DX or Chilled water for residential refrigeration
Hi,
Previously I was considering DX system for central airconditioning for my residential project (4-5 units x 18000 BTU) on single compressor with VFD.
Upon little survey I saw that chilled water system could also work and maybe more effecient. I belive it would be less mantainance with chilled water as I only have to chill water in a tank and passing water through FCU.
Further technically, I can skip VFD on compressor as if water once chilled could stay chilled for couple of hours or an hour atleast if number of FCU reduced from 4 to 1 (on demand).
Kindly guide me if this project would be more adivcable compared with DX or otherwise?
