HVAC Quiz介紹：
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 Qui z:
* 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:
Q.

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.
Q.
Anover-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 .

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.
Q.
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 -2The 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. HVAC代表暖氣，通風和空調。暖通空調系統使舒適的環境條件給你。沒有人能否認我們lives.it空調的重要性使得有可能住在任何氣候條件下。
在技術方面，提供熱量和新鮮空氣基本面的關鍵要素是系統供暖，通風和空調。
這個程序將涵蓋空調的所有主要領域，從基礎知識到前進。維護，運行和設計在未來的版本。
暖通空調測驗的一些主要特點：
*有各種級別，從易到難
*問題會反復出現在會議上，直到你得到正確的答案。
*每個級別有不同的目標分數，降低水平降低的目標。
*有三次機會錯過了正確的答案來實現自己的目標分數。
*如果你不能失去三次機會後實現你的目標你的分數變為零。
*你可以不斷嘗試，直到你實現你的目標，達到一個新的水平。
有一些問題如下：
