HEATING SYSTEM

摘要

construction engineering; heat-insulating block for heating systems. SUBSTANCE: heating system has block of heat-insulating slabs with ducts to receive pipes; pipelines are mounted so that they are supported by walls of triangular- or trapezoidal-section ducts widening upwards, their walls being provided with edged ridges at separate points lengthwise of ducts; ridges are also provided in upper part of block; cycloidal guides are made inside ducts around triangular- or trapezoidal-section pipeline within depression and curvilinear screw-shaped grooves, within ridges; top-to-bottom slab joint is sealed with flexible piping placed in slots formed by two hemispheres. EFFECT: reduced heat loss into environment and reduced corrosion of pipes. 4 dwg
