A diesel engine, a refrigeration unit, and their own refrigeration unit are typically included in refrigerated trucks. The vehicle does not deliver anything to the container. It might use many gallons of fuel per hour. Like a home refrigerator, a truck’s freezing unit doesn’t need to be running nonstop. It continues to run until the target temperature is reached, at which point it shuts off. Heat transfer is minimized by the trailer’s good insulation. The refrigeration device restarts cooling down after the interior temperature rises by a certain amount, then turns off once more until another use.
The vast majority of refrigerated trailers in the US are propelled by diesel motors. Numerous factors have a significant impact on fuel economy. Based on the difference between the ambient temperature outside the trailer and the desired temperature, the freezing unit will hold the product excessively within the target temperature range if it is already at or close to the desired temperature at the time of loading. Work is pointless. of the mass. If there is no considerable change in the ambient temperature, the machine can only utilize 5 gallons in a day. If the cargo is frozen, the ideal holding temperature is 0°, the outside temperature is 100°, and it is sunny, the temperature must be maintained by traveling more frequently and using 15-20 gallons of fuel each day. Use more fuel because you can.
For a long time, only diesel was utilized to power refrigerated vehicles. movement of the internal mechanical cooling system components. Although this was successful, adopting an electrical (or hybrid) cooling system to separate these two duties would greatly boost flexibility and cost savings. Keep these three things in mind as you learn about the benefits of electric standby systems for refrigerated containers.
1. Working Principle of Integrated Electric Standby Unit
All integrated electric standby refrigeration units have two compressors that make up their entire cooling system: a road compressor and a standby compressor. A road scroll compressor placed on the engine powers the refrigeration unit while the truck is moving. The device is powered by AC220V/AC380V city electricity while the truck is parked or at night; a rotor compressor is placed within the condenser.
Truck refrigeration units with STANDBY are gaining popularity with customers due to their simplicity of installation, straightforward wiring and hose connections, low failure rates, and the fact that the standby compressor is located inside the condenser. This helps to avoid problems like running out of standby space and water damage, among others. The cargo had to be stored in the truck body at night because drivers couldn’t discharge all of it at once during the protracted travel. Drivers could connect AC220V/AC380V city electricity and instruct the refrigeration unit to maintain the box’s temperature during this period if they didn’t want the engine to run all night.
2. The function of the Electric Standby System
· Maintain Cooling When Stationary
The electric standby system uses a separate battery to activate the compressor, condenser, and evaporator while the engine is not running. The first advantage is that the driver can keep the object cool without running the engine constantly. Because of this, making pit stops is much simpler since the load is no longer an issue. In addition, the car is silent when it is stopped, which helps the driver feel more comfortable during breaks and challenging situations.
· Reduces Fuel Consumption and Exhaust Emissions
Possibly its most important advantages are the fuel savings and pollution reductions offered by the electric standby system for refrigerated containers. Electricity produced by batteries is less expensive than diesel fuel. This suggests that whenever you use an electric standby, you can save money by burning less gasoline. Taking a break from the engine also helps the driver feel less cramped and saves time.
Additionally, using less diesel reduces overall emissions, which is good for the environment. The addition of the electric standby mode thus creates a new opportunity for corporate sustainability. Although it doesn’t really matter to you, certain states have strict emission regulations that you can adhere to while you wait.
· Extends Truck Lifespan
Since the truck uses less fuel and only starts the engine when necessary, its lifespan is often extended. The service interval is a bit longer because the parts last longer and wear less. A vehicle with an electric standby system will run more efficiently and have fewer problems.
