I'm an HVAC enthusiast and an mechanical engineer currently working on a small purpose ICE making machine . I have developed an evaporator tray comprising of ice moulds in it . Tray can hold 4 ice cubes. It is equipped with automatic ejecting mechanism . Considering the technical data,
Heat load = 450 Btu/hr
Compressor selected = Tecumseh HCG1365 (540 Btu/hr)
Air condensor = 9*9 inch , 2 rows , Microfins
Fan :- 1300 rpm, 350 CFM
Capillary length = 1.8m, 0.031" using DANCAP
My target is to make ice in 5 minutes . But it is taking 10 mins . Kindly comment on above configuration system .
Condensor is oversized according to the load but i had it in scrap n used it rather than buying new.
Also it seems capillary length is not correct i suspect. Kindly check on it too.
Thanks, awaiting reply

What refrigerant is being used?

Is the ice tray sprayed with water or has water running through it or just filled with water?
