  • 压缩机怎么选型?

    本站编辑:高伦制冷发布日期:2022-05-17 09:41 浏览次数:

    在制冷系统的设计中,首先需要面对的是压缩机的选型, 对于刚入行的同行来说压缩机选型有点难度,其实只要掌握了技巧,关于压缩机的选型是最简单的。

    在实际的设计中,压缩机的选型首先需要确定采用什么形式的,是转子压缩机、涡旋式压缩机还是活塞式压缩机?或者是螺杆式离心式压缩机?

    一般的小型制冷装置中,比如家用空调、小型除湿机等,大部分采用的转子压缩机;稍微大一点的制冷系统,风冷热泵、风冷冷热水机组,采用的就是涡旋压缩机了;大一点的制冷系统,冷库制冷机组,采用的就是小的活塞压缩机了;再往上大的系统,可以考虑采用螺杆式或者离心式压缩机了。

    确认好了用什么形式的压缩机,下一步就是考虑下用什么品牌的压缩机了。关于品牌的选择,主要考虑设计习惯和成本;

    在家用空调领域,格力一般采用的是凌达压缩机、美的是GMCC压缩机、奥克斯或者其他品牌的采用的是海立、瑞智、三洋等品牌的压缩机;

    在涡旋式压缩机的领域,通常采用丹佛斯、谷轮等品牌的压缩机,当然现在很多厂家为了节约成本,也有再采用英华特压缩机的厂家;

    关于活塞压缩机,通常就是丹佛斯、比泽尔、博客、泰康等压缩机了。

    In the design of refrigeration system, the first thing we need to face is the selection of compressor. For the new peers, the selection of compressor is a little difficult. In fact, as long as we master the skills, the selection of compressor is the simplest.

    In the actual design, the selection of compressor first needs to determine what form to adopt, whether it is rotor compressor, scroll compressor or piston compressor? Or screw centrifugal compressor?

    In general small refrigeration devices, such as household air conditioners and small dehumidifiers, most of them use rotor compressors; A slightly larger refrigeration system, air-cooled heat pump and air-cooled hot water unit, adopts scroll compressor; A larger refrigeration system, the refrigeration unit of the cold storage, uses a small piston compressor; For larger systems, screw or centrifugal compressors can be considered.

    After confirming the form of compressor, the next step is to consider what brand of compressor to use. As for the choice of brand, the design habit and cost are mainly considered;

    In the field of household air conditioning, Gree generally adopts Lingda compressor, Midea GMCC compressor, Oaks or other brands, and Haili, Ruizhi, Sanyo and other brands;

    In the field of scroll compressors, compressors of Danfoss, GuLun and other brands are usually used. Of course, many manufacturers also use yinghuate compressors in order to save costs;

    Piston compressors are usually Danfoss, bizel, blog, Taikang and other compressors.
