Ammonia Refrigeration System Design

A refrigeration system is based on a type of refrigerant gas which is constantly run through the system to gather and disperse heat.

Ammonia refrigeration system design. And a member of both ashrae and iiar. Today industrial refrigeration systems are the sole focus of more than 230 of our designers engineers installers and service experts. The purity of the anhydrous ammonia is vital to the properties that make it a good refrigerant. Industrial refrigeration systems primarily use ammonia as a refrigerant.

Many of the requirements of the process safety management standard 29 cfr 1910 119 are identified in this. Refrigerant grade anhydrous ammonia is a clear colorless gas or liquid and about 99 95 pure. Since 1959 fisher refrigeration has been designing and installing quality industrial ammonia refrigeration systems for the food processing cold storage pharmaceutical and chemical industries. Specifies criteria for materials design parameters marking and testing of valves and strainers used in closed circuit ammonia refrigeration systems.

The design of safe ammonia systems will be considered from two aspects. Our service department is one of the best trained in the industry while the parts department maintains an extensive inventory of genuine replacement. Ammonia refrigeration works much like industrial refrigeration systems using synthetic refrigerants with the major exception being that it uses anhydrous ammonia as the refrigerant. John is a registered p e.

Ansi iiar 3 american national standard for ammonia refrigeration valves. Stellar provides the most comprehensive range of refrigeration services available from custom design installation to aftermarket service and maintenance. Ammonia is 100 natural does not harm the environment and is the most efficient refrigerant available. The new and improved iiar 2 is the definitive design safety standard of the ammonia refrigeration industry.

John s professional interests include technical leadership hvac products and systems dx refrigeration industrial refrigeration geothermal system design thermal systems optimization building science and building energy management. These gases are made of many different substances most household refrigerants are actually a synthetic mixture designed for efficiency but ammonia based version simply use ammonia.
