Air Conditioners

Legionnaires’ disease can spread when water in a building's air conditioning system becomes infected with Legionella bacteria. Checking for that bacteria takes up to two weeks, and requires water samples to be sent away. The Spartan Cube, however, can do the job on location in less than an hour.

Over the last few years a Stanford team has been developing a roof-mounted system that cools a building by reflecting heat into space, and the latest test has managed to use solar panel-like devices to cool water without needing any other energy source.

Solar-concentrating thermal technology is being used to power the air-conditioning system of an entire shopping center in Australia solely from the rays of the sun. It is expected that this technology will help drastically reduce commercial building energy use.

An MIT team has developed a new solar power system for developing regions that works like an air conditioner in reverse.

Diamond-Power skylight panels are designed to harness solar energy, while reducing the solar heat load on buildings.

Researchers in Hong Kong have developed and completed a series of on-road tests on a solar-powered AC system installed on top of a truck.

The AIR-igator system collects condensed water from air-conditioners, stores it and automatically waters gardens.

Raser Technologies has begun delivering 10 megawatts (MW) of clean, renewable electricity to Anaheim, California, from its first low-temperature, binary geothermal plant, the Hatch Geothermal Power Plant in Beaver County, Utah.
