High Purity R717 Ammonium Hydroxide Gas Used In Refrigerator For
R717 refrigerant ammonia is one of the most widely used medium
temperature refrigerants.Refrigerant ammonia standard of
solidification temperature is 77.7 ℃, the evaporating temperature
of 33.3 ℃, the condensing pressure generally at room temperature is
1.1 ~ 1.3 MPa, even when the summer cooling water temperature as
high as 30 ℃ is never greater than 1.5 MPa. The unit standard
volume of refrigerant ammonia is about 520kcal/m3
Everlast AC has been a major supplier of R717 for more than 20
years and has been able to provide R717 technical and product
management support in 20 countries on five continents.
2. Advantages of ISO Tanks ammonia R717
1> Cool by nature and meet environmental regulations
2> Easy to obtain, low price, moderate pressure, a large amount
of refrigerant, high heat release coefficient, the little solution
to oil, small flow resistance, easy to find when leakage.
3> Ammonia is one of the most widely used medium temperature
refrigerants. (–50 to +15°C)
4> Ammonia has a good water absorption, even in low-temperature
water will not precipitate out of the ammonia solution freezing, so
the "ice plug" phenomenon will not occur in the system
5> Use time over 100 years and have rich experience
Refrigerant grade Ammonia Gas R717 is cheaper than others, it is a
quarter of the price of fluorine Refrigerant; The refrigerating
capacity of the unit volume is twice as high as that of fluorine.
The investment of ammonia equipment is smaller than fluorine
refrigeration equipment, and the daily maintenance cost of
refrigerant is small. Therefore, the international large-scale
refrigeration equipment generally adopts ammonia refrigeration
system. For example large food and beverage cold storage, ice
factory, packaging plant, large commercial refrigeration equipment,
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.
