Summary: The fouling of exhaust heat exchangers caused by the deposition of soot particles reduces the heat transfer efficiency in waste heat recovery systems. In this study, a deposition performance experimental system and an improved CFD-based soot deposition prediction model were proposed to investigate the deposition characteristics on tube banks in exhaust heat exchangers. The experimental or numerical investigation showed that the comprehensive performance of the tube bank deteriorates by about 0.45%-1.85% after 4 hours of soot deposition, and the tube bank with smaller tube spacing has lower deposition amount.

Summary: According to the IPCC 5th Assessment report, energy-efficient appliances can reduce global electricity consumption, despite an expected increase in the number and ownership of appliances. The IEA expects a significant improvement in energy efficiency for traditional appliances and an increase in the number of new appliances installed. Research on energy-efficient appliances is growing in developed regions (North America and Europe) and developing regions, particularly in Asia Pacific with a focus on China and India. Policies are usually implemented before the core research on the topic, but this trend seems to be changing for new appliances, with research occurring shortly after or in parallel with policy establishment.

Summary: To reduce dependence on fossil fuels in residential areas, low-carbon-footprint technologies like heat pumps should be used. This study utilizes a low-global-warming-potential refrigerant in a reversible heat pump system, which is supported by a thermal storage tank, photovoltaic installation, and battery storage system with a dedicated control strategy. The performance of the reversible heat pump in three European climates is analyzed through simulations, demonstrating its ability to meet summer cooling demand and heating demand with backup sources. Economic analysis shows that the inclusion of a battery storage system increases overall flexibility and self-sufficiency, although it results in longer payback times compared to reference energy systems.
