In winter, heat pumps work exactly the same way. But this time they pick up heat from outside and move it into your home. Of course, it’s sometimes freezing outside when you want to use your heater. But the air doesn’t need to be warm— it just needs to be warmer than the re...

” Packaged systems contain the evaporator coil, blower fan, compressor and condensing coil all in one unit. They work well when there isn't enough space in an attic or closet for the indoor unit of a split-system air conditioner. They are also a good choice in areas where rooftop...
The evaporator coil functions as a heat absorber, pulling warmth from the air and thus cooling it. Once cooled, a fan propels this air through air ducts. Meanwhile, as the refrigerant inside the evaporator coil absorbs heat, it transforms from liquid to gaseous and then heads toward the com...
How do air-conditioned seats work? Do they still use a central car air conditioner or is the air conditioner located in the seat itself? How does the air get out of the seat so that it can cool the person sitting in it? Can you buy air-conditioned seats for cars that don't have ...
the inner spiral oscillates inside the outer spiral. The two work together to compress the air by decreasing its volume. Air is then sent to the center of the compressor to be cooled. The spiral scrolls in this design do not make contact, so this type of oil-free compressor does not req...
More than 100 years ago the Wright brothers made their historic first flight in Kitty Hawk, N.C. Even after all these years, their creation still boggles the mind: How can something so heavy take to the air?

the split-system approach begins to run into problems. Either running the pipe between the condenser and the air handler exceeds distance limitations (runs that are too long start to cause lubrication difficulties in the compressor), or the amount of duct work and the length of ducts becomes un...
Operation of Air Conditioning Pack When bleed air goes through the primary heat exchanger, ram air removes some of the heat. This partially cool bleed air goes to the compressor section of the air cycle machine. The compressor section increases the pressure and temperature of the partially cool ...
