Plate Heat Exchanger, How it works - working principle hvac industrial engineering phx heat transfer

The video tutorial explains plate heat exchangers (PHS), their components, and how they function. It covers their use in building services and manufacturing, highlighting their efficiency and low maintenance. The video details the components like end plates, nuts, and gaskets, and explains the heat transfer process, emphasizing the counter flow configuration for optimal performance. A real-world example of a German heat exchanger is provided, showcasing its capacity and efficiency.

What is one of the main reasons plate heat exchangers are popular in building services?

• They are difficult to service.

• They are compact and efficient.

• They require high maintenance.

• They are very expensive.

What material are the end plates of a plate heat exchanger typically made from?

• Aluminum

• Copper

• Mild steel

• Plastic

What is the purpose of the gaskets in a plate heat exchanger?

• To increase the weight

• To make the plates heavier

• To ensure a tight fit and prevent leaks

• To reduce the heat transfer

Why is the first version of piping configuration more common in plate heat exchangers?

• It is more expensive.

• It requires more pipe work alterations.

• It is less efficient.

• It allows easy extension without altering pipe work.

In a plate heat exchanger, how do the fluids typically flow for maximum effectiveness?

• Random flow

• Perpendicular flow

• Counter flow

• Parallel flow

What happens to the cold fluid as it passes through a plate heat exchanger?

• It remains cold.

• It cools down further.

• It evaporates.

• It warms up.

What is the effect on the hot fluid as it passes through a plate heat exchanger?

• It heats up further.

• It remains hot.

• It cools down.

• It solidifies.
