The possibility of combined regulation of heat supply systems as the basis of energy efficiency

Academic journal Industrial Machine Building Civil Engineering, 2022
The analysis of existing heating systems, as well as methods for regulating heat supply systems at the place of regulation and its parameters, was carried out. In order to maximise the efficiency of heat consumption, combined regulation should be provided, which should include local regulation and individual regulation in addition to central regulation.

Mathematical Model of a Trombe Wall in Combined Heat Supply System

IOP Conference Series: Materials Science and Engineering, 2020
Abstract This article is devoted to the problems of Trombe wall application in the combined heat supply system of a building. The main problem of Trombe wall application in the cold climatic conditions is heat losses. This article represents a new design solution for the Trombe wall, which allows to reduce heat losses with no impact on ...
