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.

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.
