A review of the refrigeration system of one of the Centra supermarkets in Ireland led to the installation of the Danfoss ADAP-KOOL® combined with the Small Store System Manager. The energy savings amounted to 11% every year.
The good results of the refrigeration retrofit have encouraged Cross Refrigeration, who serves a lot of similar customers in Ireland, to recommend the turnkey refrigeration solution to other supermarkets.
“We can see many advantages for our many other supermarket customers of similar size and design, which can achieve significant and improved energy savings by targeting and applying this equipment to specific energy consumables within the store,” says Colin Singleton, Project Engineer from Cross Refrigeration.
The opportunities are far from exhausted and even better results can be achieved by extending the use of the Danfoss AK-PC pack controllers.
“Due to the fact that this was a retrofit into an existing system, the setup did not allow for full control of compressor operation, where most energy is consumed. Extended use of Danfoss AK-PC pack controllers would certainly have allowed even further savings through floating condensing temperature/pressure and suction pressure optimization, which can also be controlled and coordinated via the system manager,” says Shane Fleming, Danfoss Ireland.
