摘要
１前言蒸汽压缩式循环和蒸汽型、直燃型吸收循环是目前应用最广的制冷循环。压缩式循环的能效比一般为２．５－４．５，其折算后的一次能源利用率大概为０．９～１．５。吸收循环直接由热驱动，其能效比一般在０．７～１．２左右。直燃型吸收循环由于高压发生器炉膛与溶液...
By using both work and waste heat of the diesel engine, an integrated absorptioncompression cycle is proposed and analyzed. The performance of this cycle is comparedwith those of conventional vapor compression refrigeration cycle and direct-fired absorptionrefrigeration cycle. The results indicate that, due to effective utilization of different gradeheat energy and reduction of irreversible loss, a COP improvement of 19% and 58%, respectively over conventional compression system with R22 as working fluid and direct-firedlithium-bromide absorption system, can be accomplished.
