Applications
Introduction
The objective of this application guide is to
provide an overview of which Danfoss Industrial
Refrigeration products are suitable for use in CO
2
applications.
Today, Danfoss is oering a broad programme of
industrial products applicable for CO
2
, however
this is dependent on demands regarding the
design pressure. The table on page 8 lists
the components which are suitable for CO
2
applications together with the maximum
working pressure limits.
General information about CO
2
For further background information about CO
2
as
a refrigerant, please refer to the Danfoss article
"CO
2
Refrigerant for Industrial Refrigeration".
There are a number of important factors to be
taken into consideration when determining the
design pressure.
1. Pressure during operation:
The pressure during operation is
dependent on actual system design
(single stage, cascade system or CO
2
-
”brine” system) and the load variation.
2. Pressure during “stand still”:
The pressure during stand still can be
very high and this has to be taken into
consideration:
• Asmallseparaterefrigerationsystem
can be used to keep the liquid
temperature at a level, where the
saturated pressure is lower than
the design pressure
• Designingthesystemwithanexpansion
vessel of a size that prevents the
pressure from exceeding the design
pressure.
• Designingtheplantsothatitcan
withstand the saturated pressure at the
design temperature (approx. 80 bar)
From Danfoss’ experience, it would appear
that the most common solution for industrial
refrigeration applications is to use a small
separate refrigeration system to limit the
temperature of the liquid CO
2
.
3. Pressure tolerances for safety valves
(10 – 15 %)
Safety valves require a certain pressure
dierence (dierence between set pressure
and reseating pressure) to ensure that the
valve is closed properly.
Normally the closing tolerance is 10%
of the set pressure. Additionally, it is good
practice to add 3-5% to the closing
tolerance, to take care of any pressure
variations / peaks.
Design pressure Note:
In the “IoR - Code of Practice” issued by
the Institute of Refrigeration in London, the
above mentioned tolerance is stated to be
20%
4. Temperature / pressure requrements for
defrosting
Depending on the actual design, dierent
ways of defrosting can be applied (natural,
water, electrical or CO
2
hot gas defrosting).
The CO
2
hot gas defrosting is the most
ecient, especially at low temperatures,
but it also has the highest pressure
demand. With a design pressure of
PS=50-52 bar, it is possible to reach a
defrosting temperature of approx. 9-10°C.
The saturated pressure at 9°C is 43.9 bar g.
By adding 10% for the safety valves and
approx. 5% for pressure peaks, the
requirement is for pressure PS ~ 50-52 bar g.
There is not one common method to perform
defrosting. All methods, as described above, are
used, depending on the system, but also on the
availability of suitable compressors and other
components.

Material compatibility
The tests have shown that CO
2
is dierent,
and modications have to be made on some
products. The large amount of CO
2
, which
can dissolve in polymers, has to be taken into
consideration. Some commonly used
polymers are not compatable with CO
2
, and
others require dierent xing methods e.g.
sealing materials.
When the pressure is close to the critical
pressure and the temperature is high, the impact
on polymers is much more extreme. However,
those conditions are not important for industrial
refrigeration as pressure and temperatures are
lower for these systems.
CO
2
is compatible with almost all common
metallic materials, unlike NH
3
. There are no
restrictions from a compatibility point of view,
when using copper or brass.
The compatibility of CO
2
and polymers is much
more complex. As CO
2
is a very inert and stable
substance, the chemical
reaction with polymers is not critical. The main
concern with CO
2
is the physiochemical eects,
such as permeation, swelling and the generation
of cavities and internal fractures. These eects are
connected with the solubility and diusivity of
CO
2
in the actual material.
Danfoss has carried out a number of tests to
ensure that components released for use with
CO
2
can withstand the impact of CO
2
in all
aspects.

Industrial Refrigeration Valves for CO
2
Applications
In NH
3
systems it is well known that there are
problems as a result of reaction with oil, oxygen,
water and solid contaminations, but these are all
handled today by frequent oil changes and use of
air purgers. Compared to NH
3
CO
2
is less sensitive,
but if water is present, problems may occur.
How can water penetrate into a CO
2
system?
• ThepressureofCO
2
systems is always above
the atmospheric pressure, therefore there are
not the same risks as in e.g. NH
3
systems, of
air/water penetration into a leaking CO
2
system. However, pemeation of water into the
system is still possible.
• WhenchargingCO
2
, there are dierent grades
of CO
2
, some of which allow relatively high
amounts of water.
• CO
2
is a safe refrigerant, and therefore there is
a risk, that it is handled without following the
normal refrigeration safety requirements. If a
system is opened up, air can penetrate into it,
and the moisture can condense inside the
tubes. If the system is not evacuated properly,
some water may well be retained.

Water solubility in liquid / vapour CO

From the reports, it seems that incomplete water
removal, due to insucient vacuum procedure, is
one of the main reasons for water contamination
in CO
2
systems. Vacuum procedures sucient for
ammonia systems are not sucient for CO
2
systems.
The acceptable amount of water in CO
2
systems
is much lower than in systems with other
common refrigerants. If the water content
exceeds the dew-point, and the temperature is
below 0°C, the water will freeze, creating a risk
of problems with equipment in the system e.g.
blocking control valves.
The water can very easily be removed by
mounting a drier in the system.
Driers in CO
2
are very ecient, and are normally
mounted in the liquid line to avoid any
unnecessary pressure drops being created.

In g. 2, the maximum water content, which can
be dissolved in the CO
2
gas phase, is compared
with other commonly used refrigerants. The
maximum water content for CO
2
is much lower
than for the other refrigerants. If the maximum
concentration is exceeded, this will appear as free
water or as ice in the refrigeration system.
An indication of water content can be obtained
by using a Danfoss SGN sight glass.

Due to the thermodynamic properties of CO
2
,
in particular the triple point, which is located at
much higher pressure than for all other common
refrigerants, the formation of solid CO
2
can occur.
If a safety valve is mounted in a CO
2
system at e.g.
52 bar, the pressure in the downstream (outlet)
line from the safety valve will pass the triple point
at 5.2 bar.
Below the triple point, CO
2
will change from a
mixture of liquid and vapour into a mixture of
solid and vapour.
The formation of solid CO
2
in the downstream
line can, in the worst case, block this line.
Safety valves in CO
2
systems
The most eective solution to this problem is to
mount the safety valve without an outlet line,
thus blowing directly into the atmosphere.
The phase change of the CO
2
does not take place
directly in the valve, but just after the valve, and
in this case in the atmosphere.
If safety valves or any other safety devices, have
to be mounted in liquid lines, they must never
blow to the atmosphere or any other places
where the backpressure is below 5.2 bar.
If the back-pressure is below the triple point (5.2 bar)
a very high fraction of the CO
2
will be solid.

Applications
Due to the high pressure dierence between
the condenser and evaporator, the Maximum
Opening Pressure Dierential (MOPD) demand
for the solenoid valve in some applications may
exceed the standard coil capabilities.
Typical applications could be:
Liquid injection for cooling the compressor
Hot gas defrost
Shut o valve before expansion valve
Therefore Danfoss oers a 20 W coil, that covers a
MOPD range up to 40 bar.
The 20 W coil program includes 24, 110 and 230 V
a.c. 50 Hz power supplies.
