1. Technical Field
The invention relates generally to an air conditioner, and more particularly, to a pneumatic air conditioner that consumes high pressure gas.
2. Related art
A conventional air conditioner is also called a cooler/heater. Its compressor is driven by a motor, and the motor is consumes electricity. The compressor allows a refrigerant to circulate within a cooling system, enabling heat exchange to heat up or cool down the air. However, the electricity probably comes from a nuclear power plant or a thermal power plant that burns fossil fuel. The pollution and greenhouse effect caused by these conventional methods of generating electricity is an urgent problem that human must resolve as soon as possible.
In additional, currently there is no solution to the radioactive pollution problem of nuclear power. Moreover, the costs of fossil fuel have been rising and in the near future it might become unpractical or too expensive to use fossil fuel to generate electricity. Furthermore, the exhaust gas resulting from the burning of fossil fuel is not only odorous but also will lead to some health problems.
Moreover, it's likely that there won't be unlimited supply of electricity. In some places where there is no electricity or only unstable supply of electricity, even the richest people may not be able to enjoy the benefits of having an air conditioner.

Further description of the structural details of a pneumatic engine is omitted herein. Because a pneumatic engine is driven by compressed gas, the engine will not result in problems such as environment pollution and global warming.

The gas pressure monitoring unit 161 monitors the gas pressure inside the gas storage device 11. The gas pressure monitoring unit 161 sends a warning signal to the control module 16 when the detected pressure is too low. The electromagnetic valve control unit 162 drives the valve 17 to adjust the pressure and flow of the high pressure gas provided by the gas storage device 11 to the pneumatic engine 10 so as to stabilize the quality of power generation.
The embodiments use high pressure gas to supply energy to the pneumatic engine 10, and use the kinetic energy outputted by the pneumatic engine 10 to drive the compressor 12 to circulate the refrigerant within the cooling system 13.
The pneumatic engine 10 can be a reciprocal type or a rotational type engine. It can have a single cylinder or a plurality of cylinders arranged horizontally or in a V-shape.
In the embodiment shown in
The gas storage device 11 of this embodiment has a liquid nitrogen storage device 110, a liquid oxygen storage device 120, and an evaporation chamber 130. The liquid nitrogen storage device 110 stores liquid nitrogen. The liquid oxygen storage device 120 stores liquid oxygen.

Please refer to
Under a first alternative, the air conditioner 100 further includes a gas refilling device 2. The gas refilling device 2 includes a first compressor 22. The gas storage device 11 has at least a first gas storage device 111 and a second gas storage device 112. The inner pressure of the first gas storage device 111 is higher than that of the second gas storage device 112. In between the first gas storage device 111 and the second gas storage device 112 there is a pressure regulating valve 271.

Please refer to
The second gas storage device 112 should supply sufficient high pressure gas to drive the pneumatic engine 10.
As shown in
As shown in
Although the second compressor 21 and the first compressor 22 can refill some compressed gas, it's not enough to compensate for the high pressure gas used to propel the pneumatic engine 10. To deal with this problem, the high pressure gas stored in the first gas storage device 111 can be used to refill the second gas storage device 112 to compensate for the consumed high pressure gas.
The pressure regulating valve 271 is installed in between the second gas storage device 112 and the first gas storage device 111 of high inner pressure. When the inner pressure of the second gas storage device 112 is lower than a predetermined minimum, the pressure regulating valve 271 will open automatically. The opened pressure regulating valve 271 allows high pressure gas to flow from the first gas storage device 111 into the second gas storage device 112. When the inner pressure of the second gas storage device 112 is higher than a predetermined maximum, the pressure regulating valve 271 will close automatically. The pressure regulating valve 271 ensures that the inner pressure of the second gas storage device 112 is between the predetermined maximum and minimum. This pressure range is suitable for propelling the pneumatic engine 10. Of course, the inner pressure of the first gas storage device 111 will reduce gradually. If the pressure is too low, an external gas-filling device must be used to refill high pressure gas into the first gas storage device 111.
