一个制冷系统能否充分发挥它的设计容量并安全可靠地连续运行,冷剂管道的正确设计与施工是一个很重要的因素。但是实际上,这一方面却往往最易为人们所忽视。管道的设计和安装,是指管径的确定、管道的安装走向、坡向、管道附件安装等。氟利昂制冷系统管道设计应考虑的因素为:防止发生湿冲程;润滑油的循环及冷剂管路的设计;管路压力损失及管径的选择。一、防止发生湿冲程液态冷剂或大量润滑油进入压缩机,可能会引起湿冲程导致严重事故。正确设计与
Whether a refrigeration system can give full play to its design capacity and continue to operate safely and reliably, the correct design and construction of refrigerant pipelines is a very important factor. However, in fact, this aspect is often the most easily ignored by people. The design and installation of pipelines refers to the determination of pipe diameters, the installation direction of pipelines, the orientation of slopes, and the installation of pipeline accessories. The factors that should be taken into account in the design of the Freon refrigeration system piping are: the prevention of wet stroke; the circulation of the lubricant and the design of the coolant line; the pressure loss of the line and the choice of the pipe diameter. First, to prevent the occurrence of wet-stroke liquid coolant or a lot of lubricating oil into the compressor, may cause wet stroke leading to serious accidents. Correct design and
