Application of Natural Zeolites in Refrigeration
1985Publisher Summary Silica gels, activated alumina, and synthetic zeolites are commonly used in the refrigeration industry mainly for the purpose of desiccation of halocarbon refrigerants. However, natural zeolites cannot be used in refrigeration systems as mined and crushed.

Equations for Thermal Conductivity of Natural Refrigerants
International Journal of Thermophysics, 2001Experimental results for the thermal conductivity of ammonia, propane, butane, isobutane, and propylene are reviewed, with special attention given to the liquid phase. New equations for the thermal conductivity of these five substances applicable for practical use over wide ranges of temperature and pressure including the critical region are proposed ...

Performance characteristics of natural-refrigerants- based ejector expansion refrigeration cycles
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2009The thermodynamic analyses and comparison of three natural-refrigerants-based vapour compression refrigeration cycles (ammonia, isobutane, and propane) are presented in this article using a constant pressure mixing ejector as an expansion device. Optimization of the area ratio of the ejector is done based on maximum cooling coefficient of performance ...

Natural Working Fluids in Transport Refrigeration
2022There are currently many drivers pushing the transport refrigerationsector towards more sustainable refrigeration systems, being at the sametime more efficient and adopting natural working fluids (NWF) in placeof synthetics. Due to the variety of involved means of transport, on thedifferent and challenging boundary conditions and safety requirementsand

International Journal of Exergy, 2012
Irreversibility analyses of R290, R717, R718 and R744 are carried out in a compression refrigeration cycle. The effects of evaporator temperature, condenser temperature and isentropic efficiency on the irreversibility of the cycle and its basic components are investigated and exergy analysis of the cycle is also presented as a function of evaporator ...
