HVAC - views about CFC refregerent Vs. eco friendly refrigerent
(OP)
Hi
We are planning the HVAC for our new office site 80KSF. I would like your viewss on
Reciprocating Vs. Screw
Has anyone carried out any analysis between Recip and Screw to check the energy savings
What is your views about CFC refregerent Vs. eco friendly refrigerent.
What are the key 3 to 5 parameters in your opinion to be evaluated / addressed
Your views about various brands such as Trane, Carrier, Bluestar, Danhum Bush
Any other that you feel most important

Upto 100 TR - Recips
100 - 300 TR - Screws
300 TR and above - Centrifugals
Basically centrifugals are the best at part load efficiencies and capacity control is superior. Unlike Recips, screws have step less control.
Some points to check are
1. Part load efficiency
2. Specific power consumption (at various loads)
3. Ease of maintenance
4. Availability of services and spares
A simple fact about refrigerants
One chlorine atom breaks ozone and converts it to oxygen for 180 years before it disintegrates. Rest is your choice.
Don't forget to add York to your list.

Choice of system should also depend on the total capacity requirement, type of application, part load requirements, redundancy, etc.
Carrier has an excellent software program to do an analysis on the right type of system.
On a generic basis, I agree with quark. However, depending on various factors like load pattern, etc., one could opt for a combination of centrifugal and screw as well. Contact a Carrier guy - he can probably help out as well.
