This article is going to be about replacing an old sliding glass door with a modern Vinyl frame sliding glass door. If you currently have french doors and you want to replace them with sliding doors, or vise versa, future articles will cover that topic.

The first thing we have to do is measure forrepparttar replacement door. You want to measure acrossrepparttar 100086 bottom, center, and top ofrepparttar 100087 existing door frame to findrepparttar 100088 narrowest dimension. Start outside and measure atrepparttar 100089 point whererepparttar 100090 old door frame stops andrepparttar 100091 exterior material starts. That material can be stucco, siding, or brick. Measure across inrepparttar 100092 3 places: bottom, center, and top. Recordrepparttar 100093 smallest dimension. Then go inside and dorepparttar 100094 same thing. You want to measure whererepparttar 100095 frame ends andrepparttar 100096 drywall, plaster, or sheetrock begins. Take all six measurements, findrepparttar 100097 narrowest one, and deduct 3/4". That isrepparttar 100098 width ofrepparttar 100099 new door. Now, when you measurerepparttar 100100 height, you can do it just onrepparttar 100101 outside. Measurerepparttar 100102 left, center, and right side fromrepparttar 100103 ground whererepparttar 100104 bottom track sits, up torepparttar 100105 top whererepparttar 100106 old frame ends andrepparttar 100107 exterior material begins. Takerepparttar 100108 narrowest dimension and deduct 1/2". That is your height ofrepparttar 100109 new door. Then, determine which siderepparttar 100110 sliding panel should be on. The fixed panel is designated byrepparttar 100111 letter "O", andrepparttar 100112 slider is an "X". In most areas ofrepparttar 100113 country, you call it out by looking atrepparttar 100114 door from outside and reading left to right. So, if you were outside looking at your door, and you wantrepparttar 100115 sliding panel to close torepparttar 100116 right wall, you would ask for an "OX". However, because i have recently discovered that not all parts ofrepparttar 100117 country do it this way, my suggestion is to askrepparttar 100118 dealer how they readrepparttar 100119 opening before placing your order.

Next, you have to decide whether you want a retrofit frame or a replacement frame. Ifrepparttar 100120 old frame

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.
