PROJECT
INCORPORATING COLD CHAIN
Inside one of the freezer rooms.
within an impressive 2mm from one
another before a sensor automatically
stops them.
Next door to the cold rooms is a forklift
room to charge and service the six forklifts
and the 11 ride-on jacks.
The estimated amount of heat
rejection will be around 384kW and this
will be used to heat water from 20°C to
55°C. Hot gas defrost has been included
instead of the normal element heater that
uses a lot of electricity.
“Using heat reclaim and hot-gas
defrost minimises the need for electrical
elements within the store set up, reducing
the overall energy consumption of the
fresh market,” explains Robinson.
The system comprises two refrigeration
packs, each with both the medium temp
and low temp circuits built in.
The citrus rooms are kept at 2-5°C.
