Method for recycling energy from compressor outlet, and air conditioner

Abstract

A method for recovering and using energy from a fluid exiting an outlet of a compressor in an air conditioning system, the method including: disposing an ejector between a compressor and a condenser of an air conditioning system, the ejector including a first inlet for receiving a working fluid and a second inlet for receiving an ejection fluid; connecting the first inlet of the ejector to an outlet of the compressor; connecting an outlet of the ejector to an inlet of the condenser; and connecting the second inlet of the ejector to an evaporator of the air conditioning system.

The invention claimed is: 
     
         1 . A method for recovering and using energy from a fluid exiting an outlet of a compressor in an air conditioning system, the method comprising:
 a) disposing an ejector between a compressor and a condenser of an air conditioning system, the ejector comprising a first inlet for receiving a working fluid and a second inlet for receiving an ejection fluid;   b) connecting the first inlet of the ejector to an outlet of the compressor;   c) connecting an outlet of the ejector to an inlet of the condenser; and   d) connecting the second inlet of the ejector to an evaporator of the air conditioning system.   
     
     
         2 . The method of  claim 1 , wherein the outlet of the compressor is connected in parallel to a plurality of ejectors. 
     
     
         3 . The method of  claim 1 , wherein the outlet of the compressor is connected in series to a plurality of ejectors. 
     
     
         4 . The method of  claim 1 , wherein the outlet of the compressor is connected to the ejectors in a mixed connection type; and the mixed connection type comprises a serial connection and a parallel connection. 
     
     
         5 . The method of  claim 1 , wherein the second inlet of the ejector for receiving an ejection fluid is connected to one or more evaporators. 
     
     
         6 . The method of  claim 1 , wherein the outlet of the ejector is provided with a four-way valve, and the four-way valve is connected to the condenser and the evaporator. 
     
     
         7 . An air conditioning system, comprising:
 a) a compressor, the compressor comprising an outlet;   b) an ejector, the ejector comprising: a first inlet for receiving a working fluid, a second inlet for receiving an ejection fluid, and an outlet;   c) a condenser, the condenser comprising an inlet, and an outlet; and   d) an evaporator, the evaporator comprising an inlet, a first outlet, and a second outlet;   
       wherein
 the ejector is disposed between the compressor and the condenser; 
 the outlet of the compressor is connected to the first inlet of the ejector for receiving the working fluid; 
 the outlet of the ejector is connected to the inlet of the condenser; 
 the outlet of the condenser is connected to an inlet of the evaporator; and 
 the first outlet of the evaporator is connected to the second inlet of the ejector for receiving the ejection fluid and the second outlet of the evaporator is connected to the compressor. 
 
     
     
         8 . The system of  claim 7 , wherein the second inlet of the ejector for receiving an ejection fluid is connected to one or more evaporators. 
     
     
         9 . The system of  claim 7 , wherein the outlet of the ejector is provided with a four-way valve; and the four-way valve is connected to the condenser and the evaporator. 
     
     
         10 . The system of  claim 7 , wherein the outlet of the compressor is connected to a plurality of the ejectors in series, in parallel, or both in series and in parallel.
