Abstract:
A sectional evaporator system having at least four sections for vaporizing a refrigerant passing through a thermal transfer cycle, said sectional evaporator system to be placed in an air stream having a width generated by an air supply, and said sectional evaporator system comprising in combination: first, second, third, fourth evaporator sections positioned in the air stream such that the first evaporator section is positioned edge-to-edge with the fourth evaporator section, both of which are positioned across the width of the air stream upstream of the second evaporator section, the second evaporator section is upstream of the third evaporator section, where all the sections being in sequential fluid communication with each other, such that the refrigerant passes first through the first evaporator section, then secondly through the second evaporator section, then thirdly through the third evaporator section, and then fourthly through the fourth evaporator section, thereby allowing sequential flow through the evaporator system, and thereby more fully approaching a true thermal counterflow heat exchange evaporator system.
