Buildings account for almost 40% of global energy consumption. Due to the high consumption chilled water plants, various studies have optimized chiller loading in plants with multiple chillers conservation. However, few dual-temperature even though better efficiency could be achieved than that typical single-temperature plants. This paper proposes two optimal control strategies strategy B and C...

Absorption cooling technologies converting excess heat and renewable resources to energy have shown progress in recent years. In this study, two 400 kW LiBr solution absorption chiller types with series parallel connected are analyzed over a range of parameter values better understand their applicability for different uses. Thermodynamic models the components were constructed validated. The per...

A low-cost medium-power carbon dioxide (CO2) laser system is designed, constructed, and characterized to produce coherent, monochromatic radiation in the infrared region. The cavity simulated designed by using ZEMAX optic studio. switch-mode high-tension pump source constructed a flyback transformer NI Multisim study voltage behavior at different node points. prototype cooling system/chiller bu...

The eating quality of meat is a function of the animal production and carcase processing that has been applied. While live animal factors (animal age, nutrition, breed, pre-slaughter stress) often have a marked effect on beef eating quality, in many cases the treatment of the carcase on the slaughter floor and in the chiller can have a far greater effect. This update, which follows on from Meat...

Faulty operations of Heating, Ventilation and Air Conditioning (HVAC) chiller systems can lead to discomfort for the occupants, energy wastage, unreliability and shorter equipment life. Such faults need to be detected early to prevent further escalation and energy losses. Commonly, data regarding unforeseen phenomena and abnormalities are rare or are not available at the moment for HVAC install...

Central air-conditioning systems account for the largest share of energy consumption in public buildings, wherein chiller room is main source. The current empirical strategies group control have difficulty realizing integrity, timeliness, and equipment adjustment accuracy lead to wastage. Therefore, operation strategy optimization model great value achieving savings. This study proposed a stepw...
