Is ammonia a R717?

R717 (Ammonia) is refrigerant grade Ammonia (NH3) used in low and medium temperature refrigeration. It is a colourless, pungent, highly toxic gas but is a very efficient refrigerant with zero Global Warming Potential (GWP).

Why is ammonia R717?

R717 ammonia: The ammonia used for refrigeration systems based on the use of a compressor, condenser, expansion valve and an evaporator (Figure 11.2) is dry (anhydrous) in that there is no water in solution with it. It has the chemical formula NH3 but as a refrigerant, it is coded with the number R717.

What is refrigerant R717?

R717 is refrigerant grade high purity ammonia (NH3). The product typically is 99.98% pure with minimal levels of moisture and other impurities (< 200 ppm and < 5 ppm oil), making it ideal for use in all types of refrigeration systems, especially in the air conditioning industry. Ammonia 3.8 (99,98%). Max 200 ppm H2O.

Is R717 a natural refrigerant?

COOOL R717 is a natural refrigerant gas, with multiple applications in industrial refrigeration, especially in R744 cascade systems or in secondary fluid systems, such as glycol water. Its main characteristics are: High refrigerating power. GWP – Global Warming Potential = 0.

What type of refrigerant is ammonia?

Ammonia is the most environmentally friendly refrigerant. It belongs to the group of so called “natural” refrigerants, and it has both GWP (Global Warming Potential) and ODP (Ozone Depletion Potential) equal to zero.

Is r134a an ammonia?

“The thermodynamic properties of R-134a are such that about six volumes of refrigerant are required to produce the same refrigeration capacity as a single volume of ammonia, which means a larger compressor is needed for R-134a.

What type of ammonia is used in refrigeration?

anhydrous ammonia
To use ammonia as a refrigerant it must be pure, AKA refrigerant grade anhydrous ammonia. This ammonia must be at least 99.95% pure and cannot have a water content above 33 ppm or an oil content above 2ppm.

Is R717 refrigerant flammable?

R717 has a relatively high saturation temperature at atmospheric pressure, is highly toxic, mildly flammable and has a pungent odour.

Why ammonia is used in refrigerator?

Environment Ammonia is the most environmentally friendly refrigerant. It belongs to the group of so called “natural” refrigerants, and it has both GWP (Global Warming Potential) and ODP (Ozone Depletion Potential) equal to zero.

What refrigerant is ammonia?

Ammonia (NH₃) Ammonia (NH3) is a well-known refrigerant, particularly applicable in large, industrial plants where its advantages can be fully utilized without compromising safety. Ammonia is renowned for its favorable thermodynamic properties. In a wide range of applications, it outperforms synthetic refrigerants.

Is ammonia the best refrigerant?

Environment. Ammonia is the most environmentally friendly refrigerant. It belongs to the group of so called “natural” refrigerants, and it has both GWP (Global Warming Potential) and ODP (Ozone Depletion Potential) equal to zero.
