The Role Of Numerical Modelling In
Development Of New Refrigeration Systems
And Equipment
Author(s)
B. Pavković
Abstract
This paper presents trends in the application of numerical models for analysis
and development of new refrigeration systems and equipment. The application of
empirical, theoretical and fundamental principle algorithms and models is
discussed. Features of steady-state, quasi steady-state and transient models are
analysed and examples are presented. Application of system simulation
programs and design programs is discussed.
Keywords: models, algorithms, numerical simulation, refrigeration.
1 Introduction
Number of papers dealing with numerical modelling and simulation has been
increasing during past two decades due to increased computer power which
makes possible faster calculations within reasonably acceptable time. In order to
get the information on the present state of activities in modelling and simulation
of refrigeration equipment, the search was performed for keywords \“numerical,
modelling and simulation” in a Fridoc database of International Institute of
Refrigeration (IIR). Fridoc contains over 75.000 references concerning articles
and books on all refrigeration application sectors published since 1982 and data
are derived from all international literature in these fields (journals, conference
proceedings, books, etc.) [1]. Results of search have shown that more than 5400
items had been published till 2005.
Distribution of total number of papers in Fridoc database for last 15 years is
presented in Fig. 1, and it is compared with increase of CPU power related to the
state in 1989 evaluated according to data taken from literature [2]. It is obvious
that the huge increase of numerical modelling and simulation of refrigerating
