Default Re: Evaporative cooling vs reverse cycle. Thoughts?

In my house we have two inverter systems, the main unit is a 7.8kW Mitsubishi Heavy Industries, whilst the one in the main bedroom is a smaller inverter of the same make, somewhere around the 4Kw size.

The main unit replaced an old window box unit and despite it being twice the size and running 3 to 4 times longer, our electricity bill was no greater in size. The large unit is quite capable of cooling the lounge room dining room and kitchen all in one go but the small unit is really only good for the bedroom (5m x 8m) yet it can be run at low setting all night without much noise or cost.

When you do go to install any split unit make sure that the outside unit is in a shaded area. The cooler it is the better it will operate.
