R1233zd(E) and Dimethylacetamide-based Diffusion Absorption Cooling System
Abstract
This study investigates the feasibility of utilizing 1-Chloro-3,3,3-trifluoropropene (R1233zd(E)) as the refrigerant and Dimethylacetamide (DMAC) as the absorbent in a Diffusion Absorption Refrigeration (DAR) system. The thermodynamic properties of the R1233zd(E)-DMAC binary solution were experimentally determined, including pressure-temperature-concentration and enthalpy-temperature-concentration data. These experimentally obtained data were integrated into a detailed DAR system model. Simulations were conducted to evaluate system performance, focusing on the influence of generator temperature and solution concentrations on the Coefficient of Performance (COP) and circulation ratio. In addition, an exergy analysis was conducted. This approach allowed for identifying the locations and magnitudes of exergy losses and evaluating overall efficiency based on useful energy quality. The results demonstrate that the system exhibits a COP value of 0.4 at an optimal generator temperature of 114°C. This optimal temperature is significantly lower than that typically observed in conventional ammonia-water systems or other HFC-based DAR systems. Moreover, the system operates at considerably lower pressures. This study contributes valuable insights into the potential of R1233zd(E)-DMAC as a promising working fluid pair for sustainable and energy-efficient DAR systems, particularly those utilizing low-grade heat sources.
