Condensers - The Liquid Producers

Written by Thomas Yoon

Some people call them capacitors. Others call them condensers. These components store electrical charges.

Mechanical systems also have condensers. Condensers are found underneath steam turbines. Air-conditioning systems have condensers too.

How this name came about is a mystery to me. Perhaps it is becauserepparttar condenser isrepparttar 100085 place for converting vapor or gas into liquid - at least for mechanical systems.

So it is a kind of heat exchanger. What isrepparttar 100086 cooling medium?

For air-conditioning systems,repparttar 100087 most common cooling medium is water and air. The vapor to be cooled isrepparttar 100088 refrigerant. And you've guessed it... It changes hot refrigerant gas into liquid.

When it does that, heat energy is removed fromrepparttar 100089 refrigerant. The heat gets transferred torepparttar 100090 cooling medium.

Last week I explained how to measure your existing sliding glass door so you can orderrepparttar vinyl replacement door. This week I am going to go overrepparttar 100084 steps required to removerepparttar 100085 old sliding door before installingrepparttar 100086 new door.

First, you have to removerepparttar 100087 sliding panel andrepparttar 100088 stationary panel. The vast majority of doors out there haverepparttar 100089 sliding panel onrepparttar 100090 inside half ofrepparttar 100091 track, andrepparttar 100092 stationary panel is onrepparttar 100093 outside. Whateverrepparttar 100094 case in your particular door,repparttar 100095 outside panel has to come out first. To removerepparttar 100096 fixed panel, you need to removerepparttar 100097 sill cap that snaps intorepparttar 100098 bottom track and runs fromrepparttar 100099 fixed panel torepparttar 100100 side jamb whererepparttar 100101 sliding panel locks. Force a screwdriver intorepparttar 100102 crease and pryrepparttar 100103 cap up. Then, look for screws onrepparttar 100104 inside side jamb holdingrepparttar 100105 fixed panel in place. These screws prevent someone from prying uprepparttar 100106 sill cap and pulling outrepparttar 100107 fixed panel in order to gain entry intorepparttar 100108 home. In addition torepparttar 100109 side jamb, be sure to check acrossrepparttar 100110 top header and bottom track for screws there as well. Once allrepparttar 100111 screws have been removed, you need to pullrepparttar 100112 fixed panel away fromrepparttar 100113 side jamb. You can start by simply grabbingrepparttar 100114 side rail ofrepparttar 100115 fixed panel and pulling as hard as you can. If you're lucky,repparttar 100116 panel will pop free. Then you can liftrepparttar 100117 panel up as far as it will go intorepparttar 100118 top channel and swingrepparttar 100119 bottom away fromrepparttar 100120 track, and removerepparttar 100121 panel. Now, I said "if you're lucky", because in most casesrepparttar 100122 panel will be stuck inrepparttar 100123 side jamb,repparttar 100124 bottom track, or both. Usually, you're going to have to use a pry bar to loosenrepparttar 100125 fixed panel before it will slide out ofrepparttar 100126 side jamb. Oncerepparttar 100127 fixed panel is out, removal ofrepparttar 100128 sliding panel is usually easier. Just lift up and swingrepparttar 100129 bottom away fromrepparttar 100130 track, then removerepparttar 100131 panel. Sometimesrepparttar 100132 bottom rollers will preventrepparttar 100133 bottom from swinging out ofrepparttar 100134 track. If that'srepparttar 100135 case, you will need to findrepparttar 100136 roller adjustment hole inrepparttar 100137 bottom corners ofrepparttar 100138 sliding panel. Put a screwdriver into this hole and turnrepparttar 100139 screw counterclockwise to bringrepparttar 100140 roller as far up intorepparttar 100141 bottom ofrepparttar 100142 sliding panel as possible. This should allowrepparttar 100143 slider to come out.

Now, you want to remove allrepparttar 100144 screws fromrepparttar 100145 side jambs, top header, and bottom track. Then, take a pry bar and get it underrepparttar 100146 bottom track about inrepparttar 100147 center. Pry up untilrepparttar 100148 track is separated fromrepparttar 100149 floor. The next step will depend on whether your old frame is nailed torepparttar 100150 house frame, or simply screwed in. If it's screwed in, thenrepparttar 100151 frame should now be loose inrepparttar 100152 opening, since you removed all ofrepparttar 100153 screws. You just need to remove whatever inside trim there might be aroundrepparttar 100154 door frame. This type of frame should come out. If your door is nailed torepparttar 100155 house frame, you will have to do a bit more work. Use a hacksaw to cutrepparttar 100156 track in half, approximately inrepparttar 100157 center. Start with either half and raiserepparttar 100158 cut piece up towardsrepparttar 100159 side jamb untilrepparttar 100160 the track piece separates fromrepparttar 100161 side jamb. Dorepparttar 100162 same thing torepparttar 100163 other half.
