摘要： PROBLEM TO BE SOLVED: To solve such a problem that in a conventional refrigeration cycle device, a fin used in an evaporator has not been subjected to surface processing for improving the performance in frost formation, and moisture in air is therefore condensed to adhere on a surface of the evaporator as droplets when a refrigerant of 0°C or lower is supplied to the evaporator to cause frost formation on the surface of the evaporator, and then a position of the adhesion is not specified to cause the droplets to coalesce easily and coagulate after growing as large droplets, thereby increasing air trunk pressure loss due to unevenness of a frost layer to deteriorating the performance in frost formation.SOLUTION: A large number of pores are provided on the fin used in the evaporator with a predetermined relative distance and diameter, and thereby droplets and ice droplets are formed on ridge lines of the pores on a cooling surface (evaporator) when the moisture in air causes frost formation on the surface of the evaporator. Accordingly, condensed liquid droplets hardly coalesce, the droplets become small in coagulation, and the thin frost layer is formed to reduce the air truck pressure loss. As a result, the performance in frost formation is improved and energy is saved.
摘要翻译：解决的问题为了解决现有的制冷循环装置中的问题，在蒸发器中使用的翅片没有进行用于提高霜冻性能的表面处理，因此将空气中的水分冷凝至当向蒸发器供应0℃或更低的制冷剂时，在蒸发器的表面上粘附在蒸发器的表面上，以在蒸发器的表面上形成结霜，然后没有规定粘附位置使液滴聚结容易生长后会凝结，大量液滴凝结，从而增加由于霜层不均匀引起的空气干扰压力损失，降低了霜冻性能。解决方案：在蒸发器中用于预定相对距离和直径的翅片上提供大量孔，并且由此在冷却表面（蒸发器）上的孔的脊线上形成液滴和冰滴空气中的水分会导致蒸发器表面产生结霜。因此，冷凝的液滴几乎不会聚结，液滴在凝结中变小，形成薄层霜以减少空气卡车的压力损失。结果，改善了霜冻形成的能力，节约了能源。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem in a conventional refrigerating cycle device wherein a fin used in an evaporator is not subjected to surface treatment for improving performance during frosting, so that when a refrigerant of 0°C or less is supplied to the evaporator and frosting occurs on the surface of the evaporator, because the position where moisture in air condenses and adheres on the surface of the evaporator as water droplets is not predetermined, uniting of water droplets easily occurs to become large water drops that solidify thereafter, and therefore, pressure loss in an air duct becomes large by irregularities of a frost layer, and performance during frosting is deteriorated. SOLUTION: By providing a plurality of micropores in the fin used in the evaporator, when frosting occurs on the surface of the evaporator, uniting of condensed liquid droplets hardly occurs on the cooling surface (evaporator), the water droplets when solidification occurs become small, and a clean frost layer is formed. Thereby, pressure loss in the air duct becomes small, performance during frosting is improved, and energy is saved. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题为了解决传统的制冷循环装置中的问题，其中在蒸发器中使用的翅片不进行表面处理以改善结霜期间的性能，使得当供应0℃或更低的制冷剂时蒸发器发生结霜，因为当水滴不是预定时，空气中的水分会冷凝并附着在蒸发器表面上的位置，容易发生水滴的结合，从而变成大的水滴，此后会固化因此，由于霜层的不规则性，导风管内的压力损失变大，结霜时的性能劣化。解决方案：通过在蒸发器中使用的翅片中设置多个微孔，当在蒸发器的表面上发生结霜时，在冷却表面（蒸发器）上几乎不发生冷凝液滴的结合，凝固发生时的水滴变小，形成清洁的霜层。因此，空气管道中的压力损失变小，结霜时的性能提高，能量节省。版权所有（C）2010，JPO＆INPIT
