以前在传统主机厂负责传统皮带轮压缩机,由发动机驱动,由于对油耗影响不那么明显COP一直没有受到特别的重视,主要只关注压缩机制冷能力。后来进入电动汽车行业,由于电动汽车续航里程焦虑的驱动,开始慢慢关注起电动压缩机COP。直到后面做电动车热泵系统,以及随着对热泵系统、对压缩机越来越深入的挖掘,开始更加关注起压缩机COP,并开始探究起压缩机的容积效率和等熵效率。 容积效率和等熵效率定义: 容积效率 关于压缩机容积效

无油润滑涡旋压缩机结合了无油润滑压缩机与涡旋压缩机两者的优点。无油涡旋压缩机不仅在结构、工作效率、可靠性、震动等方面有着不可替代的优势,同时具备以下几大优点:

Single-stage Ammonia Refrigeration Cycle Single-stage refrigerator is a wide used refrigerator. It can be applied to produce ice, used as air conditioning, used for food refrigeration and industrial processes and so on.  Single-stage refrigeration cycle is the refrigerant in the refrigeration system process to have four stage which are compressed, condensation, throttling, and evaporation.  It will complete the […]

无油润滑压缩由于具有压缩气体不被润滑油污染、节约大量润滑油、净化流程、简化设备、延长触媒的使用寿命、提高产品产量及质量等优点,而广泛应用于化工、国防、冶金、石油炼制、通讯、仪表、食品、医疗、纺织等部门。

Scroll compressor was created at 1905, by a French engineering Leon Creux. But as the technology of the period was not advanced to construct a working product, first practical scroll compressors did not appear on the market until 1980s. Since 1970s, the energy crisis and the appear of high precision CNC milling machine brings the […]

Scroll compressor was created at the beginning of 1900s. Due to the limitation of processing technology, there are no product before the 1970s. Now the scroll compressor is the major compressor used by air conditioning. However, there are still many  technology shortages of oil-free scroll compressor. I find it hard to get the right equations for calculation […]

涡旋压缩机从20世纪初提出,此后由于加工技术的局限,一直到70年代才开始发展,而无油涡旋压缩机的技术出现更晚,由于其泄漏问题也限制了无油涡旋压缩机的发展。目前虽然涡旋压缩机已经占领了空调市场,无油涡旋压缩机技术仍然不够成熟,国内生产无油涡旋压缩机的厂家也不多。然而由于涡旋压缩机的众多优点,其发展的前景还是比较好的,不过目前对于涡旋压缩机的研究并不多见,这次做无油涡旋压缩机毕业设计就遇到了很多问题,设

涡旋压缩机最早诞生于1905年, 由法国工程师Leon Creux发明的,由于加工技术的局限性,80年代初才开始批量生产。70年代开始,由于能源危机的加剧和高精度数控铣床的出现,为涡旋机械的发展带来了机遇。

空气压缩机是一行业覆盖面非常广的通用设备,我国每年空气压缩机的总产量达500多亿人民币。而我国空压机行业生产水平一直处在较落后的水平,主要生产能力集中在传统的活塞式空压机,而近几年发展起来的螺杆式压缩机生产能力,也是以进口主机,整机国内组装的方式为主。

吸附式系统包括太阳能集热器、冷凝器、储液器、蒸发器和阀门。
