In automobile we know that 7/5 part of energy is untouched in the form of wasted heat energy through the engine cylinder, released to the atmosphere via cooling oils and considerable amount through the exhaust gases. The heat released through the exhaust, the temperature of the gases lies between 655 to 955 degree Celsius. That unused heat energy can be used to run or operate the components of the vehicles such as alternator, water pump, AC compressor, and some of the other components. Employing this wasted heat energy improves the efficiency of the vehicle, and reduces the fuel consumption by engine.
Dirt and moisture should not be present in duct systems, and must be controlled to prevent mold growth. However, it is not always possible to assure that ducts remain dirt and moisture free. In many existing buildings, sheet metal ducts, as well as those constructed of or lined with insulation products, are often contaminated with mold because dirt and moisture found their way into the system.
Indoor unit: It is the indoor unit that produces the cooling effect inside the room or the office. This is a beautiful looking tall unit usually white in color, though these days a number of stylish models of the indoor unit are being launched. The indoor unit houses the evaporator coil or the cooling coil, a long blower and the filter. After passing from the expansion coil, the chilled Freon fluid enters the cooling coil. The blower sucks the hot, humid and filtered air from the room and it blows it over the cooling coil. As the air passes over cooling coil its temperature reduces drastically and also loses the excess moisture. The cool and dry air enters the room and maintains comfortable conditions of around 75-77 degree Celsius as per the requirements.

An impeller is a rotating component, usually made of iron, steel, brass, aluminum, plastic. In many cases it also called as rotor. Here, engine exhaust gas is used to operate the impeller, which is further connected to the compressor or alternator by pulley. If it is possible to run the compressor by impeller at certain rpm developed by impeller and if no then impeller is used to operate alternator, which further generate electricity which further drives the motor to run the AC compressor.
Air conditioners use chemicals that easily convert from a gas to a liquid and back again. This chemical is used to transfer heat from the air inside of a home to the outside air.
The window air conditioner is the cheapest of all air conditioning systems. If your room or office size is about less than 655 sq. ft. a window air conditioner of about ton can be good enough. If the size of room is more than this but less than 755 sq. ft. your HVAC designer will recommend a window air conditioner of about 6 ton. For rooms of bigger sizes but less than 855 sq. ft. the system of about ton is advisable. However, these sizes may change depending upon the number of people occupying the space, its alignment with respect to sun, and other sources of heat generation inside the room. It is better to consult your HVAC designer to find out the exact size of window air conditioner suitable for your space.
Since there is long distance between the indoor and the outdoor unit, there is always loss of some cooling effect hence for the same tonnage, split air conditioners produce somewhat less cooling effect than window air conditioners. However, with modern insulation material this gap has been reducing between the two. In any case, there are number of instances where there is just no alternative to the split air conditioners.
Most of us take the AC in our automobiles for granted. We don't give it much thought during our daily commute. The only time we think about it is when we it starts giving us problems. But just like all the other important part of a vehicle, its AC should also be maintained properly. Especially in the cities where we get a lot of sunshine, a car without a proper AC is nothing less than a solar heater. It can be quite a punishment to travel in such a car.
Extended surface area filter bank - To reduce the frequency of filter maintenance and the cost of fan energy, the bank is designed to allow more filter area, such as the deep V approach or bags.
