerant gas passes through this coil, it cools down and condenses into a liquid.
- Expansion Valve: This component regulates the flow of refrigerant into the evaporator coil. It allows high-pressure liquid refrigerant to expand and turn into a low-pressure gas, which is crucial for the cooling process.
- Evaporator Coil: Situated inside your home, this coil absorbs heat from indoor air. As warm air passes over the evaporator coil, the refrigerant inside absorbs heat and evaporates into a gas, effectively cooling the air.
- Blower Fan: The blower fan circulates cool air throughout your home by pushing it through ducts or directly into rooms, ensuring even distribution of temperature.
The Cooling Process Explained
The cooling cycle begins when warm air from your home is drawn into the AC unit by the blower fan. This air passes over the evaporator coil, where it is cooled as heat is absorbed by the refrigerant.
The now-cool air is then circulated back into your living space.Simultaneously, the refrigerant, now in gaseous form after absorbing heat, travels back to the compressor. Here, it is compressed and sent to the condenser coil outside. In this stage, heat is released into the outdoor environment as the refrigerant condenses back into a liquid state.This cycle repeats continuously until your home reaches the desired temperature set on your thermostat. Understanding these components and processes highlights why having a properly sized AC unit is vital; an incorrectly sized unit can disrupt this cycle, leading to inefficiencies and discomfort.
Consequences of Improperly Sized AC Units
