Part 1-HVAC Manual Cooling Load Calculation with Practical Example, Design Ideas, Issues & Questions

Welcome Dudes!

In HVAC Manual Cooling Load Calculation Videos (Part-1 to 7), I provided the details of HVAC all important basic parameters explanation with all formulas. I included the basic psychrometric parameters like Dry Bulb, Wet Bulb, Relative Humidity, Humidity Ratio with detailed examples for clear and easy understanding. Also, i explained how to find out the building thermal condition or weather properties from ASHRAE climatic condition.

I covered how to select indoor design condition, thermal zoning concept which includes the selection of thermostat, VAV (Variable Air Volume), CAV (Constant Air Volume).

I also added the concept of Sensible & latent load with formulas. A detailed explanation with formulas given to find out the Room Internal Sensible Load, Room External Sensible Load, External to Internal Sensible Load due to un-treated air, Latent Load.

I also provided the details of how to find out the Fresh Air value for the room, concept of Fresh Air Handling Unit.

I also covered the U-Value, R-Value concepts and how to find out the U-Value of External Wall, Roof, Floor, Partition, Glass or Window with Carrier Handbook reference.

Sensible Heat Gain, Latent Heat gain, HVAC ducts leakage, FCU or DX Split units or other internal HVAC ducts concepts added to find out the sensible and latent safety factor.

At the end of the video, you will get to know how to find out the Ton of Refrigeration or KW of HVAC units along with the concept of How to find out the Air flow for HVAC units, How to find out the ON-COIL and OFF-COIL Temperature for HVAC units and how the HVAC cooling load software HAP is working and how to compare the results of HAP With manual cooling load calculation.

And finally, diversity factor concept to select the HVAC units also explained..
