This invention relates generally to refrigeration systems, and, more particularly, to transport refrigeration system.
BACKGROUND
A conventional transport refrigeration system typically includes a refrigerant compressor, a condenser, a main evaporator and one or more remote evaporators connected via appropriate refrigerant lines in a closed refrigerant flow circuit. The refrigeration unit is powered by either vehicle engine or from external power supply. The refrigeration unit may include a housing mountable to the exterior of the: front wall of the transport container of the vehicle with the main evaporator disposed on the interior of the front wall such that the air may be circulated over the evaporator coil by means of an evaporator fan associated with the evaporator coil. The refrigeration unit must have sufficient refrigeration capacity to maintain the goods stored.
The refrigerated container may have one or more temperature controlled regions with a partition. Each temperature controlled region may have at least one remote evaporator unit. The placement of remote evaporator unit in the temperature region is such to have substantially uniform cooling in said region. The partition(s) may be removed to increase the storage space of one or more compartment(s). However, it is not possible to move one or more remote evaporator on removing one or more partition. This may result in uneven temperature within the combined temperature region. To achieve substantial cooling, one or more remote evaporator should be relocated to other partition, if one of the remote evaporator is turned off N vyherrthe ptgq;i£un loaded;, N N AI 2 9 / G 8 / 2 0 1 7 14=59

It is an objective of the disclosure to address one or more drawbacks listed above.

the refrigeration system 100 may have a refrigeration unit 110 and one or more evaporator units 112, 114, 116. The refrigeration uni'tll 10'may include at least one refrigerant compressor 118 and at least one condenser/gas cooler 120. According to an embodiment, at least one evaporator unit 112, 114, 116 may be placed inside the refrigeration unit 110. According to another embodiment, the refrigeration unit 110 may be a conventional refrigeration unit of a refrigeration system 100.-The refrigeration unit 110 may be connected to one or more evaporator units 112, 114, 116 through refrigerant lines (not shown) in a closed refrigerant flow circuit. According to anembodiment, all the evaporator units 112, 114, 116 may be connected to a single refrigeration unit 110.
. The refrigeration unit 110 may be located outside the container 102 and the evaporator units 112, 114, 116 may be provided inside the container 102. According to an embodiment, the number of evaporator units 112, 114, 116 may be proportional to the number of compartments
. 104, 106, 108. As illustrated in figure 1, the container 102 may have one evaporator unit 112,
.114, 1.16, positioned in each compartment 104, 106, 108. According to an embodiment, one of .
the evaporator unit 112 may be fixed in one of the compartment 104 and the evaporator units
114, 116 may be movable in other compartment 106, 108. According to exemplary
embodiment, the fixed evaporator unit 112 may have a higher cooling capacity than the other
' movable evaporator units 116, 118. The compartments 104, 106, 108 may have at least one removable partition 122, 124 between two consecutive compartments 104,106, 108. According to an embodiment, the partitions 122, 124 may be movable horizontally along the length of the container 102 and along the width of the container 102. According to another embodiment, the partitions 122, 124 may be detachable from the container 102.
