A solar-powered air conditioning is an interesting invention. If you think about it, use the sun to power your air conditioning, and in turn helps you less to global warming. In essence, you use the sun to keep the situation calm. There are a few companies worldwide that are working to develop solar powered portable air conditioner units that place a lower demand for energy and are environmentally friendly.

American company, which was released Greencore Air this air conditioner powered by a 170 watt solar panel. It can cool a large room, and runs off a battery bank when the sun does not shine. The portable version of this environmentally friendly air conditioner comes on wheels so you can easily move it around the house. MacDonald’s in the U.S. and the U.S. Navy has invested in some of these air conditioners for a test drive.

Rotartica, a Spanish company, has developed a similar small-scale solar air conditioning unit. Rotartica have used the latest technology to combine vacuum tube solar collectors with a water-heated absorption chiller. The unit takes in the sun-heated water and let cold air. Unfortunately, it has no capacity to run at night but it will cool a room on hot days without having to use electricity, which is under pressure on those hot days.

Another American invention may Solcool Millennium run on solar panels, a wall outlet or even batteries. Even if they use coal-fired electricity, they are still energy efficient. Solcool latest devices also have mounts for water. Explains the reason for the evolution of these solar-powered units, “said Roger Pruitt, CEO of Solcool,” Air conditioning takes the biggest load on the grid. We try to use small PV (photovoltaic) cells and equip them with 18,000 BTUs (a unit of energy) of air conditioning “. Unit operates at 500watts which is far less power than other devices use.

The development of solar powered LG portable air conditioner units have been going on for a while. The Chinese company, wide, for example, began to install their devices in 2006. Air conditioners are important in most homes, but they contribute to pollution and high energy bills. If solar energy is effectively developed, it can be used for all heating and cooling systems in homes and businesses, and costs would reduce the long term.
