At least I think it's new as several searchs of the whole forum have not produced any meaningful results! But I'm not sure where to post or whether we need a new forum or what so I may need re-directing.
I am investigating the performance of several swimming pool packaged heat pumps, mostly heating private pools. I have started to monitor their performance and find the results are very varied, even on supposedly identical units. So starting with what seems to be the worst unit we are going to check each one.
However finding meaningful data is proving difficult, label data only gives initial charge and low & high pressure v temperature curves. I am therefore keen to hear from anyone who can suggest how to establish if the units are performing properly and how we can readily establish if refrigerant etc needs adding. Most of the units run on R22 but what level of superheat might be expected on the hot gas from the compressor (This is the only pipe readily accessible without dismantling)
Here's hoping!
