低温余热驱动的吸收压缩复合式热泵(ACHP)系统压缩特性研究
Study on the compression properties of Absorption-Compression integrated Heat Pump driven by low-temperature waste heat
摘要
Abstract
This paper established a model for absorption -compression integrated heat pump (ACHP) driven by geothermal tail water, and investigated the effects of compression ratio on the system performance . According to previous optimized parameters obtained from the model, the experiment platform was built and using ammonia as the working fluid was studied experimently. The results showed that the concentration difference increased with the growing of the compression ratio and the absorb pressure. The COP increased with the growing of the absorb pressure. But the COP first increased then decreased with the change of the compression ratio. The experimental results of ACHP and the theory results had consistency. When the compression ratio was 3.8 and the concentration of dilute solution was 38%, the concentration difference was about 14%. The error of the experiment platform after optimization between the experiment results and the simulation results within 5%.关键词
