What made Jones's refrigeration unit fundamentally superior to older methods of cooling?
Answer
It was automatic and self-contained
The defining innovation of the transport refrigeration system developed by Jones was its ability to function automatically and independently. Unlike previous systems that required manual oversight and relied on melting ice blocks, Jones created a mechanism that could maintain a set temperature continuously without human intervention, which drastically improved the reliability of long-distance transport.
