Buildings contribute to 30% of global CO<sub>2</sub> emissions and consume 40% of the global energy supply (Yang et al., 2014). Heating and cooling requirements of the buildings form the major part of the energy consumption in buildings (Culha et al., 2015). Thus to solve this problem, one of the solutions currently being<br/>looked at is to...

The aim of this research thesis is to use machine learning models to distinguish owners of heat pumps from non-owners of heat pumps based on load profiles and temperature data only. As is the case with data mining project, its workflow can be divided into business understanding, data gathering, analysis, modeling and interpretation and...

In some countries, drying processes use up to 20% of the total energy consumption. Within the agriculture sector, drying of food and flowering products is a necessary step in production. A lot of companies make use of hot air dryers where the heat is gained by burning natural gas. A novel method is to use a heat pump assisted drying systems...

Energy consumption is still growing worldwide and due to the problems of global warming, sustainable developments become of more importance. Heat pumps are one of the technologies that can contribute to energy savings of industrial processes, for example by heat recovery from waste water streams. The focus of this research is to improve the...

The Dutch government set two environmental goals by 2050. One of them is being climate neutral and the other one is to have a circular economy. In order to meet both goals in the best environmental conditions, extensive environmental research is required. This thesis is one of these researches and its main focus is on the climate neutral goal by...

Photovoltaic Technologies in recent years have gained immense attention owing to reduced costs and increasing efficiencies. While decades of research in Photovoltaic Thermal (PVT) technologies, producing thermal and electrical energy simultaneously have brought these costs further down, improving a system’s overall performance. PVT collectors...

Heat pumps represent an effective technology to convert electrical energy to thermal energy through the expansion and compression of a refrigerant. Heat pumps are becoming increasingly more efficient<br/>which decreases energy consumption. However as heat pumps are getting increasingly more efficient, complexity is also increasing which leads to...

This thesis focuses on the combination of agent based modelling and Bayesian network. These techniques are used to see if this is a viable way of modelling green markets, like the heat pump market. These markets can change quickly. The combination of the techniques gives the investors in the model the ability to learn from new information during...

Electricity is a basic need in today`s society, being present in almost every aspect of life. The extensive infrastructure that transports electricity to the consumers, is expected to always work. At the same time there is a growing realism that the energy sector needs to modernise and ‘greenify’, in order to become more climate friendly. This...

This research is about the spatial integration of a self-sufficient renewable energy system in selected urban blocks in the neighbourhood Ramplaankwartier in Haarlem, providing the heat demand of the residential buildings located in these selected urban blocks. Solar energy production and thermal energy storage are the selected energy production...

Because the earth loses her heat less efficient, the average global temperature rises. As a result, more extreme weather conditions occur. In urban environments, rain during these extreme weather conditions cannot be discharged immediately. A Polder Roof, a combination of a blue and green roof, provides a solution for this problem. This roof...

The growth of electricity generated by renewables increases the intermittency of the Dutch electricity production. To deal with this, the Dutch power system requires a higher amount of flexibility in the future. Demand response with heat pumps is one of the options with a high potential to provide flexibility, because it offers the potential to...

The energy consumption in the industry field is considerable. Saving energy has great potential in many industrial processes. For example, heat recovery from the spent cooling water can be achieved by applying heat pump technology, and the recovered heat can be used for district heating. Previous study indicates that the compression-resorption...

Waste heat recovery is essential to reduce energy consumption in industry. A heat pump can be used to upgrade waste heat to a temperature level that is suitable for process heat. This study concerns a compression-resorption heat pump. The goal is to optimise the heat pump energetically, while keeping the investment attractive. Entropy production...

The last step in the production of milk powder is drying, a very energy intensive process that demands 30% to 40% of the total energy input of a typical plant. It takes place in Spray Dryers (SD), where concentrated milk is sprayed and placed in direct contact with hot and dry air that cools down and gains humidity as water is evaporated from...

A Compressor Resorption Heat Pump (CRHP) is a potential contribution to energy reduction in applications in which waste streams are upgraded, with limited energy addition, into high value process streams for reuse in industry. Previous research concluded that a CRHP with a wet screw compressor is a suitable option for many applications. An...
