Examination of control of the flow temperature in central heating systems. Experience and savings gainedP. Mørk
A central heating and cooling system comprising two independent circuits of the singe-tube type, a cold circuit which is coupled with its outgoing and return lines to a central cold-production machine and a hot circuit, also with outgoing and return lines coupled to a boiler or boilers, or ...
Date Jul. 30, 1987.In order to control the tightness of a central heating system (10, 11) which may be connected to a district heating system (1, 2), the system is provided with a flow meter (8, 9) and a valve (6, 7) in the flow (3) and return pipes (4), respectively. ...
Heat flowGeothermal gradientCentral AnatoliaThe objective of this study is to determine the crustal thermal regime of Central Anatolia Province and its relationship with regional tectonics. Investigations include new temperature-depth measurements in wells, calculations of geothermal gradients from new and ...
Each heating unit in a one-pipe gravity-flow system has a single pipe connection through which it simultaneously receives steam and releases condensate. All heating units and the end of the supply main are sufficiently above the boilerwater lineso that condensate is able to flow back to the bo...
