Abstract

In this paper we present a model of the dynamics of a two-heat-exchanger network connected in parallel. The model is represented using the inner admittances, which represent the dynamics of each heat exchanger, in series. The series connection of the inner admittances indicates the complexity of the two-heat-exchanger network. The complexity mainly depends on the characteristic of the confluent process. The fluid temperature behavior in the pipe between the heat exchangers and the confluent junction markedly influences the characteristic of the confluent process. We investigate the dynamics of the two-heat-exchanger network with respect to the effect of the piping and the confluence.
