About this app

HVAC Quiz is an educational app that tests users' knowledge of heating, ventilation, and air conditioning (HVAC) systems. It may include a variety of question formats, such as multiple choice, true/false, identifying the tool or part image, or fill-in-the-blank, and cover topics such as HVAC system design, installation, repair, and maintenance. The app may be suitable for HVAC technicians, students, or anyone with an interest in learning about HVAC systems. It may offer features such as progress tracking, performance analysis, and the ability to review and learn from past mistakes.

HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC systems give comfort environment condition to you. No one can deny the importance of HVAC in our lives.it makes possible to live in any climatic condition.

In terms of technology, the key elements that provide the fundamentals of heat and fresh air are the systems for heating, ventilation and air conditioning.

This app covers all the major areas of Air Conditioning, from basic knowledge to advance. Maintenance, Operation and designing.

Some key features of HVAC Quiz:
* There are various levels, from easy to difficult
* Question will be repeated in the session till you give the right answer.
* Each level have different target score, lower the level lower the target.
* There are three chances to miss the right answer to achieve your target score.
* If you could not achieved your target after losing three chances your score
become zero.
* You can keep on trying till you achieve your target and reach to the next level.

There are some Questions as below:

One BTU is the amount of heat required to raise the temperature of:

Option -1 one pound of water one-degree Fahrenheit
Option -2 one gallon of water one-degree Fahrenheit
Option -3 one pound of ice one-degree Fahrenheit.
Option -4 one gallon of water eight degrees Fahrenheit.

An over-sized heating and cooling system can cause the following?

Option -1 Operating cost and relative humidity in the structure will decrease significantly.
Option -2 Moisture damage to a furnace heat exchanger and inadequate humidity removal during cooling cycles.
Option -3 The structure will develop low humidity levels in the cooling season and high humidity in the winter.
Option -4 Equipment will last longer and require less energy to operate due to the shorter run time.

Water is considered a refrigerant. What is its name?

Option -1 R-401
Option -2 R-718
Option -3 R-170
Option -4 R-1270

The essential parameters to estimate cooling load from air side across an air handling

Option -1 Flow rate
Option -2 Dry bulb temperature
Option -3 RH% or wet bulb temperature
Option -4 All of the above

Q.Metering device:
Option -1 changes as high pressure vapor to high pressure liquid
Option -2 changes a low pressure vapor to a low pressure liquid
Option -3 changes a high pressure liquid to low pressure liquid
Option -4 changes low pressure vapor to high pressure vapor

Which of the following statement is wrong?

Option -1 The heat transfer in liquid and gases takes place according to convection.
Option -2 The amount of heat flow through a body is dependent upon the material of the body.
Option -3 The thermal conductivity of solid metals increases with rise in temperature.
Option -4 Logarithmic mean temperature difference is not equal to the arithmetic mean temperature difference.

Which of the following statement is correct?

Option -1 The human body can lose heat even if its temperature is less than the atmospheric temperature.
Option -2 The increase in air movement increases the evaporation from the human body.
Option -3 The warm air increases the rate of radiation of heat from the human body.
Option -4 both (1 and 2)

Note: If you have your own questions and answers, we can add in this quiz to the benefits of others.

Sorry guys, but current decreases if voltage decreases and resistance is constant,,, this question came up a few times and is pretty basic knowledge... doing people who are just learning this material a huge disservice... proof read your info.

Its a great refresher course. Within a few days i was already at level-10, Howerver, i knew some of the anwsers were incorrect, like has been stated by many.I wonder if hes really certifyed ? And for beginners learning this feild be careful of what youre listening to. Because as stated, you go out and work on someones unit with the wrong information it could cost you hugely 👋

Do not use to gain knowledge, as the creator certainly had very little. Says compressor changes high pressure liquid to high pressure gas... I don't know what compressors he's working on, but it won't be mine.
