Had a customer who asked me to look at his coldroom. He said many engineers have looked and nothing ever lasted. Told me his water bill is thru the roof. Had a quick look on the weekend. First thing I noticed was the Evap had r22 written on it and in poor condition, I can see the last guy who looked at it thought duct tape was the solution to all problems.
Anyway moving on, he showed me where the condensing unit was, you could hear the water going in and back out to the drain.
I said best bet is to upgrade to a current gas r404a/r134a.
Went back and had better look today, Evap has seen better days, measured up the room which is 22m3. Tried to have a better look and the condensing unit, wasn't able to get much details off it apart from thermofrostcyro and 97date. I could see the heat exchanger but unlike other systems I have worked on its piped mains cold water into the top and from the bottom straight to drain. No outdoor heat exchanger. Just straight to drain.
I don't think it's worth trying to fit a outdoor heat exchanger with the r22 ban around the corner.
Questions are how has this system worked, if ever?
If you want to fit a water cooled outdoor part, where do you get them from?
Or do I suggest I go to hawco and purchase a coldroom kit and start a fresh?
