What should be done to reduce refrigerant loss from a purge unit on a CFC-11 chiller?
Leak test and repair the chiller.
Why do chillers using CFC-11 and HCFC-123 require purge units?
These refrigerants have higher boiling points than say R12 or R22. Thus when a machine using them operates the low side will run in a vacuum. So any low side leak points will suck in air rather than leak refrigerant out. A purge unit constantly samples the condenser gas and removes the air and water vapor which has been pulled in at these leaking points and periodically releases them to atmosphere while it condenses any refrigerant vapor picked up in the sample mix to a liquid and returns it to the machine.
Can nitrogen be used to purge gas pipes before welding?
Yes, and No, Nitrogen can be used to purge gas lines prior to welding, but the correct answer depends on several things, mainly, your welding application. A significant amount of resistance welding applications use N2 as a suitable environment for welding. Other applications use N2 as a purge gas, and then purge the N2 with the process gas. That said, if you were going to be using a different inert gas (Argon, Helium, Xenon, etc.) to provide the actual the actual shield for the weld, then you would still need to displace (purge) the N2 from the lines. The last statement leads to the question of; if you are going to have to purge the lines anyway, why do it twice? The answer to this question is pretty basic. Nitrogen is cheap. If you had to purge a lot of lines, or a large volume of space, you would rather use N2 to drive out the Oxygen and lower the dew point (moisture). Using one of the other welding gases would cost about ten times as much to perform the operation.
Should you insulate swimming pool pipes underground?
I see no reason why you would insulate them. When you close your pool for winter you will purge (empty) your pump and pipes. The water in the pool would freeze long before the water will in the pipes under ground.
How do you purge water pipes for the winter?
The best way to purge water from pipes for the winter is to open the tap for about 24 hours. It is also a good idea to install frost proof hydrants on all outside outlets.
What are uses for helium?
According to Helium.com, "It is used in low-temperature cooling systems and pressure, lighter-than-air objects and purge systems".
Is helium valuable what industries use it?
Yes, helium is valuable due to its unique properties such as being non-reactive, lightweight, and having a low boiling point. Industries that use helium include aerospace for filling balloons and airships, electronics for cooling purposes, healthcare for MRI machines, and research laboratories for various experiments.
What does purged mean?
A purge is an act of purging, or a cleansing of pipes. To purge means to clean thoroughly, or to free from guilt or sin.
