compressor question

[edsky]

my compressor right now is moisting/prespiring when my aircon is turned on..a friend of mine told me that it shouldnt be the case..dapat daw ang nagpapawis lang ay yun linya/tubo papasok ng unit & not the compressor itself..i've also noticed that the coolness of my aircon wasnt been the same as it was..btw my aircon was just been cleaned last month.
my question is - a) is it normal for a compressor to moist/prespire ?? b) if not what could been the culprit?? c) what are the parts of my a/c that is need to be monitored??

my ride is a mits-advie

tia..all you inputs will be appreciated

hi sir.

just my personal opinion- if after cleaning ng aircon and still you are not quite satisfied with the cabin temp, cguro sir di lang maayos ang pagkakagawa or paglilinis ng car a/c mo? pde rin kulang ang refrigerant or worst fake ang ginamit. sir, naitanong mo ba sa a/c technician kung ok pa ang pump/vacuum ng compressor mo ? normal reading should be 35-40 psi (lower in other car model) sa low side ng cooling system and 150-200psi sa h-side (little higher is some model) higher manifold reading between this range could indicate compressor malfunction.

thanks sir audio_hunter actually iisa lang po yun a\c tech na nagma-maintain ng car a\c ko...talagang nagtaka lang ako ngayun dahil nag bago yun lamig nya, compare before...so i also assumed na di rin fake yun gamit nya na refrigerant...pwede po sigurong kulang..yun mga setting's lang po na mention nyo ang di ko alam, as in kamote po ako sa a\c , kaya those parameter inputs of yours are so valuable for me...siguro this coming weekend puntahan ko, para matanung ko sa kanya yun mga setting na nabanggit nyo..salamat po ulit boss

edsky,
if I may give some inputs:
First, di dapat mag moist ang compressor. Moisture occurs when a certain area is colder than dew point of the air. My suspect, freon is leaking out of the compressor. Maybe the seal is worn out or loose. Yun lang naiisip ko na malamig na pwedeng mag-cause ng moisture ng compressor.
Second, "...dapat daw ang nagpapawis lang ay yun linya/tubo papasok ng unit & not the compressor itself." - This is CORRECT.
Lastly, just a hunch, kaya humina ang aircon sa paglamig its because freon has leaked.
Goodluck on the fix.

New a/c compressor does not perspire,but since its a workhorse and responsible in removing hot air inside your car cabin, after years of faithful service soon it will perspire/moist. An indication to its master(car owner) to save enough budget for its replacement. Refrigerant leak will give you cold cabin for days or a week, but suddenly your a/c will not work do to low refrigerant. Shaft seal refrigerant leak is the worst leak of all, most of the refrigerant will be lost in 1 day.

I am no car a/c expert, I just based my suggestions through my personal experience w/ my car /ac and through hundreds of forum pages that I've read from the internet.

....perspire,but since its a workhorse and responsible in removing hot air inside your car cabin, after years of faithful service soon it will perspire/moist. ...

Then why does it moist then? Moisture happens when there's an area whose temperature is below the dew point temp of the air, thus the moisture. Then the compressor is cold while it shouldn't be cold. Why? The compressor is merely a pump. Its a to pump the freon to a compressed state & heat it up. Then as it is heated when compressed the heat is rejected thru the condenser (in front of the radiator), then expanded again for evaporation (at the cooling coils/eveaporator).

....Shaft seal refrigerant leak is the worst leak of all, most of the refrigerant will be lost in 1 day.

Do you know the degree of leak for you to know that the freon can be gone in 1 day?

I'm no expert either. I just happen to have experience working in one of the biggest airconditioning manufacturers in the world with a BS degree in Engineering.

Cheers!
