技术领域
本实用新型涉及制冷系统，具体而言是一种橇装化制冷系统。
背景技术
天然气的液化通常在固定式液化工厂实现，作为天然气液化的重要环节，制冷系统也设置在固定式液化工厂里。多数非常规气气井资源有限，当其气竭时，固定式液化工厂因不能整体搬迁而面临两难的尴尬：拆散后运输到位再安装，耗费大量时间，还会造成损坏和报废；闲置起来也是浪费。另外，现有的制冷系统结构复杂、投资较大、占地面积大、运行成本高，对于煤层气、页岩气等非常规边际气田的液化不适用。因此，设计出一种结构简单、功能集中、整体移动方便并且能满足小型煤层气液化需求的橇装化制冷系统十分必要。
发明内容
本实用新型的目的就是提供一种结构简单、功能集中、整体移动方便并且能满足小型煤层气液化需求的橇装化制冷系统。
