Embodiment Construction

[0030] figure 1 An embodiment of a refrigerated cargo container 10 is shown in FIG. The cargo container 10 is formed in a generally rectangular configuration having a top wall 12 , a directly opposing bottom wall 14 , opposing side walls 16 and a front wall 18 . The cargo container 10 also includes one or more doors (not shown) at a rear wall 20 opposite the front wall 18 . The cargo container 10 is configured to maintain the cargo 22 inside the cargo container 10 at a selected temperature by using a refrigeration unit 24 located at the container 10 . The cargo container 10 is mobile and is used to transport cargo 22 via eg a truck, train or ship. The refrigeration unit 24 is located at the front wall 18 and includes an evaporator 32 that receives an airflow 34 from the interior of the cargo container 10 ( figure 2 shown in ) and cools the airflow 34 via heat energy exchange between the airflow 34 and the refrigerant flowing through the evaporator 32 . The cooled airflow ...

Abstract

A transportation refrigeration unit includes an evaporator circulating a flow of refrigerant therethrough to cool a flow of supply air flowing over the evaporator, a first compressor operably connected to an engine and driven by the engine, a second compressor operably connected to a battery and driven by the battery. The first compressor and / or the second compressor are in fluid communication with the evaporator to compress the flow of refrigerant and configured and connected in parallel with one another. A condenser is in fluid communication with the evaporator and the first compressor and / or the second compressor.

Description

Background technique [0001] Embodiments herein relate generally to "all electric" transport refrigeration systems, and more specifically, power sources for such systems. [0002] Generally, cold chain distribution systems are used to transport and distribute goods, or more specifically, perishable and environmentally sensitive items that may be susceptible to temperature, humidity, and other environmental factors (referred to herein as perishable items) . Perishable items can include, but are not limited to, fruits, vegetables, grains, beans, nuts, eggs, dairy, seeds, flowers, meat, poultry, fish, ice, and medications. Advantageously, the cold chain distribution system allows for the efficient transportation and distribution of perishable items without damage or other adverse effects. [0003] Refrigerated trucks and trailers are commonly used to transport perishable items in the cold chain distribution system. A transport refrigeration system is mounted to the truck or tra...
