| Planning / Implementation / Main components | compressor
from Bock Kältemaschinen GmbH in refrigeration systems for the food sector
| | Refrigerant | carbon
dioxide (CO2) | | System
start-up | first
plant in 1993 | | The
trend towards natural refrigerants has arrived in the industrial sector - and
particularly in the food sector. Years ago, innovative system developers called
on Bock to develop a series of compressors for use with carbon dioxide, in addition
to its standard compressors and compressor series for ammonia. | | Demands | Reduce
energy consumption while increasing the freezing speed of shock-freeze plants
in the food sector, thereby improving product quality. Ensure temperatures of
-40°C to -50°C in the shock-freeze room. | | Solution | Refrigeration
system in cascade arrangement with carbon dioxide used as the refrigerant in the
low-pressure stage. |
|
Technical specifications:| Type
of facility | cascade
circuit, direct evaporation,
dry expansion | | Refrigerant | CO2
in the low-pressure stage | | Refrigerating
capacity | various
capacity sizes, up to approx. 500 kW at an evaporation temperature of -50 °C
(parallel cascade arrangement) | | Special
features / Comments | To
date, more than 30 plants using this technology have been installed and taken
up into operation in Germany. |
