Abstract: 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. Therefore, the control elements could not fulfil their function if the warm water flow differs from the designed value and the thermal comfort is not realised unless with higher energy consumption. We can obtain heating systems with a higher stability and energy efficiency decreasing in the same time the forward temperature and the temperature drop. In this paper is studied the operation of unbalanced central heating systems, and are analysed the thermal comfort and the energy consumption. Also, are analysed the energy savings in heating systems with reduc!
ed forward temperature, for different types of radiators taking into account the thermal insulation of the distribution pipes. In this purpose are developed some calculation models and the effects of thermal agent temperature variation on the energy saving are illustrated by a numerical example.
Keywords: Central heating systems, Hydraulic unbalanced operation, Thermal comfort, Indoor temperature, Energy consumption, Low forward temperature, Energetical analysis, Energy saving, Computational models.
