How to reduce energy consumption of refrigerated container?

Available literature shows the number of solutions to reduce energy consumption of refrigerated container. These solutions refer, i.e., to adaptation of the terminal layout (Geerlings and van Duin 2011), electrical han-dling equipment usage (Yang and Lin 2013), and inte-grated scheduling of cranes and trucks (He et al. 2015).

How to evaluate the energy consumption of a refrigerated container?

In order to evaluate the energy consumption of the refrigerated container, the cooling load on the refrigerated containers is assumed to be energy exchange across the refrigerated wall and perishable goods, which is equal to the power consumption of the refrigerated unit. Many environmental factors influence the amount of thermal exchange.

Can a refrigerated container be stored in a port terminal?

You have full access to this open access article The article presents the concept of innovative technology used to store refrigerated containers in port terminals or on ships that aims to reduce the energy consumption. The idea of new technology to store refrigerated containers was described on port’s terminal example.

How much electricity does a container refrigeration unit use?

Depending on guidelines of the manufacturer of container refrigeration unit, its technical condition and the required temperature level in the box, the average power consumption in 40′ container ranges from 6 to 9 kW (Reefer container 2017). It means that the daily average consumption of electric energy from container will reach 180 kWh.

Why do refrigerated containers use a layer of phase change material?

In this context, the use of an external layer of phase change material (PCM) on refrigerated containers was found to result in a reduction of peak heat load and daily total energy consumption. The PCM absorbs heat during its melting phase and releases it into the environment, providing high thermal inertia to the container.

How do refrigerated containers work?

On-deck refrigerated containers are generally serviced by clip-on or integrated air-cooled electric motor drive cooling units. The units are plugged into the ship’s electrical system by way of suitable deck sockets. Similar water-cooled units have been used for below-deck containers on short-haul voyages.
