well the question to my doubt is the following I have an air of 24000 btu brings 2 connectors for the manometer in each valve in which when placing the manometer the one of low mark 60 psi and the one of "high" mark 120 psi Well, out of curiosity, weld a service valve in the part of the bone condenser a little before the capillary and load it again with gas and in work the low one leaves it at 60 psi just as it was and the servisio valve that I placed new before the capillary mark 350 psi my question is this how much is the nominal pressure of the evaporator at work note this air and the capillary has been changed GREETINGS

The high pressure is 350 and low 65 for r22
Something you do not mention is the type of refrigerant that it carries, Many think that it is obvious and do not mention it, they take it for granted but the truth we can only be guided by the information provided by the person asking, we can not guess or assume anything

You are right Electomaq. For the low I assumed it was R22a,. It is necessary to clarify what gas you use

Hi . There is something that you are not doing well or the capillary that you put is not the one that carries because there is no correspondence between the 2 pressures. At a suction of 60 psi the discharge should be at about 230 to 250 psi.
If it has 2 access valves I imagine it is a central air because the splits only have 1 valve. If so, why don't you take the pressure there?
The high pressure should not be taken very close to the capillary because it is a very unstable area, it must be about 25 cm at the condenser outlet.

if my curiosity is that which would be the nominal pressure in the discharge you doubt that if I took it in the second valve and in that it has a pressure of 120psi in the low 60 psi and where I put the valve has a pressure of 350 psi

The high pressure as I said should be at 230 to 250 psi. And there is no correspondence between the 2 pressures
Is it a split?
Tell me about team performance. Measure the thermal jump (air inlet temperature to the evaporator and air outlet to the room.)

the air works perfectly
I think they don't understand my doubt
and my doubt is the next to what pressure is the gas when it circulates through the condenser

As a principle, the high pressure line from the inlet to the condenser to the outlet must be the same, however a cooling process is taking place to convert the gas that the compressor expels into liquid, therefore it is a transfer zone of heat where pressures can be unstable. Therefore, when high pressure is to be checked, it must be at the condenser outlet
