摘　　要：针对目前燃煤锅炉供暖污染严重的问题,提出了一种利用风能供暖的系统,并对该系统的工作原理和储能实例进行了阐述;考虑到风能的不稳定,提出了利用高压压缩空气进行储能并对储能容积进行了计算。针对目前柱塞式压缩机效率低的问题,对液体活塞式压缩机和列管式换热器进行集成创新,提出了一种新型高效换热及热能再利用的压缩机,并对该压缩机的工作原理和节能效果进行了分析,说明了该新型压缩机具有较高的效率。用FLUENT软件对该压缩机进行了仿真,说明了该压缩机可以实现近似的定温压缩过程。利用该新型压缩机,能有效提高压缩机的效率和系统整体效率。A novel heating system using wind energy is proposed to replace the traditional coal-fired boiler heating system which is the main pollution source in the winter. The working principle and an example of the energy storage of novel heating system are explained. Considering the fluctuation of wind energy, the high-pressure compressed air is used as an energy storage method and the capacity of energy storage is calculated. To solve the low efficiency of heat exchange in a piston compressor, a novel compressor which can realize both a high efficiency of heat exchange and the heat energy recycling is proposed. The working principle and energy conservation effect of the novel compressor are described. It is shown that the e ftcieucy of novel compressor is higher than the piston compressor. It is based On the integration of the liquid piston compressor and the shell and tube heat exchanger. The novel compressor is simulated with FLUENT software. It is shown that this novel compressor can realize the approximate isothermal compression process, therefore the novel compressor can effectively improve the efftciency of the compressor and the whole system.
