The four subgroups of tools shown in Figure 1 are designed to assist the engineer of a refrigeration system right from the phase of choosing the overall process design to evaluating the commissioned refrigeration system. The different subgroups will be described in the subsequent C-Tools D-Tools S-Tools E-Tools Cycle Design Dimensioning of System Simulation of Operation Evaluation of Operation paragraphs. The fifth category contains Accessory tools. EES-CoolTools have been divided into five subgroups: Tools for Cycle design, for Dimensioning of components, for System analysis and for Evaluation of system performance (based on measurements). The same simulation model (tool) can serve more purposes as each tool allows flexibility in choosing specific input-variables to describe a certain phenomenon. This is made possible by defining a number of specific simulation purposes. The tools are designed to give the user exactly the right quantity of information with a minimum of input information required. EES-CoolTools Overview EES-CoolTools are developed for end-users and not for modellers who wants a lot of freedom to manipulate the equation system constituting the mathematical model. Dynamics EES-CoolTools and Refrigeration Utilities form the major part of the programs while Dynamics still is in its early stage of development. The programs can be divided into 3 main groups: 1. CoolPack consists of a number of programs which all can be accessed through a user-friendly interface. By using the programs in CoolPack the engineer has the possibility to evaluate different solutions and is thereby getting an opportunity for improving the energy-economics. Today, most engineers do not spend much time on energy optimisation when designing a new refrigeration system due to lack of efficient methods and computational tools. Introduction The overall purpose of developing CoolPack is to assist engineers and users of refrigeration systems in the process of designing and utilising refrigeration systems more energy efficiently. The purpose of this article is twofold: Introduction to the use of CoolPack and presentation of some of the related technical issues of modelling and layout of user interface. CoolPack is freeware and can be downloaded from Users without access to the Internet can contact Team CoolPack by using the address stated in the last paragraph. The Danish Energy Agency finances the project. CoolPack is developed at the Department of Energy Engineering at the Technical University of Denmark. 1 CoolPack Simulation tools for refrigeration systems Team CoolPack, Department of Energy Engineering, Technical University of Denmark CoolPack is a collection of programs used for energy analysis and optimisation of refrigeration systems.
