Potential Assessment of Hydrofluoro Refrigerant‐Based Adsorption Cooling Systems
To contribute to the climate goals set by the Kigali amendment, the present study explores the potential of hydrofluoro refrigerants for adsorption cooling applications. A performance analysis is carried out in the present study using Maxsorb III activated carbon for the commercial hydrofluoro refrigerants of R134a, R32, R410A, and R1234ze(E) for an air‐conditioning application. The distinct advantage of avoiding additional components and heat exchangers of such a commercial hydrofluoro refrigerant‐based adsorption system when cascaded with a commercial vapor compression refrigeration (VCR) system is explored in the present study, through various cascaded configurations. The working pair of Maxsorb III–R1234ze(E) is seen to yield the best cooling performance among the considered pairs, in terms of both Coefficient of Performance (COP), specific cooling energy (SCE), and lower regeneration temperatures. Furthermore, a COP enhancement of over 60% is estimated for the VCR system with an appropriate cascaded configuration with the working pair of Maxsorb III–R1234ze(E). The present study identifies the potential of the upcoming low‐GWP (global warming potential) hydrofluoroolefins (HFOs) for their deployment in the adsorption cooling systems for load reduction.
