Waste heat recycling and gain system

Abstract

A waste heat recycling and gain system includes a waste heat exchanging device disposed beneath a hot water supplier to collect the heat of the hot water, a primary heat exchanging device coupled between the supplier and the waste heat exchanging device to heat the hot water before supplying to the supplier, and an auxiliary heat exchanging device coupled to the waste heat exchanging device to decrease a temperature of the water before flowing into the waste heat exchanging device and to preheat a heat medium that flows through the auxiliary heat exchanging device, in order to effectively recycle or reuse the heat of the waste hot water and to save our energy.

1 . A waste heat recycling and gain system comprising:
 a supplier for outwardly supplying a hot water,   a waste heat exchanging device disposed beneath said supplier to collect a heat of the hot water supplied from said supplier, and including an inlet port and an outlet port,   a first heat exchanging device coupled between said supplier and said outlet port of said waste heat exchanging device to heat the hot water before supplying to said supplier, and   a second heat exchanging device coupled to said inlet port of said waste heat exchanging device to decrease a temperature of the water that flows through said second heat exchanging device, and to preheat a heat medium that flows through said second heat exchanging device.   
     
     
         2 . The waste heat recycling and gain system as claimed in  claim 1 , wherein said waste heat exchanging device includes a housing disposed beneath said supplier to collect the hot water supplied from said supplier, and a waste heat exchanging member disposed in said housing to collect the heat of the hot water. 
     
     
         3 . The waste heat recycling and gain system as claimed in  claim 1 , wherein said first heat exchanging device includes a first heat exchanging member coupled between said supplier and said outlet port of said waste heat exchanging device, and a second heat exchanging member disposed beside said first heat exchanging member for forming said first heat exchanging device. 
     
     
         4 . The waste heat recycling and gain system as claimed in  claim 3 , wherein said second heat exchanging device includes a third heat exchanging member coupled to said inlet port of said waste heat exchanging device, and a fourth heat exchanging member disposed beside said third heat exchanging member for forming said second heat exchanging device. 
     
     
         5 . The waste heat recycling and gain system as claimed in  claim 4 , wherein a compressor is coupled in series between said second heat exchanging member of said first heat exchanging device and said fourth heat exchanging member of said second heat exchanging device to form a heat device. 
     
     
         6 . The waste heat recycling and gain system as claimed in  claim 5 , wherein said heat device includes a throttle valve coupled between said second heat exchanging member of said first heat exchanging device and said fourth heat exchanging member of said second heat exchanging device. 
     
     
         7 . The waste heat recycling and gain system as claimed in  claim 6 , wherein said heat device includes an evaporator coupled between said throttle valve and said fourth heat exchanging member of said second heat exchanging device.
