Your air conditioner needs the most power when the sun is shining, a coincidence you can take advantage of with our GEIHY12H/C solar air conditioner. It can keep an indoor area cool during the day for pennies. Literally, pennies, operatingabove SEER 35 with only two solar panels connected. Use this system to cool a small area or to augment a larger system. The unit uses as much solar energy as is available and any shortfall is obtained from utility power with no need for batteries. Even when the sun is not shining at all, this ultra high-efficiency SEER 20 heat pump will keep you comfortable and save you money using far less electricity than a normal AC or heat pump unit of the same capacity. *SEER 35 w/ 2 panels. SEER >19 at night.
Like all DC-Inverter air conditioners, the GEIHY12H/C compressor runs on DC power converted from AC power. But this special solar air conditioner can also accept DC power directly from solar panels, without needing an inverter, controller, or batteries. The solar DC power directly replaces an equivalent amount of AC power from the power company and can cut daytime energy costs for air conditioning or heating by 80-90%.
During the day, the GEIHY12H/C can get most of it’s power from solar resulting in an efficiency above SEER 35 when using two 230W solar panels. Max is 20amps at 39vdc solar. The unit can be connected with up to three 250W panels up to 750 total Watts. The system is designed for hybrid operation with solar providing most of the energy needed during daylight hours. This air conditioner must be connected to a 220VAC power source and is not designed for off-grid operation.
Thermal Air Conditioning
The sun’s energy is free so why not use it?
Air conditioning is expensive to run…right? Not anymore. The Thermal Air Conditioning system uses the sun as a heat source rather than a power source to assist the energy needed to drive the cooling process of a typical air conditioning system. This significantly reduces the electrical consumption required to run the compressor so you’ll make big savings on electricity costs.
Innovation that improves operation and extends running life
A thermal air conditioning unit uses solar thermal energy to improve the operation of the condenser. This reduces the amount of electrical energy required for operation and as the compressor is only required intermittently this means that the operational life of your unit is extended.
Enjoy the peace and quiet of silent running
The condenser in a unit is 10dBA quieter than a conventional air conditioning unit. That’s because a fan head uses an advanced off-centre blade fan and foam air duct. This innovation means better performance and much less noise than conventional units.
Economical to run even on cold days
The reverse cycle function, with its microprocessor control, enables economical heating even on cold days. Just because the sun isn’t out, it doesn’t mean that your unit stops working. For every 4-5 hours of sun / UV exposure, you’ll achieve 15 hours of continuous use.
Achieve the level of comfort you want in less time.
A conventional air conditioning unit has to run for 75% of its set time to achieve the desired internal conditions. A unit only needs to run for 20% of the time to achieve exactly the same result. When you add this outstanding feature to the design changes we’ve already mentioned, you’ll achieve long term use with much less power consumption.
Simple to operate
How does the system work?
In a Thermal Air Conditioning System the sun is used as a heat source to reduce the energy needed to drive the cooling process which in turn reduces the electrical energy required to run the compressor. The Thermal Air Conditioning System is similar to a standard air conditioning in that the refrigeration takes place by evaporating liquid with a very low boiling point. In both cases, when a liquid evaporates or boils, it absorbs energy in the form of heat and can continue to do so either until the liquid is boiled or until everything has become so cold that the sub-zero boiling point has been reached.
The difference between Solar A.C. and a conventional A.C.
The difference between a unit and a conventional unit is how the gas is changed back into a liquid so it can be used again. A standard air conditioning system uses a compressor to increase the pressure on the gas, so that when it enters the condenser coil the combination of pressure and cooling from ambient air condenses it into a liquid in the coil. The change of state of the refrigerant begins to take place approximately two thirds of the way down the condenser.
Why is the system better?
The Thermal Air Conditioning System improves on this basic method by using the heat from the sun to add thermal energy to the refrigerant vapour which increases the difference in temperature between the refrigerant and the ambient air hastening condensation. By using this method it reduces the superheat of compression required to achieve the cooling process in the conventional cooling system as well as utilizing more of the cooling face of the condenser coil.
The conventional cooling system is only able to change a portion of the gas into a liquid state so that as it enters the metering device, or capillary, it is a saturated vapour.
The Thermal Air Conditioning process allows more of the refrigerant to change state back into a liquid faster as well as allowing the transformation of more liquid into the metering device.
In a air conditioning system the low pressure, low temperature refrigerant is compressed before gaining solar thermal energy in the heat exchanger of the solar absorption panel so that we now have both higher pressure and higher temperature vapour.
Then the vapour is condensed into high pressure liquid at ambient temperature by passing through the condenser. The high pressure liquid is converted into low pressure, low temperature vapour at room temperature when it passes through the capillary before entering the fan head.
This is achieved by throttling and decompression of the liquid into vapour at low pressure and low temperature in the capillary. This phase change absorbs energy out of the room in the evaporator inside the fan head. Air is blown through the condenser to distribute the cooling throughout the room. Moisture forms on the surface of the evaporator coil where it is piped away to the nearest storm water drain.
In the heating cycle the condenser and evaporator are reversed in sequence so that heat energy is released in the fan head instead of outside.

Note: To convert to a SEER (Seasonal Energy Efficiency Rating) multiply the EER by 4.2.
For a variable speed compressor, this test has a problem in that the initial operation of the compressor is to operate at 120% of rated output until stability is reached. This, of course, gives a very poor rating that will not comply with the Minimum Energy Performance Standards (MEPS) of countries such as Australia and the USA. As most manufacturers are now relying on variable speed compressors for sales, a concession was made to allow such systems to be tested at half power to enable compliance.
This produces a skewed result and is not a reliable test of the efficiency. If the speed is fixed at 100hz or maximum power, a variable speed compressor system will exhibit an EER of 3.66. This can be verified from the data supplied by the manufacturers by dividing the full power cooling out by the full power electricity in.
