An important |
|||
contribution can |
|||
be made by using |
|||
natural refrigerants |
|||
such as R723, |

which is particularly |
|||
environment-friendly |

with an ODP of 0 and |

a GWP of 8. |

says Kaltenbrunner. Its low acquisition |
|||
costs, along with being future-proof and |
|||
reliable, make the natural refrigerant |
|||
a popular choice for planners and |
|||
operators of refrigerating systems. |

An environmentally friendly add-on for existing systems |
|||
These aspects were also in the focus of |
|||
a project undertaken by eurammon |
|||
member Th. WITT Kältemaschinenfabrik |
|||
GmbH for Herrmannsdorfer |
|||
Landwerkstätten, a food-producing |
|||
company. The family-owned business |
|||
from Bavaria doesn’ t only set great store |
|||
by organic farming and food processing, |
|||
but makes a point of pursuing a holistic |
|||
sustainable subsistence strategy. This |
|||
is why the company, when planning |
|||
a new refrigerating system, looked |
|||
into environment-friendly alternatives |
|||
that were not only durable and |
|||
energy-efficient, but also used natural |
|||
refrigerants. The idea was for a new |
|||
cooling system to add to the capacity of |
|||
the existing one, an ammonia-operated |
|||
chilled-water system. Herrmannsdorfer |
|||
Landwerkstätten also wanted their system |
|||
to be reliable, safe, and easy to maintain. |
|||
Against this background, Th. WITT installed |
|||
a chilled-brine compact refrigeration unit, |
|||
tailor-made for the specific requirements, |
|||
charged with 20kg of the natural |
|||
refrigerant ammonia dimethyl ether. Using |
|||
two reciprocating piston compressors, |
