Refrigerated Unit – How it Works

In light of the recent bill passed on sanitary food transportation, it only seems fitting to delve deeper into how the trailers that transport these items function. Today’s entry will focus on how refrigerated trailers work.
How It Works: How Refrigerated Trailers Work
A refrigerated trailer is considered a closed system and has three main components that help it properly maintain temperatures. These three components are the compressor, the condenser, and the evaporator.
The compressor works by drawing in gaseous refrigerant, and compressing it. This process liquefies the gas, and heats it up. The liquid is then sent to the condenser. The condenser receives the liquid, and cools it similar to how a radiator cools an engine. This is done by bringing the liquid through the outside fins of the trailer and sending it past a condenser fan. This more cooled liquid is then sent into the evaporator, which is located on the inside of the trailer. The evaporator expands the liquid to reform back into a gas. The trailer then cools itself by giving up some of its heat to the cooler evaporator. This process then repeats itself until the trailer reaches its desired temperature.

One thought on “Refrigerated Unit – How it Works

  1. It’s interesting to know that refrigerated trailers use a gaseous refrigerant to provide the cooling temperature inside it. I’ve been curious as to how they work since I’ve noticed that they don’t have to be connected to electricity in order to run. I think that most people who are involved in the food industry might be using this, so I’m sure that they rent or buy these.
