| Refrigerator with two compressors - How do they do it? |

Guys, thank you for your comments. We have a Samsung refrigerator and it often breaks, especially I am concerned that the icemaker breaks every 2 months and I am tired of fixing it. I decided we'd better spend a little more money and buy a good refrigerator. If you can recommend a good refrigerator, I will appreciate your advice. During the research, my attention was drawn to this site ianboer.com.au. I liked the characteristics of the refrigerators they have, if anyone has had experience buying an industrial refrigerator, please let me know. |

(Despite their age, they are actually extremely efficient. Used ones in working condition sell for astronomical amounts.) |

Its what is called a cascade system . were the second compressor acts as the condenser of the first stage . I have not see one of these for over 40 yrs . each system will have a different gas .in our old lab we had a freezer for testing equipment to work @ -60 c for ships working in the antartic it used B13a and R13a . B13a was a custom gas . they both have different properties and are quite difficult to set up so both systems are balanced. There are a few different gasses that these system work with . Your diagram is correct but you need a tech that works with these units . Warning be careful one stage will have R13 it is very high pressure and I believe its been banded now . I actually built a few of these sub cooling fridges in the 70 & 80 for the company I worked for . each one is custom built for the customer. I guess this freezer is not 40 yrs old . The newer fridges use R*** A butane derivative |
