Aquatherm Industries, Inc. Â announced it has received the industryâ€™s highest performance rating for vented solar pool panels with its flagship product, ECOSUNâ„¢. The announcement comes after competitive product Heliocol, received updated performance test results from the Solar Ratings & Certification Commission (SRCC), an independent third party performance certification agency for solar collectors.
Introduced in 1990, the ECOSUNâ„¢ Solar Pool Heater offered an innovative approach to solving the issue of wind-relief and moisture ventilation on rooftop installations. At the time, conventional wisdom for venting unglazed solar pool collectors was to separate each tube. While this design eliminated wind-load or moisture concerns, it dramatically reduced surface area and, subsequently, performance.
The inherent flaw in this â€œloose-tubeâ€ design, Â is its inability to protect pool water moving through the collectors from exposure to the elements, specifically a prevailing cooler ambient (outside) air temperature. As discovered through SRCC thermal performance testing, when the difference between ambient air and desired pool temperature exceeds 9 degrees F (e.g., ambient air temperature = 76 degrees F; pool temperature = 85 degrees F), performance of a loose-tube design suffers greatly due to the effects of wind and reradiation to the atmosphere.
Conversely, by directly incorporating vents into its signature sun-tracking â€œtube-and-web design,â€ Aquathermâ€™s ECOSUNâ„¢ offers a unique improvement over loose-tube solar collector designs. First, the ECOSUNâ„¢ collector utilizes a patented venting method, by which no material is removed from the product. When adverse weather conditions present high-wind scenarios, it is this proprietary venting system that activates, relieving any potential concerns. Second, fluted tubing gives ECOSUNâ„¢ a 10% increase in surface area, affording the collector maximum surface exposure to the sunâ€™s solar thermal energy.
According to SRCC certification, on that same 76 degree F clear day ECOSUNâ„¢ collectors are 86% more efficient at heating a pool to 85 degrees F. In addition, SRCC testing found Heliocolâ€™s loose-tube design was entirely unable to perform in cooler weather, whereas Aquathermâ€™s ECOSUNâ„¢ collector still performs at roughly 30% efficiency â€“ providing heat even in unseasonably cool temperatures.ambient air temperature, loose tube, performance certification, pool water, solar collector, solar pool collectors, solar pool heater, solar thermal energy, surface exposure
