Every flammable refrigerant I've seen is usually in a completely sealed system. There is no way to maintain them unless you completely vent the system and add ports yourself, manufacturers don't seem to want the liability and many governments force the issue by code anyways.
- londons_explore 4y agoYou typically need to completely vent the system for any maintenance on a refrigeration system anyway, if only for the fact it is important to weigh the amount of refrigerant (too much and you could get slugging, which is very expensive to fix). I think lack of ports is simply to save money - in the factory it's just as easy to fill once and crimp the system closed.

For larger systems this is not true. You're typically going to have a receiver and a valve you can use to store the charge entirely in the receiver. Then you can work on the system without having to dump or capture that charge. It also allows you to have additional cooling circuits, so you're starting to see this incorporated into smaller commercial designs for the additional cooling efficiency. > I think lack of ports is simply to save money They're required to be hermetically sealed in the US by IEC and in most Pacific Island countries by law where they're more commonly used in residential applications.
