Absorption vs Electric Chiller
Various energy resources
reduce costly electricity bills;
More environmentally friendly,using water and lithium
bromidewhich are natural as refrigerant
medium,no CFCs;
Few moving parts enable quietand vibration-free operation;
Reducing the size of the requiredboiler or even eliminating the
need
for a boiler.
