what can cause a system which has suction 26PSI discharge 195 psi and 28F at the end of tvx to go to > 60 F when you add refrigerant to it that give suction 44 psi and discharge 225 psi

Your question doesn't make any sense. Try again.

Who gives you this "academic" questions.
Maybe, if you present them in original form, you end up with right answers much faster.

I restart the system but it stay at 52F
i try to be short but it's the original form

where you have 52F??? evap?? condensor outside ?? before TEV or after ??? more info please

after TEV. Condenser outside . subcooling 3.33F. superheat -5F

For a proper evaluation, we need the following information:

Low side:

Evap air in temp
Evap air out temp
Saturated suction temp (SST) converted from pressure
Suction line temp at evap outlet

High side:

Cond air in temp
Cond air out temp
Saturated condensing temp (SCT) converted from pressure
Liquid line temp at receiver outlet

This is a kind of chiller (pool) but water is not flow out.
Without load on it we find
Liquid line 96 F
Suction line 65 F
Condenser 89.6 F
Climate 93.2 F

Saturated Suction 5.2 F
Saturated condensing 101 F

what is the application?
whats the gas?

Cond air in temp?
Cond air out temp?

What is "condenser" and "climate"?
What you mean by "but water is not flow out"?
If "climate" is ambient air temperature and "condenser" is condenser air out temperature, than that numbers doesn't make sense!
What you mean "without load"?

gas r22

water chiler

climate temp is the temp arount the system

condenser temp is the temp i found on the oposite face of the conderser blower

Describe evaporator!

Why I have feeling like I am pulling informations you hesitate to give?
Or it is language barrier?

the blower of the condenser is an aspiration one

normaly the load is the water i want to cool . when it's empty i said it is without load

Saturated Suction 5.2 F
Saturated condensing 101 F

101F minus 96F = 5F subcooling.

Add refrigerant until the subcooling is 15F.

Then take all of these measurements again... with load.

Sorry, aspiration condenser is something I never heard or saw.

How you move water around evaporator, or it moves naturally?

have you got load on the cooler?
i assume that you have a good water flow.
