no. 1 Embodiment

[0026] Hereinafter, referring to the drawings, the use of a carbon dioxide-adapted heat pump water heater will be described as a first embodiment of the present invention. First, the structure will be described. The scroll compressor shown in FIG. 1 is composed of a fixed scroll 2 , a movable scroll 1 , a motor 12 , an airtight container 22 , and a frame 9 . Wherein, the movable scroll 1 is combined with the fixed scroll 2 to form a compression chamber 3 and performs an eccentric rotary motion relative to the fixed scroll 2; the motor 12 drives the movable scroll 1 to perform an eccentric rotary motion; The airtight container 22 accommodates the fixed scroll 2, the movable scroll 1 and the motor 12; the frame 9 is fixed on the wall of the airtight container 22, and the movable scroll 1 is sandwiched in the middle in a rotatable manner. , as a fixed scroll fixing mechanism that supports and fixes the fixed scroll 2; the scroll compressor compresses the working fluid sucked int...

no. 2 Embodiment

[0060] Referring to Fig. 10 below, Figure 11 A second embodiment of the present invention will be described. The difference between this embodiment and the above-mentioned first embodiment is that an oil supply pump 25 driven by the rotating shaft 11 is provided inside the countershaft housing 15; A sealing ring 26 is installed on the surface of the bearing holder 1d, and an oil bag 1g that can travel between the thrust storage chamber 9i and the intermediate pressure chamber 23 is formed on the axial end surface of the bearing holding portion 1d. Since the other configurations are the same, they are given the same symbols and descriptions thereof are omitted here. Components with the same symbols as in the first embodiment are the same components and have the same functions.

[0061] In this embodiment, as shown in FIG. 10 , an oil supply pump 25 driven by the rotary shaft 11 is provided inside the countershaft housing 15 mounted on the sub-bearing support plate 14 of the ...

Abstract

The invention relates to a whorl compressor, with a discharge pressure area. Wherein, the projection As ration as Ad / As between the projection area Ad of the movable whorl disk axial direction of the discharge pressure area at the back of movable whorl disk and the projection area As of the movable whorl disk axial direction is between 0.06-0.16. The inventive whorl compressor can set the movable whorl disk via right force be pressed at the middle pressure of static whorl disk, in variable pressures.

Description

technical field [0001] The invention relates to a scroll compressor, in particular to a scroll compressor which improves compressor efficiency. Background technique [0002] In the scroll compressor, in order to reduce the leakage loss at the front end of the wrap, an intermediate pressure chamber is formed on the back side of the movable scroll, and the movable scroll is pressed against the fixed scroll. If the pressure in the intermediate pressure chamber is too high, the sliding loss at the front end of the coil will increase and the compression efficiency will decrease, so it is necessary to adjust to an appropriate pressure. In Patent Document 1, it is disclosed that as a method of moderately pressing the movable scroll to the fixed scroll, a differential pressure control valve is provided between the intermediate pressure chamber and the suction chamber, and the intermediate pressure is equal to the suction pressure + a certain value. To control, and when the pressure...
