    Drier

    Hello All,

    I have a stupid question. I am working on a small dehumidifier. It is a flooded system. A 7000 BTU/hr Rotary Compressor is used. R22 is the refrigerant and cap tube is used as the metering device. In order to cut the price, some people suggest eliminating the drier from the system. As a refrigeration engineer, I have never designed any systems without driers. So I really do not have any ideas about this issue.

    Is it possible that a system works properly for a long time without the drier? If it is possible, what vacuum level should be reached before charging?

    Any inputs are welcome.

    Thanks
    Vincent
