type of system is most commonly used for long-distance transportation and the larger rigid local distribution vehicles . This system remains the most popular due to its reliability , efficiency and versatility . As an alternate power source to the diesel engine , solar panels , especially on semitrailers with ample roof space , are being explored as an environmentally-friendly way to power refrigeration units which have electric fan motors and compressors driven by electric motors .
While the use of solar power for refrigerated trucks is still in the early stages , its potential is being recognised as a viable solution for reducing emissions and dependency on diesel fuel . As advancements in solar technology continue , integrating solar panels onto refrigerated vehicles can offer a more sustainable and cost-effective way to power refrigeration systems .
Another system used for local deliveries is the vehicle driven compressor system . This system is often utilised by trucks operating within a town or city . The compressor , which is driven off the vehicle ' s engine , powers the refrigeration system . While this system is effective for local deliveries , it does not provide refrigeration when the vehicle is stationary .
Another option involves the use of liquid nitrogen . Liquid nitrogen from onboard storage tanks is discharged into the cargo space , resulting in cooling . This
|
system is considered to be quite clean and relatively maintenance free , but it requires regular replenishment of the nitrogen supply . Sufficient storage of nitrogen must be available on the vehicle to cover the intended journey and door openings when used on multi-drop routes .
It is worth noting that some refrigeration systems are quieter than others . For example , liquid nitrogen systems and systems driven by the vehicle ' s engine produce low noise levels . This makes them suitable for distributing products to stores located in residential areas , without causing noise pollution during late-night or earlymorning deliveries .
Refrigerated transport will also become increasingly relevant in the final leg of online shopping deliveries . Electric scooters and other vehicles used for home deliveries will require some form of refrigeration depending on the specific products being transported . This will ensure that perishable goods , including ice cream , remain at the required temperature throughout the delivery process .
When it comes to refrigeration for online shopping and temperaturecontrolled products , there are options available , although they may differ from traditional refrigerated transport . Small vehicles , such as refrigerated bakkies , can be used for this purpose .
It is important for retailers to pay particular attention to the cold chain . For example , when selecting products from the
|
store , pickers should ensure that perishable items are immediately placed into insulated boxes . These items should be the last to be picked , given priority in the store , and quickly loaded into refrigerated vans for delivery . However , maintaining the cold chain in this manner requires discipline and careful management .
Research and development in this field relate primarily to energy and thermal efficiency , as well as the international drive to change to natural refrigerants . Ways in which this is assisted through R & D is via remote systems to monitor temperature control . These are areas in which vehicle and container manufacturers are continually innovating .
Other innovations include the following areas :
Enhanced monitoring for accurate temperature control : One significant breakthrough in refrigerated transport is the development of advanced monitoring systems . In the past , mishaps and product spoilage were prevalent due to insufficient checks on container conditions . However , with the advent of modern technology , monitoring systems have dramatically improved , enabling real-time tracking of temperature and humidity levels . This heightened control allows for prompt detection and swift resolution of any deviations , preventing costly product damage .
Automated alerts for efficient incident response : Another notable trend in
|
refrigerated transport is the implementation of automated alert systems . These systems promptly notify operators when temperature or humidity levels deviate from the desired range , ensuring immediate corrective action . By streamlining incident response , the industry has significantly minimised losses and maintained optimal product quality .
Advancements in marine container design : Container design has also undergone significant improvements to enhance temperature regulation during transportation . Manufacturers continue to prioritise insulation and temperature control mechanisms , such as high-quality insulation materials and energy-efficient refrigeration units . These innovations help maintain consistent internal conditions and minimise temperature fluctuations that can affect perishable goods .
The refrigerated transport sector has witnessed remarkable advancements that have revolutionised the industry . From enhanced monitoring systems to automated alerts and sustainable solutions , efforts to improve temperature control during transport have significantly reduced product spoilage and waste . With the continuous development of innovative technologies , the future of refrigerated transport appears promising , assuring consumers of consistently high-quality perishable products across the globe .
