CO2 commercial refrigeration system in Jordan.
Number: pap. n. 1044
Author(s) : ABDIN N., HAFNER A., GIROTTO S., et al.
Summary
According to IPCC/TEAP the annual refrigerant leaks from commercial refrigeration units related to the total charge are between 15 and 20 % in Europe and ~30 % outside Europe. Phasing out the current H(C)FC systems in the near future with energy efficient systems applying natural working fluids would result in a significant reduction of the environmental impact of commercial refrigeration. Currently the main barrier for introducing low-GWP alternatives, especially carbon dioxide (CO2 / R744) in the supermarket sector outside of Europe, is the lack of knowledge and experience that these systems actually can perform even better than state of the art HFC technology. Another barrier is the limited availability of equipment in these regions.
Through a CCAC-funded project, implemented by UNIDO, the first transcritical CO2 unit is implemented in so-called HAT (high ambient temperature) country. The supermarket is located in the capital city of Jordan, Amman. Commissioning of the unit took place in early 2018. The unit is equipped with a data acquisition system.
The work will briefly describe the different parts of the CO2 unit and the display cabinets. Initial measurement results and performance analysis indicate a significant improvement of the energy efficiency, compared to the previous R22 units.
