Refrigerant R290

Introductions

R290, is refrigerant grade propane, a natural, or “not in kind”, refrigerant suitable for use in a range of refrigeration and air conditioning applications. The use of R290 is increasing due to its low environmental impact and excellent thermodynamic performance. It is non-toxic with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential). It is a flammable refrigerant and therefore not suitable for retrofitting existing fluorocarbon refrigerant systems.

Applications

R290 is mainly used to replace R22 and R502 refrigerants in cryogenic refrigeration equipment; since R290 is flammable, it is usually only used in cryogenic refrigeration equipment with less liquid charge, or as a component of low temperature mixed refrigerant; R290 Compatible with traditional lubricants.

  • Commercial Refrigeration:
    • Plug- Ins & Vending Machines
  • Industrial Refrigeration
  • Residential & Light Air Conditioning
  • Industrial/Commercial Air Conditioning DX Chillers

Handling & Storage

R290 refrigerant cylinder is a pressure vessel, and it is flammable and explosive. It should be kept away from fire, heat source and direct sunlight when stored. It is usually stored in a cool, dry and ventilated warehouse. It should be lightly loaded and unloaded during handling to prevent it. Accessories such as cylinders and valves are damaged.

R290制冷剂

产品概述

R290制冷剂,别名R-290,中文名称丙烷,英文名称propane,化学式C3H8。R290属于碳氢制冷剂——对臭氧层完全没有破坏,并且温室效应亦非常小,实属当今最环保的制冷剂,从环保的角度来讲,全世界几乎所有国家对于R290制冷剂在新制冷设备上的初装,以及售后维修过程中的使用均没有限制。

产品用途

R290主要用于替代R22、R502制冷剂使用在低温制冷设备中;由于R290易燃,通常只用于充液量较少的低温制冷设备中,或者作为低温混配冷媒的一种组分;R290与传统的润滑油兼容。

储存运输

R290制冷剂钢瓶为带压容器,且易燃易爆,储存时应远离火种、热源、避免阳光直接曝晒,通常储放于阴凉、干燥和通风的仓库内;搬运时应轻装、轻卸,防止钢瓶以及阀门等附件破损。

配套冷冻油

R290制冷剂在不同设备、不同应用场所最终使用何种冷冻油,应遵照冷冻压缩机和制冷(空调)设备厂商的建议、或根据该制冷压缩机、制冷设备使用的具体情况来确定使用同等设计和技术员要求的冷冻机润滑油,即选用对等的冷冻机油。
