Manage the Balance
Between Main Parameters


Low GWP
To optimize only one parameter in the
triangle will not bring us closer to the
goal of sustainability


Safety
Balancing parameters with respect to
sustainability and making long-term
planning settled in global agreements
Specification
– That will create sustainable results -

Refrigeration & A/C Controls
The purchase cost of a product is
important
Legislation Lever

The LCC (Life Cycle Cost) is
increasingly more important - for
individuals and society

What matters is the technology giving
the LLCC (lowest LCC)
Energy Efficiency is the major
contributor to improve LLCC

The Danish Crown Slaughter house approach
Refrigeration & A/C Controls
•
Rethinking – Re-engineering
•
After assessing processes and
practices and an energyefficient ammonia cooling
plant, the Danish crown cut
energy consumption by 30%.
•
A joint effort pays off by
developing a range of tools for
energy conscious planning
