Air conditioner

Abstract

An air conditioner that acquires energy from a high pressure gas includes a gas storage device, a pneumatic engine, a compressor, a cooling system, and a control module. The gas storage device supplies the high pressure gas. A duct guides the high pressure gas into an engine room of the pneumatic engine. The pneumatic engine transforms the high pressure gas into a kinetic energy for output. The compressor is connected to a kinetic energy output of the pneumatic engine. The pneumatic engine drives the compressor to circulate a refrigerant within the cooling system.

What is claimed is: 
     
         1 . An air conditioner, comprising:
 a gas storage device, for providing compressed high pressure gas;   a pneumatic engine, connected to the gas storage device, for transforming the high pressure gas into a kinetic energy for output;   a cooling system; and   a compressor, connected to a kinetic energy output of the pneumatic engine, wherein the pneumatic engine drives the compressor to circulate a refrigerant within the cooling system.   
     
     
         2 . The air conditioner of  claim 1 , wherein the gas storage device comprises a liquid nitrogen storage device, a liquid oxygen storage device, and an evaporation chamber, the liquid nitrogen storage device stores liquid nitrogen, the liquid oxygen storage device stores liquid oxygen, after evaporation the liquid nitrogen and the liquid oxygen are stored in the evaporation chamber for propelling the pneumatic engine. 
     
     
         3 . The air conditioner of  claim 2 , further comprising a regulating valve in between the liquid nitrogen storage device and evaporation chamber, a regulating valve in between the liquid oxygen storage device and the evaporation chamber, and a regulating valve in between the evaporation chamber and the pneumatic engine. 
     
     
         4 . The air conditioner of  claim 1 , wherein a valve is installed in between the gas storage device and the pneumatic engine, and the valve adjusts a pressure and flow of the high pressure gas entering the pneumatic engine. 
     
     
         5 . The air conditioner of  claim 4 , further comprising a control module, wherein the control module comprises a gas pressure monitoring unit and an electromagnetic valve control unit, the gas pressure monitoring unit monitors a pressure inside the gas storage device, and the electromagnetic valve control unit drives the valve in order to adjust a pressure and flow of the high pressure gas supplied by the gas storage device to the pneumatic engine. 
     
     
         6 . The air conditioner of  claim 5 , wherein the air conditioner is a cooler, a heater, or a cooler/heater. 
     
     
         7 . The air conditioner of  claim 1 , further comprising a gas refilling device, wherein the gas refilling device comprises a first compressor, the gas storage device comprises at least a first gas storage device and a second gas storage device, an inner pressure of the first gas storage device is higher than an inner pressure of the second gas storage device, a pressure regulating valve is installed in between the first gas storage device and the second gas storage device, the second gas storage device supplies the high pressure gas to the pneumatic engine, a valve is installed in between the second gas storage device and the pneumatic engine, and the pneumatic engine drives the first compressor to supply gas to the second gas storage device. 
     
     
         8 . The air conditioner of  claim 7 , wherein the gas refilling device further comprises a generator and a second compressor, the gas storage device comprises at least a first gas storage device and a second gas storage device, an inner pressure of the first gas storage device is higher than an inner pressure of the second gas storage device, a pressure regulating valve is installed in between the first gas storage device and the second gas storage device, the second gas storage device supplies the high pressure gas to the pneumatic engine, a valve is installed in between the second gas storage device and the pneumatic engine, the pneumatic engine drives the generator to generate electricity and supply the generated electricity enable the second compressor supplies gas to the second gas storage device. 
     
     
         9 . The air conditioner of  claim 8 , wherein the generator supplies electricity to a cooling fan and a control module of the air conditioner. 
     
     
         10 . The air conditioner of  claim 1 , wherein the air conditioner is a cooler, a heater, or a cooler/heater.
