Tools and models

FRISBEE tool: cold chain simulator


Frisbee tool is a software for optimizing food quality, energy use and environmental impact of cold chain. The user selects a specific food product and defines a cold chain. The user can choose default settings or can define the settings of a specific cold chain to the lowest level of detail.

This tool has been developped in the european FRISBEE project coordinated by the research unit FRISE

FLEXIfroid : Demand response for refrigerated warehouse


Demand response (DR) is the voluntary reduction of electricity use by customers, which can help to keep a power grid stable by balancing its supply and demand of electricity. This software tool simulates the impact on food quality, energy use and environmental impact of demand response on a frozen products warehouse.

This tool has been developped in the FLEXIFROID project coordinated by FRISE

Cold room filled with food products

Chambre froide

A simplified heat transfer model for a cold room loaded by pallets


Domestic refrigerator

Fridge model

A simplified steady state heat transfer model developed for a domestic refrigerator


Refrigerated vehicle

Vehicle model

A simplified heat transfer model of a refrigerated vehicle was developed in which two loads (front and rear) are considered. The model takes into account heat transfer by convection between the internal air and the load, between the external air and the walls of vehicle and by conduction in these walls. Air infiltration during door openings is also considered.


GENEPY : thermophysical properties of secondary refrigerants


Cet outil permet d’obtenir les propriétés thermophysiques des principaux frigoporteurs en fonction de leur température et de leur concentration:

  • fraction massique et volumique en glace
  • masse volumique, enthalpie massique
  • capacité thermique, conductivité thermique
  • viscosité dynamique

Freezing time

Freezing time

A simplified steady state heat transfer model developed for predicting freezing time. Main assumptions are: infinite length, linear temperature gradient, constant conductivity
