OREANDA-NEWS. July 1, 2011. In order to improve consumer heat supply specialists of Yenisei TGC undertook an analysis of thermal resources usage efficiency levels with residential houses in Krasnoyarsk, Kansk, Minusinsk and Nazarovo. Relying on the data obtained one issued instructions to eliminate inconsistencies to housing and utility organizations wherewith low heat takeoff facts were registered. One elaborated new modes of hydraulic load on the mixing valves of buildings ensuring the required comfortable atmosphere indoors.

During 2010/2011 heating season, within the framework of energy efficiency enhancement program, Yenisei TGC undertook control measurements of inlet and outlet delivery water at consumer houses. If the temperature of water returned to the heat sources is in excess of the rated value this is indicative of low heat takeoff within the residential premises concerned. This means that the intra-house networks have failed to draw off the required amount of heat and returned the resource to CHP, air inside the residents’ apartments remaining too cool.

In such situations the heat source has to supply delivery water in volumes greater than actually required to maintain the rated indoor temperature. This necessity, accordingly, increased load on the plant equipment and costs of the latter repairs.

In accordance with the energy efficiency enhancement principle, the housing and utilities organizations, following the instructions already issued by the heating inspectorate of Yenisei TGC, will be obliged to eliminate the inconsistencies detected, undertake valves inspection and quality flushing and adjustment of intra-house heating systems by the heating season beginning.

Subject to implementation of these measures by the housing and utilities organizations will be timely connection of houses to the heat supply system in the coming heating season. Yenisei TGC is intent on application of penalty sanctions to and utilities organizations that neglect preparation of intra-house networks for winter season and default requirements as to the maximum rated temperature of return water.
