HFC STANDS FOR
- A.
HYDRO FLUORO CARBONS
- B.
Hydro fosforus chlorine
- C.
Hygenic fluoro cacium
Correct Answer
A. HYDRO FLUORO CARBONSExplanation
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.Rate this question:

Why vav is used
- A.
To control the volume of air
- B.
To mentain the temperetur
- C.
To increasa the velocity of air
Correct Answer
A. To control the volume of airExplanation
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.Rate this question:

What should be standard tempereture diffrence between inlet to outlet
- A.
10 degree farenheit
- B.
15 degree farenheit
- C.
20 degree farenheit
Correct Answer
A. 10 degree farenheitExplanation
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.Rate this question:

Cav stands for
- A.
Cubic air variation
- B.
Core air vent
- C.
Constant air volume
Correct Answer
C. Constant air volumeExplanation
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.Rate this question:

Hvac stands for
Correct Answer
heating ventillating air conditioningExplanation
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.Rate this question:
