を該吐出ポートから吐出するようになっている。A rotary compressor, which is often used in air conditioners, includes a cylinder, a rotor that rotates eccentrically within the cylinder, and vanes that are always urged toward the rotor and slide against the rotor.
It includes a suction port for introducing refrigerant to be compressed into a compression chamber formed by a cylinder and a rotor, a discharge port for discharging the refrigerant compressed in the compression chamber, and a discharge valve attached to this discharge port. The refrigerant sucked through the suction port is compressed during approximately one rotation of the rotor, and the compressed refrigerant is discharged from the discharge port.
ところで、従来では暖房運転立ち上がり時に。 By the way, conventionally, when heating operation starts up.
停止時における圧縮機内部への冷媒の寝込みと圧縮機の
熱容量のため、冷媒回路が初期ガス欠状態となり圧縮機
の圧縮仕事が減少し、それに伴いモータ入力が減少する
ため、冷凍サイクルが正常に戻るまで時間がかかってい
た。Due to the refrigerant stagnation inside the compressor and the heat capacity of the compressor when the compressor is stopped, the refrigerant circuit becomes initially starved of gas, and the compression work of the compressor decreases.As a result, the motor input decreases, which prevents the refrigeration cycle from operating normally. It took a while to get back.
この発明は、このような技術的背景に鑑みてなされたも
ので、その目的は、冷凍サイクルの立上り時間をより短
くし得るようにした回転式圧縮機を提供することにある
。This invention was made in view of such a technical background, and its purpose is to provide a rotary compressor that can shorten the start-up time of a refrigeration cycle.

いる。A vane that slides on the surface of this roller, a suction port that introduces the gas to be compressed into the inner chamber formed between the cylinder and the roller, and a discharge valve are attached to discharge the compressed gas in the inner chamber. A rotary compressor having a discharge port is provided with discharge resistance control chamber means for changing the discharge resistance of the discharge port in accordance with a preset temperature of the discharge port.
上記手段によれば、圧縮機が冷えている間は吐出ポート

うに変化する。これにより、立ち上がり時の圧縮仕事を
増し、モータ入力を増して吐出ガスの比エンタルピを上
げ、圧縮機を短時間で高温にすることができる。According to the above means, the discharge resistance of the discharge port is large while the compressor is cold, and changes to become small as the compressor warms up. This increases the compression work at startup, increases the motor input, and increases the specific enthalpy of the discharged gas, making it possible to heat the compressor to a high temperature in a short time.

を解消することができる。In this embodiment, the patent plate 22 is made of a shape memory alloy. When the refrigerant is cold, the valve holder 22 expands and the discharge valve 22 extends as shown by the dashed line in FIG.
The amount of refrigerant discharged from the discharge valve 21 is reduced by regulating the opening degree of the discharge valve 21. Then, when the temperature reaches a preset temperature, the shape memory alloy deforms into a preset shape according to this temperature, thereby realizing a predetermined valve opening degree. Thereby, the refrigerant in the compression chamber 19 is overcompressed, the compression work at startup and the motor input are increased, the specific enthalpy of the discharged gas refrigerant is increased, and the compressor 11 can be brought to a high temperature quickly. Furthermore, the increase in the specific enthalpy of the discharged gas suppresses the liquefaction phenomenon of the refrigerant within the case, and it is possible to eliminate the phenomenon of dilution of refrigerating machine oil due to miscondensation within the case, that is, the insufficient formation of oil films between each component.

An opening adjustment plate 23 made of a shape memory alloy may be provided between the valve 21 and the valve holder 22 so that the valve opening can be changed in accordance with the temperature of the refrigerant.

転に復帰させることができる。Since the specified valve opening cannot be obtained unless the temperature of the discharge port rises to at least a preset temperature, the compressor is shortened by increasing the compression work and motor input at startup to increase the specific enthalpy of the discharged gas. Normal operation can be restored within a short time.
