    some question



    hello all really missed you
    and pardon me for long time no contact
    due to several issue
    non stable country
    and Spinal disc herniation i had
    in addition to Myorrhexis
    in both arm
    and Migraine


    my question
    here i saw many add ***** 134 to r22 split
    when charging and many assume it will rise efficiency which i doubt
    also inverter entered iraqi market widely 2 or 3 years ago

    LG GREE COPIED GENERAL
    GE DAIKIN PANASONIC
    AND LITTLE NON INVERTER


    MOST OF COMPANY ADD MORE LAYER TO CONDENSOR OUTDOOR TO WITHSTAND TEMP WHICH CAN REACH 55C
    410A CLASSIC SPLIT
    COOLING IS NOT GOOD LIKE R22 ITS


    Power consists not in being able to strike another but in being able to control oneself when anger arises

    Re: some question

    Hi Kefah, good to hear from you.

    Adding R134a to R22 to raise efficiency is a new one to me. Sounds like someone had a bottle of refrigerant they wanted to use up!

    We haven't had R22 units in England for around 15 years now, it's all R410A but now R32 is coming in to replace it.
    Many people say R410A units don't cool as well as R22. That might be because and R410A running from an inverter can evaporate at variable temperatures (i.e. higher or lower suction pressure depending on compressor speed) whereas fixed speed R22 would just cool as much as the components would allow.
    Pressures as I'm sure you've seen are much higher in R410A so in ambients of 55*C the compressor will take a right pounding and as you say don't help with cooling.

    Hope you manage to get back to fitness and keep safe,
    Andy.
    Health and safety first..........unless I'm in a hurry.

    Re: some question

    thanks for info
    another not so good method very common currently for maintaining compressor run at extreme high temp
    is connecting capillary to compressor suction it will keep compressor cooler but decrease cooling efficiency
