sorry i was not clear, we do not do heating in the industries we work in, internal heat is always dominant. i have no experience of thermafuser performance in heating. rgds leelock

we have used thermafusers successfully for many years in cooling-only applications. the adjustments i am aware of require the user to climb up to the diffuser and use a screwdriver to manually increase or decrease the setpoint. definitely would recommend them for normal office use if...

re the 2 x 700tr yorks, at standard ari conditions at this size range york can get to 0.53kw/ton or thereabouts. trane could get to about 0.48kw/ton. however depending on the wet bulb in your region it might make sense to have inverters fitted for the compressors, in which case i...

the answers you want have been debated in papers on the trane.com and york.com website, where trane is proposing 2usgpm/ton for condenser water flow, and york is refuting it. also note that at ari conditions of 44degF and 85degF, the latest trane centrifugal chillers are inching...

it is better to use run-round coil around the main cooling coil, this is two coils, one in front and one behind the main coil. water is pumped around the coils transferring heat from the front of the coil to the rear thus reheating the air for "free". also it is possible...

have u looked at the trane website and studied their proposal to use 2usgpm/ton for condenser water flow? over varying weather conditions this might be interesting option. rgds leelock ps we also ask for max efficiency but get low pressure drops--bigger shell and more tubes.

the precision airconditioning units made for computer room use are almost 100% sensible cooling. the telecoms exchanges also feature almost 100% sensible cooling since the heat is all electrical and there is usually no one in the space. in the semiconductor industry they use dry coils to handle...
