Author(s) : MARKUSSON C., JAGEMAR L., FAHLÉN P.

Summary

In order to utilize the energy saving potentials in variable flow systems understanding of heat transfer and the drive power of both liquid and air side is important. This paper discus control strategies and alternative system designs to minimize pump power in systems with cooling coils. A model of a cooling coil controlled by variable liquid flow rate is presented and validated by laboratory measurements. The air coil model is easy to use and have good applicability in modeling of systems of air-coils and can be used in control context for variable flow rate systems.
