The design of a heat recovery system on greywater in the kitchen context

This project aims to create a proof of concept to evaluate the potential value of implementing a heat recovery system for Quooker in the kitchen context. In response to the global goal of achieving net-zero CO2 emissions by 2050, reducing energy loss has become a shared priority. Heat recovery systems can significantly decrease energy...

Sensitivity study on a Reverse turbo-Brayton cryocooler for zero boil-off on an airborne liquid hydrogen tank

Liquid hydrogen has been identified as a low-emission alternative to hydrocarbon fuel sources for aircraft. Although there has been a notable increase in the number of studies and technology readiness of liquid hydrogen technologies in the recent decade, there is still more research and development necessary to realize commercially viable...

Enhancing Energy Efficiency and Sustainability in Healthcare: Implementing a Heat Exchanger for Carbon Footprint Reduction

This paper addresses the urgent need to optimize the GreenCycl facilities energy utilization, by harnessing heat from the effluent of three thermal washing-disinfection machines into the preheating of cold clean water. Currently for every washing-disinfection cleaning program, 60 times a week, 105 liters of water with a temperature of 60 \degree...

Optimisation of a latent heat storage system containing a salt hydrate

Design & Validation of a 3D-printed Heat Exchanger Manifold

Metal additive manufacturing has enabled great diversity and design freedom in heat exchanger design. However, these benefits cannot be adequately realised without optimizing its ancillary components as well, specifically the inlet and outlet manifolds. Optimizing the manifolds can significantly improve the flow distribution inside the heat...

Preliminary design methods for the thermal management of fuel cell powered aeroengines

Hydrogen fuel cells are set to play an important role in decarbonizing the aviation sector. They operate at higher efficiencies than turbine engines, but their low operating temperature requires a dedicated thermal management system. The added drag, weight and parasitic power of such a system has a high impact on aircraft performance and its...

Design of a Heat Exchanger with Thermal Storage using PCM

Energy efficiency is a key goal for the Quooker system. To further increase the energy efficiency of the Quooker system, this study investigates a possible heat integration system where the waste heat from the refrigeration cycle for chilled drinking water is implemented to preheat water before entering the boiling water reservoir.<br/>Due to...

Evaluation on the Effect of Buoyancy on the flow, heat transfer and performance of a Printed Circuit Heat Exchanger A Numerical Study

One of the biggest threats that humanity is currently facing is the climate change. The amount of greenhouse gases emissions and specifically the amount of CO2 in the atmosphere has increased and is projected to increase even more in the next years. One possible solution is the use of supercritical CO2 as an alternative working fluid in power...
