Condensation heat removal due to the combined impact of natural convection and radiative cooling

نویسندگان

چکیده

The work examines the heat exchange characteristics of a condenser in which removal refrigerant condensation occurs due to natural convection and radiation cooling. exchanger is designed reduce energy costs for heat. Unlike traditional air cooling condensers, it uses cooling, method based on its transmission form infrared through planet’s atmosphere into surrounding outer space. A calculating thickness radiating plate has been developed. To minimize material consumption cost, distance between tubes reduced 40 mm, aluminum 0.32 mm. inner diameter coolant channels 1 For experimental study condenser, an stand working R134a was Theoretical studies transfer have carried out. coefficient exchanger, area surface, from 10.3±1.36 18.7±2.47 W·m–2·°C–1, when temperature 12.8...21.9 °С higher than atmospheric air. operability shown both during day at night, presence precipitation rain snow, high level cloudiness. capacity filling are comparable air-cooled condensers with forced circulation. At same time, does not consume electricity. It can be used stationary refrigeration systems (in data processing centers, commercial equipment, conditioners) increase their efficiency

Lattice Boltzmann simulation of EGM and solid particle trajectory due to conjugate natural convection

The purpose of this paper is to investigate the EGM method and the behavior of a solid particle suspended in a twodimensional rectangular cavity due to conjugate natural convection. A thermal lattice Boltzmann BGK model is implemented to simulate the two dimensional natural convection and the particle phase was modeled using the Lagrangian–Lagrangian approach where the solid particles are treat...

Natural Convection Heat Transfer within Octagonal Enclosure

The problem of steady, laminar and incompressible natural convection flow in an octagonalenclosure was studied. In this investigation, two horizontal walls were maintained at a constant hightemperature, two vertical walls were kept at a constant low temperature and all inclined walls wereconsidered adiabatic. The enclosure was assumed to be filled with a Bousinessq fluid. The studyincludes comp...

Natural and Mixed Convection Heat Transfer Cooling of Discrete Heat Sources Placed Near the Bottom on a PCB

Steady state experiments have been conducted for natural and mixed convection heat transfer, from five different sized protruding discrete heat sources, placed at the bottom position on a PCB and mounted on a vertical channel. The characteristic length ( Lh ) of heat sources vary from 0.005 to 0.011 m. The study has been done for different range of Reynolds number and modified Grashof number. F...
