Workshop in Beijing
Welcome to the Intranet webpage of Annex 31.
Annex 31 workshop in
Zurich, May 19th, 2008.
Some
recent outcomes of the Annex 31 activities have been presented in this workshop.
Annex 31 deals with the topic of "Advanced Modelling and Tools for Analysis of
Energy Use in Supermarkets Systems". It was officially started in January 2006
and is scheduled to remain in force until December 2008. An extension has
however been proposed to the IEA executive committee in order to benefit to the
extensive collection of Supermarket energy use data facilitated by US EPA.
Sweden is the designated Operating Agent, acting through the Royal Institute of
Technology. Participating countries are Sweden, Canada, Germany, United Kingdom
and United States.
The
workshop included presentations of case studies of energy efficient supermarkets
from the United States, Sweden, Germany and Canada. Modelling and simulation
tools used in the energy analysis of supermarket systems have been described and
discussed. Special attention has been paid to the topic of heat recovery and
improving the utilization of the refrigeration system in supermarkets to fulfil
the simultaneous cooling and heating needs.
This
workshop offered an excellent opportunity for those involved in supermarket
systems R&D and design to keep track of the latest developments and to exchange
ideas with other experts in the field.
Current
activity in the annex is devoted to collecting experiences from modelling of
supermarket systems and each country will report on modelling activities as well
as available software (whole supermarket computer models) as well as useful
component models specific to supermarkets.
The workshop were
organized into three sessions over
one-half days dealing with the following.

Workshop in Beijing
Another
Workshop of Annex 31 was held as part of the 22nd IIR Congress of
Refrigeration in Beijing, China the 25th of August 2008. This workshop
presented the R&D
activities and case studies and field tests being conducted by the Annex member
countries.
The workshop was co-sponsored by Commission E2 of the International Institute of
Refrigeration (IIF/IIR). The workshop were organized into two sessions over
one-half days dealing with the following.
