Study and Investigation Analysis of Significant Aspects of Mechanical Draft Cooling Tower Performance

Mechanical Engineering

Cooling tower is an integral part of every industries central Air Conditioning plant which have water cooled condenser. Basically cooling tower are heat rejection devices used to transfer heat from hot water to the atmosphere air. In this project first we have a review study is carried out to investigate different types of cooling towers, their application, performance, usage and working principles, which can be useful in the HVAC plants as well as other energy stations. A number of investigations have been considered to reveal differences between the used cooling towers. The process parameters such as inlet Air Wet bulb Temperature, Flow rate of Water and fills porosity have more influence on Thermal performance of cooling tower. The Temperature of outlet water is maintained nearest to inlet air wet bulb temperature to obtain the best Thermal Performance of cooling tower. Finite element method is one of the powerful numerical techniques to solve the complex physical phenomenon that are governed by the differential equations. The performance parameters like range, approach, cooling capacity, evaporation loss liquid to gas ratio have been evaluated when the plant is operated at full load and part load under the same water flow rates. Effectiveness of the cooling tower can be increased up to 20% by optimizing the liquid to gas ratio (L/G) of the cooling tower. Likewise other parameters such as range, tower characteristic ratio can also be increased considerably. In this paper present the calculate thermal design data by practical reading which effect the performance of cooling tower and for assembly model of cooling tower using fusion360. For taking practical reading temperature sensor and thermocouple is used.
