Abstract

To study the feasibility of using ceramic plate solar collector to raise the temperature of aquaculture water in winter, the water heating experiments under different working conditions were carried out, the water temperature increment and heat gain of the collector were compared and analyzed by measuring the main operating parameters, and the influence of different working conditions on the heat collection effect was discussed. Results showed that the water temperature increment and heat gain of the ceramic plate solar collector were significantly related to the thermal insulation structure. In sunny days and at the same flow rate, the average water temperature increment of the solar collector with thermal insulation structure was 28.2% higher than that of the solar collector without thermal insulation structure. The accumulated heat gain and daily available heat gain were 36.5% and 56.0% higher respectively. In cloudy days, the average water temperature increment of the  collector with thermal insulation structure was 1.9℃ higher than that of the collector without thermal insulation structure, and the heat gain was negative. In addition, it was found that with the decrease of outdoor air temperature and the increase of wind speed, the water temperature increment and heat gain of the collector decreased. When the air temperature was lower than 0℃, the average water temperature increment of the collector without thermal insulation structure was 2.8℃ lower than that of the collector with thermal insulation structure, and the accumulated heat gain was 56% lower. It has demonstrated that the thermal insulation structure is more conducive to improve performance of the ceramic plate solar collector to raise the temperature of aquaculture water in winter.
