Solar-powered AC Units

Going Green

Solar power is one of the newest most economic ways to get power. So why not solar-power your ac unit? The solar air conditioner/solar heater is powered by solar energy collected in the evacuated tube solar thermal panels (see below). The thermal energy is delivered to the solar powered chiller using a Glycol (antifreeze) solution and a simple but carefully designed system of pipes, pumps and controllers. Solar heating and cooling in the winter, even when it is below freezing outside, our special evacuated tube solar thermal collectors produce an abundance of heat that will be transferred into your building/house, either reducing or eliminating the operation of your existing heating system.
AAAAAAAAAAAA
GGGGGGGGGGG
Our solar heating and air conditioning units can be used anywhere that the sun shines; they are low in operating and maintenance costs. They 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 (Glycol, a food-grade antifreeze) from the collectors to the chiller and then back up to the collectors - all of these small electrical loads can run from solar PV panels if desired. Inside the unit is another small pump that circulates the refrigerant. There is no "compressor" to consume power
