The Efficiency of Temporary Settlements
Another positive outcome of this investigation is
that this refrigerator can also be used for medical
use as well such as to store vaccines. In a case like
Glastonbury Music Festival, keeping medical
equipment and vaccines refrigerated is quite vital
and hence with further study, this design would be
beneficial to users in many ways.
The ultimate aim is somehow achieved with the presentation of the 3D model of the
Solar Absorption Refrigerator Concept. It has been sized down compared with the
models which are very similar in the market. However, one of the desired goals was to
calculate the sizes of each component involved in the absorption refrigeration cycle
such as the condenser, absorber, pump and generator etc. This was not achieved but
the sizes of the components were assumed as advised by the supervisor as the main
focus is on making the system portable and energy efficient. Also the solar panel
designed is also slightly larger compared with the refrigerator, however this still is an
‘acceptable’ size for temporary applications. Since size was a primary concern in the
aim of the project, with the 3D model it can be demonstrated that this goal is achieved
with room for improvements.
This project looks at how solar energy
and solar radiation can be harvested to
produce electricity and heat to power a
refrigerating system that is to be used for
Glastonbury Music festival which last for
five days. Because of the invention of the
renewable source into the system, the
carbon emission is reduced hence
environmental damage is reduced; the
use of solar energy in the proposed
system eliminates the need of a power
grid system. This was part of the desired
goal and is achieved.
Project summary
Investigation of energy efficient solar absorption
system with the case of Glastonbury Music Festival
Project Objectives
This investigation includes analysis of solar
collectors, in-depth study of vapour
absorption refrigeration process and the
components involved in the proposed design
and analysis of efficiency of the proposed
concept. A 3D model of the proposed design
is also developed.
Project Conclusion
The ultimate aim is achieved with the presentation of
the 3D model of the Solar Absorption Refrigerator
Concept. It has been sized down compared with the
models which are very similar in the market.
