...M. J. Morales; S. A. Sherif The purpose of this study is to investigate how the heat exchanger inventory allocation plays a role in maximizing the thermal performance of a two-stage refrigeration system with two evaporators. First, the system is modeled as a Carnot refrigerator and a particular...

...Mohamed A. Antar; Syed M. Zubair Thermoeconomics is defined as attaching monetary values to heat exchanger conductances of a given plant. In this study, optimum allocation of heat transfer inventory for heat exchangers in a refrigeration system with specified power input or cooling capacity...

...Douglas K. Priedeman, Mem. ASME; Michael A. Garrabrant; James A. Mathias; Roger E. Stout; Richard N. Christensen This research effort involved experimentally testing an advanced-cycle, ammonia-water absorption chiller with a cooling capacity of 17.6 kW (5 refrigeration tons (RT)). The system...

...Chi-Chuan Wang, Senior Researcher, Mem. ASME; Min-Sheng Liu, Associate Researcher; Jin-Sheng Leu, Researcher This study experimentally investigates the effect of circuitry on the refrigerant-side pressure drops of plate finned tube evaporators. Experiments were performed with countercross, parallel...

...Mohammad Yaqub; Syed M. Zubair The capacity control of a vapor-compression refrigeration system is investigated for three different capacity control schemes. In a hot-gas by-pass control scheme, the refrigerant is by-passed from the compressor and injected back into the suction line to decrease...
