Ammonia Refrigeration System Schematic

Industrial refrigeration system basics ammonia refrigerant.

Ammonia refrigeration system schematic. A simple and practical absorption system using ammonia as refrigerant and water as absorbent described in the previous articles is an example of single effect cycle system for vapour absorption refrigeration system. Ammonia refrigeration systems operate in a similar manner to fluorocarbon systems but have several key differences. As a result any ammonia based refrigeration system is going to present a risk of accidental exposure to high concentrations of ammonia. While you will not usually find an ammonia based system inside a home ammonia is a very toxic substance and the refrigerators are very expensive they are used in factories that need large refrigeration devices that can cool substances very quickly.

The high pressure ammonia liquid flows through the expansion valve you can think of the expansion valve as a small hole. The compressor compresses the ammonia gas. 5 during this presentation we will discuss brief background on ammonia and its uses ammonia the refrigerant ammonia refrigeration the technology how is ammonia different compared to other refrigerants. An introduction to ammonia refrigeration systems.

Osha considers anhydrous ammonia to be immediately dangerous to life and health at a concentration of 300 parts per million ppm or 0 03. In this video were going to be looking at industrial refrigeration system basics with a focus on ammonia refrigeration systems we ll start at the basics and work our way up covering some typical systems for single stage two stage as well as cascade systems to help you learn the basics of industrial refrigeration. The coils on the back of the refrigerator let the hot ammonia gas dissipate its heat. That kind of accident could cause serious harm to human health.
