It only lasted maybe 6-8months. The cooling feature didn't really make that much of a difference, but the heat was nice. In concept this sounds like a good idea. However it does not cool you. Either the fan is too weak or the design is poor. A must if you live here in South Texas I was quite disappointed with this item. It did not cool at all, I couldn't tell the difference between it being on or off other than the fan noise. I use this in my semi, I don't have AC, this really helps to keep you cool!

Works great but the cooler fan is kind of loud First one worked but two weeks then quit they replaced it. The second one still works but the hose that connects the fanbase is of low quality and they have already broke bought it "new" and I got a returned product with a note from a prior customer. The seat smelled of sweat due to this and it didn't install properly on my E93 BMW (2007)...Monogrammed Seat Covers For Cars See and discover other items: orthopedic cushion, rv cushions, truck seats, lumbar cushionTeddy Bear Puppies CareThe most well-known application for thermoelectrics in the automotive industry is the individualized heating/cooling of car seats. Vera Wang Wedding Dress Outlet UkDue to the unique advantage of thermoelectrics for this application, car seats in the front and rear cabin can be individually heated or cooled based on the occupant’s preference.

As the individual controls the temperature selection switch, airflow is directed through a thermoelectric heat pump, which adjusts the temperature. A fan circulates the temperature-controlled air through a ducting system integrated into the seat back and cushion, offering custom comfort for each occupant of the vehicle. The seat application, often considered a green-energy application, has the potential to reduce our national energy bill by enabling smaller compressors to be used for cooling the main cabin.

If you're looking for a low budget cooling an hearing seat cover with firm lumbar support, then you have found it. Got it as a gift for my bf who said it worked great as a seat warmer in the winter, except he couldn't really feel the air on hot days so much. Lumbar hurts you back once you sit down. Heater stopped working after one day. "Lumbar rest" aggravated back pain. I hunted for a combo cooling and heating, as I live in Maine, but am going to Florida for two months this winter. it is the coolest accesorio i ve ever have Wrong explanation about product I am looking fot cooling and this thing have heating too. I can't tell you how much this helps me during my daily commutes. I live in a very hot sticky tropical country and having leather seats doesn't help. Different car manufacturers implement air-conditioned seating in different ways. However, the standard model for air-conditioned seats, developed by scientists at the Department of Energy's National Renewable Energy Laboratory (NREL), works like this: The fabric of the car seat is a porous mesh, so air can flow through it.

Multiple fans inside the seat produce air circulation, which blows through a diffusion layer that spreads the cooling effect throughout the seat and outward through the mesh, cooling the surface. This air may or may not be refrigerated. Even unrefrigerated air is important in keeping you cool in your car seat. A standard car seat blocks your body's built-in cooling system. Ordinarily you eject heat through your pores in the form of water vapor, which carries the heat invisibly into the air. Having a seat pressing against your back and bottom prevents this water vapor from escaping, causing it to condense into sticky sweat. It's like wearing a jacket in hot weather. But the porous covering of an air-conditioned seat allows your body's natural cooling system to work even when sitting down and keeps you cool by circulating air across your skin. The moving air carries your body's heat away. But some air-conditioned car seats also use a cooling element. Like most air conditioners, these work on a compression, condensation, expansion cycle.

For more details, see How Air Conditioners Work. The short version is that air conditioning operates on a very simple principle: When a gas (in this case referred to as a refrigerant) is compressed, it becomes warmer and when it expands it becomes cooler. This principle can be used to remove the heat from a room, a car, or even a car seat and carry it elsewhere. Until recently, the gas most commonly used as a refrigerant in air conditioning systems was Freon, the commercial name for a chlorofluorocarbon (CFC) manufactured by DuPont. However, CFCs have been found to be destructive to the Earth's atmosphere, creating holes in the ozone layer and contributing to global warming, and are now considered too dangerous for general use. So Freon has been largely replaced in automobile air conditioners by the hydrofluorocarbon HFC-134a. 10 Car Features We Wish Came Standard How Laser-powered Headlights Work How Toyota Entune Works How can you use in-car Internet? In an air conditioner, this gas is run through a device called a compressor.

Then it passes through a condenser where it cools into a liquid, dissipating its heat in the process. (The dissipated heat is released outside the cabin of the car.) Finally, the cooled liquid is passed through an expansion valve, where it turns back into a gas. The expansion of the gas makes it even colder. This process takes place within a closed loop consisting of coiled tubes, so that it can be repeated over and over. Air is forced past the part of the loop containing the cold gas and becomes chilled. Constant input of energy is required to compress the gas, which is why air conditioning uses up so much of your fuel. Air-conditioned seats that use refrigerated air either contain a small cooling element based on this principle, or use air pumped from the main cooling element of the car's air conditioning system. Because the space being cooled is limited to a single seat, relatively little energy is required compared with normal car air conditioning. In the case of air-conditioned seats without a cooling unit, where the driver or passenger is cooled by the circulation of unrefrigerated air, the entire process requires less energy than is used to run a typical light bulb.
