EnergyPlus Simulation of Single-Coil Twin-Fan Air Conditioning System
… energy performance of the newly-developed Single-Coil Twin-Fan (SCTF) air conditioning system. The objectives of this project were to develop a customized module of the energy efficient SCTF system, validate the model using industry-accepted simulation verification methods, and implement the …

Laminar-flow Liquid-to-air Heat Exchangers - Energy-efficient Display Cabinet Applications
… systems being converted to systems with indirect cooling by means of a liquid secondary refrigerant. The cooling coil is an important component in a display cabinet and traditionally, different kinds of tube-coils, with aluminium fins on expanded circular copper tubes, have been used. Many …

Control strategies for exothermic batch and fed-batch processes A sub-optimal strategy is developed which combines fast response with a chosen control signal safety margin. Design procedures are described and results compared with conventional control.
… thermal runaway whilst keeping some spare cooling capacity to ensure that operation at constraints are not violated. A special feature of the method proposed is that switching temperatures and temperature profiles can be readily found from plant trials whilst the addition rate profile Is …

Heat pipe dehumidification for supermarket energy savings
… to reduced frost buildup on the refrigeration coils. Chapter two includes a physical and psychometric analysis of the heat pipe, proving that for any system where direct evaporation dehumidification is used, at any given time when dehumidification is being performed, the addition of a heat pipe …

Dynamic modeling and global optimal operation of multizone variable air volume HVAC systems
… of fan, air distribution system, zone(s), cooling coil and primary plant (chiller) as one multivariable nonlinear system in a way that is useful for control analysis. Using the bottom-up approach a large-scale VAV system model has been developed. This model considers the interactions …
