Abstract: Heating effect of ceramic plate solar energy collector and vacuum tube solar energy collector was compared in an experiment to screen a high-efficiency, environmental friendship and economic method for water warming in aquaculture. Results showed that there was slightly higher maximum range of temperature heating-up per unit area by the ceramic plate collector (0.71 ℃) than that by vacuum tube collector (0.65 ℃) at irradiance of 230-1100 W/m2and water flow of 200-400 L/h, without little effect of ceramic plate collectors on the aquaculture water quality. Also, there was lower daily useful energy (q17) in the ceramic plate collector than that in the vacuum tube collector, which may be contributed to the excessively lost heat of the ceramic plate collector. The excessive thermal loss was improved by adding thermal insulation structure. The finding showed that the ceramic plate collector has the advantages of low price and simple structure, and the very similar temperature increasing effect as the vacuum tube collector in aquaculture water under the same working conditions, so the ceramic plate collector having the potential to replace vacuum tube collector.
