The cold refrigerant 103 within the evaporator 109 will travel in between a plurality of parallel tubes 140 longitudinally disposed within the evaporator 109 configured to maintain liquid for freezing into solid and will continue to circulate within the evaporator 109 until the refrigerant exits the evaporator 109 by means of an suction line 134 which permits the refrigerant 103 to leave the evaporator 109 and casing 107 and be transmitted towards the compressor (not shown) where it is pressurized and cycles through the refrigeration system. The evaporator with dual-pipe heat exchange system 700 may be connected to or comprise a liquid inlet (not shown) configured above the evaporator 109 to permit liquid to be inserted into the tubes 140 within the evaporator 109.

[0047] Alternative embodiments are also disclosed whereby the refrigerant enters the evaporator with dual-pipe heat exchange system 700 at the bottom and travels in the opposite directions as depicted and described in FIG. 7.

[0048] FIG. 8 is an exemplary embodiment of a side-view of the evaporator with space reducers and dual-pipe heat exchange apparatus. In the illustrated embodiment, the evaporator with space reducers and dual-pipe heat exchange system 800 is comprised of a plurality of components, including an evaporator 109, a dual pipe tube 156, and an external casing 107 coving the evaporator from all sides. In one embodiment, dual pipe tube 156 is configured to transport hot refrigerant 101 through the outer pipe 157 through a liquid line 102 into a side chamber 104 between the outer perimeter of the side of evaporator 108 and along the inner perimeter of the side of casing 106. When the refrigerant 101 is traveling vertically downward through the side chamber 104 it is simultaneously traveling through the side heat exchange 105 within the evaporator with integrated space reducers and dual-pipe heat exchange system 800. The side chamber 104 may undergoing a heat exchange allowing the hot refrigerant to undergo a heat transfer and reduction in temperature due to thermal exchange with the side portion of the evaporator 108 which contains cold refrigerant. In one embodiment, the material makeup of the exterior sides of an evaporator may be steel, stainless steel or other metallic (conductive) materials.

[0049] Thereafter, the refrigerant 101 travels to a bottom chamber 120 configured between the outer bottom side of the evaporator 124 and the inner bottom side of the casing 122. When the refrigerant 101 travels through the bottom chamber 120 it is simultaneously traveling through the bottom heat exchange 121 within the evaporator with integrated space reducers with dual-pipe heat exchange system 800. Wherein the bottom chamber 120 is undergoing a heat exchange allowing the hot refrigerant 101 to undergo a heat transfer and reduction in temperature due to thermal exchange with the bottom side of the evaporator 124 which contains cold refrigerant.

[0050] Thereafter, the refrigerant 101 travels through a center chamber 118 configured through the center of a center space reducer 320 (shown in FIG. 4B) wherein the center space reducer is located between the exterior center wall of evaporator 115 and interior center cavity of the casing 117. In one embodiment, the center space reducer 320 may be comprised of a solid tube with a hollow center portion. In an alternative embodiment, the center space reducer 320 may be comprised of a hollow cylindrical tube with a hollow center portion. When the refrigerant 101 travels through the center chamber 118 it is simultaneously traveling through the center heat exchange 119 within the evaporator with integrated space reducers and dual-pipe heat exchange system 800. Wherein the center chamber 118 is undergoing a heat exchange allowing the hot refrigerant 101 to undergo a heat transfer and reduction in temperature due to the thermal exchange with exterior center wall of the evaporator 115 which contains cold refrigerant. In one embodiment, the center space reducer 320 is solid and does not permit refrigerant to travel through the center cavity 117.

[0051] Thereafter, the refrigerant 101 travels through the top chamber 110 configured between the exterior top side of the evaporator 114 and interior top side of the casing 112. When the refrigerant 101 travels through the top chamber 110 it is simultaneously traveling through the top heat exchange 111 within the evaporator with integrated space reducers and dual-pipe heat exchange system 800. Wherein the top chamber 110 is undergoing a heat exchange allowing the hot refrigerant 101 to undergo a heat transfer and reduction in temperature due to the thermal exchange with the bottom side of the evaporator 114 which contains cold refrigerant.

[0052] Thereafter, the refrigerant 101 exits the casing 107 by an outlet means 126 and travels towards the liquid feed solenoid valve 128 which controls the refrigerant 101 feed into the evaporator and allows the evaporator 109 to freeze in order to produce freeze/ice within the evaporator 109. The refrigerant 101 then bypasses the gas adjustable valve 130 (also known as expansion valve) where the refrigerant is pressurized and forced into the chamber room of the evaporator through a opening and enters the evaporator by an inlet means 132 wherein the refrigerant 101 will be substantially changed in form to a cold refrigerant 103 within the evaporator 109 due to change in pressure and colder temperatures within the evaporator 109. The cold refrigerant 103 within the evaporator 109 will travel vertically up in between a plurality of parallel tubes 140 longitudinally disposed within the evaporator 109 configured to maintain liquid for freezing into solid. The inside of the evaporator 109 will comprise a plurality of perimeter space reducers 310 and a center space reducer 320. The cold refrigerant 103 will continue to circulate within the evaporator 109 until the cold refrigerant 103 exits the evaporator 109 by means of an suction line 134 which permits the refrigerant to leave the evaporator 109 and casing 107 and be transmitted towards the compressor (not shown) where it is pressurized and cycles through the refrigeration system. The dual pipe tube 156 is configured to transport cold refrigerant 103 through the inner tube 159 from the suction line 134 into the compressor (not shown) to cycle through a refrigeration system (not shown). While the hot refrigerant 101 and the cold refrigerant 103 are simultaneously passing in opposite direction within the dual pipe tube 156, the outer pipe 157 may be acting as a heat exchange allowing the hot refrigerant 101 received from the refrigeration system (not shown) intended for the side chamber 104 to undergo heat transfer and reduction in temperature due to thermal exchange with the inner pipe 159 as the hot refrigerant 101 passes through the dual pipe 156.

[0053] Alternative embodiments are also disclosed whereby the refrigerant enters the evaporator with integrated space reducers and dual-pipe heat exchange system 800 at the bottom and travels in the opposite directions as depicted and described in FIG. 8.

[0054] FIG. 9 is an illustrative block diagram of dual pipe heat exchange apparatus. In one embodiment, the refrigeration system 408 provides hot refrigerant 101 into the outer pipe 157 of a dual pipe 156 directed towards the evaporator 109. In another embodiment, the evaporator 109 provides cold refrigerant 103 into the inner pipe 159 of a dual pipe 156 directed towards the refrigeration system 408.

[0055] FIG. 10 is an illustrative mid-view prospective of a dual pipe heat exchange apparatus. In one embodiment, the dual pipe 156 is comprised of an outer pipe 157 and an inner pipe. The outer pipe is comprised of a chamber between the exterior of the inner pipe 159 and the interior of the outer pipe 157. The inner pipe is comprised of a chamber comprised wholly of the inner pipe 159 cavity. The outer pipe is comprised of hot refrigerant 101 directed towards the evaporator. The inner pipe is comprised of cold refrigerant 103 directed away from the evaporator.
