Number: pap. 1105

Author(s) : FREDSLUND K, KRIEZI E. E., MADSEN K. B., et al.

Summary

There are selective pioneer supermarket installations with CO2 racks equipped with ejector technology in various locations mainly in Europe. A Multi Ejector Block consisting of a range of ejectors installed in the rack functions as an expansion recovery module. Climate, size of supermarket and design varies among the applications. The paper will focus on the different systems and configuration and the expectation in terms of energy saving. The impact of the design parameters on the functionality of the ejector, the capacity control and the system performance will be investigated. Data from the field installation will be presented and discussed. Energy savings from 4-15% have been seen.
