I know that getting an air conditioning unit that is "too powerful" is bad because the condenser won't run for long enough to de-humidify the room, but is that still true of inverter units that run the condenser continuously on a low setting? The reason I ask is that I was quoted a ridiculous £4.5k to supply and install a double split unit into my office and bedroom, whereas it'd only be £1.5-2k for a single unit (talking about a Daikin or Mitsubishi R32 top-end unit with a 7 year warranty). I reckon 2.5 kW is enough for the office (27 m3, 2 people, 2 computers) so would a 3.5 kW unit still work effectively whilst giving us enough power to open the doors and let it cool a larger area on hot nights (95 m3 including hallways between the rooms)? The other issue is the bedroom is on the floor above the office and cool air sinks so I am unsure how effective it'd be anyway. Any thoughts welcome.

Hello all, i am planning to remove the evaporator from my 5000btu unit and put it in a glycol solution for chilling a beer fermentation chamber. Unfortunately I think some of the ground wires are attached to the evaporator itself. There are 3 wires attached to the evaporator, and I just need to know where I can reattach them once the evaporator has been removed from the casing. I have already bypassed the thermostat so I can control the AC with an external temperature controlling unit. I attached photos of the 3 wires I’m trying to reattach somewhere else. Thanka![left][/left]
