Aims

The aims of the course are to:

• To critically assess the value of heat pump technology as a way of reducing emissions of CO2.
• To design an experiment to measure the performance of the heat pump, and to make measurements which allow its performance to be modelled.
• To produce a model of the heat pump which is validated against the experimental measurements.

Content

This project looks at the performance of a commercially available heat pump for domestic heating applications. Students will be required to designb and perform an experiment to measure the performance of the heat pump, and build a model of the heat pump. This model will be used to explore the CO2 saving which could be made by using heat pumps in a domestic heating application. Students will work in groups of 4 to design and perform the experiment. Individual tasks may be distributed amongst group members as decided by the group. Individual reports are required from group members, as well as group reports.

Week 1

Familiarisation with the equipment. Construction of a simple python model of the heat pump. Design of the experiment. First interim (group) report and review meeting (20%).

Week 2

As a group, refine experimental plan, adjust logging software and make measurements on the performance of the heat pump using an external water circuit. Individually: finish writing simple python model of a heat pump and prepare an individual report thereon (20%).

Week 3

Complete experimental work, including measurements on the internal (refrigeration) circuit. Make comparisons with the python model.

Week 4

Measurements of availability loss within the heat pump and refinement / extension of python model. Assessment of carbon saving. Final individual report (60%) with up to one third of the report (20% overall) devoted to group activity.

Aims

The aims of the course are to:

• To introduce you to the basic principles of heat exchanger design.
• To compare predicted with actual performance and hence understand the limitations of heat transfer correlations.
• To give you experience in the production of workshop drawings and the problems of manufacture and assembly to such drawings.
• To demonstrate that different 'optimal' designs can arise from the same brief.

Content

Heat exchangers are found virtually everywhere, from domestic heaters to exotic space applications. This project involves the design, construction and testing of a small shell-and-tube heat exchanger. It spans the whole process of product development, from the conception and sizing using basic theory, to the manufacturing, assembly, and final testing.

Students will work in groups of two to undetake the initial design. The groups will then be paired, into groups of four who will then finalise the choice of design. The interim report will describe both the initial pairs design and the final group of fours design. The interim report will include the theory and drawings and carries a large proportion of the total marks.

This project is front loaded. Weeks 1 and 2 require a lot of work. Weeks 3 and 4 are light.

Week 1

At the start of the project you will learn about the fundamentals of heat exchangers, using a poorly-designed heat exchanger as an example in the mini-lecture. You will develop your own computer-based design tool, which you will use to select an optimal configuration. The majority of groups use Python, although some have used Excel and Matlab, prior experience is helpful here.

Week 2

In the second week, you will refine your design in line with the workshop's manufacturing capabilities and your assembly capabilities. Clever engineering at this stage can greatly simplify assembly and improve off-design performance. At the end of the week you will produce detailed manufacturing drawings and an interim report.

Week 3

In the third week you will work out the off-design performance of your heat exchanger and use your computer-based design tool to assess other groups' designs. This feeds into your final reports. Meanwhile, the workshops will be machining parts to your manufacturing drawings and giving feedback on your designs.

Week 4

In the final week you will assemble your heat exchangers. On test day, all groups test their heat exchangers together. The project finishes with a comparison of all heat exchangers and a glamorous prize ceremony.
