can you guys list any product brand you know and the figure of efficiency at the condition about ET(evaporating temperature) 4 centidegrees and CT 35 centidegrees?

i need this to make decision.

you would probably be looking at something with heat recovery like the Daikin water cooled chiller with an additional plate exchanger for the condenser side which you can heat your sanitary hot water with, so you may want to have a look at that option.

What size and location because an ammonia water chiller on a screw compressor with variable vr and VFD would prbably be the best effciency wise but if ammonia is not your thing the daikin chillers are quite good and have allsorts of efficency optimisers. oh and halls or york or grenco for the ammonia is probably best in the uk, in us probably vilter or mc quay or daikin.

I does not make sense do define a water cooled chiller on evaporating and condensing temperature. The easier way is to compare the Eurovent listed datas of the chiller EER and ESEER. Those datas are approved and show the chiller efficiency at +7°C/+35°C. The very best watercooled chillers reach energy efficiency A which is 5.05 (kW cooling / kW power absorption) or higher. There are a couple of chillers out there who achieved that.
