Abstract:V prispevku je opisan postopek določitve optimalne debeline izolacije cevovodov za transport hladilnega sredstva. Izračunana optimalna (ekonomska) debelina cevne izolacije je odvisna of izbrane ekonomske metode ter tehnično-ekonomskih podatkov. Na podlagi znanih postopkov za izračun ustaljenega toplotnega toka skozi izolacijo cevnih sistemov za transport hladilnega sredstva in v prispevku opisanega ekonomskega izračuna je bila izdelana računalniška aplikacija. Numerični algoritem, ki je bil izdelan v ta namen, omogoča izbiro med statično in dinamično ekonomsko metodo. Izračun optimalne (ekonomske) debeline toplotne izolacije hladilnih cevnih sistemov se je z izdelavo uporabniško prijaznega računalniškega postopka poenostavil, vendar se od uporabnika kljub temu zahteva osnovno znanje prenosa toplote in ekonomike.

Title:The determination of the optimum insulation thickness of pipe systems for transporting cooling media
Abstract:In this paper we present a procedure for determining the economic pipeline-insulation thickness for the transport of a cooling medium. The calculated economic (optimum) pipe-insulation thickness depends on the chosen economic method and the technical-economical data. A computer software application has been developed using the known procedures for the calculation of stationary heat flow through the insulation of pipe system for cooling medium transportation together with the economic calculations described in the paper. The numerical algorithm developed for this application enables a choice between static and dynamic economic methods. The calculation of the economic heat-insulation thickness of cooling pipe systems has been simplified with the development of a user friendly computer application, but in spite of this, the user of this application must have a basic knowledge in the field of heat transfer and economics.
Keywords:cooling media, pipelines insulation, heat conductivity, insulation thickness
