OK - I see where you are coming from now. But I don't think that it would work. The best way (not to mention the easiest...) is always going to be to raise the temp of the mirror to above the dewpoint, rather than cooling the surrounding air below the temp of the mirror. Because as you cool the air, it will be able to hold less water vapour, making dew formation more likely
