How does the size of the refrigerated trailer affect its power requirements?
The size of the refrigerated trailer is a significant factor in determining its power requirements. A larger trailer will generally require more power to maintain a consistent temperature, as there is more space to cool and more insulation to penetrate. For example, a 28-foot trailer will require more power than a 20-foot trailer, assuming all other factors are equal. This is because the larger trailer has more cubic feet of space to cool, which requires more energy to maintain the desired temperature.
In addition to the size of the trailer, the type and quality of insulation used can also impact power requirements. A well-insulated trailer will require less power to maintain the same temperature as a poorly insulated one, as less heat will be able to penetrate the trailer. Furthermore, the type of goods being transported can also affect power requirements, as different products have different temperature and humidity requirements. For instance, a trailer transporting frozen goods will require more power to maintain a consistent temperature than one transporting chilled goods. As such, it’s crucial to consider these factors when determining the power requirements for your refrigerated trailer.
What type of power sources are available for refrigerated trailers?
There are several types of power sources available for refrigerated trailers, including diesel-powered generators, electric standby power, and shore power.
