BSE UNIT 12 LESSON 1 Quiz on Air Conditioning (AC) in Buildings

What is one of the objectives learners should achieve by the end of the session on air conditioning (AC) in buildings?

• Calculate the energy consumption of AC systems

• List the reasons why AC is provided in buildings

• Design a new AC system

• Compare AC systems with traditional cooling methods

Which of the following is an objective for learners studying AC systems in buildings?

• Evaluate the cost-effectiveness of AC systems

• Draw the layout of a central plant AC system

• Analyze the environmental impact of AC systems

• Invent a new type of AC system

What should learners be able to describe regarding AC systems by the end of the session?

• The color coding of AC system components

• The operation of two types of AC systems

• The marketing strategies for AC systems

• The installation process of AC systems in high-rise buildings

By the end of the session, learners should be able to explain which aspects of AC systems?

• The historical development of AC systems

• The electrical circuits used in AC systems

• The advantages and disadvantages of various AC systems

• The warranty terms for different AC systems

What is the primary function of air conditioning (AC) in buildings?

• To provide lighting to the building

• To supply adequate oxygen, comfortable temperature, and remove CO2 and odours

• To supply internet connectivity

• To provide structural support to the building

What does air conditioning (AC) control in addition to heating and cooling a building?

• The color of the walls

• The humidity of the air

• The electrical systems

• The plumbing systems

What is the effect of the air being conditioned in central plant AC systems before being distributed?

• The effect varies significantly from room to room.

• The effect will be identical throughout the building.

• The air quality is reduced.

• The system only cools the air without conditioning it.

How can the effect of the conditioned air be changed in central plant AC systems?

• By increasing the speed of the supply fan.

• By opening the windows in each room.

• By reducing the off-coil temperature.

• By adjusting the return air fan speed.

What is the purpose of the reheat battery in central plant AC systems?

• To cool the supply air before it enters the room.

• To reheat the supply air before it enters the room.

• To filter the supply air before it enters the room.

• To humidify the supply air before it enters the room.

What is the purpose of the preheater battery in central plant components?

• To cool the air before it enters the room

• To heat fresh air to 70°C in the winter cycle to prevent filters from freezing

• To mix fresh air with recirculated air

• To create positive air pressure in the room
