The thermal performance of an absorption refrigeration system is greatly dependent on the physical and chemical properties of the working fluids used. %%EOF Because of ammonia’s widespread use as a refrigerant, comprehensive tables of thermodynamic properties are frequently needed by refrigeration engineers. Thermophysical Properties of Fluid Systems. The NH3 Calculator Web application calculates 30 thermodynamic and transport properties of ammonia. h�b```f``������cf`a�P�h�`a�X�*� ����3 "u����W00&1u5x.��mY����@��=���X�CCk0J40w0p44Xp�1h���Q ���`G�2�20l��i��G�)�@B�L@����؆��A�g�0 ��/� For transport properties the library uses equations presented in: The Registration includes free technical support for the duration of the subscription. 3 01307 Dresden Germany. But as these properties also benefit the thermodynamic efficiency in the system, it also reduces the operating costs of the system. The purity of the anhydrous ammonia is vital to the properties that make it a good refrigerant. Advanced Ammonia Refrigeration Systems Nov 5-12 2021 8-10am CST. Tel. : +49-172-7914607 Prof. Dr. Hans-Joachim Kretzschmar Wallotstr. It’s origins as a refrigerant can be traced all the way back to the 1800’s and it was one of the first refrigerants used in a variety of applications.

Accurate thermophysical properties are available for several fluids. ACKNOWLEDGEMENT The success of the 30th Annual Meeting of the International Institute of Ammonia Refrigeration is due to the quality of the technical papers in this volume and the labor of its authors. Acid is formed as a result of the breakdown of the refrigerant and oil. Ammonia is also readily available and inexpensive. Thereby plant construction cost will be lower. Air Conditioning - Air Conditioning systems - heating, cooling and dehumidification of indoor air for thermal comfort; Related Documents . The chemical, physical and thermodynamic properties of the refrigerant must suit the system and the working conditions at a reasonable cost. Ammonia refrigeration works much like Industrial Refrigeration systems using synthetic refrigerants, with the major exception being that it uses anhydrous ammonia as the refrigerant. Advanced Ammonia Refrigeration Systems Nov 5-12 2021 8-10am CST. Ammonia moves around the system and therefore vessels will often have more or less than the amount listed in the actual inventory calculation… It is hazardous when released in large quantities due to its toxicity. It allows 11 different combinations of input variables to be used in calculations. This need to estimate the quantity of refrigerant loss ranges from regulatory reporting requirements to determining whether or not additional refrigerant should be purchased.
