内江棉纺织厂原安装有50年代生产的ZP-40/5型三效立式蒸汽喷射制冷机三套,十多年来,虽运行稳定可靠,操作管理简单,但单台产冷量小,耗能源多。80年,我们成功地将三套ZP-40/5改造为ZP-140/15型制冷机。每套仅花费两万多元资金。产冷量达145×10~4kcal/h,提高了1.8倍。蒸汽单耗由4 kg/10~3 kcal,降低至2.38kg/10~3 kcal节约蒸汽40.5%,收到了高效节能的效果。 Neijiang Cotton Mill originally installed three sets of ZP-40/5 three-effect vertical steam jet refrigerators produced in the 1950s. Although the operation was stable and reliable and operation management was simple over the past ten years, the single cold- More energy consumption. For 80 years, we successfully transformed three ZP-40/5 into ZP-140/15 refrigerators. Only cost more than 20,000 yuan per set of funds. Cooling capacity of 145 × 10 ~ 4kcal / h, an increase of 1.8 times. The unit consumption of steam is reduced from 4 kg / 10 ~ 3 kcal to 2.38 kg / 10 ~ 3 kcal, saving 40.5% of the steam, which has received the effect of high efficiency and energy saving.
