2. Blower
The blower, also known as the air handler, is responsible for circulating the cool air throughout your home. It blows air over the evaporator coil to cool it down. The blower also pushes the conditioned air through the ductwork and out of the vents.
3. Condenser
The condenser is located outside your home. It releases the heat absorbed from your indoor air to the outside environment. The condenser unit contains the condenser coil, fan, and compressor. It is crucial for the heat transfer process.
B. How the AC System Works
To understand why your AC sounds like a jet engine, it’s essential to grasp how the AC system works. The AC system follows a refrigeration cycle, which involves the transfer of heat from inside your home to the outside environment. The process can be summarized as follows:
1. Refrigerant cycle
The refrigerant, a chemical compound with excellent heat transfer properties, circulates through the AC system. It transitions between liquid and gaseous states to absorb and release heat. As it moves through different components, such as the evaporator and condenser coils, it undergoes phase changes to cool and heat the air.
2. Air circulation process
The air circulation process begins with the blower drawing warm air from your home over the evaporator coil. The refrigerant inside the evaporator coil absorbs the heat from the air, cooling it down. The now-cooled air is then pushed back into your home through the ductwork and vents, providing a comfortable indoor environment.
