So i thought i would make an Air conditioner from scratch.
The basic system is rectangle box , im using an old esky
Ive put separated The rectangle into to halfs . one for evap and one for condenser .
Ive made copper coils from 1/4 inch pipe . a few meters long .
Im going to use an old freezer compressor to pump the gas around.
The idea of the system is to make to water almost freeze then have a fan blowing out the cold air. The comp would be running as much as a fridge does.
And for the condenser have water slowly flowing through it to take away the heat. A drip every 2 seconds coming out and room temp water coming in from a new bucket.
My question is . Would i be able to use my gauges as a metering device to restrict the refrigerant until i figure out the perfect cap tube ?
Just use the superheat of the evap and close of the gauges until its good?
And i will also need an accumulator after the evap to help hold the charge when the system is not running ?
Also how much gas should i use , i cant find any info in my books that lets me know how much gas i need for the size of the coils .
Ive been working for 7 years , installing splits and vrv welding all day hasent really tought me these things
