CXP
The Alfa Laval CXP is a compact condenser for fresh water applications that use HCFC or HFC refrigerants at medium and high pressures (30 - 45 barg). Capacity range 5 - 150 kW. PED/CE, EAC, SELO, DNV and other major marine approvals are available.
Alfa Laval CXP series – for applications using R404 refrigerants
For lower capacity requirements, the Alfa Laval CXP series is ideal as it is specially designed to use smaller tubing for up to 150 kW. This series is suitable for (among others) R404 refrigerants.
Options
- ASME, EAC, SELO, DNV and other major marine approvals available upon request
- Mounting feet
- Sight glass
- Desuperheater version
Benefits
- Compact design vs equivalent products in the market
- Flexibility: modular header for 2 and 4 passes
- Performance guarantee by Alfa Laval lab test
- Configurable online: contact Alfa Laval local sales organization to get the login
运行原理
所有淡水冷凝器都是壳管式热交换器，壳侧流过一次流体（通常是两相 HFC 制冷剂），管侧流过二次流体（纯水或添加了防冻盐水的水）。
淡水冷凝器被设计为冷却系统中的一个组件，由压缩机、冷凝器、蒸发器和膨胀阀组成。两相制冷剂在高温高压下以蒸汽形式从压缩机进入冷凝器。
制冷剂从外壳上部的连接处进入冷凝器，并通过撞击板分布在整个外壳上。高压热蒸汽制冷剂与输送冷却水的管子的增强表面接触，导致冷凝。
冷凝过程结束后，制冷剂略微过冷，以避免蒸汽气泡进入膨胀阀。由于采用了高性能管道，这种自由冷凝过程可确保较低的冷凝温度，从而提高冷却系统的效率。
冷却水源可以是冷却塔、干式冷却器、水井、河流、湖泊或工业流程。在水源方面，我们设计了单通道、双通道或四通道结构的两对集管和垫片，以确保每种应用都能获得合适的水速和压降值。
