Design and Development of Centralized Air Conditioning Plant Model with Water Cooled Chiller
Abstract
The work consists of how a proposed centralized air conditioning is designed and its criterion for a new building in college. Central Air Conditioners working is a complex and cumbersome topic which takes a lot of time and effort. It’s a difficult task to explain the entire parts, its working and maintenance. Here an effort is made to explain about the designing of Ducts used in a central A/C. A commercial building is taken for reference and each floor’s Duct designing is explained. It consists of three floors. The main objective is to create a thermally controlled environment within the space of a building envelope such as office space. The tentative air conditioning load for the system shall be 1.5 TR approx. Water-cooled chillers with secondary variable pumping system are proposed to make the system energy efficient. The duct design was started and using the duct sizer version 6.4 we calculated the optimum duct sizes required for the 3 floors. The duct dimensions for accurate flow of air volume to maintain the interior environment of the building in an optimal state is found. The design of air-conditioning includes heat load estimation, selection of Chillers, Pumps, Air Handling Units (AHU) based upon design, the model will be fabricated. Based on the design we fabricated the ducts through which the thermally cooled environment is developed. Results of this work included the design of accurate dimensions required for a building, Volume flow rate of air flowing in each room, Fabrication of the ducts and final prototype of a working water-cooled chiller was created.
