I did actually google this and didn't find anything definitive - I am sure the smart cookies of Geekzone can chime in!

When using your heat pump/AC split-unit to cool your house, what is the optimal setting and angle for the louver/blades?

My theory is that given hot air rises, one should aim it almost out in a straight line to cool the hot air at the top of the room which should cool and sink, drawing the warmer air upwards and creating a sort of cooling convection. This way, although you don't feel the cold draft of air directly on yourself, it should get the room to an overall pleasing temperate fairly quickly and maintain it efficiently.

...this may well be utter nonsense, so I throw it to you guys: Swing Louver? Fixed? Pointing Up/Down/middle?

Ours faces up, and slightly to the left so the cool air goes towards the bedrooms down a hallway.

I find if I dont have them on swimg that condensation will form on them and then drip off them onto things below. So swing it is.

Our Fujitsu split system runs pretty much on auto for the fan and swing setting.

When running as an aircon unit, it pushes the air straight out as you described above. When running as a heater it pushes the air almost straight down.

I guess the people who designed it knew best how to direct the air to get it running the most efficient.

when cooling I aim out flat across the ceiling, so the hottest air is cooled first

When heating, I aim on a 45 degree angle so it both blows out, and down to try and mix with the cooler air near the floor. We dont want the air to blow straight down, rise and then get sucked back through the heatpump without mixing with the air further away.

Cool air will never rise unless you can blow it. So yeah as high as you can get should cool the biggest area. Only issue is sometimes the distribution of cold isn't so uniform. We had a crowd in today, I had to set it to oscillate so everyone got a bit of cooling.
