摘要： A refrigeration cycle has a compressor, an outdoor rotary-type heat exchanger, a motor-operated expansion valve, and an indoor rotary-type heat exchanger which are sequentially connected to each other to circulate a refrigerant. A tank is set in a connected state or a non-connected state with respect to a refrigerant discharge side of the compressor. A detector detects at least a pressure at one side of each of the exchangers. A first controller sets the tank in a non-connected state when a normal operation of an air conditioner is to be started, and controls the capacity of the compressor, the rotational speed of the exchangers, and the opening degree of the valve in accordance with an air-conditioning load, thereby performing the normal operation of the air conditioner. A second controller causes the compressor to keep operating at a predetermined capacity until a detection pressure from the detector coincides with a preset value, when the air conditioner is to be stopped, and sets the tank in a connected state while controlling the valve to a predetermined opening degree, thereby recovering a refrigerant in the tank. A third controller rotates the exchangers at a predetermined speed when the air conditioner is to be started, and sets the tank in a connected state while controlling the valve to a predetermined opening degree, thereby filling the refrigerant in the exchangers from the tank.

摘要翻译： 制冷循环具有彼此依次连接以使制冷剂循环的压缩机，室外旋转式热交换器，电动膨胀阀和室内旋转式热交换器。 相对于压缩机的制冷剂排出侧，将罐设定在连接状态或非连接状态。 检测器检测每个交换器的一侧的至少一个压力。 当空调的正常运行开始时，第一控制器将油箱设定在非连接状态，并根据控制器控制压缩机的容量，交换器的旋转速度和阀的开度 空调负荷，从而进行空调机的正常运转。 第二控制器使得压缩机保持在预定容量下运行，直到来自检测器的检测压力与预定值一致，当空调器停止时，并且将罐设定在连接状态，同时将阀控制到预定的 开度，从而回收罐中的制冷剂。 第三控制器在要启动空调器时以预定速度旋转交换器，并且在将阀控制到预定开度的同时将罐设置在连接状态，从而从罐中填充交换器中的制冷剂。

摘要： A cooling fin, used in a heat-exchanger, which includes a breakable line section extending from one side of the cooling fin plate to a substantially middle portion of the plate in a direction perpendicular to the elongated direction of the plate and a substantially V-shaped notch formed at a portion of the other side of the plate corresponding to the extended end of the breakable line section. The cooling fins are stacked in prescribed numbers to make a cooling fin block. The breakable line section includes a perforated line and is broken when one part of the cooling fin block in the elongated direction is bent against the other part of the block along the breakable line section.
