Process description
The present data refer to storage
at roomtemperature in wholesale in Sweden. The technology is unknown.
Data collection
and treatment
Data are derived from a
literature review
by Carlsson-Kanyama (2000).
The energy consumption,
Ep for storage of a given product at room temperature can be roughly
estimated by following formula:
Ep
= Es × Mp × t
Where
Es
is the specific energy consumption of storage room (MJ per kg
per day). See below.
Mp
is the mass of the considered product (kg).
t is
the time of the storage (days).
Technical
scope
The present data include electricity and heat consumption for storing
products at roomtemperature in Sweden.
Representativity
Although the Swedish climate is somewhat colder than the Danish, the
data supposedly provides a reasonable order of magnitude of exchanges
associated with storage at room temperature in Denmark.
Validation
Data
have not been validated.
Inputs
and outputs
Electricity
and heat consumption associated with storage at room temperature in
wholesale. 5-10% of space is used for products.

For determination of impacts
associated with food
products
ex retail, it
has been assumed that products such as flour, oat flakes,
vegetable oil and sugar occupy space for
three days in wholesale while bread occupy space
in one day.
