Abstract
Article is devoted to increasing efficiency of heat supply systems. We demonstrate research results and an analysis of dependences of overall heat supply system performance indicators at various levels of equipment of consumers with the automated individual heating substations.
Highlights
The system of heat supply is effective if: there is no heat carrier over expenditure and, there is no over expenditure of electric energy during its transfer; the hydraulic operation mode of district heating networks is stable; the operating and capital expenditures caused as a rule by inefficient functioning of district heating systems are minimal; normative values of temperature in the heated rooms depending on their purpose are maintained [1]
One of the main actions offered at implementation of programs of increase in power efficiency of the cities is installation of the automated individual heating substations (AIHS) on end user nodes
At upgrade of systems through the installation of AIHS, only economic and power effects affecting the end user are taken into account, and there is no full analysis of influence of these actions on the system of heat supply in general, meaning influence on the consumers who are left without the system of automatic control and on an operation mode of district heating networks and the mode of supplying the heat energy from sources of heat supply are not yet considered [2]
Summary
The system of heat supply is effective if: there is no heat carrier over expenditure and, there is no over expenditure of electric energy during its transfer; the hydraulic operation mode of district heating networks is stable; the operating and capital expenditures caused as a rule by inefficient functioning of district heating systems (the large number of accidents and damages of main networks caused by violation of a hydraulic operation mode, the overestimated heat carrier expense in a system, etc.) are minimal; normative values of temperature in the heated rooms depending on their purpose are maintained [1]. At upgrade of systems through the installation of AIHS, only economic and power effects affecting the end user (population) are taken into account, and there is no full analysis of influence of these actions on the system of heat supply in general, meaning influence on the consumers who are left without the system of automatic control and on an operation mode of district heating networks and the mode of supplying the heat energy from sources of heat supply are not yet considered [2]. Because of hydraulic communication of all the elements of a system, unsystematic equipment of consumers of AIHS leads to maladjustment of the hydraulic mode of its work. It has a negative impact on reliability of heat supply and reduces overall performance of heat sources and a system in general
