I am too old for ECOTEC. Yet, I would tend to reply to your question with some principles:
- cooling is not just to put the air temperature down; cooling is first of all, avoiding that the air becomes too hot and, that, basically, walls are massive and kept with low temperatures in the daily cycle (eventually, cooling down them at night);
- cooling with dry air is much easier; so, try to find your own equilibrium between humidity and temperature level
- thermal comfort is also info and culture and never technology. USA caused a big prejudice to all of us believing and imposing the HVAC (I'm Fellow of ASHRAE!) in a necessarily hot and humid climate. That is the worse condition. Japanese and Guiana people, to cope with that in the past, used walls made of permeable tissue. So the air movement (air inside) at night could have an evaporation effect at the skin level at night which was promoting better comfort, even if not, THE comfort....
Sorry I did not respond. I just tried, a bit like a medicine doctor, to make a diagnostic of situation of some discomfort not requiring a 'hard engineering' , that is a 'hard medicine'...
