A solution is at its saturation point when
It has reached it’s maximum salt concentration
How do you limit a high-level in the concentrator/generator?
Open the concentrator bypass valve
Vapour pressure varies with the concentration of?
The solution
What type of heat is removed from the absorber into the cooling water
Sensible heat
What type of alcohol helps the lithium bromide refrigeration system
Octylalcohol
What will cause corrosion in the system
Noncondensible’s and oxygen
Water will boil at a lower temperature when its Put on a
High vacuum
The absorber and condenser are referred to as a
Heat sink
The operating cycle of an absorption system is
Continuous
Where will crystallization occur
In the strong solution leaving the heat exchanger
What is a lithium bromide absorption system commonly used for
Air-conditioning in large buildings
For applications below 32°F an ammonia/water cycle is employed, which is the refrigerant and which is the absorbent?
Ammonia is the refrigerant and water is the absorbent
If you increase the temperature of the lithium bromide the vapour pressure will
Increase
Why are ammonia systems seldom used for air-conditioning and large buildings
Because of the toxic properties of ammonia
What are the three main components that are similar in an absorption system and compression system?
Condenser evaporator and expansion valve
