In a single effect absorption system, heat enters the system through what two components? -
✔✔Generator & Evaporator
A double effect absorption chiller has? - ✔✔Two Generators
Capacity is controlled by what industry standard device? - ✔✔Automatic Steam Valve
What causes efficiency loss in an absorption chiller? - ✔✔(All The Above) Non-Condensable
Air, Dirty tubes in the Heat-Exchanger & Inefficient Tower Cooling
To generate hot water, what must occur? - ✔✔Generator solution is allowed to flow directly
