Type of article: Article, IJR article

Summary

A vapour compression cycle with a solution circuit and desorber/absorber heat exchange was investigated experimentally using the ammonia-water mixture. A breadboard heat pump was designed and built to measure the cycle performance. The cooling capacities were between 7 and 12 kilowatts, which increased with an increase of the ammonia concentration. The pressure ratios encountered were in the range of 2-6. A COP of 1.44 at the temperature lift of 79 deg C was recorded with a cooling capacity at 10.25 kilowatts. The experimental results are compared to that of the single-sage and two-stage cycle. The experimental results showed that the COP varied in the range of 1-2%, while the temperature lift increased by the range between 0 and 6 deg C. In addition, the analysis of the test result uncertainties was made.
