Investigating the dynamic mode of a heating system operation
Summary
Main specifications of the hydraulic mode of the advanced heating systems are given. The standard hydraulic calculation does not provide for the complete amount of information on the heating system operation. Accordingly a mathematic instrument (software-model) was developed to calculate a hydraulic circuit of an advanced heating system in a transit mode of operation. Hydraulic calculations of the two heating systems of similar structure, however, equipped with different balancing fittings were carried out. Typical tendencies of the system active elements operation were analyzed. Recommendations on specific use of the control valves were formulated.
Key words
flow rate , pressure drop , hydraulic condition , heating system , resistance characteristic , thermostatic control valve , balancing valve
