Erik CatesME 3322
Uses a heat source(gas or propane) to run a cooling process
Cooling is caused by heat absorption by refrigerant as it is evaporated, which removes it from the system
Refrigerant gas is then converted back to liquid form to repeat cycle
Most commonly used refrigerant is Ammonia
Generator- receives heat from source, produces ammonia gas
Separator- separates ammonia gas from water
Condenser- hot ammonia gas is cooled, condensed to liquid form
Evaporator- evaporates ammonia liquid, creates cold effect inside refrigerator
Absorber- absorbs ammonia gas into water
Dalton’s Law- the total pressure from gas mixture is sum of all partial pressures
Hydrogen doesn’t react with ammonia- hydrogen simply takes up space
In evaporator- hydrogen/ammonia mixture causes the partial pressure of ammonia to be lowered, which lowers the boiling point of the ammonia to below room temperature
No moving parts
Doesn’t require electricity
Quiet
Makes use of excess heat
No HCFC’s – harmful to environment
