Ice slurry pilot and demonstration system for food refrigeration in supermarkets.

The idea of the system is to perform a medium step between the laboratory systems of the EUREKA project FIFE (Fine-crystalline Ice: Fundamentals and Engineering), which are operated with success, and lower-cost systems, designed for practical applications. The refrigeration machine, with a cooling power of 15.5 kW, is running with ammonia and is connected to an ice generator of the mechanical scraper type. A storage tank of 1.5 m3 with a mixing device was installed. In the primary and secondary circuits, displacement pumps are transporting the ice slurry to the consumers, which are a cold-storage chamber, two different cooling cabinets for milk and meat products and a transportable cooling display cabinet.
