Waste-heat recovery estimation on ships by means of Conditionally-Gaussian Filtering

:This paper presents the waste-heat energy recovery estimation of a cooling network on cruising ships. Based on first principle modelling and a known circuit layout the waste-heat recovery system is presented as a partially-observed system, whose unknown states and parameters can be estimated online by application of Conditionally Gaussian filtering. Accurate estimates and input-output behaviour of the circuit are obtained, which has been validated against a set of real data provided by the ship operator confirming the efficiency of the algorithm.
