Condenser Fan Upgrade on The Sharp Minisplit AC
This is what I've been doing mostly during quarantine; I make stuff that either I don't really need out of things I scrapped, or most people don't even think about making.
Here's the 2nd(and probably won't be the last) condenser fan upgrade I've done on this AC unit. I just can't stop trying to maximize the efficiency of the refrigeration system. The condenser fan motor that came with this unit( https://www.youtube.com/watch?v=1hf9xQMbKLQ ) was far too slow to my liking. I went back to the guy that sold me this unit to swap the original 500 RPM motor to a 990 RPM motor. The 990 RPM motor brought the lowest evaporator temp record from 19°C to 15°C. Add the water sprayers into the equation, and they got the evap to about 12°C.
With the big beefy motor, the evaporator low temp record thing has plunged to 4°C. The air coming out of the indoor unit feels substantially colder compared to when the outdoor unit was still coping with the snail paced 500 RPM motor. Now, the 2 speed National condenser fan motor I put on can deal with a load much heavier than the metal blades currently mounted on it(this motor(and CKE grille) was once used for the window fan in my shop. The blade I had on there was 18 inches in diameter, with 4 deeply pitched blades( https://youtu.be/A_i4qDt_p84 )). So if I can source a deeper pitched fan blade that can fit in the unit, I might be able to get the evap temprature to go below 0°C.
I could almost see the day when I jam in an industrial 12 bladed 3 phase axial drum fan in there. So stay tune for more dumb(well maybe not) upgrades on my AC. I'm planning on making a heatpump for my fan room too so... yeah I think it's safe to say that I'm a fan, & aircon guy now.
