摘要：
Energy is an important material foundation for the current national accounts and social economic sustainable development. With the continued rapid growth of social and economic development and energy demand, the environmental pollution is worsening, so the development and use strategy of the alternatives to fossil fuels, such as solar energy and biomass renewable energy, attracted more and more attention. Based on China's rural industrial structure adjustment and industrial model of development situation of farmers in the present, the suitability of biomass energy as an auxiliary energy for solar energy adsorption refrigeration system was studied. An adsorption refrigeration experimental station was set up, which was driven by solar energy and biomass energy for the study, and the matching suitability of energy coupling by 2 heat sources was experimentally studied. Whether biomass energy and solar energy matched or not had a greater impact on the capacity of the system, reflecting that the cooling capacity of the system and the heat load of the end had the change characteristics in the same direction. Biomass boilers and solar absorption refrigeration system combined with the actual match drive and operation were analyzed. In this paper, we studied the biomass energy and solar energy suitability (coupling process) problems by the system simulation and experimental testing. The operating conditions of series and parallel of dual heat sources were dynamically simulated using the MATLAB software, and the nonlinear least square method was used for data processing and analysis. The results showed that: when operating in series, according to the circulation under the mode 2 condition, the system could achieve better heat transfer; when it was in the parallel operation, by the research on the energy supply by solar energy and biomass jointly, combined with the analysis of the cooling requirement and economic operation mode of the end of the system, the optimum return flow distribution ratio for the energy supply jointly by solar and biomass energy was in the range of 0.5-0.6, and 3 modes of economic operation suitable for the joint energy supply by dual heat sources were proposed. The results can provide the reference for improving the stability of the refrigeration system performance and achieving the effective integration of solar energy and biomass energy. © 2016, Editorial Department of the Transactions of the Chinese Society of Agricultural Engineering.
