Final Year Project (Week 7)

Week 7 

Implementation the Heating system on Simulink

Based on the equations and parameters' value that obtained last week, the Simulink model has been completed. It includes two basic level; the top level indicates the basic structure of the heating system, which consists with radiator and ASHP two subsystems. Meanwhile, the heating system is connected with the IDEAS model, in order to replace the original gas boiler heating system. Besides, the value of external temperature comes from a given data base and could be used directly. The schedule of the top level is shown below:

In details, the block diagram of radiator system is shown as figure below, the relationship is based on the equation of Treturn.

However, the relationship for the ASHP is more complicated than radiator because of a series of judgement of the value of required heat, in order to protect the heating system operated in a better efficiency as well as safety. The details of layout is shown below:

The model of the heating system has been completed, the next task is to testing its performance according to series of testing and simulation. A more complex task is to ensure its performance when connected with the IDEAS model. The reason is that all the components and value of IDEAS model, including the control system, are adjusted based on original gas boiler heating system. The task for me, is to design and modified it for the ASHP heating system.
