(7) Compressor assembly 20 includes a compressor 22 having a first tube 24 and a second tube 24a attached thereon. Compressor 22 may be a hermetically sealed compressor such as a rotor or a scroll type compressor. However, it should be understood that any compressor having a suitable motor that can be battery powered may be used for compressor 22. It should also be understood the compressor 22 may be used as an additional attachment for an existing compressor 51 having a belt drive 52 in a vehicle. Compressor 22 may be mounted to a vehicle using known means in the art such as fasteners, welding, and the like. Additionally, compressor 22 may also serve as a replacement to the existing compressor in a vehicle. The first tube 24 may be cylindrical in shape and may be made of a stainless-steel material. It should be understood by one of ordinary skill in the art that the first tube 24 may be made of any suitable material to withstand high-pressure and low-pressure gas flowing therein. The second tube 24a may be cylindrical in shape and may be made of a stainless-steel material. It should be understood by one of ordinary skill in the art that the second tube 24a may be made of any suitable material to withstand high-pressure and low-pressure gas flowing therein. In the present embodiment, the first tube 24 and the second tube 24a are included in compressor assembly 20. The first tube 24 is attached to an existing suction line 21 which is connected to an existing accumulator U of an existing A/C system in a vehicle. The second tube 24a is attached to an existing vapor line 23 of an existing A/C system in a vehicle. The first tube 24 is attached to the existing suction line 21 using a tee connector of the tee connectors 26. The second tube 26 is attached to the existing vapor line using an additional tee connector of the tee connectors 26. Tee connectors 26 as known in the art may be of a stainless-steel material and comprises a “T” shape. Additionally, check valves 28 may be mounted to compressor assembly 20 to allow the refrigerant inside of the first tube 24 and the second tube 24a to flow in one direction. In the present embodiment, one of the check valves 28 is disposed on existing vapor line 23. Additionally, another one of the check valves 28 is disposed on the second tube 24a which is connected to existing vapor line 23. Check valves 28 as known in the art may be made of a metal material to withstand high pressure and low pressure. In an additional embodiment, a liquid receiver filter drier 53 may be added as an attachment to A/C attachment system 10. The liquid receiver filter drier 53 is mounted to an existing line 54 that connects an existing condenser coil 55 to an existing evaporator coil 56. Additionally, an orifice 57 may be added between the liquid receiver filter drier 53 and the existing evaporator coil 56. Existing evaporator coil 56 includes a blower 58 attached thereon and existing condenser coil 55 includes a fan 59 attached thereon.

(8) Battery assembly 40 further includes an inverter 42. In one embodiment, inverter 42 may be attached to an existing battery 44 inside of a vehicle. In another embodiment, inverter 42 may be attached to an additional battery attachment to be added to a vehicle. It should be understood that inverter 42 is of a type that provides the necessary voltage to power compressor 22. These may include being attached to battery types such as wet cell car batteries, VRLA car batteries, and the like. Inverter 42 is used to provide the necessary voltage to compressor 22. This configuration allows a user to engage the A/C system in a vehicle without needing the engine within the vehicle to be running. In one embodiment, a user may engage A/C attachment system 10 using a switch located inside of the vehicle. In another embodiment, the existing A/C system in a car is replace using A/C attachment system 10. In this embodiment that A/C system of a car no longer relies on the engine of the vehicle. In another embodiment, a user may switch between using the existing A/C system in a car and A/C attachment system 10. In this embodiment, a user may utilize A/C attachment system 10 when the engine is turned off to cool the inside of a car. Afterwards, when a user desires to engage the engine of a vehicle, a user may then switch to using the existing A/C system of a vehicle. Such a configuration allows a user to save on the gas used for the vehicle.
