Vilniaus TE-2 mechaninio cecho apšiltinimas ir šilumos sąnaudų jame mažinimo galimybės

Abstract

Mechanical shop of Vilnius TE-2 is one-floor building, height 7.3 m, without ceiling. A lot of heat is being lost through the roof and big windows. In order to save heat and decrease these losses we suggest to install intermediate ceiling using PV-AIM rockwool mats covered with glass fibres or to implement polietilentereftelat pellicle into windows. It was created a room heat balance for building and its renovation. It was calculated that needed heat energy after ceiling installation would decrease from 11.724 to 4640 W. After installation of recirculating air heating and ventilation systems 1051 GJ or 23.877 Lt would be saved per heating season.
