http://www.younits.com Video Guide for how ductless mini-split systems work and its' advantages over conventional systems. The ductless mini-split system is becoming more attractive today. Similar to a conventional split system that has components on the interior and exterior, the ductless mini-split system would have a condensing unit or heat pump on the outside connected by a line duct to an air handler on the inside. The advantages of going with a ductless system over a conventional system are - cost effective; great for renovation work (no duct work required and installed in places where it's most needed); can be used in addition to existing split systems; very efficient (up to 26 SEER rating systems available on http://www.younits.com; quiet and sleek operation; attractive and low-profile; remote control operated. Several different styles are available depending on the best application for you. Wall-mounted units are very popular, but there are also ceiling-mounted units, ceiling cassettes (used with drop ceilings), concealed units (installed above the ceiling itself and has a small duct that gets tied into outlets) and floor-mounted units. Ductless mini-split systems can also be used in single zone or multi-zone applications. For multi-zone applications, it should be noted that you will need to use it with a heat pump. They are remote control operated, but you can also install a wall-mounted thermostat. Units can be used in a multi-zone application as a mix and match. For example, you can have a wall-mounted unit in 1 room and a ceiling-mounted unit in another. Go to http://www.younits.com to find products and applications for all your ductless mini-split system needs.

http://www.younits.com Video Guide for what makes a forced air split central system for heating and air conditioning work. A split central system consists of indoor equipment that includes a gas fired furnace or air handler, and outdoor equipment consisting of a condensing unit or heat pump. They are connected by a pipe called a line set. The gas fired furnace produces a flame that heats up a wire grid (heat exchanger). The blower blows this air through duct work in the house that comes out outlets to be drawn across the house through a larger duct known as the air return. The air return circulates air across the room, keeping it comfortable, and then returns back to the gas fired furnace where the process repeats. There are 3 styles of burners: 1 Stage, which just turns on and off; 2 Stage, which has a high and low setting; and the most efficient 3 Stage, in which the modulating increases or decreases based on demand. The blower motor is available as multi-speed (low, medium and high setting) and variable speed, which is more efficient. The available configurations for the gas furnace or air handler are Up flow (mounted in basement), Down flow (1st floor application) and Horizontal (for attics or crawl spaces). These systems are available in cost effective packages or can be purchased as individual components for customization. During cooling season, the outside unit has refrigerant pipes which transfer refrigerant back to the house and into the evaporator coil. Then, cold air will be transferred while removing humidity in the air. Cold air will be blown by the blower motor through outlets across the room and back to the unit to repeat the process. Heat pump systems produce heat during the winter. It takes cold outside air and compresses and condenses it to generate heat and that heat is transferred into the furnace to go through the house, repeating the process as before. Also available is a hybrid (dual fuel) system, which incorporates a heat pump and traditional gas furnace. During moderate times, the heat pump runs on electricity for heating and cooling and is more cost effective. The furnace will kick in automatically when there is greater demand.

Individual fan coil units. Central chiller, chilled water loop or D: A DX rooftop unit." So let's look at the question for a second and analyze it a little bit. So it's a three-story building, so that's interesting. It's multi-wing. That's also interesting. The university office building, so university office building implies long-term ownership. So this is not a developer going in, putting in a building, and condo-ing it or leasing it up immediately and then jumping away. This is somebody who's going to be holding a building, presumably. We don't actually know. But just from the little bit of information we have, it's a reasonable guess to say this is somebody who's going to be holding a building for a long time. That multi-wing aspect of things, if you imagine a building that in plan looks...how about something goofy like that...all right, so it's like a Y-shape or something. So if we start imagining three-stories, multi-wing, long-term ownership the answer starts coming out to us pretty readily. So let's run through them for a moment. Let's say we're talking about a central air-handling unit. So that means we'd have on one floor, maybe a basement or something a big air-handling unit. And that would be blowing air straight up through the building in great big trunk lines, and those trunk lines would have to go in all these different directions. That's going to be an awful lot of ductwork. That's going to be great big trunk lines. It's going to take up a huge amount of floor space, and it's not going to be wildly efficient because you're going to be pushing that air all over the building. So the air-handling unit would have to be pretty massive in order do this. If this was a centralized building, like a square or a simple rectangle, then it probably makes a little more sense...and it could easily be. So a central air-handling unit seems to me like it's a maybe, but probably not an actual answer. Let's look at B: Individual fan coil units. So the fact that it's individual offices, you could imagine a building filled with offices, and they have lots of small, fan coil units in each of the different ones. Similarly if it was a building filled with classrooms, you would have lots of these fan coil units in each classroom, spreading through the whole building. That seems unlikely, but possible. So I'm going to call that one another maybe. Then we have it down to C: and D: The central chiller, chilled water loop and a DX rooftop unit, and the answer in my mind, obviously any of these could be the potential answers. It's hard to know for sure, but from the limited information that we have, a DX rooftop unit just seems really unlikely. Rooftop units have a relatively short lifespan. Because they're up on the roof and they have to deal with all the rain, and snow, and sleet, and UV rays, and all that stuff. So they're great in situations where a 15-year lifespan is perfect. That you're going to put it up on top of a strip mall or something like that, that's going to be just fine. You're going to put it on top of many other types of places that have that fast-paced likelihood of change-out, and it has a low first dollar cost which is great, but not necessarily a really efficient lifecycle cost. With the university lifecycle, cost is really going to be a big part of their decision, so a DX unit just doesn't seem plausible. So we're left with C: and C: is the answer. I'm going to suggest it is. So C: is the answer. Let's talk about what a central chiller, chilled water loop actually is. So imagine we have a three-story building, and I'm going to simplify it. I'm not going to worry about the wings on this particular version. So we have a three-story building. I've given it a basement, although obviously it doesn't need to have a basement, and somewhere down in that basement, I'm going to put the chiller in. So the chiller is going to be a device that's one big box that has two barrels on the sides. The chiller is going to be a device where I can move heat around. When we talk about cooling, that cooling is done, not by creating cool, really. What you're really doing is removing heat, and the chiller is the device that's going to do that. So the chiller's going to take heat out of one side, one of the barrels and it's going to create a coolness in that by removing the heat.

Proper alignment will help you to achieve professional looking results by balancing the borders around the edges of your room. In this example we’ll use 2-foot square tiles. First, measure the room in one direction. We’ll take the length of this room. Round that measurement down to the nearest even-numbered whole foot. Subtract the whole foot number form the room dimension. Add 24 inches to the result. Take the result and divide by 2. This number will be the size of the border tile for the direction you measured. You will want to run a chalk or a string line along the wall to mark this measurement for the length of the room. Let’s run through it again to review. Now we’ll measure the width of the room. We’ll round that measurement down to the nearest even-numbered whole foot, subtract the whole foot number from the room dimension, add 24 inches to the result, take the result and divide by 2. This number will be the size of the border tile for this room dimension. Mark this measurement with chalk lines or string lines for the width of the room. Check the intersections of the border measurement chalk or string lines at the corners of the room to verify that they create a square 90-degree corner. Here are some important notes on making your border tile calculations. First, the border tile size won’t get larger or smaller in relationship to the room dimension. So it’s possible you may end up calculating a larger border tile for the shorter room dimension. As long as you follow the formula your measurement will be correct. Second, you may be tempted to skip the formula and simply fill the leftover gap you have between the room dimension and the maximum number of whole tiles that will fit. We recommend that you stick with the formula. We’ve worked hard to help you create the most professional quality installation possible and following the instructions carefully will ease your installation. Last, if you’re using 2’ x 4’ tiles, and would like to plan out your border tiles proportionately, this version of the calculation is in the tips section at the end of the video.

So this is a little bit of a trick one that's meant for you, to make sure you're reading it. In a typical tenant office construction...so it's an office-building, bunch of tenants in the building. It uses the tenants, so there's lots of different people. The supply system is usually ducted plenum, always cooling, and a VAV box. The thought here is that ducted seems way too simple of an answer. That plenum, that sounds like a good word. VAV box, that also sounds like something interesting. The answer is actually A: Ducted. In a typical system, in a typical office, I'm going to have a dropped ceiling. I'm going to have people working in the office, sitting at desks, doing what they're going to do and I have this big space above the ceiling where I'm going to be bringing a ducted supply. It's going to go all over the building and it's especially going to go over near the perimeter windows. Let's say we've got windows over here, and it's going to blow air into that space. That air is going to blow through, and keep everybody nice and conditioned. Let me make clear my ceiling here, and then we're going to put essentially holes into that ceiling. Those holes will probably look very similar to the typical supply vent register. But there's going to be a hole into that ceiling and that whole space up here, the entire interstitial space above the ceiling and below the structural deck is going to be the plenum area. That plenum area is going to be attached to a duct that's going to be the return duct, and the supply ducts are going to be attached to those original ducts that we talked about. That return duct then essentially incorporates that entire interstitial space. So if I have the air-handling unit pushing air out through the supply system, then it will automatically create a vacuum behind it, and it's going to pull air from behind it. Well, where's it going to pull from? It's going to pull from the trunk lines of the return system. Where are they going to pull from? They're going to pull from the branch lines of the return system. Where are the branch lines going to pull from? Well, they're going to pull from these plenum spaces. So all of this space is essentially going to be a way for the air to get a vacuum, and pull that air up through. And it's going to want, all by itself, to get up into that space because of that vacuum pull. When all of that happens correctly that means that this thing is pumping air out into the space, into the locations that you need and want it, typically over by the edges, by the perimeter. Then allowing the return air to find itself way up into the plenum, and then from there into the return system, and then from there back into the air-handling unit, where it gets reconditioned and blown out, as supply air and as other things. You have some outside air that is added in, so maybe humidification or dehumidification happens along the way. But that's the gist of that system of those office tenant kinds of scenarios. This is probably 80% of it is, just like this, so very, very common. If this thing had said the return system here, I would have said the answer was B: Plenum, but because it's talking about the supply system it would be ducted. It's quite possible that you could actually have it the other way. You can have a plenum supply system. It doesn't happen as often in this kind of scenario for various reasons, but it could. So there's lot of different ways you could it. But at least 80% of the time it's going to be something like this, so that would be much more expected on the exam. Marc: One question here is, "Is the VAV box not the correct answer based on the fact that it's only part of a ducted system?" Mike: Yeah, the VAV box, the thing that you don't know is the supply like I said, the vast majority of the time it's going to be ducted, but you don't necessarily know that it's going to be a VAV box. It could be a variable air volume box, a VAV box. It could be a CAV box, a constant air volume box. It could be that it's some mix of those two. There's a whole range. The VAV's are just a pretty common one, but there's a number of other common ones, as well. And so, yeah, that's not a bad answer. But I don't think it's as good an answer as just being ducted because that's really in play with the idea of the plenum. But yeah, I hear the question and I think that's a good question. It's just that there's a lot of other choices, as well.

Are you planning an addition to your home, currently using radiant heating or having a hard time getting ductwork to the room you want heated and cooled? A ductless mini-split system could be the perfect system for you. A ductless mini-split unit is similar to a window air conditioner or heater, but the noisy part of the system is located outside. These heating and cooling systems are cost-effective and easy to maintain. These units are great for retrofitting and remodeling projects in new and older homes. Ductless mini-splits are extremely energy efficient and are much less costly to install than traditional systems. A ductless mini-split may qualify for a rebate and make the cost of installation even smaller. If you would like more information about energy efficiency, visit our website at powerhousetv.com, or find out when you can watch a full episode on your local Iowa or Wisconsin TV station at http://www.powerhousetv.com/GetShowInfo/StationsShowTimes/.

Manually managing firestop installations is a thing of the past. Automating your processes with smarter software has the power to change the way you work. Using customized clash detection, the new Hilti Firestop Plug-in identifies penetrations going through fire-rated barriers, so you can easily see what needs to be firestopped. Hilti Firestop Plug-in for Autodesk will recommend products and systems for penetrations based on attributes in the model - and you still have the ability to approve or adjust as needed. Now your modeling software can generate firestop submittals and bills of material - it's never been easier to calculate and order what's needed including a customized waste factor. Automatically insert firestop objects into your model which can be used for point creation - then transfer those points to measuring tools for quick and easy site layout. Hilti Firestop Plug-in for Autodesk provides the most current listed systems along with relevant submittal documents, so the firestop inspection process is easier than ever before. Product specs are available for the entire project, which means less rework and more accurate planning for maximum efficiency. The new Hilti Firestop Plug-in automates tasks that used to take hours, like manually identifying penetrations, selecting systems, and inserting firestop objects.
