How is capacity control accomplished with a steam driven absortion refrigeration machine?

Capacity control in a steam-driven absorption refrigeration machine is typically accomplished by modulating the flow of the refrigerant and absorbent. This can be achieved through variable speed pumps or valves that adjust the amount of refrigerant circulating in the system based on cooling demand. Additionally, the machine may employ bypass lines to divert excess flow and maintain optimal operating conditions without overloading the system. These methods help ensure efficient performance while meeting varying cooling loads.
