I'm relatively new at refrigeration. I have been working in the heating and a/c field for some time now. My question is, how do you determine what size cap tube to use on refrigeraters? And,how do you determine how many horsepower a compresser is? As I see,the 2 are relative to one another.
So,the compresser,ARE43C3-IAA is 1/3 hp? How did you find that information? And Thank you.
That information helps a lot. Now I can just go to my supco chart,and see what size and length cap tube I need for a medium temp application.
United Refrigeration catolog. In the compressor section.
Thank you very much. Where can I get that catolog?
What is the ambient temperature where the cooler is located ? Is the condenser coil clean ?
ambient temp in that area is around 75 degrees or so. problem is the compresser sits close to the ceiling and in that area it gets pretty hot. The coil is clean,I faithfully clean all the condensing coils on a monthy basis. With the old compressor in place,before it died, my suction pressure was about 45 to 50,and the head was closer to 200 to 225. That's why I'm confused as to why the pressures are so screwy now. Like I said,the unit does use R-22.
maybe you could cut a couple inches off the cap tube?
true knowledge exists in knowing that you know nothing.
[QUOTE=andy1154;12591501] I'm confused as to why the pressures are so screwy now.
Maybe before your charge was low and now your at correct charge. Do as supertek65 suggested and remove a few inches off the tube. I will almost always change the cap tube on a compressor change. Cheap insurance.
What is leading you toward the cap tube? Why cut it and not just change it?
You need to put the phone down and get back to work!
