Ventilation Rates

Ventilation rates refer to the amount of air exchanged between indoors and outdoors within a given time period. Here are some key aspects of ventilation rates:

1. Air Changes per Hour (ACH):

Measures ventilation rate as the number of air changes per hour.

2. CFM (Cubic Feet per Minute):

Measures airflow rate in cubic feet per minute.

3. Liters per Second (L/s):

Measures airflow rate in liters per second.

4. Ventilation Rate per Person:

Calculates ventilation rate based on occupancy.

5. Ventilation Rate per Unit Area:

Calculates ventilation rate based on floor area.

6. Minimum Ventilation Rates:

Specifies minimum required ventilation rates for various spaces.

7. Recommended Ventilation Rates:

Suggests optimal ventilation rates for comfort, health, and performance.

8. Maximum Ventilation Rates:

Ensures ventilation rates do not exceed recommended levels.

9. Variable Ventilation Rates:

Adjusts ventilation rates based on occupancy, activity, or pollutant levels.

10. Demand-Controlled Ventilation (DCV) Rates:

Adjusts ventilation rates based on real-time conditions.

11. Zone Ventilation Rates:

Specifies ventilation rates for specific zones or areas.

12. Occupancy-Based Ventilation Rates:

Adjusts ventilation rates based on occupancy schedules.

Proper ventilation rates maintain indoor air quality, comfort, and energy efficiency.

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...
