Cím:	Balancing of central heating systems / Kalmár Ferenc, Halász Erzsébet, Csáki Imre
Dátum:	2009
Megjegyzések:	The main goal of the central heating design process is to obtain appropriate thermal comfort minimising the investment and operational costs. This scope could be theoretical realised with the available modern control techniques. However practice has shown that, if the preconditions are not fulfilled the correct operation of the heating system could not be assured even by the most sophisticated control equipment. In central heating systems the warm water forward temperature could have different values. In the near past the most used value in Hungary was 90/70 oC, but nowadays the forward temperature usually is lower. The control elements could not fulfil their duty if the warm water flow differs from the designed value. This situation could often appear in practice because of lack of the suitable balance equipment on one hand and differences between the executed and designed system on the other hand. Therefore the thermal comfort is not realised unless with higher energy consumption. The above mentioned problems could appear even at heating systems equipped with thermostatic valves. In this case the valve opens totally in vain if the required flow is not assured at the radiator, the flow will not increase. In the followings the operation of unbalanced central heating systems is studied.
