Supermarket Ventilation System Basics

The video tutorial explains the roles and functionalities of different HVAC units, including rooftop units, air handling units, and fan coil units. Rooftop units are common in supermarkets and provide an all-in-one HVAC solution by filtering, heating, and cooling air. Air handling units, typically larger and housed indoors, perform similar functions but rely on external chillers or boilers. Fan coil units circulate air locally and assist in maintaining desired temperatures. The video concludes with a summary of these systems.

What is the primary reason rooftop units are commonly used in supermarkets?

• They are cheaper to install.

• They provide an all-in-one HVAC solution.

• They consume less energy.

• They are easier to maintain.

How do rooftop units typically manage used air?

• They filter it and release it outside.

• They push it out of the building.

• They recycle it back into the building.

• They store it for later use.

What is a key difference between Air Handling Units and Rooftop Units?

• AHUs are only used for cooling.

• AHUs do not filter air.

• AHUs are larger and typically housed indoors.

• AHUs are smaller and located outdoors.

What is the purpose of an exhaust AHU in a building?

• To increase the building's temperature.

• To maintain pressure and extract used air.

• To reduce noise levels.

• To provide additional cooling.

What is the main function of a fan coil unit?

• To filter water.

• To heat water for the building.

• To circulate air locally and adjust temperature.

• To provide lighting.
