Embodiment Construction
[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0035] see Figure 1 to Figure 10 According to the variable capacity scroll compressor of the present invention, it includes a fixed scroll 5 and a movable scroll 6 that cooperate with each other, and the movable scroll 6 is provided with a variable volume hole 6a and a leakage passage 6b that communicate with each other; The hole 6a communicates with the compression chamber; the leakage passage 6b communicates with the suction chamber; the leakage passage 6b is provided with a variable volume mechanism 30, which controls the connection between the compression chamber and the suction chamber. The variable volume hole and leakage can reduce or even avoid the overheating phenomenon caused by the refrigerant leakage process when the compressor is runni...

The invention provides a capacity-varying scroll compressor which includes: a compression chamber, a gas suction chamber, and a static scroll plate and a moving scroll plate which are matched to each other. A capacity-varying hole and a leakage channel are disposed on the moving scroll plate and are communicated with each other, wherein the capacity-varying hole is communicated with the compression chamber and the leakage channel is communicated with the gas suction chamber. The leakage channel is provided with a capacity-varying mechanism which controls connection or break-off of the compression chamber and the gas suction chamber. By means of arrangement of the capacity-varying hole and the leakage channel in the moving scroll plate, because the moving scroll plate of the scroll compressor is often in a gas suction environment (namely a low-temperature and low-pressure environment), a phenomenon of overheat due to a leakage process of refrigerant under an partial capacity operation status of the compressor can be reduced and even avoided, so that the compressor is increased in suction volumetric efficiency under the status and further is improved in performances under the status. Meanwhile, axial height increase of the compressor due to the capacity-varying mechanism is avoided, so that the compressor is improved in structural compactness.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a variable capacity scroll compressor. Background technique [0002] The country's high efficiency, energy saving and comfort are the goals that the air conditioning industry is constantly pursuing. The scroll compressor has tended to develop in the direction of larger horsepower and high energy efficiency. The variable capacity scroll compressor can achieve high energy efficiency at low load, and has the characteristics of high reliability and low vibration. It is used in variable flow air conditioning systems more and more widely. [0003] Generally speaking, a scroll compressor is composed of a closed casing, an orbiting scroll, a fixed scroll, a crankshaft, a frame, an anti-rotation mechanism, and a motor. The profiles of the movable and static scrolls are scroll-shaped, and the movable scroll is eccentrically installed relative to the fixed scroll with a difference of 180 degree...
