HVAC AC Basics

What does HVAC stand for?

• Household Ventilation and Air Conditioning

• Heating, Ventilation, and Air Conditioning

• Heating, Ventilation, and Cooling

• High Voltage Air Control

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.

• It involves the processes of compression, condensation, expansion, and evaporation.

• The refrigeration cycle in an AC system doesn't involve any specific processes.

What are the common types of refrigerants used in AC systems?

• Freon-12, Freon-22, and Freon-134

• R-410A, R-22, and R-134a

• Propane, Butane, and Ethanol

• Nitrogen, Oxygen, and Carbon Dioxide

What is the importance of proper maintenance for an AC system?

• To increase the risk of breakdowns

• To make the AC system less efficient

• To ensure efficiency, longevity, and prevent costly repairs.

• To save money on energy bills

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

• Increasing the use of AC systems to cool the environment

• Energy-efficient models, regular maintenance, and proper disposal of old units

• Throwing old AC units in regular trash
