    • PROBLEM TO BE SOLVED: To provide a connecting structure of a check valve capable of preventing reverse connection of the check valve when the check valve is connected to a capillary tube in which a refrigerant is circulated.
      SOLUTION: Connecting portions 16a, 16b, 16c, 16d, 16e, 16f of uniform diameter are formed at both end sides of the check valve 2B allowing the refrigerant to flow only in one direction. The indoor-side connecting portions 16d, 16e, 16f are provided with stoppers 20. The stoppers 20 control an insertion length at an indoor side to a length C. Beads 18 (projections) indicating inserting portions 19a of the length A are formed on an outdoor-side end portion of the capillary tube 3 for heating and end portions of outdoor-side capillary tubes 9, 10. The length A of the inserting portion 19a is determined to be longer than the length C controlled by the stopper 20. The inserting portions 19a are inserted into the indoor-side inserting portions 16d, 16e, 16f. Thus the reverse connection of the check valve 2B can be found at first glance.

    • PROBLEM TO BE SOLVED: To start, at the time of cooling dehumidifying operation, the cooling dehumidifying operation after performing cooling operation for a predetermined time only when the compressed state of a refrigerant in an outdoor heat exchanger is poor (the compression is not better).
      SOLUTION: In an air conditioner in which an expansion valve having a pressure reducing function varied depending on the direction of carrying the refrigerant is interposed between two divided indoor heat exchangers to perform cooling dehumidifying operation or heating dehumidifying operation by use of the expansion valve, the compressed state of the refrigerant in the outdoor heat exchanger is determined, at the time of the cooling dehumidifying operation, in reference to the previous operation mode, the stopping time of a compressor, and the temperature of the outdoor heat exchanger (steps ST2-ST4). On the basis of this, it is determined whether the cooling dehumidifying operation is started without cooling operation or after performing the cooling operation for a determined time.

    • 要解决的问题:首先,在冷却除湿运转时,只有在室外热交换器中的制冷剂的压缩状态差的情况下,进行制冷运转规定时间后的冷却除湿运转(压缩为 不好) 解决方案:在具有减压功能的膨胀阀根据承载制冷剂的方向而变化的空调器被插入在两个分开的室内热交换器之间,以通过使用膨胀进行冷却除湿操作或加热除湿操作 在室外热交换器中的制冷剂的压缩状态,在冷却除湿运转时,参照先前的动作模式,压缩机的停止时间和室外热交换器的温度(步骤 ST2-ST4)。 在此基础上,确定冷却除湿操作是否在没有制冷操作或在执行制冷操作一段确定的时间之后开始。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide an expansion valve for controlling supercooling degree, which enables a reduction of fixing space and fixing processes by incorporating the function of a check valve.
      SOLUTION: A valve seat 10 is formed midway between refrigerant paths 4 and 6, and a valve body 12 for full-opening and full-closing operation is arranged so as to face the valve seat 10 from the refrigerant path 4. The valve body 12 is disposed at the side of the refrigerant path 4 and is provided with; a differential pressure valve consisting of a housing 26 having a valve seat 38 and a valve body 22; and a through-hole 18 and a slit 16, which constitute an integration, to serve as a throttling channel. In a cooling operation, the refrigerant that has been introduced to the refrigerant path 4 allows the valve body 12 to seat on the valve seat 10 and close the channel, and thereafter flows to the refrigerant path 6 through the differential pressure valve and the through- hole 18, being throttled and expanded by the slit 16. In a heating operation, the refrigerant that has been introduced to the refrigerant path 6 presses and fully opens the valve body 12 and continues to flow to the refrigerant path 4.

    • 要解决的问题:提供一种用于控制过冷度的膨胀阀,其通过结合止回阀的功能而能够减少定影空间和定影过程。 解决方案:阀座10形成在制冷剂路径4和6之间的中途,并且用于全开和全关闭操作的阀体12被布置成从制冷剂路径4面对阀座10.阀体12 设置在制冷剂路径4的侧面,并且设置有: 差压阀由具有阀座38和阀体22的壳体26组成; 以及构成一体化的通孔18和狭缝16,用作节流通道。 在冷却运转中,已经被导入到制冷剂路径4的制冷剂允许阀体12位于阀座10上并关闭通道,然后通过差压阀流过制冷剂路径6, 孔18被狭缝16节流和膨胀。在加热操作中,已经被引入制冷剂路径6的制冷剂按压并完全打开阀体12并继续流到制冷剂路径4。
