Analogy; I'm on a sinking ship and pumping out bilges as fast as
possible; there are leaks everywhere, the lower the ship gets in the
water, the more pumping is needed.

Actual situation; the ship is a house, the water is heat.  It has been
a bit hot lately.  Yesterday's maximum 48=B0C 118=B0F, with overnight
minimum 32=B0C 90=B0F.  Maximum has not been below 48=B0C 104=B0F for 32 da=
ys.

Three split-system reverse-cycle air conditioners (Daikin) are set to
maximum fan and minimum temperature (18=B0C).  They increase comfortable
living space, with unused rooms closed and sealed.  They are run
continuously; load varies from 3kW in the morning to 7kW in the
evening.

Floor temperature peaks at 33=B0C 91=B0F six hours after the peak shade
temperature.

So a thermodynamics challenge; does water added by ultrasonic
humidifier increase cooling?  About 3 litres every 12 hours.

The power draw of the humidifier seems minimal.  I'm predicting the
water would take heat from the floor and air, condense on the air
conditioner, and fall outside via a drain.

(The drains are of great interest to kangaroos, wallabies, birds,
wasps and bees.  One is a favourite of the bees; they are lined up
side by side, taking turns, about twenty of them at a time, and
there's a flight path off into the forest.)

Also, do systems with heat pumps benefit from thermostat cycling?
