The very top management of Novo Nordisk is focused on global warming as an important<br />
problem and therefore it has been decided to avoid the use of HFC refrigerants. The<br />
Global Warming Potential (GWP) values below used are the 20 year integration times<br />
as seen in a declaration.<br />

Results<br />
Johnson Controls has built and supplied the customer an ammonia chiller for cooling<br />
propylene glycol that in turn cools a cold room for storage of ready for sale products.<br />
The supplied unit is one of the biggest in this capacity range from about 45 kW to 160<br />
kW. The design results in a minimal foot print for the unit. The low charge of the system<br />
is attractive in places where an unexpected release of refrigerant can cause problems<br />
with neighbours.<br />
The customer Nordlaks AS is very happy with the performance of the system.<br />

Ammonia chillers are used in many places but the GWP is 0 and is therefore not<br />
reported in the table above.
