Ammonia Refrigeration | Creative Safety SupplyAmmonia refrigeration is one of the older types of refrigeration that is still used today. While the average person doesn't realize it, just about all food and drinks that are purchased have been kept cold using ammonia refrigeration at some point along the way.
How Does an Ammonia Refrigeration System Work? | HunkerA refrigeration system is based on a type of refrigerant gas, which is constantly run through the system to gather and disperse heat. 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.

The Do's And Don'ts Of Ammonia High-Side PipingHigh-side piping can be simply described as the piping that connects various components of a refrigeration system that operate at, or near, the system condensing temperature. This includes, but is not limited to, condensers, receivers, thermosyphon oil coolers, purgers, and oil separators. Twenty ...
Purging Air From Refrigeration Systems - ACHR NewsThere are good reasons for purging air from your refrigeration system, operating efficiency being the main one; increased equipment lifespan is another. It's important, however, that correct purging procedures are used. This article will examine why air should be purged, and how it should be done ...
Refrigerant Piping - Baltimore Aircoil CompanyBecause copper and copper-bearing materials are attacked by ammonia, they are not used in ammonia piping systems. Steel piping, fittings, and valves of the proper pressure rating are suitable for ammonia gas and liquid. Ammonia piping should conform to ASME Standard B31.5, Refrigerant Piping and IIAR Standard 2, which states the following: 1.
Ammonia Chilled Water System | Commercial HVACMost chilled water air conditioning systems use compressors to compress the refrigerant so that it can be condensed in condenser coils. This system uses natural gas and a heat exchanger to compress the refrigerant so that the condenser can condense the refrigerant in the system.

CUSTOMER MANUAL – ANHYDROUS AMMONIAThe common metals are not affected by dry ammonia. Moist ammonia will not corrode iron or steel, but will react rapidly with copper, brass, zinc and many alloys, especially those containing copper. Only steel or ductile iron should be used for ammonia containers, valves, fittings and piping. Under normal conditions, ammonia is a very stable ...

Evaporative Condensers - Baltimore Aircoil CompanyEvaporative condensers are frequently used to reject heat from mechanical refrigeration systems. The evaporative condenser is essentially a combination of a water-cooled condenser and an air-cooled condenser, utilizing the principle of heat rejection by the evaporation of water into an air stream traveling across the condensing coil.
