Abstract

This work is concerned with solar heating system calculations and thermal analysis of in-door swimming pools in winter season for selected Egyptian sites. The solar heating requirements for constant temperature were investigated. The design and the parametric analysis of the suitable roof-storage tank-integrated liquid solar collector as solar heating system in winter season of the proposed swimming pool which installed in different sites in Egypt are presented. The solar heating load demand is a function of hourly climatic conditions variables such as insolation, ambient temperature, wind speed and relative humidity. The heating solar thermal analysis of this proposed integrated system is divided into five parts; direct solar heat demand for heating pool water, heat loss due to radiation from the water surface, evaporation heat loss, convection heat loss and conductive heat loss to the ground. Furthermore, the winter season energy consumption model and life cycle cost of the solar collector is studied. The results are analyzed based on the proposed integrated solar heating system of in-door swimming pool with case study of 200m2 surface area and average depth 1.5m in winter season and in the selected sites of Egypt. Winter season is November, December, January and February and the selected sites are Cairo, El-Arich and Mersa- Matruh of Egypt. The results show that the maximum heating load appears in January for Mersa-Matruh and equals 71kW. The values of heat gains by solar collector are found for Cairo, El-Arich and Mersa-Matruh in winter. The system efficiency appears in Cairo, El-Arich and Mersa-Matruh according to its recording climate conditions in winter. The solar radiation has great effect on the solar collector's efficiency. The solar collector's efficiency is decreased as the wind speed is increased. The evaporated heat losses are great value in Mersa-Matruh according to its recording climate conditions and its location (coastal area). Relative energy save (Esr) values appears as Cairo, El-Arich and Mersa-Matruh according to its recording climate conditions (solar radiation).
