Solar absorption air conditioning. Degree thesis, Universiti Malaysia Sarawak (UNIMAS). (2005)
Abstract
The compression refrigerator system is one of the most conventional cooling systems for both offices and residential usage. However, this system leads to the high-energy consumption and the material it uses i.e. CFC, which believed, could impoverished the layer of ozone. Therefore, a study of a solar powered absorption system could be interesting. This project is aimed to investigate the process of the solar absorption air conditioning with LiBr-H2O by simple computer modeling using Matlab for education purpose. The conceptual modeling was done to determine energy, concentration of solution and steam, mass statement of each cycle. In the simulation process, the variation of coefficient of performance solar absorption air conditioning was determined in different temperature of one component with other components maintains as constant. The relationship between the COPs and temperature of components was analyzed and studied. The exergy study also had been conducted in this final year project study.
Pada masa kini, kebanyakan mesin hawa pendingin menggunakan teknologi pemanpatan di bidang pejabat dan rumah. Tetapi, teknologi ini memerlukan banyak tenaga eletrik untuk berfungsi, Selain itu, C.F.C. yang digunakan akan membocorkan ozon. Oleh itu, ahli sains mementingkan pemajuan teknologi penerapan mesin hawa dingin (Solar Absoprtion air conditioning) dengan tenaga solar. Dalam projek ini, mesin hawa pendingin dengan tenaga solar direka dan dikajikan. Semua persamaan mathematik yang diperlukan akan dicari dan diaturkan. Selepas itu, semua persamaan disusunaturkan ke dalam MATLAB untuk menghasilkan ‘simulation’. Dalam ‘simulation’, COP bagi mesin dicarikan dalam keadaan satu komponen mempunyai suhu yang berbeza, komponen lain mempunyai suhu yang tetap. Selepas itu, keputusan diambil dan dikaji. “Exergy” juga diambil dan dikajikan.
