Cavemanthe0ne Posted November 8, 2015 Share Posted November 8, 2015 As per the title, I have a 10k BTU AC unit, which needs a minor repair & then it will be set to go for extreme cooling. (Someone decided it would be a great idea to drill a hole in the bottom and punctured one of the copper tubes on the side of one of the rads, so will be a minor fix). Since I'll have to refill & fix the thing anyway I figured that a Phase Change cooler was in order... What do I need, and where to start? (Heres a pic of the unit with the cover off: ) Quote Link to comment Share on other sites More sharing options...

nachtfalke Posted November 8, 2015 Share Posted November 8, 2015 first check your compressor if is for R407c( low back pressure) refrigerant , 10k btu compressor design for R407c will had ~ 18-19 cm3/rev cilynder displacement ... that is what you need for a phase change! if the compresor is for R410a( hight back pressure) refrigerant , 10k btu compressor design for R410a will had ~ 11-12 cm³/rev cilynder displacement , so used in low back pressure application like oc phase change with low back pressure refrigerant R502 , R404a or R507 isn´t so good!
