Q1: Define Ventilation.
Ans:Ventilation is the process of supplying fresh air to a space and removing stale air to maintain air quality.
Q2: Write the importance of Ventilation.
Ans:Ventilation ensures proper airflow, removes harmful gases, and helps maintain comfort and health.
Q3: Which factors affect ventilation?
Ans:
Factors that affect ventilation include:- ➔ Temperature
- ➔ Humidity
- ➔ Wind direction
- ➔ Type of ventilation system used
Q4: What is Cross-ventilation?
Ans:Cross-ventilation is a method of airflow where fresh air enters through one side and exits through the other, cooling and refreshing a space.
Q5: Define opening.
Ans:An opening is a gap or space (like a window or door) used to allow air to enter or exit a room for ventilation.
Q6: What is the ventilation process?
Ans:Ventilation involves the movement of air to bring in fresh air and remove pollutants or hot air from a space.
Q7: What are the types of ventilation?
Ans:
The different types of ventilation are:- ➔ Natural ventilation
- ➔ Mechanical ventilation
- ➔ Mixed-mode ventilation
Q8: Define Natural Ventilation.
Ans:Natural ventilation relies on air movement from natural forces like wind and temperature differences to circulate air.
Q9: Define Mechanical Ventilation.
Ans:Mechanical ventilation uses fans or mechanical systems to move air in and out of a building.
Q10: Define Mix mode Ventilation.
Ans:Mixed-mode ventilation combines both natural and mechanical methods to improve air quality and comfort.
Q11: What are the important design considerations for ventilation?
Ans:
Important design considerations for ventilation include:- ➔ Airflow patterns
- ➔ Air distribution
- ➔ Humidity control
- ➔ Temperature
- ➔ Building layout
Q12: How does the direction of wind affect ventilation?
Ans:Wind direction can enhance or reduce airflow, affecting how efficiently air enters and exits a space.
Q13: What is the purity of wind?
Ans:The purity of wind refers to its cleanliness, which affects air quality. Purified air is free of pollutants.
Q14: Define Humidity.
Ans:Humidity is the amount of water vapor in the air, which can impact comfort and ventilation efficiency.
Q15: How does humidity affect ventilation?
Ans:High humidity can reduce air quality and comfort, while low humidity can dry out airways and materials.
Q16: Name the types of Natural ventilation.
Ans:
The types of natural ventilation are:- ➔ Window ventilation
- ➔ Stack ventilation
- ➔ Cross-ventilation
Q17: Name the methods of Mechanical ventilation.
Ans:
The methods of mechanical ventilation are:- ➔ Exhaust fans
- ➔ Air handling units
- ➔ Ducted systems
Q18: Explain the Central Plant System.
Ans:A central plant system provides heating, cooling, and ventilation from a single location to multiple parts of a building.
Q19: How does chimney help in ventilation?
Ans:Chimneys help ventilate by allowing smoke, heat, and gases to escape, creating a natural draft for air circulation.
Q20: What is wind driven ventilation?
Ans:Wind-driven ventilation uses natural wind to force air through a space, improving air exchange.
Q21: Define Roshan Daan and its effects on ventilation.
Ans:Roshan Daan is a traditional ventilation system that allows natural light and air to enter a building through small openings, improving air quality.
Q22: Define Ventilators.
Ans:Ventilators are devices used to circulate or supply air into a room or building, improving ventilation.
Q23: What are some design considerations for openings in ventilation?
Ans:
Some of the considerations are:- ➔ Size
- ➔ Placement
- ➔ Type (window, vent, etc.)
- ➔ Orientation to optimize airflow and comfort
Q24: Define Infiltration.
Ans:Infiltration is the uncontrolled movement of outdoor air into a building, typically through cracks or gaps in the structure.
Q25: What are some effects of ventilation?
Ans:
Ventilation has the following effects:- ➔ Improves air quality
- ➔ Reduces humidity
- ➔ Prevents mold
- ➔ Ensures comfort
