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...

Abstract

The invention provides a scroll compressor with variable capacity. According to the variable capacity scroll compressor of the present invention, it includes a compression chamber, a suction chamber, and a fixed scroll and a movable scroll that cooperate with each other, and the movable scroll is provided with a variable volume hole and a leakage channel that communicate with each other; The variable volume hole is connected with the compression chamber; the leakage passage is connected with the suction chamber; the leakage passage is provided with a variable volume mechanism, and the variable volume mechanism controls the on-off of the compression chamber and the suction chamber. The variable volume hole and the leakage channel are set on the movable scroll, because the scroll compressor's movable scroll is usually in the suction environment (that is, a low-temperature and low-pressure environment), so it can reduce or even avoid the loss of refrigerant when the compressor is running at a partial capacity. The overheating phenomenon caused by the leakage process can improve the suction volume efficiency of the compressor in this state, thereby improving the performance of the compressor in this state, and can also avoid the increase in the axial height of the compressor caused by the variable capacity mechanism. Improve the compactness of the compressor structure.

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...
