The options of waste heat utilization in a building of medical product’s manufacture
Abstract
This article examines the possibilities of using waste heat in a building for the production of medical products. During the production, 6 compressors operate continuously, and the generated excess heat is removed through coolers or partially used in building heating, ventilation and domestic hot water production systems. The aim of this article is to model and evaluate the possibilities of using waste heat after performing the analysis of heat flow demand of all the engineering systems. The pinch method is used to achieve this goal. Heat flows and heat exchanger network are modelled using PinCH 3.0 software. The performed assessment shows that with the help of pinch analysis, in the analysed object it is possible to recover and use more than 20% of waste heat as compared to the initial design variant.

Atliekinės šilumos naudojimo galimybės medicinos priemonių gamybos paskirties pastate
Santrauka
Straipsnyje nagrinėjamos atliekinės šilumos naudojimo galimybės medicinos priemonių gamybos pastate. Gamybos metu šeši kompresoriai veikia nuolatos, o jų generuojamas šilumos perteklius šalinamas per aušykles arba iš dalies naudojamas pastato mikroklimatui palaikyti sistemose. Straipsnio tikslas – atlikus visų inžinerinių sistemų šilumos srautų poreikio analizę, sumodeliuoti ir įvertinti atliekinės šilumos naudojimo galimybes. Tikslui pasiekti taikomas „Pinch“ metodas. Šiluminės energijos srautai ir šilumokaičių tinklas modeliuojamas naudojant „PinCH 3.0“ programinę įrangą. Atliktas vertinimas parodė, kad pasitelkus „Pinch“ analizę, analizuojamame objekte įmanoma atgauti ir panaudoti net iki 20 % daugiau šiluminės energijos, lyginant su pirminiu projekto variantu.
