Abstract

Nowadays absorption chiller systems, because of their advantages, have been very privileged. In comparison with other HVAC&R systems one the most advantages of these systems is the possibility of consuming low cost energy sources such as natural gas or gasoline to decrease the system running costs. Also, renewable energy sources can be used instead of fossil fuels with these systems. Solar energy, as one of the most accessible and suitable clean energy sources, has a lot of potentiality in using with absorption systems. In addition, since the peak of air conditioning and cooling demands are in the same phase with the peak of solar radiation, investigation of the different potentiality of solar energy utilization in cooling systems is very important. Utilization of ground source, as one of the other clean and accessible energy sources, can be very useful. Using this source as an energy reserve or supply source, depend on its deployment, can be very beneficial. In this research firstly the absorption chiller systems, their working cycle and different kind of these systems are being described in brief. After that some of the research in the area of using renewable energy sources such as solar and ground source energy in absorption systems are being reviewed.
