The same number and capacity of pumps are being installed in both systems. When the pumps are headered then any pump can be used with any chiller. If the primary pumps are dedicated to each chiller then if 1 pump is down and a chiller not associated with this pump is also down the 2 chillers...
Does the Block Load give the required plant size? ASHRAE "Load Calculation Manual" applies only to room loads while ASHRAE Standard 183 is concerned mainly with the zone load. Is there a progression from the room load, to the zone load, to the block load for a floor and to the sizing of the AC...
What are the guidelines for selecting a particular type of chiller? What is the safe/optimum operating range in terms of tons of cooling for:
1. Chillers with scroll compressors (air cooled)
2. Chillers with screw compressors (air cooled)
3. Centrifugal chillers (water cooled)
Thank you.
In a communication with Prof. Spitler, author of ASHRAE "load Calculation Manual" he states that this manual addresses the room loads only.
ASHRAE Standard 183 (Calculating Peak Cooling and Heating Loads) states that it is intended to address the zone load and not the system load although both...

In installing a number (8) of air cooled chillers what are the advantages and disadvantages of having a dedicated primary pump for each chiller versus headering the primary pumps so that any primary chilled water pump can serve any chiller? What is the recommended option and why? Are there any...
