Due to financial and environmental benefits, the interest in high-temperature heat pumps, producing heat sinks above 100 °C, is rising. Research is intensifying, and technology is developing fast. However, of all the components of the heat pump cycle, the oil management system seems to be the least investigated, even though 12% of the faults in...

To face the ongoing climate crisis, the Dutch government adopted a number of policies and measures to limit its greenhouse gas emissions. It is estimated that 10% of Dutch annual emissions are caused by the built environment, a large portion of which come from two sources: space heating and domestic hot water.<br/>The use of heat pumps is said...

Industrial processes are estimated to be responsible for about 20 % of the total greenhouse gas emissions within the European Union (EU). The majority of the industrial energy demand is related to the thermal energy required for process heating. Thus, there is a need to make radical changes to the industrial heating supply to achieve net-zero...

The heating and cooling sector is one of the biggest sectors at this moment due to drastic fluctuations in climate parameters. Even though this sector helps in making sure everyone gets comfortable temperatures at the home, office, etc., there are environmental consequences attached to them. These consequences are in terms of emissions of...

European and Dutch environmental goals prescribe that national emitted CO2 levels need to be reduced. Therefore, the Dutch government chose to transition the whole Dutch residential sector to gas-free living by 2050, to decrease CO2 levels. Homeowners are responsible themselves for adopting a sustainable heating system, where specifically heat...

By placing multiple Peltier elements in a linear arrangement while two water flows run past the elements, a temperature increase can be realised in one flow while the other flow is cooled down. In this study the heating of domestic hot water with Peltier elements as solid state heat pumps, and a heating network was investigated. A numerical...

The amount of Heat pumps in the Netherlands is on the rise mainly because of the climate accords that hope to abolish the use of natural gas. This project aims to improve upon the current design of heat pumps to answer to this increased market. This is done in collaboration with ThuisBaas and more specifically Errico Garofalo who created the...

Power-to-X (PtX) technologies are accelerating the energy transition. Increasingly, these technologies are also being leveraged as flexible energy resources to support the electrical grid. PtX models are often represented using a constant efficiency term as a linear relation between the power input and energy output. However, the operational...

This paper focuses on the control of microgrids where both gas and electricity are provided to the final customer, i.e., multi-carrier microgrids. Hence, these microgrids include thermal and electrical loads, renewable energy sources, energy storage systems, heat pumps, and combined heat and power units. The parameters characterizing the...

The impact of size and working fluid on the efficiency, operating range, and axial thrust on bearings is examined for high-speed, oil-free centrifugal compressors. First, the development and validation of a reduced-order model based on scaling principles is documented. Then, the validated compressor model is used to generate design maps for...

Geothermal energy (GE), as an ideal renewable resource for building cooling/heating with stability and abundance in energy supply, has been widely exploited in developing countries. The common utilization forms of GE mainly include the ground source heat pump (GSHP), underground duct system (UDS), and abandoned wells energy (AWE) system....

An integrated energy system consisted of PV panels, EV (electric vehicle), BES (battery energy storage), and a HP (heat pump) coupled with thermal storage tanks (TES) has been studied. The research aimed to minimize the total energy costs by scheduling the optimal power consumption of each device as response to two external signals as part of a...

Achieving energy efficiency in the built environment requires extensive efforts in the renovation and adaptation of housing stock. A promising design solution is the heat pump. While gas boiler systems are commonly used in Dutch non-profit housing stock, the share of dwellings with a heat pump grew from 1.6% in 2017 to 3.2% in 2021. However,...

By the year 2050, the Dutch government aims to have transitioned away from natural gas and provide heating to all residential dwellings using more sustainable technologies. Heat pumps (both all-electric and hybrid models) are expected to play a large role in fulfilling this heating demand. However, because heat pumps require electricity in order...

Industrial decarbonisation has largely stagnated over the last years in Germany. A large share of Greenhouse Gas (GHG) emissions stem from the combustion of natural gas for producing higher temperature process heat. High-Temperature Heat Pumps (HTHPs) are an emerging technology that can upgrade waste heat with electrical input to high...

In order to reach the goals of the Paris Agreement, global emissions must decrease at a high rate. Looking at the industrial sector, the largest share of energy is used for process heating, with fossil fuels as its primary source. A way to improve the energy efficiency and reduce the emissions of process heating is by the integration of heat...
