1. 1. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Brianna Kilberg; [2020]
   Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

   Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE

3. 2. Modelling a Solar Driven Absorption Heat Pump

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Pierre-Antoine Gigos; [2016]
   Keywords : Absorption Heat Pump; Solar Cooling; EES Model;

   Abstract : Absorption Heat Pumps (AHP) have been developed since the late 19th century. They enable to produce cooling and heating directly from a heat source, unlike Compression Heat Pumps that require mechanical work. READ MORE

4. 3. Thermal energy recovery of low grade waste heat in hydrogenation process

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Sofia Hedström; [2014]
   Keywords : Low-grade waste heat; Waste heat recovery; Organic Rankine Cycle; Absorption Refrigeration; Aspen Plus; Steady-state simulations; Modeling and design;

   Abstract : The waste heat recovery technologies have become very relevant since many industrial plants continuously reject large amounts of thermal energy during normal operation which contributes to the increase of the production costs and also impacts the environment. The simulation programs used in industrial engineering enable development and optimization of the operational processes in a cost-effective way. READ MORE

5. 4. Experimental Investigation ofTwo-phase Flow in Microchannels“Co-current Absorption of Ammonia in Water to Design an Innovative Bubble Plate Absorber” : “Co-current Absorption of Ammonia in Water to Design an Innovative Bubble Plate Absorber”

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Ali Ammari; [2012]
   Keywords : Micro-channel; Ammonia-water; Two-phase; Absorption; Visual analysis;

   Abstract : For ammonia-water absorption refrigeration technology it is suggested to use bubble type absorbers because the higher contact surface area provides a higher mass transfer rate. Furthermore, dispersion of bubbles in the bulk of liquid phase also exhibits better heat transfer characteristics that facilitate the recovery of dissipated heat of the exothermic absorption.
