The domestic use of natural gas for heating is the prevalent option in the Netherlands. However, heat pumps will be mandatory in most Dutch households by 2026. Therefore, insights are needed in how citizens perceive this technology, by taking into account various societal, technological, economic, environmental, …

Understanding sludge rheology and optimizing equipment performance is crucial for energy efficiency in wastewater treatment plants (WWTPs). This study examined sludge rheology after thermal hydrolysis pretreatment (THP) at 60, 80, and 120 ◦C for 2 h, followed by anaerobic digestion (AD) at 37 ◦C for …

Heat pumps are a promising option to decarbonize the industrial sector. However, their performance at a plant-level can be affected by other process changes. In this work, process changes that improve the heat pump's performance have been identified using Process Change Analysis (PCA), where the background …

Steam generating heat pumps show great potential for reducing carbon emissions in the industrial sector. However, predicting their performance is challenging as the exergy destruction of e.g., compressors and expansion valves increases with the temperature lift and condenser temperature. With over seventy …

Het project “In twee stappen naar een aardgasvrije en comfortabele Nederlandse woonomgeving” ontwikkelt een manier om de overstap naar aardgasvrije woningverwarming eenvoudiger, minder spannend, betrouwbaarder en beter te maken. Dat doen we door een “hybride” tussenstap, die een behoorlijke aardgasreductie …

A prototype of an indoor monoblock heat pump was tested at multiple ambient temperatures, to determine heat output, COP and the impact of defrosting events. Component efficiencies and the ice accumulation process were analysed. Options to improve performance were suggested.
