A PARADOX REVISITED
AIR CONDITIONERS AND SOLAR POWER
It’s just stinky hot and of all things, your solar air conditioner
loves it. Silly thought, an appliance designed to cool the heat of the sun
that works from the heat generated by the sun. Inventors are coming up with
new and more innovative ways to leash the energy of the sun and the paradox
of the solar power air conditioner is just fun to think about.
When in Rome Use A Solar Power Air Conditioner (Romans defied convention, too)
It evokes wonder to know that the Romans, in their acme of civilization,
used a natural form of air conditioning or ventilation. They used to dig
a trench just leading from their house to about 100 –200 yards in
a straight line away from the house. A pipe and chimney were fitted in it
such that the heated air in the chimney would rise, drawing air through
the cool pipe. The pipe, which was underground, cooled the air to the temperature
of the earth. This cool air was let to circulate through the house to keep
its temperature lower than outside.
It's Possible Today
With the development of Direct Absorption (DFA) in Japan in the 1960s, solar
cooling technology took off. In 2004, BROAD Air Conditioning Co. Ltd. provided
an American customer with the first solar power air conditioner. It has
worked exceptionally well. Today, it is possible to cool down the heat generated
by the sun by means of battery-powered air conditioners such that the battery
is charged by solar energy. The solar modules charge the battery during
the day, when the sun is high, while the solar power air conditioner can
be used anytime.
Direct Cool Air Conditioning Inc. has created its own energy efficient DC
Airco units. These solar air conditioners consume less than half power requirement
of an AC input system. They are good cooling devices for small houses and
cottages, industrial buildings; telecommunication cabinets etc. A couple
of these air conditioners can be used to cool a larger structure. Since
the units operate on low voltage (24/48 DC) batteries, they are ideal for
replacing expensive external generators. These cooling units are available
as wall-mounted devices.
Advantages of DC Airco Solar Air Conditioners
DC Airco Solar Conditioners consume less power and provide greater cooling. They can be used anywhere in the world because they are not frequency dependent. They do not require Genset for power supply, and do not need an inverter.
