The condenser in an air conditioning system is where the refrigerant releases its heat to the outside environment.
A thermostat is used to regulate temperature settings, ensuring comfort levels are maintained.
The compressor increases the pressure and temperature of the refrigerant, allowing it to move through the system.
The expansion valve reduces the refrigerant's pressure, preparing it to absorb heat in the evaporator.
In a split system, the evaporator is located in the indoor unit to absorb heat from the room.
R-22 is a refrigerant known for its potential to deplete the ozone layer, leading to its phase-out.
A reduced cooling performance often indicates a refrigerant leak, as the system cannot properly cool the air.
Air filters should be replaced every 1-3 months to ensure efficient operation and air quality.
The refrigerant transfers heat from inside a building to outside, allowing the indoor environment to cool down.
The dew point is the temperature at which air becomes fully saturated with water vapor, causing dew to form.
