Vapour Absorption Cycle Questions

AI Thread Summary
The discussion focuses on the functioning of vapour absorption cycle machines, specifically water ammonia refrigerators. The water absorber plays a crucial role by facilitating the absorption of ammonia, which is typically in a gaseous state in the solution. The heat release during absorption occurs as ammonia transitions from gas to liquid, condensing in the water-ammonia solution. This process is essential for the refrigeration cycle to operate efficiently. Understanding these mechanisms is vital for effective research on absorption refrigeration technology.

Questions on absorption coolers
Hi all,

I'm doing some research on vapour absorption cycle machines, mainly water ammonia refrigerators.
I've got a few questions.

1. What is the role of the water absorber? ie why do we need the water?
2. In the absorber we have a water ammonia solution. Is the ammonia a gas in the solution (like C02 in coca cola) or liquid, like mixing bourbon and coke (bad example I know)
3. There is always a mention of heat being released in absorption. Is that because the ammonia is becoming a liquid in the water-ammonia solution? is the absorption process condenses the hot gaseous ammonia?

Any help would be fantastic

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
