Economic feasibility of heating source conversion of the swimming pools

Abstract

Conversion from conventional heating systems is developed to address the emission of CO2 in the environment, global warming, rising costs, potential shortages of fossil fuels, for all energy source alternatives available. This study reviewed the economic feasibility associated with converting the current heat source to a renewable energy source of heating swimming pools located in Jordan. Many modern heating systems techniques are proposed in this study such as solar heat collectors, heat pump and photovoltaic assisted heat pump. Solar heat collectors are a device that collects and/or concentrate solar radiation from the sun and allow for heating the water. In addition, a growing interest in photovoltaic/heat pump systems is considered, which combines photovoltaic cells and heat pump systems. Hence converting solar energy into electricity and then heat through the heat pump. The Initial and operation cost for all proposed techniques is evaluated. As a result, it is found that the best economical alternative option that can be installed on the available area of the building is photovoltaic with a heat pump system during the heating season. The operation cost of the current source (diesel boiler) is about 179,974 US$ and the total cost of heat solar thermal collector is about 936,540 US$ but the total cost of the proposed photovoltaic/heat pump system is nearly 251,060 US$, which save about 45,134 US$ yearly of the total commercial building electricity bill that is selected with a payback period of fewer than two years. In addition, available space on the rooftop of the selected building is well fitted with photovoltaic panels which are around 2000 m2. This result suggests that utilizing a PV/HP system for hotel pools is advantageous both financially and environmentally.

Water and Energy Sustainability of Swimming Pools: A Case Model on the Costa Brava, Catalonia

“…The studies related to filtration during recirculation and disinfection to ensure pool sanitation [70] and the studies of water stress in the filter cleaning process [29,71,72] and water recovery [73][74][75][76] are of great importance in the research presented here. Regarding energy stress, water heating is a major challenge and air conditioning and dehumidification entail significant energy expenditure [36,[77][78][79]. To improve this expenditure, efficient heating with appropriate heat pumps is essential [80,81].…”

“…Thus, the issues of concern in the literature, at the level of water stress, are evaporation [42,[50][51][52][53][54]56,63,[65][66][67][68][69]83], filter backwashing [29,61,72,75,76], and water reuse and disinfection [71,74,76]. Regarding energy stress, the literature is based on energy consumption and cost [20,28,30,77,85,86,90], heating [31,78,79,81], simulation models and applicable technology [35,58,60,65,84,86,89], solar systems to reduce consumption [35,36,43,[91][92][93][94], and carbon footprint [12,[20]…”

Implementation of the dynamic balancing approach of a rotating composite hollow shaft

“…Rotor mass imbalance is a typical problem in rotating machinery, which is widely employed in a range of technical sectors [1][2][3] such as vehicles, aircraft gas turbine engines, electrical motors, and power generation. The imbalance term indicates the deviation and imperfections of the mass centre from the rotation axis [4].…”
