摘要： PROBLEM TO BE SOLVED: To reduce power consumption while reducing refrigerant flowing sound and ensuring a necessary dehumidification quantity in dehumidifying operation for performing dehumidification while preventing drop of room temperature by a refrigerating cycle. SOLUTION: In a dehumidification throttle device to be used in dehumidifying operation, which is disposed between two pieces of a halved use-side heat exchanger, when a valve rod 15 contacts a valve seat 20 to close a valve port 21, a refrigerant throttle passage 28 is formed by a cutout groove 19 provided in the valve seat 20 and the valve rod 15, and valve chambers 23 and 24 are mutually connected by the refrigerant throttle passage 28. Even if the passage 28 is clogged by dust or the like, the dust can be removed by raising the valve rod 15. Therefore, the passage 28 can be narrowed to increase the refrigerant throttle quantity, whereby the evaporation temperature can be reduced. Consequently, since the necessary refrigerant circulation quantity can be minimized while ensuring a necessary dehumidifying quantity, the refrigerant flowing sound can be reduced, as well as the kinetic energy of the refrigerant flow. Further, the minimization of the refrigerant circulation quantity leads to reduction in rotating speed of a compressor and thus reduction in power consumption. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：减少制冷剂流动声音的功率消耗，并且在除湿制冷循环中防止室温下降的同时，在除湿操作中确保必要的除湿量进行除湿。解决方案：在设置在两片半利用侧热交换器之间的用于除湿运转的除湿节流装置中，当阀杆15与阀座20接触以关闭阀口21时，制冷剂节流通道28由设置在阀座20和阀杆15中的切口槽19形成，阀室23和24由制冷剂节流通道28相互连接。即使通道28被灰尘或可以通过升高阀杆15来除去灰尘。因此，可以使通道28变窄以增加制冷剂节流量，由此可以降低蒸发温度。因此，由于在确保必要的除湿量的同时可以使必要的制冷剂循环量最小化，所以可以降低制冷剂流动声音以及制冷剂流动的动能。此外，制冷剂循环量的最小化导致压缩机的转速降低，从而降低功率消耗。版权所有（C）2007，JPO＆INPIT
