Experts,
I request your valuable comments on the case below,
Two numbers of 80 TR (W,S) chillers are installed for a commercial building of 100 TR cooling demand. Chillers are designed considering 20% diversity factor. There is a constant flow primary pump set with water flow rate 200 GPM...
Dear Experts,
I have the following data for heat load calc using excel sheet.
Outside DB = 38 Deg C
Outside WB = 30.8 Deg C
Outside RH = 60%
Inside Room conditions = 23.5 Deg C, 55% RH
Room Total sensible heat = 10000 BTU/HR
Room Total latent heat = 1800 BTU/HR
There is no mixing of return...
Experts,
Can someone list out the steps to find pressure relief valve set value in a closed loop chilled water system?
Thanks in Advance

Experts,
In a variable primary flow chilled water system (air cooled), total frictional loss is 6.5 bar as per calculation. Is this same as chilled water system working pressure, or different?
Thanks in advance

Hi experts,
HVAC related books say, in a primary-secondary chilled water system, the flow is controlled by the 2-way valve in the coil return side and the pressure in the supply pipe shoots up which is sensed by the dpt and dpt signals the secondary pump vfd to reduce pump speed.
If this is...
Hi experts,
In expansion tank sizing software the following inputs required.
1. Maximum design pressure
2. Operating pressure
How to calculate these parameters?
Thank You
