How to increase COP and SCP of the absorption chiller

Click For Summary
SUMMARY

To increase the Coefficient of Performance (COP) and Specific Cooling Power (SCP) of a silica gel absorption chiller, focus on optimizing the heat exchanger design. The COP is defined as the heat removed by the evaporator divided by the heat supplied to the system, while SCP is calculated as the heat removed at the evaporator divided by the mass of silica gel used multiplied by the cycle time. Given the constraints of not being able to purchase additional absorption beds or increase the size of the existing ones, enhancing the efficiency of the heat exchanger is a viable solution. Proper terminology is crucial; ensure the correct use of "adsorption" when referring to silica gel systems.

Dear all,

I would to like to ask do anyone have any idea on how to increase the COP and SCP(Specific Cooling Power) of a silica gel absorption chiller?
COP= Heat removed by evaporator/ Heat supplied to system( normally is the hot water supplied to the absorption bed)

SCP= heat removed at evaporator/ mass of silica gel( 1 kg silica gel is being used in the experiment)*cycle time

Currently we have two bed of silica gel absorption bed, neither the faculty is willing to purchase extra absorption bed( which able to reduce the cycle time) nor change a bigger size of absorption bed ( which able to increase the mass of the silica gel to be put inside ).

I am wondering what can i do else to improved the efficiency, perhaps to change the better heat exchanger or anything else? @.@

Thank you everyone

I would contact the manufacturer of the exchanger itself, they'll have the best ideas for their specific model.

Also, are you sure it's not adsorption? With Silica gel, I'd expect this to be an adsorption unit. Just trying to ensure you are using the proper term when discussing this in the future, as the two processes operate differently.
 
Sorry should be adsorption... Typed wrongly... Tq
