Solar Air-Conditioner absorbs solar energy to heat the inside medium by using a vacuum solar collector. The heat is used as part of heat that compressor needs there by reducing the amount of electricity the compressor needs to change the refrigerant from gas to partial liquid. Then the refrigerant from the compressor goes through the copper coil inside the collector and undertakes a heat exchange. The refrigerant heated by the medium inside the solar collector will go through a cycle inside the system cooling and heating. We use a smaller compressor instead of standard compressor to run our system which saves electricity dramatically. A smaller compressor consumes much less electricity and by working together with solar collector saves electricity consumption.

In our system, a solar collector assists the compressor by raising the refrigerant fluid’s temperature before it enters the compressor, so less work is required from the compressor to reach the desired temperature of refrigerant leaving the compressor. By reducing the difference between the compressor’s inlet and outlet temperatures the compressor’s efficiency is improved.

The Solar Hybrid Air Conditioning System is similar to a standard a/c 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 all boiled or until everything has become so cold that the sub-zero boiling point has been reached. The difference between the two is how the gas is changed back into a liquid so that it can be used again. A standard air conditioning system uses a compressor to increase the pressure on the gas, forcing it into a liquid in the condenser coil. The change of state of the refrigerant takes place approximately 2/3rds of the way down the condenser. The Solar Hybrid Air Conditioning System uses a different method. It uses the heat from the sun to superheat the refrigerant which enables it to begin changing state in the top 2/3rds of the condenser coil.

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 it is a saturated vapor. The Solar Hybrid 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 hybrid solar ac system the low pressure, low temperature refrigerant is compressed before being superheated in the heat exchanger of the solar absorption panel so that we now have both high pressure and superheated vapor. Then the vapor 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 liquid at room temperature when it passes through the capillary in the fan head. This is achieved by throttling and decompression of the liquid into vapor at low pressure and low temperature. This phase change absorbs energy out of the room in the condenser inside the fan head. Air is blown through the condenser to distribute the cooling throughout the room. In the heating cycle, the condensers are reversed in sequence, so that heat energy is released in the fan head instead of outside.

1.Freon passes through an attached high pressure thermal solar vacuum system before entering a smaller compressor; heating the Freon to about 170 degrees F to 230 degrees F, sending the hot Freon Gas to a dual condenser for cooling and turning to a liquid.

2. Now Liquid Freon converted from the dual condensers outside, is sent to the inside blower / evaporator, with double and triple evaporators combining with warm air, providing cold air to the home or business.

3. Then Freon will again return to the high pressure thermal solar vacuum system for added heat processing before entering the compressor.

4. Again the process begins; Freon will be heated by the assisted thermal pressurized vacuum system before entering a smaller compressor for final heating / evaporation process before entering the condensers.

5. During evening hours, outside temperatures change to cooler conditions, therefore reducing the work load of the air conditioner. The cooler the inside home or business is, the less operation is needed. When operating during off sun hours, the outside cooler air will help reduce the condenser processing temperatures. The vacuum system will absorb the heat from the condenser and continue assisting the compressor.

6. Our thermal solar assist air conditioner provided with an attached thermal pressurized vacuum system that continuously helps heat Freon as it enters the smaller compressor. The heat from the outside air and condenser help heat the vacuum tubes, sending heated water or air into the thermal tank, helping to heat Freon before entering the compressor. The thermal tank is highly insulated with a copper coil that helps provides faster
