Back in the day, people used nasty refrigerants which damaged the ozone layer, including R11, R12, R22 etc.
Since the early 1990s we in Europe have phased these gases out – as I am sure your aware. The last of them, R22, is on its way out as we speak.
What worries me is although we are driving these gases out of existence in Europe it appears that other countries are not doing there bit.
We were recently asked to replace a big American chiller here in the UK. It was an R22 machine and little was known about it, weirdly there was very little on the web about this unit. Generally, if you type any model number into google you can get some information on any machine. After many hours of research we finally tracked down the information we needed to offer a suitable alternative.
What was surprising was the stuff we found while searching. It appears that second hand air-conditioning plant is not generally sold on eBay and as far as I am aware there is no classic air-conditioning magazine available yet (I am thinking of starting this).
We did however come across a website selling all manor of kit www.ippe.com. This company sells anything which is big, second hand and industrial. If you search for chillers or click here. There are some real dinosaurs and some scary kit.
Who wants to buy a 11000 CFM r11 centrifugal compressor the size of a bus? And if you do, where would you get the gas?
I can only assume that whoever buys this kind of kit can also buy the gas, I would like to know who’s supplying this stuff. Maybe we Europeans should have a word with their governments and ask them if they would like to join us in scrapping these gases as well.
