FIVE IMPORTANT FACTS ABOUT COMMERCIAL BUILDING COOLING SYSTEMS:-

1. The purpose of the cooling system in a commercial building is to:
+ remove heat
+ maintain a comfortable indoor temp
+ maintain humidity level for occupants
👉🏼 This is essential for creating a productive and healthy work environment.

2. Commercial HVAC systems often use a “split system” design for more flexibility in zoning and temperature control compared to a single packaged unit.
📦 Packaged unit: everything is one box
🖖 Split system: with one or more indoor “AHUs”, air handling units, connected to an outdoor condensing unit.

3. Variable Air Volume VAV systems are commonly used in commercial buildings.
💨 They can vary the airflow to different zones based on cooling/heating demand.
💴 This improves energy efficiency compared to constant air volume systems.

4. Variable Refrigerant Flow VRF or Variable Refrigerant Volume VRV systems are becoming more popular in commercial applications.
❄️ They allow for individual temperature control of different zones
They can recover heat from one area to heat another.

5. Commercial cooling systems often run year-round, even when outdoor temperatures are cool, to maintain consistent indoor conditions and air circulation.
⚡️ This can be energy-intensive
👨‍💻 This means proper HVAC system design and controls are crucial for efficiency!
