ABSORPTION SYSTEMS

Absorption chillers can be useful in cooling industrial spaces, where they also minimize the energy consumption by using waste heat. Our chillers are excellent for providing year-round space cooling for a wide range of process facilities.

The five major components of an absorber chiller are absorber, evaporator, heat exchanger, generator and condenser. The basic operation principle of all absorption chillers is similar: If the pressure system is low, absorption fluid evaporates and removes heat from chilled water. Absorption solution regeneration follows, using steam, hot water or any other relevant heat source.

There are two well known types of absoption chillers, LiBr-Water type and Water-NH3 type. The first one is typically used when the temperature at which you want to cool down the fluid is above 4.5 ºC. For processes demanding temperatures below 4.5 ºC down to -30 ºC the water – NH3 absorption chillers are the most interesting solution.

The refrigerant for LiBr absorption chillers is water solution while the absorbent is lithium bromide for temperatures of 4.5 ºC and above. If you need to cool below 4.5 ºC, we can install a system comprising ammonia as the refrigerant and water solution as the absorbent.
