F-Gas failing again

Five years ago, I had the unenviable position of being at a meeting discussing what to do about the F-Gas Regulation.

As you will all know ive recently decided to branch out on my own and have started a new venture as a dedicated heat pump distributer.

One of my first jobs when I moved into our new premise was to upgrade the Aircon. Installed in place was an ancient non inverter wall mounted system. As is always the way when leasing a new building the previous occupants have to make good before the new owners can move in.

So before I moved in the old Aircon unit had to be serviced. An engineer, (I use this term loosely) attended site and found the unit had no gas in it. He decided that because the unit had been manufactured with R22 the time had come to retrofit the beast with R59.

The original unit had 1.5kg of R22 in it, it was replaced with 3.7kg of the new gas, surely this can’t be right but what do I know ive always put the right refrigerant in everything I worked on. The unit was tested and the engineer signed it off.

Today I pumped it down and ripped it out, the plan is to sell it on eBay. As I disconnected the pipe work I found them covered in oil, the best bit was I found the suction line (the big pipe) was loose, it appears the flare nut was cracked. So in conclusion the unit had a leak, it was allegedly repaired and a huge quantity of new refrigerant added. It leaked again as the leak was never found or solved and now ive saved the planet by pumping it down and removing it from service.

So how will I cool my new office now? Easy I will be using a Samsung EHS heat pump system with optional fan coils, the only heat pump available which can have air conditioning units connected to it.
