System start-up |
1992 |
A Swedish slaughterhouse operates numerous refrigeration and freezing rooms for producing and storing its sausage and meat products. Its ammonia-based refrigeration plant was built by Alfa Laval. |
|
Demands |
The slaughterhouse was looking for an efficient, environmentally friendly solution for its various refrigeration and deep-freezing needs. |
Solution |
The engineering firm designed an economical ammonia system with a refrigeration output of 4,000 kW. As the ammonia cools the production and storage rooms, a temperature of approx. 70°C is generated on the heat producing side. This waste heat is used by desuperheaters, liquefiers and heat pumps to warm up heating-circuit and service water up to 67°C in several steps. The 800-kW heat pumps are connected directly to the refrigeration cycle with ammonia plate heat exchangers, thereby additionally enhancing the system’s efficiency. |
