Data for Optimal passage size for solar collector microchannel and tube-on-plate absorbers
Listed in figshare
Solar thermal collectors for buildings use a heat transfer fluid passing through heat exchange channels in the absorber.
Description
Flat plate absorbers may pass the fluid through a tube bonded to a thermally conducting plate or achieve lower thermal resistance and pressure drop by using a flooded panel or microchannel design. The pressure drop should be low to minimise power input to the circulating pump.
A method is presented for choosing the optimum channel hydraulic diameter subject to geometric similarity and pumping power constraints; this is an important preliminary design choice for any solar collector designer. The choice of pumping power is also illustrated in terms of relative energy source costs. Both microchannel and serpentine tube systems have an optimum passage diameter, albeit for different reasons.

Double-pass and flooded panel designs are considered as special microchannel cases. To maintain efficiency, the pumping power per unit area must rise as the passage length increases. Beyond the optimum pumping power the rise in operating cost outweighs the increase in collector efficiency.<br><br>This code runs in Matlab r2017a.Typically a script file will either produce a single figure or is designed to be run in sections, producing one graph after another.
The function files are almost always called by script files
