What are the potential problems, if any, of venting a portable A/C unit into a closet or attic? August 13, 2010   Subscribe What are the potential problems, if any, of venting a portable A/C unit into a closet or attic? I've got a portable A/C unit, but no windows in the room I'm trying to vent. But there's an empty closet, and access to the attic. Could I just vent it into there? I've let it run for a while, and it seems no moisture is coming out of the vent -- just hot air. Forgive me if this is a stupid question. This is the the model I have. 1 year parts and labor Reconditioned (1 from $ 83.93) Select from available items Kenmore 6,000-BTU Room Air Conditioner Window Unit - Simple and Quiet Operation It’s easy to keep your cool when the temperature rises with the 6000 BTU Kenmore room air conditioner window unit 86052 . The unit’s relatively light weight of just over 40 pounds allows for single-person window installation. Easy-to-use push buttons and remote control make beating the heat a quick and simple operation.

Most importantly, with the window air conditioner quietly humming away, there’s enough power, 6,000 BTUs, to cool small rooms and studio apartments. This window air conditioner fits a window from 23 in. to 36 in. wide and at least 14 in. high.1 ton ac blue star 24-hour ON/OFF timer offers simple operation Sleep mode lets you save energy Auto Cool features one touch-controls Filter check reminder makes maintenance easy 8-way air direction control provides efficient cooling Electronic controls with full-function remote are easy to use The 410A refrigerant used for this unit is earth-friendly Kenmore air conditioner 86052 has a 9.7 EER ratingsizing ac units for homes Energy Information at High Speed:can you turn a window ac unit on its side

Owner's Manual - English (Warranty) Product Warranty - EnglishMany older homes were built with no provision for central air conditioning. Residential central air conditioners were uncommon prior to the 1960's, and even as late as 1980, were installed in only about one-fourth of U.S. homes. In homes with no central air conditioning, duct systems were rare, as there were other ways to deliver space heating. Until recently, the only options for air conditioning in homes with no ducts were either to use room units (window or wall air conditioners) or to install a duct system, which can be costly and impractical unless the home is being extensivelyremodeled. Now there is another option for homes with no existing ductwork - a ductless split-system central air conditioner orInstead of using a single central air handler with ducts running to each room, this system has multiple fan-coil units connected via refrigerant piping to a single outdoor unit. This system combines the zoning flexibility of room units (the ability to cool individual rooms independently) with the

whole-house cooling capability of a central system. The indoor fan-coil unit is smaller than a standard window air conditioner, and much quieter, as the compressor is located in the outdoor unit. The fan-coil unit can be mounted on a wall or suspended from a ceiling. Many come with a remote control, allowing the unit to be mounted high on the wall or on the ceiling. In addition to providing a new alternative for homes with no ductwork, this system can also be useful for additions where extending the existing duct system is impractical. Ductless central air conditioners are available with SEER ratings as high as 18 or 19 - comparable to the highest-efficiency ducted central air systems, but without the duct losses that can reduce overall performanceSome also incorporate variable speed high-efficiency fans. Heat pump versions that provide both air conditioning and space heating are also available. Currently, the initial cost is typically about twice that of traditional window units and about 30% higher than a standard

However, once the cost of adding new ductwork is factored into the equation, the ductless system may be a very Studies by the U.S. Department of Energy have found that as much as 25-30% of an average home's cooling is lost to unconditioned spaces like attics, due to inefficient duct systems. While it is possible to minimize these losses with insulation and proper duct design and sealing, it can be difficult and time-consuming. Although ductless systems are currently more expensive than traditional ducted systems, the additional cost can be at least partially offset by the savings from eliminating the ducts. When you factor in the energy and operating cost savings from eliminating duct losses, the total cost (initial cost plus annual energy cost) can compare favorably with ducted systems. Over time, as sales of these systems increase and costs come down, they may become a popular option for new homes.Air conditioning units are expensive devices both to buy and to run.

When they stop working, that’s also an expensive problem to solve. Even so, if you live in a location with unbearably hot summers, an AC unit is essential. Not everyone has that option, though, but they no longer need it because the Eco-Cooler has been invented. The Eco-Cooler is an air conditioner that requires no electricity to function and is created using waste products. It sounds too good to be true, but it exists and is in growing use across the country of its origin: Bangladesh, where 70% or residents live in tin huts without power. To make an Eco-Cooler you take a piece of board cut to the size of a window on your house. Then drill holes in the board big enough to push a plastic neck through. Gather some old plastic bottles and cut the bottoms off, then slide the neck of each bottle through the holes and secure them with the cap. Do this until the board is full. Hang the board on the window and watch the temperature inside drop. As the video below explains, the simple design works on the same principle as blowing air out of your mouth.

To test this, hold your hand up to your mouth then open your mouth wide and breathe out. The air is warm, right? Now do the same thing but with your mouth closed to typical a blowing position. The air leaving your body is cold, right? The bottles work in the same way: the larger end takes in the warm outside air and the change in pressure as it passes through the neck pumps cooler air into the house. The change in temperature using an Eco-Cooler is at least 5 degrees Celsius. That may not seem like much, but when you’re living in a tin hut with no power that can reach 45 degrees in summer, it makes all the difference. I think you could improve the cooling further by also creating one of these for over the door as it would be a much larger area than the window. With the abundance of plastic bottles and easy access to pieces of board, this would make for a great weekend project. Anyone fancy giving it a go? It would be a good project to do with your kids, especially if they plan on spending their summers in a hot tree house or garden play shed.
