Investigating the pool boiling process in absorption chiller generator by studying valid parameters may enhance chiller?s COP. In present study, transient 2-D numerical modelling of LiBr/H2O solution was carried out using two-phase Eulerian-Eulerian approach, extended Rensselaer Polytechnic Institute model and renormalization group k-? turbulence model. The applied on three types bare, notched ...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

This research is proposed to fully investigate the performance of a single-effect water/lithium bromide absorption chiller driven by geothermal energy. Since cycles are considered as low-grade energy cycles, this innovative idea rejecting fluid from single-flash power plant with would serve efficient, economical, and promising technology. In order examine feasibility approach, residential build...

Although water-cooled chillers are more energy efficient than air-cooled chillers, a majority of chilled water systems use air-cooled chillers. In cold weather climates, air-cooled chillers are capable of functioning in low ambient temperatures with few operational concerns, where as water-cooled chiller systems must be equipped to prevent cooling tower freezing. The integrated chiller system a...

Polygeneration of hydrogen, heat, and power has been shown to improve overall plant efficiency by creating more products and introducing synergy which improve fuel cell performance (Figure 1). The integration of an absorption chiller with a high temperature fuel cell for polygeneration of combined cooling, heating, hydrogen, and power is studied. Steady-state and dynamic computer models are uti...

To detect degradation in energy efficiency of a chiller in a chiller plant, a multivariate Gaussian mixture model is applied. This classification technique was selected to take advantage of an expected correlation between measurable state variables and equipment and operation specifications and system control targets. The hidden variable is the faultiness of the chiller and can take on one of t...
