HVAC Trivia Quiz On Air Conditioning

1. HFC STANDS FOR

HYDRO FLUORO CARBONS

Hydro fosforus chlorine

Hygenic fluoro cacium

The correct answer is HYDRO FLUORO CARBONS. HFC stands for Hydro Fluoro Carbons, which are organic compounds composed of hydrogen, fluorine, and carbon atoms. HFCs are commonly used as refrigerants, propellants, and solvents. They are considered to be a more environmentally friendly alternative to chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) as they have lower ozone depletion potential.

2. Why vav is used

To control the volume of air

To mentain the temperetur

To increasa the velocity of air

The correct answer is to control the volume of air. A Variable Air Volume (VAV) system is used to regulate the amount of air flowing into a space based on the desired temperature and occupancy needs. By adjusting the volume of air supplied, the system can maintain a comfortable environment while also optimizing energy efficiency. This allows for better control over the air distribution and ensures that the right amount of conditioned air is delivered to each zone or room.

3. Cav stands for

Cubic air variation

Core air vent

Constant air volume

The acronym "cav" stands for constant air volume. This term is commonly used in HVAC systems to refer to a type of air conditioning system that maintains a consistent airflow rate regardless of changes in the cooling or heating load. This means that the system delivers a constant volume of air to the space being conditioned, ensuring a consistent level of comfort.

4. What should be standard tempereture diffrence between inlet to outlet

10 degree farenheit

15 degree farenheit

20 degree farenheit

The standard temperature difference between the inlet and outlet should be 10 degrees Fahrenheit. This means that the temperature of the fluid or substance entering the system should be 10 degrees lower than the temperature of the fluid or substance exiting the system. This temperature difference is important for efficient heat transfer and maintaining the desired temperature within the system.

This means that the temperature of the fluid or substance entering the system should be 10 degrees lower than the temperature of the fluid or substance exiting the system. This temperature difference is important for efficient heat transfer and maintaining the desired temperature within the system.

5. Hvac stands for

The acronym HVAC stands for heating, ventilating, and air conditioning. This term is commonly used to refer to the systems and technology used in controlling the temperature, humidity, and air quality in indoor spaces. These systems are essential for maintaining a comfortable and healthy environment in buildings, homes, and other enclosed spaces. The heating component ensures warmth during colder months, the ventilating component ensures proper air circulation, and the air conditioning component helps in cooling the air during hot weather.
