Một mô hình tham số đặc tính chính xác sẽ có vai trò then chốt trong việc nâng cao tỷ lệ của quá trình phát hiện và chẩn đoán lỗi hệ thống chiller. Vì vậy nghiên cứu này đã thực so sánh đánh giá 3 phương pháp MLR, GRNN RBFNN đóng là để hóa các hoạt động Hai chỉ kê R2 RMSE được sử dụng tiêu chí ở giai đoạn huấn luyện hình. Sau đó, kết hợp với t-test cùng quy luật khảo sát khả năng Bộ dữ liệu ngh...

Two experiments (EXP), utilizing the skin attachment model (SAM), were conducted to determine the bactericidal activity of six potential carcass disinfectants [EXP 1: 20, 400, and 800 ppm sodium hypochlorite; EXP 2: 5% acetic acid (AA), 8% trisodium phosphate (TSP), and 1% sodium metabisulfite (SS)] during simulated scalder (50 C for 2 min), chiller (0 C for 60 min), or post-process dip (23 C f...

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....

We developed an appropriate Absorption chiller to "Solar cooling system" in 2010. In addition, we added the improvement to the machine. "Solar cooling system" can be easily constructed with the machine. and, we constructed the demonstration plant, and verified the utility

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 ...

The energy demand of industries accounts for about 30–35% world yearly consumption, a relevant percentage is due to the need heating and cooling demand. Solar technologies can be integrated in industrial processes reduce fossil fuels consumption as well related greenhouse gas emissions. This paper reports experimental analysis novel hybrid sorption-compression chiller refrigeration purposes cas...

Heat driven cooling technologies like vapour absorption and adsorption systems are environmentally friendly. Use of thermal compression in these systems saves precious and fast-depleting fossil fuel resources. Solar energy and low-grade waste heat can be effectively used in running these cooling systems. The present work focuses on the development of a solar-powered vapour adsorption based cool...
