Window AC units converted into super quiet inexpensive Houses Built Tiny Central AC 

Thank you for your comment

How is that build mobile?

FloridaFrank2010 look again in a couple of days and will show you the completed version

We converted a 42 seat passenger shuttle bus last year into a traveling tiny house. It had a fantastic air conditioning and heating system in it already we just fixed the system that was there that ran off the diesel engines. Those are super super efficient. But of course you have to leave your engine in idle which it is designed to do. But it was more for traveling than it was for staying long-term anywhere. Insulating it was a booger bear but it turned out pretty fantastic.

Thank you. One of the best comments ever made. I feel the same way

That was just our mockup design to see if it would actually work. You're absolutely right. We decided to not use any wood at all instead we used signboard which is a polyurethane core wrapped on both sides by aluminum and then vinyl. Then we fiberglass a posh eat everything together and insulated it from the outside check out our other video on are finished unit that is now close to 3 years old and doing fantastic. Thank you so much for your comment

They stopped selling it due to tarriffs.

Bro it's just a fan and compressornthey don't give a damn about your design, it just blows air. Only thing it will be more dehumidifing. And your estimations on lifespan are jist taken out your imagination

That's what I did on the kids' two story playhouse. Works wonderfully.

Steve Mac for the standard build you would be absolutely correct. But this house is built with Sips, triple radiant barriers with proper airspace between, fully breathable roof and full cedar rainscreens. It's so well insulated you literally cannot calculate the "R" factor.

You need more cooling BTUs because of appliances, cooking, and body heat from at least 2 people and a dog or cat, the compressor will be maxed out. I am building a Ac unit from a evaporator from the rear of a van, and a window unit compressor . It will be a split unit . And if you use a larger compressor and a accumulator inline with a dryer you can connect several evaporators place them in different areas with air filters. Condense refrigerant with larger condenser or copper tubing submerged in a body of water, like a lake or large rain water tower. This will eliminate the need for a condenser fan and reduce power consumption. Compressor can be a automotive type belt driven by motor, or 12 volt compressor from a Prius car, or from a window unit 110 vac can be made to run from a inverter and battery's with solar power. And it would use r134a refrigerant that is available to consumers without a license with the right combination of parts a whole house Ac unit can be built from auto parts and a used window unit compressor. Add ester oil to mineral oil not pag oil. This will work with the mineral oil and ester together, and will prevent black death of the compressor.

@@davidwilliam1406 nice tips!

Good observation Nathan. But in such a small freight placed the principles work in reverse. Check out the other videos that show the completed models as well as the thermal laser readings

Matt that's a really good question many people feel the same way. Here's my take on it in the four decades that I've been doing this. And I say for decades not to qualify myself as someone who knows something just know what I know there are so many different ways to do things. But it's how I have developed how I look at it. It's very hard to take cold air off the floor and bring it up once it has separated in a room and the hot air has risen. If that happens in a home that has conditioning then it's out of balance. To have a temperature within one degree everywhere in the room including in the top and bottom corners of rooms and closets even, one needs to reverse the flow that hot and cold air would have naturally if they were to separate. Reversing the flow of their natural separating keeps them blended in a cool even temperature state. So instead of trying to cool down hot air and then push it into more cool air You're simply maintaining one flow of air mass. In this tiny house we have taken the laser thermometer and checked everything on days that were 18⁰f outside and on days that were 110° f outside. We never found a spot that was more than one degree different on any of the walls ceilings floors corners behind cabinets or in the back of closets. It's extremely well balanced. And it's very very quiet you don't even know it's on

Test T, that was our original mock-up unit that we did as an experiment. Here's the link to our completed unit which is now 3 years old and in Texas runs pretty much every day.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eaM68n1aWko.html

Thank you for your comment. That's exactly right. But all the ones I saw cost in the thousands of dollars

If you find any that are reasonably priced please share it with us

Troy Hall Great questions! We have built a couple of units now and they are all working super efficiently! we have since upgraded everything to rigid Duct work. Check out the other video in this series to see what it looks like. because of the unique rain screens, radiant barrier, sip insulation/ construction, tall ceilings, 3 sided venting on the loft, thermal vented double roof and open floor plan, This unit doesn't need a lot to keep it cool or hot. The ac unit basically runs in Idol most of the day it doesn't pull much electricity at all. The cooling inside is extremely quiet and a gentle movement of air. In the morning we capture the early cool weather outside close the windows and just circulate the all house fan that is built into the unit and it keeps a gentle breeze blowing through out the house for hours while it continues to condense the moisture in the air keeping it very comfortable. in the winter time a small space heater on the floor produces enough warm air that circulates through the ductwork as the all house fan is on and creates a gentle warm flow leveling out temperature everywhere so that there are no hot spots and cold spots anywhere. You and I both know that just 10 degre temperature variations in corners, closet and non circulating spaces create mildew. there is none in this house. every corner is within two degrees of the ambient temperature of the room.

I wonder if this would work as well in a mobile home? We've got 3 units right now, and even though they are really nice window units they simply can't keep up. "Technically" each unit is more then big enough to cool the entire house but nope.

No sir it will not help. But there are things you can do to beef up the efficiency of your mobile home. Single wide, double-wide, skirting, age, type of siding, what you got maybe I can help I've done a lot of them?

it's a 74 14x56 metal siding with NO tyvek or boarding behind it. low peak roof clad same way with SOME cardboard ( yes cardboard!!!) between metal and studs. All insulated with R11, I'm seriously considering adding insulfoam ( 3/4 r 5.6) but haven't decided on wether to put outside under sideing or inside between studs and taped. If I go outside it'll be taped and felted. I'm in north central Oklahoma btw

What I've done in the past to make mobile homes like yours more efficient is this. Now I know this is going to sound like a lot but at the end I'll tell you how much usually cost and materials. First things first. Wrap your entire house in double bubble R foil. I like to start with the walls and then wrap the roof over the edge about a foot. Then build a metal roof on top by screwing down pressure treated two by fours horizontally one to the very edge of the eve, 1 about 8in on Center from the ridge, and then to rows between them over top of the r foil. Be sure to leave 1 to 2 inch gap between all the buttons of the two by fours and I like to make sure that the 2x4s are no more than 4 feet long. This allows for air and moisture flow freely above the are foil. Install Galvalume or colored R panel Roofing commercial grade don't go with the cheap metal up here you'll only save about $200 and you wish you had not done it the first year. Use a venting ridge cap and leave the eaves open but extend the eaves and Gables a foot past the edge of the existing roof it will take more than a 70 mile-an-hour wind to mess with that. That will also give you some overhang that well really help in the long run. Next round up a whole bunch of free cedar fence panels they're everywhere on the street talk to a couple of fence installers they'll have them waiting by the curb for you. Pull them apart and install them like we did our rain screens horizontally with a eighth of an inch Gap. And the two by fours on the back of those panels are easy to make trim pieces. Over the air foil on the walls you will first one to screw some pressure treated two by twos or two by fours rip down in half or just go ahead and put the whole two by four on vertically over top of the studs. This creates an air gap again over the our foil which is critical to insulating with radiant barriers. Pull any windows and doors off and frame width pressure-treated two-by-fours and this is where you might want to put in some new windows and doors if you have an extra amount in your budget. The foil that you put underneath of the house just needs to be stapled to the bottom of the underpinning and then make sure to put some cedar skirting around the house as well period for a house your size this should be about $3,500 in materials. Since most of the siding is free. You will notice and instant difference as soon as you wrap your house in the R foil. But don't leave it that way very long if you don't have it covered up in 90 days it's going to start falling apart. If you go this route and all the turn it into quite a beautiful home from the exterior we would love to see the video and be able to post it to show people what to do. I hope this helps :-)

Absolutely thank you for your comment. Check out R finished video

You can just as easily add AA heating unit as you can a full AC unit. My son has a professional Mini split cleaning company. Most of the homes he takes care of have 3 to 4 units and they pay him $1000 twice a year to clean the units. 50% of the year the units run at only 50% efficiency. Hes a professional even the Manufactures know that this is the case. Mini splits were designed for European stone buildings that have no area for duct work

Buddiga Nikhil Ram Goud not with out great difficulty

Portable units create a negative pressure inside the house because they pull air from inside and push it outside the house. The discharge heat tubes are not insulated so they discharge a ton of heat inside the house. Two downsides of portable units. Windows units are better because they release all the heat outside and only the cool inside.
