BSE PPT 5 Commercial/Industrial Quiz

What is a characteristic of industrial/commercial heating systems compared to domestic ones?

• They are less efficient.

• They require less maintenance.

• They require greater capacity.

• They are smaller in size.

What type of system is shown in the diagram?

• Two-pipe parallel return system: direct return

• Single-pipe system

• Three-pipe system

• Four-pipe system

How many loads are shown in the diagram?

• One

• Two

• Three

• Four

Where is the heat source located in the system?

• Cooling tower

• Machine room

• Outdoor-air processing unit

• Ventilation duct

What does the increased pipework in a two-pipe reverse return system lead to?

• Decreased pump duty

• Increased pump duty

• No change in pump duty

• Reduced efficiency

In the context of heating systems, what does the term 'low loss header' refer to?

• A type of boiler

• A component that maintains water velocity

• A heat emitter

• A water pump

What is the role of low loss headers in maintaining water velocity?

• They slow down the water

• They maintain water velocity

• They stop water flow

• They increase water pressure

What is the effect of a low loss header on water flow resistance?

• It increases resistance

• It eliminates resistance

• It reduces resistance

• It has no effect on resistance

In the diagram, what does the secondary return do?

• It supplies water to the heat source

• It returns water from the loads

• It filters impurities

• It increases water pressure

What is the main advantage of using a low loss header system?

• Increased energy consumption

• Simplified system balancing

• Higher installation costs

• Reduced water flow
