DESC:FIELD OF THE INVENTION
This invention relates to the field of air conditioning to energy savings and to increase cooling efficiency. More particularly, the present invention related to increasing efficiency of the condenser and compressor by using solar energy, evaporative cooling, and subcooling technologies
BACKGROUND OF THE INVENTION
Global warming causes an increase in the temperature of the earth. Therefore summer is getting hotter and winters are getting less cold. Because of hotter summer, the demand for air conditioners has increased. With the increase in demand for air conditioners, energy demand also increased. The compressor runs continuously and consumes huge energy. The conventional air conditioning uses a fixed speed heat pump/compressor which runs constantly at a rated speed all the time dragging a certain amount of power continuously. Once attaining the set temperature the compressor trips and when it starts again it drags
a heavy amount of starting current resulting in jerk load. Some existing methods of air conditioner have been developed from time to time to reduce energy.
US10024586B2 discloses a system for pre-cooling inlet air to an air conditioning condenser unit using evaporative cooling. The system includes a support frame, a set of removable mesh panels for passing through inlet air, and a water disposal system for wetting the mesh panels actuated by the operation of the air conditioning condenser unit.
US20120125027A1 discloses an evaporative pre-cooling system for increasing the efficiency of a residential air conditioner condensing unit utilizing a wet medium in contact with low velocity moving air allowing evaporation to occur across the wet medium thereby reducing the associated dry-bulb air temperature of the air moving across the wet pad as the air absorbs moisture. In the present invention, the embodiment of the pre-cooling apparatus encapsulates the condensing unit with a wet cellulose media, water not absorbed during the evaporation cycle is recycled, and water generated by the evaporator coil is discharged into the sump to further reduce tap water consumption. In the embodiment of the present invention, the wet pre-cool mode is thermostatically in parallel with the electrical circuit energizing the pre-cooler system in tandem with the air conditioning compressor motor. The embodiment of the pre-cooling apparatus is constructed of cellulose evaporative pads, plastic top, plastic upper distribution channels, plastic lower water recovery channels, polyvinyl chloride (PVC) piping and fittings for water distribution, plastic frame, PVC for water drains, plastic sump reservoir, and plastic close-off panels and a water pump providing total recyclability of the embodiment of the complete evaporative pre-cooler enclosure apparatus..
The existing methods lack in the invention as the existing inventions are not able to overcome the problem associated with energy consumption. Thus there is a need for the present invention to overcome the above mention problems.

SUMMARY OF THE INVENTION
The present invention relates to a hybrid air conditioning system for low energy consumption The present invention includes an indoor unit, a suction pipe, a discharge pipe an outdoor unit, a water tank, and an expansion valve. The indoor unit is an evaporator that cools the indoor heated air. The indoor unit includes an evaporator coil. The evaporator coil exchanges heat from the indoor heated air. Thus refrigerant inside the evaporator coil becomes superheated vapor refrigerant. The suction pipe and the discharge pipe are connected to the evaporator coil of the indoor unit. The outdoor unit includes a casing, a condenser coil, a compressor, a honeycomb pad, a water dripping channel, a cylinder, an extended condenser coils and a condenser fan. The compressor is connected to the evaporator coil of the indoor unit through the suction pipe. The compressor compresses the superheated refrigerant coming from the evaporator coil of the indoor unit and passes to the condenser coil. The honeycomb pad is attached to the back of the condenser coil. The water dripping channel is installed on the top of the honeycomb pad. The water dripping channel drips water on the honeycomb pad, thus cooling down the ambient temperature of air passes through it. Thus cools down the superheated vapor refrigerant to the saturated liquid refrigerant. The condenser fan is placed behind the condenser coil inside the casing to draw out the heat. Herein, by using the honeycomb pad and the water dripping channel the ambient temperature of the condenser coil cools down. Thus convert superheated vapor refrigerant to the saturated liquid refrigerant efficiently, thus saves a large amount of energy. The water tank is placed at back side of the outdoor unit. The water pump is dipped into the water tank. The water pump pumps water to the water dripping channel through water pipe. The water from water tank is made to pass through the cylinder using water pump with the help of the pipe and after that water is poured onto the honeycomb pad through the water dripping channel. The extended condenser coil is in shape of spiral tubes in which refrigerant from condenser coil is made to pass through. The extended condenser coil is placed inside a cylinder in which water from water tank using water pump with the help of the water pipe is made to pass through and after that water is poured onto the honeycomb pad. Through the discharge pipe one end of the extended condenser coil is connected to the condenser coil and other end of the extended condenser coil is connected to the evaporator coil of the indoor unit. Herein, the extended condenser coil cools down the saturated liquid refrigerant to the sub-cooled refrigerant, thus increasing the efficiency of the system and reducing energy consumption. The expansion valve is mounted on the discharge pipe coming from extended condenser coil and the sub-cooled refrigerant expands inside the expansion valve before entering the evaporator coil of the indoor unit. Herein, with help of the honeycomb pad and the extended condenser, the refrigerant is cooled down to subcooling temperature that lowers the load on the compressor and the condenser coil thus decreasing energy consumption.
