scroll compressors

[spooky]

4 ton carrier scroll compressor very very noisy, I had a owwned a scroll compressor but not that noisy . Unit does cool house down , suction return to compr. 55 degr.

Pressure means nothing, make sure it's correctly charged and not slugging liquid and then put a sound -deadening blanket over it if it doesn't already have one.

It does not have a sound deading blanket . I will check for slugging liquid .

you can put a sound blanket around the sides of the scroll but do not cover it

If its a Copeland Scroll then Copeland makes a custom blanket for it.

Shoot it. I've never seen a blanket make even a slight difference in noise reduction.

The first thing I did to my YRA heat pump 10 yrs. ago was pull that heat trap off the scroll.

Sound blankets do reduce noise but if you have a nosiy compressor to start with they wont do much. They reduce the hum from the compressor. They are not a heat trap since the compressor is cooled by refrigerant not air. Airfow around a compressor has no effect on cooling, otherwise the compressors would have fins like the head of a motorcycle.

The real problem needs to be addressed which may be charge related, airflow related, oil return related, non condensibles or a damaged compressor. Most often the compressor is changed out of ignorance but the noise returns because the real problem was never resolved and by replacing the compressor inadvertantly the non-condensibles issue gets taken care of and the oil is now doubled in the system which allows the poorly run refrigerant lines which trap oil to now flow it.

Self delete. Not worth my time.
