What is the purpose of an air conditioning system in HVAC?
To provide lighting and ventilation
To regulate the sound levels in the building
To control temperature, humidity, and air quality
To control the flow of water in the building
What are the main components of an AC system?
Compressor, condenser, expansion valve, and evaporator
Fan, filter, thermostat, and ductwork
Blower, accumulator, receiver-drier, and metering device
Heater, radiator, exhaust pipe, and fuel pump
What is the role of a compressor in an AC system?
It filters the air before circulating
It controls the temperature of the refrigerant
It generates electricity for the system
It pressurizes and circulates the refrigerant
What is the difference between a split AC and a window AC?
Split AC is more expensive than window AC
Window AC is more energy efficient than split AC
Split AC is easier to install than window AC
Split AC has two separate units, while window AC is a single unit
How does the refrigeration cycle work in an AC system?
It involves the processes of heating, cooling, condensation, and evaporation.
It only involves the process of evaporation.

What are the energy-saving tips for using an AC system?
Set the thermostat to a higher temperature, use ceiling fans, keep the filters clean, and seal any air leaks in the room.
Keep the thermostat at the lowest temperature
Keep the filters dirty to save energy
Use space heaters in conjunction with the AC
What are the environmental impacts of AC systems and how can they be mitigated?
Using AC systems has no impact on the environment
