Air conditioning apparatus

Abstract

An air conditioning apparatus includes a casing having an inlet and an outlet, an airflow import device, a nozzle, two valves disposed at two ends of the nozzle, a vacuum pump connected through the nozzle, a connecting device, a heater, a humidifier, and an airflow export device. The airflow import and export devices are disposed at positions near the inlet and the outlet inside the casing. The nozzle includes an intake portion, a throat, and an exhaust portion connected sequentially and coaxially. A cross-sectional area of the intake portion decreases gradually from one end away from the throat to the other end close to the throat. A cross-sectional area of the throat is smaller than that of the exhaust portion. The connecting device is connected to the intake portion and the exhaust portion. The heater and the humidifier are disposed between the nozzle and the outlet.

         6 . The air conditioning apparatus according to  claim 2 , wherein an inner diameter of the throat is adjustable. 
     
     
         7 . The air conditioning apparatus according to  claim 2 , further comprising:
 a silencer tube disposed at an end of the exhaust portion of the supersonic nozzle.   
     
     
         8 . The air conditioning apparatus according to  claim 2 , wherein the connecting device comprises:
 a connecting pipe comprising two parts, wherein an end of one of the two parts is connected to communicate with a side wall of the intake portion and an end of the other one of the two parts is connected to communicate with a side wall of the exhaust portion; and   a pump connected with the other ends of the two parts of the connecting pipe.   
     
     
         9 . The air conditioning apparatus according to  claim 2 , further comprising:
 a first filter sieve disposed at a position near the inlet.   
     
     
         10 . The air conditioning apparatus according to  claim 2 , further comprising:
 a second filter sieve disposed after the heater and the humidifier and before the airflow export device.   
     
     
         11 . The air conditioning apparatus according to  claim 1 , further comprising:
 a water collection tank disposed below the exhaust portion in a gravity direction and connected to communicate with the exhaust portion, wherein a pressure in the water collection tank is substantially equal to a pressure in the exhaust portion.   
     
     
         12 . The air conditioning apparatus according to  claim 11 , further comprising:
 a filter module disposed between the water collection tank and the humidifier, wherein water in the water collection tank is adapted to flow to the humidifier after flowing through the filter module.
