12000 BTU – With Heater

Now, for those who want to really conserve energy, YMGI created a solar powered ductless heat pump. During periods of peak sun, one photovoltaic panel is sufficient to power the entire system, providing reliable air comfort without consuming electricity. Those features also make it a reliable option for hotels, sunrooms, offices, restaurants, mobile homes and more. Of course, YMGI’s solar powered ductless heat pump …

Solar Air Conditioning | Solar Cooling & AC | Solar Absorbtion Chillers & Air Conditioners

Solar powered air conditioning systems is one of the most efficient and cost effective solutions for commercial air conditioning. Solar air conditioning employs time tested absorption chillers made by Yazaki.

Absorption chillers are powered by heat (hot water). Many thousands have been installed using gas boilers or by harnessing waste heat from generators or other sources.

Evacuated tube collectors are one of the most effiecient and effective producers of solar hot water. Therefore, absorption chillers run very effectively with a proper solar thermal configuartion.

How Solar Air Conditioning Works

The solar air conditioner / solar heater is powered by solar energy collected in the evacuated tube solar thermal panels (right). The thermal energy collected is then delivered to the solar powered chiller using a Corn Glycol (antifreeze) solution and a simple but carefully designed system of pipes, pumps, and controls.

In the winter, even at below freezing temperatures outside, our evacuated tube solar thermal collectors still produce an abundance of heat. The system can be designed so that this heat is then transferred into your building, either reducing or nearly eliminating the operation of your existing heating system. This means free solar air conditioning in the summer, and free heating in the winter.

See Diagram of Solar Air Conditioning / Solar Heating System for more information.

About Solar Air Conditioners

Absorption chiller air conditioners are not a newly developed technology. In fact, they have been commercially used in the U.S. since the early 20th century and are still very widely used to this day. Absorption chiller AC units are also very popular in Asian countries like Japan, where the high cost of electricity make them very desirable. Chillers constitute up to 40% of all installed commercial air conditioning tonnage. They are simple and dependable, using no harmful CFC (Freon, etc.) and some units actually operate without any moving parts.

When engineered to run on solar energy the absorption chiller AC units provide the lowest cost to operate and the best return on investment of any air conditioning system in the world.

Solar absorption chillers are very low in operating and maintenance costs, and consume little or no electrical energy. Essentially the only parts that use electricity are low amp fan motors and small pumps that move the thermal transfer fluid (Corn Glycol, a food-grade antifreeze) from the collectors to the chiller and then back up to the collectors. Inside the unit is another small pump that circulates the refrigerant. There is no “compressor” to consume power. All of these small electrical loads can run from solar PV panels if desired, meaning zero operational costs for the solar air conditioning system.

This has become an increasingly attractive system for commercial and industrial applications. Air conditioning is one of the most expensive operating costs that a business faces today. Absorption chillers are efficient, reliable, low maintenance – and even better, able to be powered using only the sun. Solar cooling has the direct ability to drastically lower your energy and operating costs.

Finally a Solar-Powered Air Conditioner: 6 Tons of A/C Using 4 Solar Panels : TreeHugger

In 2007 we covered a Coolerado A/C system with the headline “getting close to solar powered air conditioning”. Back then, the unit produced 5 tons of cooling using 1,200 watts, getting within the range of what some people and small businesses could afford in solar panels. Now, the new Coolerado design can produce 6 tons of cooling using 600 watts, quite an impressive improvement!

Read on for more details an a video detailing how it works.Boosting Solar Power Production TooOne interesting trick that Coolerado has – and that you can see in the video below – is the use of exhaust air from the A/C unit to cool down the solar panels. The reason for that is that solar panels produce less electricity when they get too hot, something that happens on the sunniest days when A/C is most needed. But cooling down the panels with exhaust air (that would need to thrown out anyway because it contains too much humidity) allows them to keep producing more, reducing costs because fewer panels are needed.

The demonstration video is quite well done, check it out:

One of the downsides of using an evaporative cooling system is that it uses water. About 4 gallons per hour for the 6 tons system, or 96 gallons a day. In some very dry areas, this can be a lot, though it might still be better than using a regular A/C that uses tons of electricity. A good compromise would be the use of gray water (stored in a holding tank underground so it stays cool?).

Keetwonen: student housing in Amsterdam

Keetwonen: student housing in Amsterdam.

1050 x 40ft containers = 320,000 sq ft

Keetwonen is the name of the biggest container city in the world (we know of no other village of shipping containers of this size: do you?). Living in a converted shipping container was a new concept in the Netherlands when launched by Tempohousing, but the city of Amsterdam took the courageous step to contract Tempohousing to go and realize it. It turned out to be a big success among students in Amsterdam and it is now the second most popular student dormitory offered by the student housing corporation “De Key” (www.dekey.nl) in Amsterdam (and they have many). The initial fears of some people that the container homeswould be too small, too noisy, too cold or too hot, all turned out to be unfounded: : they turned out to be spacious, quiet and well insulated and certainly offer value for money, compared to other student homes in the city.

They also come complete with amenities often missing in other student dormitories: your own bathroom and kitchen, balcony, separate sleeping and study room, large windows that provide daylight and a view and even an automatic ventilation system with variable speeds. The heating is from a central natural gas boiler system. The hot water is supplied by one 50 liter tank per home and a high speed internet connection is included, as well as a central audio phone system for visitors at the main door downstairs. The whole project was designed with an eye on how students like to live: a place for yourself, not having to share the shower and the toilet with strangers, but at the housing container Bachelorprefab housing unit professor interiorprefab housing unit professor interiorprefab housing unit professor interiorsame time lotprefab housing unit professor interiorprofessortypess of possibilities to participate in the social life of the dormitory, including the many parties that come with being a student. The blocks have a closed off internal area for safe bicycle parking.
