Yesterday I worked in the "ROCKY" 8285WS, cleaning & other small like to do jobs. The temperature here in my part of Florida was 91°. Before starting
work, I turned my A/C on to a thermostat setting of 76°. The temp inside of "ROCKY" was already at 89°. I let the A/C run about 20 minutes on high before I went inside to work. By the time I started, the temperature had already dropped inside to 87°. I worked about one hour, by the time lapse, the temperature had dropped to 78°. I went inside my house to make a phone call & was inside for about 30-40 Min's. When I returned to the inside of "ROCKY" the A/C had turned off at the setting of 76°.
I use the "HUNTER" digital thermostat for a precise reading of temp and control.
What a difference the A/C vent enlargement made to the volume of air flow. Even in the bedroom, there is plenty of cold air @ 49° measured at the vent with a digital thermometer.
The same reading was measured at the last two vents in the living room
in the 8285WS with an internal temp at 82°.
The small openings shown in the pictures create a "AIR TURBLEANCE", restricting the air flow. Just by opening the vent the small amount shown
and sloping the styrofoam creates a faster cool down, recycling the air inside faster to keep the inside cool.
My next project is to use a white plastic rain gutter downspout 90° elbow
trimmed to fit inside the vents to "SMOOTHE" the air flow going into the bedroom and living room. This should create a better airflow, even creating a better cooling system for recycling the air.
To test the project of increasing the air flow, take a small cardboard box, cut a small square hole in the bottom of about 3/4" X 5". Have someone drive your TV down the road at about 25-30 MPH with you holding the small box outside the window. Feel the sir flow. Now take a small funnel or piece of cardboard shaped like a funnel with a opening of about the size mentioned above for the box. Now test the airflow.
Makes sense by increasing the opening from the fan box in the A/C to the vents just by a small amount by "smoothing" the air flow.
I am so pleased with my project of increasing the cooling efficiency of the A/C that today I will do a IGGY by getting into the pool with a cold
