Question

How much ratio water and ammonia must be mixed in refrigeration?

Answer 1

Ammonia-Water Vapor Absorption Refrigeration System
The working of ammonia-water absorption refrigeration system is based on the simple vapor absorption refrigeration system. In this system ammonia is used as the refrigerant and water is used as the absorbent. The ammonia-water absorption system is used in the domestic as well the commercial applications where the requirement of the temperature is above 32 degree F.

The major advantage of the ammonia-water solution is that water has strong affinity for ammonia and they are soluble with each other in wide operating conditions that occur in different refrigeration applications. Further, the ammonia-water solution is highly stable and works well with many materials except copper and its alloys that get corroded in the presence of ammonia. We have already seen that ammonia is considered to be the most suitable refrigerant, however, due to its toxicity its applications are limited and it is not used in the air conditioning applications.
