Numerical prediction of water-flow glazing performance with reflective coating

Tintai Chow, Chunying Li, Joe Andrew Clarke

Abstract: A novel design of double glazed system encapsulating water flow is proposed with enhanced solar energy capture. With continuous heat absorption by the flowing water, the indoor heat gain is reduced and solar energy becomes a service water heat source. A prototype of the water-flow glazing system, with reflective coating at the inner pane, was tested experimentally. A system model was established within the ESP-r simulation environment. The validated model was applied to study window performance when installed in the gymnasium of a large sports centre. The results show attractive water heat gain efficiency and reduction in electricity use in air-conditioning system.
