摘要： PURPOSE:To unify heat transfer performance in the lengthwide direction of a heat transfer tube by a method wherein two rows or more of heat transfer tubes for promoting the operation of operating liquid in the upper or lower part of a system are arranged and one part of the tubes is used as going tubes while remaining tubes are used as returning tubes. CONSTITUTION:Upper heat transfer tubes are arranged in two rows 3a1, 3a2 and lower heat transfer tubes are arranged in two rows 3c1, 3c2 while one end of the tubes is turned to use the heat transfer tubes in the row 3a1 as a going tube and use the other heat transfer tube in the row 3a2 as a returning tube. The uneven property of performances at the inlet side and the outlet side of the heat transfer tube is improved remarkably and unified heat transfer performance may be shown along the whole length of the heat transfer tube. As a result, the adhering degree of ice upon space cooling operation is equalized in the lengthwise direction of the heat transfer tube, whereby ice 6 may be frozen with the same growing speed along the whole length of the tube. The same thing may be said in space heating operation.
