DESC:Title of the Invention
AN AIR CONDITIONING SYSTEM WITH BUILT-IN STORAGE FOR HEATING AND COOLING OF SPACE
Field of the Invention
The present invention relates generally to air conditioning systems, and, more particularly, to air conditioning systems with built-in storage for heating and cooling of space.
Background of the Invention
Air conditioning systems (also popularly known as air-conditioners) used for cooling in summer and heating in winter are available in the market. Also, some of the air conditioning systems absorb the heat generated by equipment, machines, and the like.
The space to which the air conditioning systems provide the heating/cooling are generally air tight to avoid the air leakage. During the time of power failure, the existing air conditioning systems are powered off and the internal environment becomes very suffocated and reduces the efficiency of human beings. Also, the equipment installed otherwise to be operated on an alternate source like DG, inverter, and the like.
In general air conditioners that are available in the market are being used for cooling in summer and heating in winter or to absorb the heat generated by equipment, machines etc.
The space for which air-conditioners are placed is generally airtight to avoid air leakage. During the time of power failure, the existing air-conditioners are off and the internal environment becomes very suffocated and reduces the efficiency of human beings and equipment installed otherwise to be operated on an alternate source like DG, inverter etc.
Accordingly, what is required is an air conditioning system that has a backup energy mechanism for providing heating/cooling to a space in cases of power failure and other emergency situations.
None of the prior art either alone or in combination with one another disclose what the present invention has disclosed. Present invention is air conditioning system with built-in storage for heating and cooling of space.
