Thermodyamic, ecoomic analysis and desiging of heating system for the swimming pool present at NIT rourkela

Abstract

The swimming pool at NIT Rourkela, presently, has no heating system to heat the pool water during winters. Therefore, it is rendered unused during winters. The focus of this project is on designing an efficient and economically viable system to heat the swimming pool.
Temperatures of pool water and air above the surface of pool water were recorded for the month of November (2010). Using this data, losses associated with the pool were calculated and were found to agree completely with the literature data. Three systems were proposed based on: heat pumps, natural gas heaters and solar based water heating system. A design has been proposed for solar based water heating system. Many models of heat pumps were considered and a detailed cost analysis was made. For natural gas heaters, different models were considered and cost analysis was carried out. Annual operating cost of heat pumps and
natural gas heaters were compared and natural gas heaters were found to be about 1.8-3 times costlier than heat pumps. A combination of solar heating and a conventional heater in equal proportion has been proposed for a perfect heating system. Thermodynamic and economic analysis and designing of different systems for pool heating has been carried out in this work.
