This demonstration project comprises the design, construction and operation of a special monitoring system for a solar heating equipment at Topsham Swimming Pool situated at Exeter, Devon UK. The scheme consists of a 25 m x 10 m open air heated swimming pool with a total water volume of 360 m**3. The solar collector is formed by a grid of pipes laid under the asphalt surface of a tennis court adjacent to the pool. The surface area of the collector is 560 m**2; the semi-rigid P.V.C. pipes (i.d. 9.5 mm) were laid lengthwise over the screeded hardcore foundation for the court with a spacing between the pipes of 125 mm. The solar collector is connected to the main pool circulation system. A monitoring system was designed and installed and monitoring carried out over the 1982 and 1983 seasons of use. The performance results are summarized in a number of tables, such as energy output, average daily incident solar radiation, monthly average collection efficiencies. The total energy delivered by the solar collector to the pool during the 1982 season was 10 303 Kwh and during the 1983 season 17 658 Kwh. The seasonal collection efficiency for the 1982 and 1983 seasons of use were 4.2 % and 5.6 % respectively. The maximum recorded daily collection efficiency was 12.3 %. Recommendations to improve the operating behaviour and energy balance of the plant are given, such as + reducing the pool water temperature, which increases the collector efficiency (the temperature was actually kept at 27 degrees C during 1982 and 1983 seasons). + providing a removable plastic pool cover to reduce the energy losses.
