Custom Freezer plate system

​ I know, it looks kinda ghetto rigged, but i dont want to make it pretty until i get all the bugs worked out. So ive building this system for about a month. Heres the basics, 18 plates, 1/4th inch evap coils 9 Circuits, 2 plates per circuit 3hp -40 Condenser unit EEV with controller, Temp sensor, pressure sensor 3/8ths in, 1/2 out 9 circuit refrigerant distributor, 1/2 in and 9 circuit 3/16th out So I did a test run last night, the suction line is getting to -24c and maxing out at that temp, i think there is a slight amount of liquid returning to the compressor, So ill be installing a suction line accumulator. 3 of the top circuits arent reaching freezing temps, which i think has something to do with the suction line assembly, i might need to split the suction line into 2 sections, 4 circuits on the top, and 5 circuits on the bottom. If that doesn't work, then ill be replacing the 3/8ths refrigerant distributor with 5/32 inch circuits instead. Which 5/32 was my original design but the dum dums over at the fabrication place made 3/8ths circuits instead of 5/32 ​ So, what do you guys think? the 3 top circuits are most likely a suction line problem? https://preview.redd.it/0p7vqtp4llh51.jpg?width=1200&format=pjpg&auto=webp&s=7d49a22b747d21d478e5d9dde79fb0a3fff27dfe https://preview.redd.it/ah4j5os4llh51.jpg?width=1200&format=pjpg&auto=webp&s=84ef2c75fba5b85e1bdacd1cc8fd8613555d61cf https://preview.redd.it/j9d4jvp4llh51.jpg?width=1200&format=pjpg&auto=webp&s=18e31702dc554d3edbbd40cb93ecfaee7365f964 submitted by /u/jaybanin0351 [link] [comments]
