Heating and cooling system

Abstract

A heating and cooling system includes a compressor for pumping a heat medium through a tubing device, a primary heat exchanger coupled to the compressor, a control device coupled to the primary heat exchanger and coupled to a intermediate heat exchanger to control the intermediate heat exchanger either to dissipate heat or to absorb heat. Another control device is coupled to the intermediate heat exchanger and coupled to the compressor and a secondary heat exchanger, to control the heat medium from the intermediate heat exchanger either to flow through the secondary heat exchanger or to directly flow into the compressor without flowing through the secondary heat exchanger.

1 . A heating and cooling system comprising: 
 a compressor for pumping a heat medium through a tubing device,    a first heat exchanger coupled to said compressor, for receiving compressed heat medium from said compressor,    a first control device coupled to said first heat exchanger,    a second heat exchanger coupled to said first control device, and arranged to have said first control device coupled between said first heat exchanger and said second heat exchanger, said first control device being provided to control said second heat exchanger either to dissipate heat or to absorb heat,    a second control device coupled to said second heat exchanger and coupled to said compressor, and    a third heat exchanger coupled to said second control device,    said second control device being provided to control the heat medium from said second heat exchanger either to flow through said third heat exchanger or to directly flow into said compressor without flowing through said third heat exchanger.    
   
   
       2 . The heating and cooling system as claimed in  claim 1 , wherein said first heat exchanger is provided for generating an output heat medium.  
   
   
       3 . The heating and cooling system as claimed in  claim 1 , wherein said third heat exchanger is provided for generating an output cold medium.  
   
   
       4 . The heating and cooling system as claimed in  claim 1 , wherein said first control device includes a control valve and a throttle device coupled in parallel to each other, in order to control said second heat exchanger either to dissipate the heat or to absorb the heat.  
   
   
       5 . The heating and cooling system as claimed in  claim 1 , wherein said second control device includes a control valve and a throttle device coupled in parallel to each other, in order to control the heat medium either to flow through said third heat exchanger or to directly flow into said compressor.
