摘要： PROBLEM TO BE SOLVED: To provide a refrigerant distributor securing safety by lessening an influence which a set angle gives on distribution characteristics even in case that individual difference occurs in an attaching angle by production tolerance, etc., when a heat exchanger is equipped with the refrigerant distributor.
SOLUTION: An inflow pipe 10 of the refrigerant distributor 80 is constituted so as to have an internal groove 13. Surface tension by action of the groove shape makes more dominant than gravity which refrigerant 141 inside the groove 13 receives. To be more precise, the groove part with a minimum internal diameter Dmin and a maximum groove width Wmax which are the most suitable for the set angle θ is constituted. Also, the refrigerant distributor is constituted in such a manner that an elbow angle of the inflow pipe is made over 60° larger than a ground structural part installed in an internal face.

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

摘要： PROBLEM TO BE SOLVED: To facilitate removing an air conditioner body from an installing board without deteriorating the essential performance of the air conditioner at an operation mode. SOLUTION: A joint of a decorative cover 3 with a discharge cover 4 is unlocked to release the cover 4, thereby opening a cabinet hole 2b provided in a cabinet 2 downside. A screw-driver 18 is inserted into the opened hole 2b inwards near a lock claw 2a provided at a lower part of the cabinet backside and moved to deform the lower part down, causing the lock claw 2a to move down until the claw 2a is put out through a hole 6a provided in the lower side of an installing board 6. A joint of the board 6 with the cabinet 2 is unlocked to remove an air conditioner 1. The cabinet hole 2b locates inside the cover 4 to avoid resisting against discharged air during operating, resulting in no deterioration of the performance at the operation mode. Only opening the discharge cover 4 suffices for easily conducting the removing work, without removing other separate components from the air conditioner 1.

摘要： PROBLEM TO BE SOLVED: To reduce indoor air humidity by prescribed quantity by simple operation, and automatically return an air conditioner to a dehumidifying operation state for an initial set humidity.
SOLUTION: Before time t=0, operation is performed in a normal dehumidifying operation mode for set humidity of 50% and compressor rotation of 3000 rpm. As a powerful button is operated by an operation remote control, the set humidity is changed into 40%, and powerful dehumidifying operation is performed to continuously rotate a compressor at 3600 rpm to achieve the set humidity. Indoor air humidity is thus quickly reduced to the set humidity. The powerful dehumidifying operation is canceled after prescribed period T
1 to return the set humidity to 50%. The compressor is continuously rotated at 3000 rpm for a prescribed period T
2 , and then, as the indoor air humidity becomes almost 50%, normal dehumidifying operation is restored (T
