HVAC has been my profession for many years, So I was planning to make an app on HVAC, result came in HVAC Quiz. It is available on google play and it is one of my favorite app in my album.
Here is the LINK
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 will cover all the major areas of Air Conditioning, from basic knowledge to advance. Maintenance, Operation and designing in coming versions.
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 will 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
