        EXPERIMENTAL INVESTIGATION AND HEAT TRANSFER ANALYSIS OF INNOVATIVE THERMAL MECHANICAL REFRIGERATION SYSTEM COMPARED TO ELECTRIC COMPRESSOR 

        Sleiti, Ahmad K.; Al-Ammari, Wahib A.; Al-Khawaja, Mohammed ( American Society of Mechanical Engineers (ASME) , 2022 , Conference)
        The current electric refrigeration and air condition systems are major causes for ozone depletion and global warming. These systems consume large percent of the worldwide gross production of electricity (around 17%). ...

        Experimental investigation on the performance of a novel thermo-mechanical refrigeration system driven by an expander-compressor unit 

        Ahmad K., Sleiti; Al-Ammari, Wahib A.; Al-Khawaja, Mohammed; Saker, Ahmad T. ( Elsevier , 2022 , Article)
        Operating thermos-mechanical refrigeration (TMR) ejector-based and organic Rankine cycle-based refrigeration systems at ultra-low temperature heat source (60 °C to 100 °C) is challenging and limited by their low coefficient ...

        Experimental investigations on the performance of a thermo-mechanical refrigeration system utilizing ultra-low temperature waste heat sources 

        Ahmad K., Sleiti; Al-Ammari, Wahib A.; Al-Khawaja, Mohammed ( Elsevier , 2023 , Article)
        Experimental studies that investigate the utilization of ultra-low temperature (between 48 °C and 120 °C) waste heat, which forms 25 % of the global unrecovered waste heat, to drive thermal cooling systems are rare. Thus, ...
