Find loss of split refrigerant

Hello people, a customer calls me because his split runs out of coolant, when I go I don't see losses in the nuts that are in sight, I took it, I made it empty separately (evaporator and condenser) and I check that it contains the vacuum . Consultation: if it was punctured, would it go to 0 if or if the manometer?

Instead of the vacuum try to get air to raise its pressure and submerge it in a tank with water if there is perforation you will see the bubbles it may be a very small leak that takes too long to lose the vacuum

Hello fabi good night, I look for a loss I proceed as follows, the first thing I do is look at what you have used, if 22 or 410 and if the equipment is cold hot, at what temperature peaks my province or locality arrives in summer, hence, I look at the refrigerant slider table that downloads from the play store, there goes the example if it is 22 and in my province I have temperatures of 45 degrees I would have a pressure of 233 psi with equipment stopped, I particularly inflate it with 300 psi of nitrogen and immerse it in a pool with water and so you can find your loss. Greetings. I hope you have understood me

Comes a product that is used to detect the failures that are thrown into the system with a needle and then put pressure on it and with UV glasses the leak can be seen

How expensive is the UV flashlight but then you can buy the syringe alone and it lasts a lot depending on the route or meters of the circuit's spout.

The economic solution is to look for the tutorials on youtube that teach you how to make UV flashlights, buy yellow lenses at the hardware store and only buy the syringe in replacement refrigeration houses.

Hi Nachito: Sorry to differ with the use of these products, but they often cover the capillaries, this type of products is not designed for these equipment only for air or automotive cooling, so it is my negative vote. Because such products are NOT used for equipment such as the one in the consultation. It is not to argue and I do it with respect. Thank you

I recommended the product because I used it in equipment with R410a without problems and at the end of the procedure I perform a scan to avoid leaving product residue or obstructions. Another device that also comes the gas leak detector by probe. I also leave link https://articulo.mercadolibre.com.ar/MLA-663513622-detector-de-fuga-de-gas-refrigerante-wjl-6000-r-410-r-22-_JM

Hi Fabi: First point to keep in mind, if you work with R-410a or with R-22. If it is with R-410a and was completely without refrigerant, the ideal is to change the lubricant of the MC, this I say because it quickly takes moisture, then the MC is acidified and deteriorated. Then pressurize according to the equipment manual, with nitrogen (some ask for 400 psi and others 600 psi) and look for other losses apart from those that you could see with the naked eye, the best is soapy water or an immersion bat like gummies (for the latter you have to disassemble everything electric and leave only evaporator and condenser free) This is a job that takes time, if you leave it pressurized from one day to another better, (always with the high pressure gauge to not de-calibrate or break the low) Luck, comment your results.

Hello, if it was punctured, yes, it goes to zero fast, but if it is a micro pore, it can take a long time (even days), to notice the vacuum loss. To rule out possible punctures, the ideal is to do it with positive pressure using nitrogen.
