Hi

Just a quick one, air conditioning in one of our offices is now switched on and works fine. A mewmber of staff has complained that it is making her eyes sore. I am not an expert in this area and as such before I go back to them I would like some advice as to what can be done, apart from switching it off that is !

Would plants in the room make any difference, just a stab in the dark?

Cheers

Phil

if it is a cassette unit the it probably will, particularly if she wears contact lenses and they dehumidify the air in the evaporator, you could move her away from it possibly

Typical cassette type installation in the ceiling, thanks for that info. I will see if she can relocate to an alternative area, perhaps outside !

Try resetting the automatic venting to see if you can re angle; reduce fan speed if possible; perfect solution is as stated above, move the person. A/C air per se is unlikely to be the cause of any eye irritation, what is probably causing it is what the air is moving. Similar event last week at another site and lo and behold on investigation, window was opened, fields being cut outside and person is a hay fever sufferer, eyes streaming, sneezing, blamed A/C. Once window shut and asked to see medic about condition and no surprise AH was prescribed, complete cure and all and sundry quite happy; there is usually a root cause (sorry, I was looking for another phrase) and I doubt that it is the air handling unit.

it's not a AHU it's a split ac unit. some AHU's have humidification capabilities built ans because the duct in fresh air dryness is less of an issue

Dry air is a side effect of split units they recycle and dehumidify the air, that's why we fit drains to them. If the person is susceptable to Dry eyes for another reason this will make it more pronounced.

Indeed air flow will also have an effect hence the suggestion to move

This office is on the Marylebone road in London, no fields in site, mores the pity ! Probably the pollution from outside slowly choking everyone whilst they sit at their desks !
