The link above for the 2007 ASHRAE Applications Handbook, HVAC Applications seems to be broken.

Dear all, I am currently working on a project with a VRF system. We have contacted the manufacturer for non-default refrigerant leakage rate values.

Dear all, I just wanted to double check that the VRF system lifetime is 15 years (considered a packaged AC). Is this true? Thanks,

I have about sixty-five split systems in two apartment buildings using R-410a. The factor that is keeping me from meeting this credit's requirements seems to be Rc (lb/ton).

The link for explaning Greenhouse Effect explained and illustrated under publications is not working. Dave

Hi all, Currently we are working on a project which does not have a fire suppression system, but is trying to achieve "Enhanced refrigerant management" credit in LEED NC 2009. In the LEED online fo

Here's a stumper for y'all. A "heat pipe" uses refrigerant migration (without compressors) between two coils for heat recovery.

Our system has 2 different refrigerant types. One type in the compressor and another type in the refrigeration circuit.

In a project I'm working on , we are using two heat pumps for cooling and heating,such that only one heat pump is going to be used during the summer season(cooling) and both pumps are to be used in
