Hello everybody, how are you doing???? I have an air that was given to me and I want to fix it for my own use, but I got into a concern, that air is with R22 and the compressor is broken. What would happen if I change compressor for one of R410 ??? Could you use the same hair? or evaporator condenser itself ??? Would the pressure of the R410 withstand the spout of said air? Diameter and capillary length in case of change ??? This is by way of concern in case someone has already made a change of this style and according to the favorable results or not ... Maybe someone with a lot of experience could shed light on these questions, and based on that you may do so by sharing the results . Greetings thank you.

I understand that you have to modify the capillary pressure drop, the rest can work the same.

Hi. Although the 410a works with twice the pressure of the r22a you should not worry about it. The lines can withstand those pressures and it is not by theory but I have seen many such adaptations and on occasion I have put evaporators and condensers of r22a equipment to others that work with 410a. What is certain is that you must change the capillary. You can use a 0.49 HOW TO DO IT You put an access valve at the top of the compressor to put the manifold there and into the tube of that valve welded the capillary of about 2 meters Start the compressor with manifold on the valve and it will be giving you the pressure drop that you should leave at 65psi with the r410a gas If when you measure it it gives you over 65 psi you cut the capillary pieces until you achieve that pressure. You will see that when you start the pressure it will start to rise, you must wait for the manifold needle to stall. Every time you are going to cut you stop the compressor so that it does not heat much and do not forget after the cut check that the capillary is open inside

Hi NG thanks for your report and how to achieve capillary measurement just a question ??? we talk about running the compressor to calculate the capillary but with r410 gas or with the air that the compressor will suck through the suction ??? Thanks to everyone for your replies

With compressor air.

When you change gas, you must clean the pipe well and make it empty, the oil must be for each type of gas, but it reacts chemically and covers the capillaries,
