1 ADVANCED COOLING
Brendon spotted this unit at a service station in Queensland. “The air conditioner airflow didn’t reach the console operator,” says Brendon, “so somebody decided to move it closer.” Graham says: There is a difference between air conditioning and spot cooling. Unfortunately, the budget often gets in the way of doing the job properly. Innovative though!
2 COOLING THE ROOST
At least this unit has some breathing holes, although they look like they were made for pigeons rather than a condenser. Thanks to Adrian for the photo, snapped on a pier in Melbourne. Graham says: Someone has gone to a lot of trouble to “hide” the air conditioner, but the unit will suffer in both capacity and longevity. Would have been a lot better with a water source heat pump than air source.
3 EASY INSULATION
Jay found this “insulated drain” in North Lakes, Queensland. “Pretty rough job to just use clumps of ceiling insulation duct-taped to the drain,” he says. Graham says: Hard to tell from the image, but drain insulation is extremely important in the tropics. Any cold surface will produce condensate which can ultimately collapse a ceiling. Fibreglass insulation that isn’t vapour sealed will just get wet and lose any insulating properties in the long term.
4 FAN TLC
Mitchell was called out to look at this unit when the owner complained about (surprise surprise) a lack of airflow. To their credit, Mitchell’s crew pulled out the fan deck, gave it a full clean, and pressure washed it a few times to get it as good as possible. Graham says: The air we breathe! There would be many fan decks around in a similar condition. We don’t design or budget for maintenance, yet it can become a health issue.
5 PLUG IT IN!
Regular contributor Mick has sent in another classic. “A cool room condenser has been jammed in with some sort of cover,” he says. “But look harder – they had the nerve to tap into the AC power supply with a GPO. Plug it in boys, good as!” Graham says: Interesting and innovative and probably not legal wiring. I would have thought an electrician would not have put his/her licence to that!
