How Refrigerated Trucks Work (Power Sources)

Do you want to keep your ice cream cold on a hot day? Need your medicine safe during a long trip? Hai bisogno di un camion refrigerati. Let’s learn how they work!

Cosa è un camion frigorifero?

Un camion refrigerati, o reefer truck, is like a big moving fridge on wheels. It keeps food, medicine, and other things cool and fresh. These trucks are heroes in the catena del freddo. The cold chain is how your ice cream, milk, or medicine stays cold from the factory to your home.

How Does a Truck Keep Things Cold?

These trucks use a transport refrigeration system. It works a lot like the air conditioner in your car or your home fridge. Here’s the simple way it works:

• There is a compressor. It pumps a cold special liquid called refrigerant.
• The refrigerant goes through the condenser coil. Here, it lets out heat and cools down.
• Next, it moves to the expansion valve. This makes the refrigerant very, very cold.
• Then, the refrigerant goes through the evaporator coil. Here, it takes in the heat from the inside of the trailer.
• Warm air leaves, cold air stays, and your cargo stays just right!

But all these parts need la potenza. So, where does this power come from?

How Do Reefers Get Power? Let’s See Their Power Sources

Camion frigoriferi need energy to keep running. There are many ways to give these systems power:

1. Self-Powered (Independent Diesel Engine)

• Uses a small diesel engine only for the fridge.
• Best for big trailers and long trips.
• Vantaggi: Works anywhere, strong, easy to refuel.
• Svantaggi: It uses fuel, makes noise, and makes smoke.

2. Vehicle-Powered (Direct Drive)

• Uses the truck’s engine to make the fridge work.
• Best for smaller trucks and city trips.
• Vantaggi: Lighter, fewer moving parts.
• Svantaggi: Only works when the truck is on.

3. Electric Standby

• The reefer can plug into the wall for electric power when parked.
• Useful at docks or warehouses.
• Vantaggi: Quiet, no smoke when using electric, saves fuel.
• Svantaggi: Needs special plugs, doesn't work while driving.

4. Battery-Electric

• Uses a big battery pack.
• Charged from a wall plug or when the truck slows down (regenerative braking).
• Great for cities or places with many charging stations.
• Vantaggi: No noise, no smoke, saves money in the long run.
• Svantaggi: The battery is heavy and costs more, needs places to charge.

5. Hybrid

• Uses both a diesel engine and a battery.
• Can switch between them as needed.
• Vantaggi: Saves fuel, makes less smoke, flexible.
• Svantaggi: More parts, may cost more at first.

6. Emerging Power (Future Ways)

• Solar Power: Solar panels can help charge the system.
• Cryogenic: Uses cold liquid, like liquid nitrogen, instead of a fridge motor.

See How Reefers Save the Day!

Let’s look at some fun facts:

• Il global transport refrigeration market was worth about $12 billion in 2022.
• Diesel engine reefers make up 90% of trailers today.
• Using electric standby removes 100% of tailpipe emissions when plugged in!
• Battery reefers are very quiet, which is nice for city deliveries at night.
• By using hybrid power, fuel use can drop by 30%.
• Rules in places like California (CARB TRU regulations) mean more electric reefers are coming.
• Batteries can be heavy, so trucks may carry 500-1,500 less pounds of cargo.

How Smart are Today’s Reefers?

Today, reefer units have brains. They use sistemi di controllo della temperatura, registri di datie persino With no one lifting bins, injuries dropped by over 50%. to keep food cold and send you updates. Some use monitoraggio remoto over the internet. They can even predict when they need a fix (predictive maintenance).

Picking the Best Power for Your Needs

Let’s say you have a job to do. How do you pick the best refrigerator power?

• Long Haul? Use diesel, hybrid, or plug in at stops.
• Short City Trips? Try battery-electric or direct drive.
• Carrying Frozen Food? Get the biggest, coldest unit.
• Worried About Rules? Electric or hybrid helps meet emissions rules.
• Need To Save Money? Compare fuel, battery, and maintenance costs.
