TECHNICAL FIELD

The present invention in general relates to a system and method used in hybrid split air conditioner, more particularly present subject matter relates to hybrid split air conditioner which runs on the water.
BACKGROUND
Most people use air conditioners to stay more comfortable in their homes or offices during hot summers. Air conditioner system works by ducting air across the colder, heat-absorbing side of a thermostatically controlled refrigeration system and directing it back into the living environment. The heat generated inside the air conditioner is carried away via an exhaust unit which is present at out of a window. The heat emitted by the air conditioner may increase temperature of the surrounding environment.
The cooling agents used in air conditioner are very harmful to the environment. The radiations of the such a harmful cooling agent in the environment cause damage to the ozone layer and which increases the rate of the global warming. This may create problem for future generations.
The air conditioners which are available in market are very expensive. An initial and running cost of the air conditioners is very high. The air conditioners consume a lot of electricity and maintenance cost is also higher. This creates financial disadvantages to the users as well as increases load on producing energy resources.
Thus, there is a long-standing need of lowering down the carbon emissions done by air conditioners (AC) and to produce low power consuming, cost effective, highly efficient air conditioners.
