Condensers - The Liquid ProducersWritten by Thomas Yoon

Actually that's how heat is removed from air-conditioned space. The heat from a building is transferred to refrigerant through cooling coils. This heat is then transferred to condenser. The heat is then transferred to cooling medium. The cooling medium finally transfers heat to admosphere or to sea.
Of course, there are many other components in between to make system work.

REMOVING YOUR OLD SLIDING GLASS DOORWritten by John Rocco
Continued from page 1
So, now you have to remove side jambs. You want to do this without damaging exterior material that surrounds door frame. Take a heavy chisel and pound it into crack between frame and exterior material, whether it's stucco, siding, etc. Start at bottom 6 inches first. What you are trying to do is pull nail fin away from nails holding it in place. So, once chisel is pounded through metal frame, pry away from side wall. The heavier and longer chisel, more leverage you will have. You will hear frame "pop" free of nail. There will be several nails holding each jamb in place, so you want to start at bottom and work your way to top corner. Once you get bottom third loose, many times you can grab jamb with both hands and pull rest of nails free as you go up. When you get to top corner, work jamb free. Do both jambs, then do top. Sometimes top has no nails, or just one in center, so it will come down pretty easily. Be sure to wear safety glasses and a dust mask when doing this job, especially when removing top header.
At this point you are ready to install new door. The installation procedure is slightly different, depending on whether you're installing a retrofit style frame or a replacement frame. We will discuss both procedures next week.
