It is well known that the energy consumption of refrigerating and air-
conditioning units is as high as heating systems. It is also clear tha
t cooling loads and availability of solar radiation are approximately
in phase. Turkey is located in an ideal position to benefit from solar
energy for not only water-heating but also cooling. The use of solar
powered absorption refrigerating and air-conditioning systems will sav
e energy, especially in the summer season. The contribution of these s
ystems to the Turkish energy sector and, consequently, to the economy
will be considerably high. In this study, a combined water-heating and
cooling system based on absorption refrigeration was designed and con
structed. The system consists of four flat plate collectors, an evapor
ator, an absorber, a generator, a condenser, a solution pump and two h
eat exchangers. Each part was custom designed to provide 4000 kcal/h c
ooling load. In this system, a mixture of R22 and DMETEG (DiMethyl Eth
er Tetra Ethylene Glycol) is used as the working fluid. The R22, which
has a less damaging effect on the ozone layer compared to other CFCs,
was employed as refrigerant. The thermodynamic results of the experim
ental system were compared with theoretical calculations, and a reason
ably good agreement was found. The results show that the present syste
m is efficient and effective.
