摘要： In a refrigerating cycle (air conditioner) using mixture refrigerant, a mixing ratio of the refrigerant in a refrigerant circuit is measured by a mixing ratio detector, and a controller receives the detection signal to open a control valve when the mixing ratio of a high boiling-point refrigerant component is low, whereby the high boiling-point refrigerant stocked in a liquid reservoir is returned to the refrigerant circuit. The high boiling-point refrigerant which is supplied from the liquid reservoir through the opening operation of the control valve is supplied from a low pressure side of a compressor into the refrigerant circuit to keep the mixing ratio of the refrigerant circulating in the refrigerant circuit to a predetermined value, thereby preventing abnormal increase of pressure of the refrigerant due to variation of the mixing ratio.

摘要： In a heat exchanger comprising a number of multilayered fins, and a refrigerant pipe arranged in the meandering form in the fins, and an air conditioner having the heat exchanger, each of the fins has a corrugated portion formed in an air-flow direction thereon, which has at least two wavelike portions for producing a turbulent flow of air having such strength that a temperature boundary layer of the air is broken, but resistance against to the air flow is not excessively high. Each wavelike portion may be designed to have a triangular section or a trapezoidal section, and a flat portion may be disposed between the wavelike portions.

摘要： A heat exchanger having an improved and substantially uniform heat exchange efficiency, provided with a plurality of plate fins each of which has tube inserting bores arranged in a staggered manner, and heat transfer tubes inserted through these bores, a plurality of each of the fins which are between the tubes being cut doubly to a small width and raised so as to form louver elements so that the louver elements cross a flow of the air stream. The root portions of the louver elements are positioned so as to surround the inserted portions of the tubes, the louver elements consisting of central louver elements formed on both sides of the center line of the row of the tubes, and a plurality of rows of divisional louver elements formed on both sides of the central louver elements with base portions left on the regions of the fin which are on a line crossing the mentioned center line, and the length of the divisional louver elements in the outside rows farthest away from the center line is set substantially equal to the distance between the louver elements in each row and the length of the divisional louver elements in the inside rows.
摘要翻译：一种热交换器，具有改进的和基本上均匀的热交换效率，设置有多个板状散热片，每个板状散热片具有以交错方式布置的管插入孔，以及插入穿过这些孔的热传递管，多个翅片中的每一个在管之间被双重切割成小的宽度并且升高以形成百叶窗元件，使得百叶窗元件与空气流的流动相交。百叶窗元件的根部定位成围绕管的插入部分，百叶窗元件由形成在管排的中心线的两侧上的中央百叶窗元件组成，并且多个分隔的行形成在中央百叶窗元件的两侧上的百叶窗元件，其中底部留在翅片上的与上述中心线交叉的线上的区域，以及分隔百叶窗元件在距离中心线最远的外侧行中的长度被设置为基本上等于每行中的百叶窗元件之间的距离和内侧行中的分隔百叶窗元件的长度。
