【技术实现步骤摘要】
一种防爆低温机组
本实用涉及一种制冷设备,具体涉及一种防爆低温机组。
技术介绍
低温机组是一种将常温的水通过冷水机的压缩机制冷到一定温度以强化冷却的机器,防爆低温机组,主要应用于石油、化工、医药、军工、机械等可燃性气体危险场所的制冷和降温。传统低温机组一般只是将机组置于比较空旷的场地上,因为没有特殊情况的限制,只是通过操作离机组较远的控制装置来控制,但是低温机组内部毕竟会产生高温高压,还是会有一些安全隐患的存在,特别是运用于特殊场所的低温机组,防爆性能是一个很重要的指标。而且传统低温机组只是单单通过一个闭环管路系统进行制冷而不会在外部设置水箱装置来增加设备的制冷效果,制冷效果相比较而言会有所不足。
