VAPOUR ABSORPTION CYCLE

DOMESTIC ELECTROLUX REFRIGERATOR

 The domestic absorption type refrigerator was developed from an invention by Carl Munters and

Baltzer Von Platen. This system is often called “Munters Platen System”.

 This type of refrigerator is also called “Three-fluids absorption system”. The three fluids used in this

system are ammonia, hydrogen and water.

- The “ammonia” is used as a refrigerant because it possesses most of the desirable properties.

Though it is toxic, and not otherwise preferred in domestic appliances, it is very safe in this system

due to absence of any moving parts in the system and , therefore, there is the least chance of any

leakage.

- The “hydrogen” being the lightest gas, is used to increase the rate of evaporation (the lighter the

gas, faster is the evaporation) of the liquid ammonia passing through the evaporator. The hydrogen

is also non-corrosive and insoluble in water. This is used in the low-pressure side of the system.

- The “water” is used as a solvent because it has the ability to absorb ammonia readily.

Principle and Working of Electrolux Refrigerators.

Fig. 5.6. Shows a schematic diagram of an „Electrolux refrigerator‟. It is a domestic refrigerator and is

the best known absorption type of refrigerator. Here pump is dispensed with. The small energy supply

is by means of a heater which may be electric or gas.
