Good afternoon, the truth is that my papers were burned so I turn to someone who can and has the vondad to help me, the problem is the following: I have a cold center that works with R22, in which I have a discharge pressure of 250 PSI and about 49 ºC at the entrance of the capacitor and about 30 º C at the exit, because of the symptoms I think what it has is air in the system, I am purging through a siphon but I do not get improvements. the question is I'm misdiagnosing? It is worth clarifying that I do not have liquid in the hall ... and the plant does not perform..

If your doubt is that there is air in the circuit, the best option is to unload everything, vacuum and recharge.

from now on thank you very much and if what I did was exactly that, only they did not give me too much time to empty since it is a bakery plant and the machine stop means stopping the production, then vent as much as I could and reload, since it is a cold plant of 200 Hp simple stage but anyway thank you.

Uff!! ... I think you made the mistake of accepting to be controlled for the time needed to make a good empty, because a 200hp equipment has to be a lot of coolant to eliminate due to a bad maneuver ... Although I admit that it is difficult to make the client understand the time and materials that must be invested to do a good job, ... there is no lack of the master who competes with you for less time and fewer materials, and the customer who buys with him.

I hope it does not cause you many problems because you will have to wait for the next failure.
