... power and a 1.3–4.6% increase in the refrigeration effect. When the chiller with the cooler operates under condensing temperature control, where condenser effectiveness is enhanced by staging all condenser fans, there is a savings in chiller power of 1.3-4.3% in some operating conditions in which...

...Jorge I. Herna´ndez; Roberto Best; Rube´n J. Dorantes; Claudio A. Estrada The studies of ejector refrigeration systems employing refrigerant R134a for air conditioning are scarce and nonexistent for ice making when its potential application in developing countries will lessen their refrigeration...

...Wen Wang; Tianfei Qu; Zhonghua Li; Ruzhu Wang Quantitative thermodynamic analysis demonstrates that an adsorption refrigeration cycle could get higher cycle performance by employing a suction line heat exchanger (SLHX). Low temperature evaporated gas not only helps to cool down the adsorbent...

...Shaoguang Lu; D. Yogi Goswami A novel combined power/refrigeration thermodynamic cycle is optimized for thermal performance in this paper. The cycle uses ammonia-water binary mixture as a working fluid and can be driven by various heat sources, such as solar, geothermal, and low temperature waste...

...Afif Akel Hasan; D. Y. Goswami Exergy thermodynamics is employed to analyze a binary ammonia water mixture thermodynamic cycle that produces both power and refrigeration. The analysis includes exergy destruction for each component in the cycle as well as the first law and exergy efficiencies...

...J. J. Rizza, Mem. ASME This paper presents an analysis of a cold thermal energy storage (TES) system operating in series with an R-123 chiller. A lithium bromide/water LiBr / H 2 O solution is used both as a refrigerant and as a cold thermal storage material. The refrigerant, liquid water...

... the primary secondary (PS) systems under partial load conditions for most existing chillers. The VW system consumes less compressor energy since it results in higher refrigerant temperature in the evaporator. The VW systems also have the decoupling capability of the primary and secondary pumping systems...

...T. F. Qu; W. Wang; R. Z. Wang Mass recovery can play an important role to better the performance of adsorption refrigeration cycles. Cooling capacity can be significantly increased with mass recovery process. The coefficient of performance (COP) of the activated carbon/ammonia adsorption...

...R. Z. Wang; M. Li; Y. X. Xu; J. Y. Wu; H. B. Shou A combined cycle capable of heating and adsorption refrigeration is proposed, and the experimental prototype has been installed. The system consists of a heater, a water bath, an activated carbon-methanol adsorption bed and an ice box. This system...
