Natural Refrigerant Grade Liquid Anhydrous Ammonia NH3 R717 99.98%
In 1876, Carl Von Linde first used ammonia as a refrigeration
system. Many countries in Europe have stopped the use of HCFC refrigerants,
and new refrigerants, as well as well-tried and trusted
refrigerants like Ammonia and Carbon Dioxide, are being considered
for various new applications as well. R717 refrigerant grade ammonia will become the main refrigerant of
industrial refrigeration equipment.
2. Advantages of R717 Liquid Anhydrous Ammonia
1>Energy efficiency - Typically a flooded ammonia system would
be 15-20 % more efficient than a DX R404A counterpart.
2>Environment - it has both GWP (Global Warming Potential) and
ODP (Ozone Depletion Potential) equal to zero
3>Safety - At the same time, unlike most other refrigerants, it
has a characteristic odor that can be detected by humans even at
very low concentrations.
4>Smaller pipe sizes - In both vapor and liquid phase ammonia
requires smaller pipe diameters than most chemical refrigerants.
5>Better heat transfer - Ammonia has better heat transfer
properties than most of the chemical refrigerants and therefore
allow for the use of equipment with a smaller heat transfer area.
6> Refrigerant price - In many countries the cost of ammonia
(per kg) is considerably lower than the cost of HFCs. This
advantage is even multiplied by the fact that ammonia has a lower
density in the liquid phase. Furthermore as any leakage of ammonia
will be detected very quickly due to the odour, hence any potential
loss of refrigerant will also be lower.
3. Applications for R717 Liquid Anhydrous Ammonia
Since refrigerant grade ammonia has many advantages and
characteristics. Natural refrigerants R717 ammonia is generally
applicable to large and medium-sized refrigeration, industrial
refrigeration, ice making, artificial ice and indirect central air
conditioning. The fluorine refrigeration system is generally
applicable to refrigerators, freezers, display cabinets, household
air conditioners, commercial air conditioners, small and
medium-sized cold storage and refrigeration, low-temperature air
conditioning in factories, air conditioning, ice cream, cold
drinks, ice, artificial ice fields, and small industrial
4. Toxicity and flammability
Ammonia has a strong toxicity and flammability. If the volume
meter, when the content of ammonia in the air reaches 0.5% ~ 0.6%,
in which people stay for half an hour can be poisoning, 11% ~ 13%
can ignite, reaches 16% flame would explode. Therefore, the ammonia
refrigeration machine room must pay attention to ventilation and
exhaust, and the air and other non-condensable gases in the system
must be eliminated frequently.
5. Quality control (impurity gas and heavy metals)
Water vapor is the most important impurities in ammonia
refrigeration system. It not only corrodes the refrigeration system
but also changes the vapor pressure of the refrigeration system,
making the refrigeration system less efficient. Other impurities
such as oil, hydrocarbons, H20, 02, Ar, N2, H2, CO and CO2 will
also affect the refrigeration system.
Our factory to produce Refrigerant grade Ammonia GasR717 introduced
advanced EGPS Ammonia purification system. It will mainly
pressurized ammonia into activated carbon filter, the main impurity
removing oil and organic gases, then into the solid particles in
the dust filter to remove ammonia, and then into the electric
heating carburetor to ensure the operation of the system with
constant pressure, then into the low boiling point in the ammonia
distillation tower to remove ammonia gas, then through the relief
into the oxygen in the dryer to remove ammonia trace water, finally
enter the buffer tank storage for users.

5>What are the effect of purity and water vapor on the cooling
Water present in Ammonia systems creates a number of problems,
including internal system corrosion and creation of sludge that can
cause blockages in the systems. The presence of moisture impacts
the vapor pressure of the system. This combined with corrosion and
sludge, substantially impacts the efficiency of your system – with
a notable deterioration even at levels of just 0.5%.
Other impurities such as O2, N2, and hydrocarbons will have a
similar impact, increasing the risk of corrosion, stress corrosion
cracking and system performance drops.
