Purpose of ventilation system in HVAC

The purpose of ventilation is to:

1. Remove stale air:

Exchange stale air for fresh air to improve indoor air quality.

2. Control humidity:

Regulate moisture levels to prevent mold growth and condensation.

3. Reduce odors:

Eliminate unpleasant smells and gases.

4. Remove pollutants:

Extract airborne contaminants, such as dust, pollen, and chemicals.

5. Heat recovery:

Recover heat energy from exhaust air and transfer it to fresh air.

6. Cooling:

Provide cooling through evaporation or convection.

7. Air circulation:

Circulate air to prevent stagnation and promote even temperatures.

8. Pressure control:

Regulate air pressure to prevent damage to buildings and improve comfort.

9. Indoor air quality (IAQ) improvement:

Maintain healthy indoor air quality by removing contaminants.

10. Compliance with regulations:

Meet local building codes, regulations, and standards for ventilation.

11. Energy efficiency:

Optimize energy consumption by recovering heat and reducing heating/cooling loads.

12. Occupant health and comfort:

Provide a healthy and comfortable indoor environment for occupants.

Proper ventilation is essential for maintaining a healthy, comfortable, and energy-efficient built environment.

VALVES USED IN A CHILLER SYSTEM AND THE TYPICAL VALVE PACKAGE

VALVES USED IN A CHILLER SYSTEM AND THE TYPICAL VALVE PACKAGE 1.Chilled Water Side Valves ⇒Isolation valve (manual/electric actuated). ⇒ Installed on CHW supply and return lines. ⇒ Used to isolate chiller for maintenance. 2. Balancing Valve (Manual or Automatic) ⇒ Ensures correct flow rate to/from chiller. ⇒ Helps maintain Delta T and proper flow distribution. ⇒ Located after evaporator outlet (return line). 3. Differential Pressure Bypass Valve (if 2-way valves in system) ⇒ Prevents excess pressure build-up when terminals shut. ⇒ Maintains flow through chiller. 4. Flow Switch ⇒ Senses chilled water flow across evaporator. ⇒ Safety interlock: trips chiller if flow is lost. ⇒ Usually paddle type or electronic. 5. Air Vent Valve (Manual or Automatic) ⇒ Removes air pockets. ⇒ Placed at high points of piping and chiller headers. 6. Drain Valve ⇒ For flushing, cleaning, and maintenance. ⇒ Located at low poin...
