I had just started working for a giant grocery chain.
I walked into fist shift only to find most people all worked up.
It turned out that one of the freezer aisles had stopped working overnight. An entire island of food, both sides of the freezer aisle, was ruined. Me and others got to work cleaning out all of the food and melted ice cream and the manager mentioned that she called a Heating and Air Conditioning company. I questioned her and said that it feels like the a/c was working fine. I though Heating and Air Conditioning was only for a/cs and boilers and such. She set me straight. She informed me that the industrial freezers and refrigerators work the same way the a/cs do. The have giant immense compressors that channel literally frigid air into those areas behind the glass doors where my associate and I keep all of the frozen food. Some Heating and Air Conditioning companies also work on industrial freezers. And that is who she called. I was amazed, I had no idea that they worked that way but it makes sense. I’ve never really thought about it buy my refrigerator at apartment works the same way that an a/c does: it has coils filled with a special chemical. These coils compress the chemical creating frigid chilly temperature which are then transferred into my refrigerator. I don’t understand, exactly, how this works but I know a/c compressors work the same way. No wonder industrial freezers need industrial sized a/cs, and not just a few coils on the back like a apartment refrigerator has, to keep the air cool.
