Cryogenic exhaust gas air conditioner

Abstract

An air conditioner apparatus includes an exhaust pipe having a first end in communication with exhaust gas from an exhaust generating device disposed in a first atmosphere with a first temperature, and a second end discharging the exhaust gas to a second atmosphere with a second temperature; an inlet pipe substantially surrounding the exhaust pipe, the inlet pipe spaced apart from the exhaust pipe for providing a space therebetween and having a first end in communication with the first atmosphere and a second end in communication with the second atmosphere and through which the second atmosphere is introduced into the space; and a guide assembly disposed in the space for guiding the second atmosphere through the space for heat transfer with the exhaust gas moving through the exhaust pipe.

1 . An air conditioner apparatus, comprising:
 an exhaust pipe having a first end in communication with exhaust gas from an exhaust generating device disposed in a first atmosphere with a first temperature, and a second end discharging the exhaust gas to a second atmosphere with a second temperature;   an inlet pipe substantially surrounding the exhaust pipe, the inlet pipe spaced apart from the exhaust pipe for providing a space therebetween and having a first end in communication with the first atmosphere and a second end in communication with the second atmosphere and through which the second atmosphere is introduced into the space; and   a guide assembly disposed in the space for guiding the second atmosphere through the space for heat transfer with the exhaust gas moving through the exhaust pipe.   
     
     
         2 . The apparatus of  claim 1 , wherein the guide assembly comprises at least one fin arranged in the space to direct a flow of the second atmosphere through the space. 
     
     
         3 . The apparatus of  claim 1 , wherein the guide assembly comprises a plurality of fins in spaced apart relationship arranged in the space to direct a flow of the second atmosphere through the space. 
     
     
         4 . The apparatus of  claim 1 , wherein the guide assembly comprises a helical member arranged in the space for providing a plurality of helical pathways circumscribing the space and through which the second atmosphere flows. 
     
     
         5 . The apparatus of  claim 1 , wherein the exhaust generating device comprises a freezer. 
     
     
         6 . The apparatus of  claim 1 , wherein the exhaust generating device comprises a heater. 
     
     
         7 . The apparatus of  claim 6 , wherein the heater comprises an oven. 
     
     
         8 . The apparatus of  claim 1 , wherein the second atmosphere is external to a location of the first atmosphere. 
     
     
         9 . The apparatus of  claim 1 , wherein the second end of the inlet pipe is open to an elevated region of the first atmosphere. 
     
     
         10 . The apparatus of  claim 1 , further comprising insulation disposed at an exterior of the inlet pipe. 
     
     
         11 . The apparatus of  claim 1 , further comprising a first blower in communication with the second end of the exhaust pipe for moving the exhaust gas through the exhaust pipe, and a second blower in communication with the first end of the inlet pipe for moving the second atmosphere through the inlet pipe. 
     
     
         12 . The apparatus of  claim 1 , wherein the second temperature is greater than the first temperature.
