What is a Cooling System and How Does It Work?
A cooling system removes heat and moisture from indoor spaces to maintain a comfortable temperature. These systems rely on refrigeration cycles, which involve the compression and expansion of refrigerants to absorb and release heat effectively.
Key Components of a Cooling System
- Compressor: Acts as the heart of the system, circulating refrigerant.
- Condenser Coil: Releases heat absorbed from indoors to the outside.
- Evaporator Coil: Absorbs heat from the air inside your home.
- Fan and Blower: Circulate cool air into the living space.
- Thermostat: Regulates the system and maintains the desired temperature.
