I think I figured out how to make the AC behave less like a cooler, and more like a dehumidifier ... basically running the AC on dry mode at a high-ish temperature, say 28C, and with an additional fan aimed at the present humans.
This is roughly explainable as :
- there is an increased velocity of air flowing against the wet-bulb (bodies)
- ... causing an increase in the rate of evaporative cooling ( correspondingly reduced WBT )
- ... causing an increase in cold-room humidity
- ... causing an increase in the rate of cold-room condensation, upon the evaporator of the heat-pump
- ... causing a decrease in the cooling-capacity of the heat-pump, upon the cold-room
Electrical optimisation for HVAC in the tropics.
Problem statements :
- Humidity is the main problem ... so higher temperatures are acceptable as long as rH is minimised.
- The correct { rH, windSpeed, temperature } results in the absence of noticeable sweat.
- The optimum air temperature is greater than the current tap water temperature, such that unheated showers/baths are able to cool bodies further.
- An acceptable wind speed is non-distracting.
Solution statement :
So to minimise electrical consumption, one targets
- to FIRSTLY maximise non-distracting wind speed, and
- to SECONDLY, design heat pump systems which
- - maximise condensate collection,
- - without raising air temperatures at all, and
- - without excessively dropping air temperatures
