Simulation on hydraulic heating system of building under the control of thermostat radiator valves

Considering the dynamic control process of thermostatic radiator valves (TRVs) and adjustement behavior of consumers, as well as heat transfer through neighborhood, the main purpose of this paper is to derive a total model for simulating and analyzing the dynamic behavior of hydraulic heating system with the control of TRVs in multi-family building, based on state space model of room dynamic performance. This is done by treating building and the heating system as complete entities. First of all the dynamic models for rooms, radiators and TRVs are derived.
