Presentation No 1058 – Development of vapor compression system using natural refrigerant – 14th IEA Heat Pump Conference, Chicago, USA

---

Recently, as the life quality has been improved, the demand for the refrigeration system has been increased
rapidly. Also, the interest in low GWP chiller is increasing, due to the important environmental problem. Here,
we have developed a refrigeration system using R-718 refrigerant, water. Considering the large specific
volume and surface tension of the water, we have designed heat exchangers and the compressors. We introduce
the performance of the new system with the manufacturing process of the system. Moreover, we show the
preparation procedures of the test that are necessary for the system operation.
