Reference

The direct-fired absorption chiller uses fuels like natural gas, biogas, or oil to generate heat for cooling. It uses a lithium bromide solution as the absorbent and water as the refrigerant.

The system includes key components such as generators, condenser, evaporator, absorber, heat exchangers, burner, vacuum pump, and sealed pumps.
