Solar ponds are characterized by high storage capacity and the ability to provide a stable continuous power source. Careful selection of extraction rate helps maintain supply temperature in range suitable for operation an absorption unit. This study proposed system which solar pond is coupled with chiller investigate resulting advantages. The cooled using water upper convective zone, ensures th...

This study was conducted to determine the prevalence of Salmonellae contamination of chicken carcasses in slaughterhouses in central Iran (Yazd province). 435 samples were obtained from liver, breast— before and after chilling—and bacteriological and serological examinations were done. The results showed that the rate of contamination of liver, breast meat—before and after chiller—were 8.1, 18....

In this study, enhancements of thermal conductivities of ethylene glycol, water, and synthetic engine oil in the presence of copper (Cu), copper oxide (CuO), and multi-walled carbon nanotube (MWNT) are investigated using both physical mixing method (two-step method) and chemical reduction method (one-step method). The chemical reduction method is, however, used only for nanofluid containing Cu ...

The aim of the current study was to assess the safety of bronchoscopy-guided radiofrequency ablation (RFA) and compare the effectiveness between new internal cooled-RFA and standard noncooled-RFA. Normal lungs from sheep were used (n=6). Internal cooled-RFA and standard noncooled-RFA were set to assess the most suitable RFA conditions, such as power output, flow rate and ablation time. Internal...

Dynamic models of liquid chillers are gaining importance in recent years as tools for evaluating feedback controllers and to study transient system performance in general. Such system models consist of component models for the heat-exchangers, the compressor and the expansion device. The modeling of the heat-exchangers is particularly significant as they constitute the largest thermal capacitan...

Absorption chillers present opportunities to utilize sustainable fuels in the production of chilled water. An assessment of the steam driven absorption chiller at the University of Idaho, was performed to quantify the current exergy destruction rates. Measurements of external processes and flows were used to create a mathematical model. Using engineering equation solver to analyze and identify ...

Chiller adalah mesin refrigerasi yang fungsi utamanya mendinginkan air pada sisi evaporator. Air kemudian dialirkan ke AHU (Air Handling Unit) untuk didinginkan dan dihembuskan dalam ruangan. Penghapusan panas atau dimulai di Mesin ini memiliki keunggulan lebih hemat energi digunakan gedung bertingkat. Penelitian bertujuan merancang membangun chiller berkapasitas 6 KW, menggunakan sistem kompre...
