Heat exchanging device having continuously operatable compressor

Abstract

A heat exchanging device includes two piping members coupled between a compressor and a evaporator, a condenser coupled to one of the piping members, and two control valves for controlling the medium to flow through either of the piping members. A tubing may receive a heat exchanging fluid and may supply the heat exchanging fluid to the evaporator and to heat exchange with the medium. The control valves may control the medium to flow either through the condenser or to flow through the other piping member without through the condenser and the capillary tube, for allowing the compressor to be continuously operated without being stopped and for increasing the working life of the compressor.

1 . A heat exchanging device comprising: 
 a first piping member for receiving and circulating a medium therein,    a compressor coupled to said first piping member for pumping and circulating the medium,    an evaporator coupled to said first piping member and coupled to said compressor for heat exchanging purposes,    a second piping member and a third piping member coupled between said compressor and said evaporator and parallel to each other,    a condenser and a capillary tube coupled to said second piping member for heat exchanging purposes,    a first control valve coupled to said second piping member for controlling the medium to flow through said second piping member and said condenser and said capillary tube,    a second control valve coupled to said third piping member for controlling the medium to flow through said third piping member without through said second piping member and said condenser and said capillary tube, and    a tubing for receiving a heat exchanging fluid, said tubing being coupled to said evaporator for supplying the heat exchanging fluid to said evaporator and to heat exchange with the medium, and    said first control valve being actuated to control the medium to flow through said second piping member and said condenser and said capillary tube when said second control valve is switched off, and said second control valve being actuated to control the medium to flow through said first piping member without through said second piping member and said condenser and said capillary tube when said first control valve is switched off.    
   
   
       2 . The heat exchanging device as claimed in  claim 1 , wherein a reservoir is coupled to said first piping member for receiving and storing the medium.  
   
   
       3 . The heat exchanging device as claimed in  claim 1 , wherein a pressure detector is coupled to said first piping member for detecting a pressure of the medium through said first piping member.  
   
   
       4 . The heat exchanging device as claimed in  claim 1 , wherein a window is coupled to said second piping member for viewing and watching a flowing of the medium through said second piping member.  
   
   
       5 . The heat exchanging device as claimed in  claim 1 , wherein a drying device is coupled to said second piping member for drying the medium.  
   
   
       6 . The heat exchanging device as claimed in  claim 1 , wherein a pressure detector is coupled to said second piping member for detecting a pressure of the medium in said second piping member.  
   
   
       7 . The heat exchanging device as claimed in  claim 1 , wherein a fan device is disposed beside said condenser for facilitating a heat exchanging of said condenser.  
   
   
       8 . The heat exchanging device as claimed in  claim 1 , wherein an object is coupled to said tubing for being cooled by the heat exchanging fluid.  
   
   
       9 . The heat exchanging device as claimed in  claim 1 , wherein a pump is coupled to said tubing for pumping and circulating the heat exchanging fluid through said tubing.  
   
   
       10 . The heat exchanging device as claimed in  claim 1 , wherein a tank is coupled to said tubing for receiving and storing the heat exchanging fluid.  
   
   
       11 . The heat exchanging device as claimed in  claim 10 , wherein a temperature sensor is coupled to said tank to detect a temperature of the heat exchanging fluid within said tank.  
   
   
       12 . The heat exchanging device as claimed in  claim 10 , wherein a heater is coupled to said tank to heat and maintain the temperature of the heat exchanging fluid in said tank.  
   
   
       13 . The heat exchanging device as claimed in  claim 1 , wherein a flow control device is coupled to said tubing for controlling a flowing of the heat exchanging fluid through said tubing.
