Color of broiler skin was evaluated after exposure to organic acids under various concentrations and simulated potential plant application conditions. Breast skin from chilled broiler carcasses was treated with acetic (AA), citric (CA), lactic (LA), malic (ML), mandelic (MN), propionic (PA), or tartaric (TA) acids at 0.5, 1, 2, 4, and 6% concentrations. Each acid and concentration was applied i...

The current study aimed at delving into the thermodynamic of a trigeneration cycle based on biomass fuel, combined with an Organic Rankine Cycle (ORC) and absorption chiller. Biomass fuel is purely produced from Municipal Solid Waste (MSW). Energy exergy analyses were carried out using solar collector employing optimized characteristics to provide required thermal energy ideal condition utilizi...

This paper presents a semi-empirical steady-state model of an air-cooled water chiller. The first part of the paper shows how the model is built by associating a scroll compressor and two heat exchanger sub-models. The second part of the paper presents the parameters identification process based on published manufacturer data (for the compressor and the whole chiller models). The only encounter...

Ammonia/water absorption chillers are driven by low-grade heat and cover wide refrigeration temperatures. This paper analyses single-stage ammonia/water chillers. A numerical model was developed based on the exchanger performance. The captures variational performances describes actual cycle with varying boundary conditions. detrimental effects of refrigerant impurity were analysed quantitativel...

Dynamic models of vapor compression systems are important tools for HVAC engineers in the development and evaluation feedback control and fault detection and diagnostic (FDD) algorithms. Significant literature exists on dynamic models of vapor compression systems. Much of it is restricted to air-to-air systems and few papers deal with liquid chillers. Most of existing liquid chiller models revi...
