WHAT ARE YOU DOING TODAY - WAYDT (PICS)
-
I've been on a new project for about a month. This one's got a bit of refrigerant piping to it. In recent years, mechanical press fittings have become the norm for connecting pipe. But, there are branch fittings here that require something else. So, today, I get to braze…..
I love brazing. It's welding, without all the bright lights and smoke.

Do you purge with OFN to stop the oxidisation on the inside?

Do you purge with OFN to stop the oxidisation on the inside?
Yes. You wouldn't want much of that in the system. The filter drier will pick up any that may occur, if there happens to be an inadequate purge during a braze. But, they're not meant to clean up significant amounts. Having to replace a filter in a newly charged system is big no-no. It's quite likely, I'd never be allowed to braze again, if that happened.

Whats the sytem your working on, VRV, Chiller, Split? (I'm an a/c guy)

(I'm an a/c guy)
I guess I offered more of an explanation than necessary, then.
Being that, the majority of my work is usually centered around hydronic heating systems, you likely have more knowledge.It is a VRF system. There are 20 Mitsubishi units throughout the building, mainly in electrical service rooms. There is also a data center, which will have 4 CRACs on a separate system.

A day out at a cool, beautiful place one hours drive and a short ferry trip away from where I live. It is a preserved trading post of enormous local and national importance in the 1800’s on a remote peninsula. The name of the place is Kjerringøy which loosely translated means “Bitch Island”.
We had friends visiting and took them for a visit. 11C is classic north Norwegian summer weather and in classic north Norwegian style the kids saw water and a beach and got stuck in, temperature be damned.

Ba dum dum.

“Bitch Island”.
Sounds ominous –- but looks delightful

“Bitch Island”.
It is a bit of a dishonest translation to be fair. The word “kjerring” is old but more recently has been used to mean bitch. Originally it was a neutral vernacular term for a wife, a bit like “my old lady” in American vernacular. It was become increasingly negative to imply traits like being a woman who is a nag, hard, mean, strict, or cruel to her husband.
The probable reason for the name is that originally Kjerringøy was a community run by women as the men were at sea fishing or on trading journeys. Many would not come back from such dangerous activity, leaving the farming, trading and so one to a steadily growing female population.
