    Thanks. But I dont need Google to explain this.

    May I ask you a question sir, do you know what will happen to the "freon" if it will leak somewhere in the cooling system ? will that part be cold as if the "freon" is leaking thru it? i'll tell you sir, it will not. what you can see is just a stain of leaked freon.

    [SIZE=4]YES it will be cold & there will be frosting at worst if the leak is too much! As to the stain. There's no stain, because its gas. How can it stain metal or rubber? Kaya nga technician use bubbles to detect a leak. Maybe the stain you are talking about is caused by the compressor oil if it gets out with the freon on certain cases.
    Ganito, next time you have your car A/C cleaned, yung freon na pasisingawin thrust it to a metal surface, then touch it. Tell me kung malimig.

    "....heat is not rejected through a/c condenser in front of your car and radiator but it merely lowers down the pressure as for the temperature of liquefied refrigerant

    [SIZE=4]Are you 100% sure that the condenser infront of the car is just to "MERELY" lower the pressure/temperature & heat is not rejected? Are you willing to bet your car on that? I am!
    Check the link pheztie posted.
    ps: den1106 (above) wants to know your source on the condenser
    I need not explain more.
    The 2 guys above pheztie & den1106 are boggled by your explanation.

    [/SIZE]"then expanded again for evaporation (at the cooling coils/eveaporator). "--- correction sir it is not "expanded again for evaporation" it is expanded as it passes through TXV or an orifice that regulates the refrigerant flow into the evaporator.

    [SIZE=4]Pheztie above is kind enough to send us a (link)diagram. Look what comes after the condenser. Its the expansion valve. The orifice you are talking about is called expansion valve & leads to the evaporator.
    [/SIZE]

    We're both members of this forum/group since I believed, we both want to help others (not to mislead them) and we're both eager to explore and learn new things that we merely knew.

    [SIZE=4]I dont mislead them. I comment when i know my stuff, modesty aside.
    [/SIZE]
    Cheers also to you sir..
    [SIZE=4]Cheers & peace![/SIZE]

    sir hindi naman natin kailangan magaway dito..pero mas maganda siguro kung plain explaination lang sagutin natin..yung simpleng sagot lang..kaya nag moist ang compressor DAHIL ANG SYTEM AY MALANGIS KUNG HINDI QUALIFIED A/C TECH O HINDI PA BIHASA SA LINYA NYA ay kadalasang ganyan ang nagiging problema..sa expansion valve naman papaano magkakaroon ng evaporation sa loob kung restricted ang flow ng freon..ok peace men..boss gusto mo sample natin..kahit parts lang ang babayaran mu ala ng labor..

    Ano po kayang dahilan bakit "nagmo-moist" ang compressor kung malangis ang system.

    gd day, im no expert too, curious lang po ako.

    may i ask kung yung buong compressor ang nag momoist o sa may portion lang ng linya papunta sa evap? likewise, yung linya ba papunta evap nagyeyelo o moist lang din? ty

    sir gawin nalang nating simple..pag cloged ang expansion valve sa langis merong restriction ang comp sa pagbomba..kaya yung binobomba ng comp babalik sa compressor..subukan mong i rev pa at buhusan ng tubig makikita mong papawisan ng husto ang compressor hanggang sa katawan nya..dagdag ko lang kabaligtaran naman sa kulang ng langis minsa nagbaback pressure ang compresor..umiinit pa o pag binuhusan ng tubig ang compresor makikita mong kumukulo ang binuhos na tubig..salamat at sana nakatulong ako

    sir hindi ko sa buong compressor makikita nyo na sa suction o sa dinadaluyan ng freon hanggang sa pinalabasan ng freon.sir nagmomoist talaga ang tubo lalo na suction..pero hindi kinakailangan na magyelo ito..maaring defective na ang thermostat..sa ibang kaso ang hot line tube ang nagyeyelo katulaod ng nissan safari dahil nagyeyelo naman ay kulang ng freon..

    Sorry, hindi ko pa rin nagets yung paliwanag mo dito:

    1. pag cloged ang expansion valve sa langis merong restriction ang comp sa pagbomba..kaya yung binobomba ng comp babalik sa compressor..

    Paano nagki-create ng restriction yung sobrang langis sa expansion valve? At saka ano yung binobomba ng compressor na sabi mo babalik uli sa compressor.

    2. subukan mong i rev pa at buhusan ng tubig makikita mong papawisan ng husto ang compressor hanggang sa katawan nya..

    Alin ang bubuhusan ng tubig, yung compressor?

    3. .dagdag ko lang kabaligtaran naman sa kulang ng langis minsa nagbaback pressure ang compresor..umiinit pa o pag binuhusan ng tubig ang compresor makikita mong kumukulo ang binuhos na tubig..salamat at sana nakatulong ako

    Could you explain more on this?

    Thanks

    1.high temp low side na freon na galing sa compressor..sa loob ng expansion valve merong parts doon na parang karayom..pag maraming langis na kasama ang freon magakakaroon ng restriction sa pagpasok sa valve.. ang buuhusan mo yung compressor..at yung huli explain kolang papano nanam kung kulang ng langis..email ko gorionikoy*yahoo.com..09282946925..para mapag usapan ng maayos..

    Sorry uli! Hindi ko pa rin magets!

    Dito mo na lang post yung iba mo pang expalanation, para rin naman sa kapakanan nung iba.

    hahaha..sir tutal pwede mo na ring i research kung kung papaano ang nangyayari sa loob ng car aircon..ang cycle o loop ng freon..ok na ho iyun..
