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.
