Embodiment Construction
[0033] Such as Figure 1-5 As shown, the present invention provides a scroll compressor with an adjustable internal compression ratio, which includes:
[0034] The stationary scroll 3 and the movable scroll 5 are formed with a first accommodating cavity 30 at the radial center of the stationary scroll 3, and a stationary disc slider 2 is provided in the first accommodating cavity 30. The stationary disc slider 2 also has scroll teeth, and the scroll teeth of the stationary disc slider 2 are engaged with the scroll teeth of the stationary scroll 3 so that the scroll teeth of the stationary disc slider 2 are The spiral extension of the spiral teeth of the fixed scroll 3 in the radial direction;
[0035] A second accommodating cavity 50 is formed in the radial center position of the movable scroll 5, and a movable disk slider 4 is provided in the second accommodating cavity 50, and the movable disk slider 4 also has scroll teeth, so The scroll teeth of the movable disk slider 4 are ...

The invention provides a scroll compressor with the adjustable internal compression ratio, an air-conditioner and a control method. The compressor comprises a static scroll plate and a dynamic scrollplate; a first containing cavity is formed in the radial-direction center of the static scroll plate; a static plate sliding block is disposed in the first containing cavity; a second containing cavity is formed in the radial-direction center of the dynamic scroll plate; a dynamic plate sliding block is disposed in the second containing cavity; and the static plate sliding block and the dynamic plate sliding block can move in the axial direction, and thus a compression cavity defined by the static plate sliding block, the dynamic plate sliding block, the static scroll plate and the dynamic scroll plate can be switched between a two-dimension compression space and a three-dimension compression space. By means of the scroll compressor with the adjustable internal compression ratio, the air-conditioner and the control method, the effect of adjusting the internal compression ratio as required can be effectively achieved, the internal compression ratio can be increased or decreased according to how far the actual working condition deviates from the design working condition, compression losses can be effectively reduced, energy loss caused by too large difference between the internal compression ratio and the external compression ratio under the extreme operating condition is avoided, and the efficiency of the scroll compressor is improved.
Description
Technical field [0001] The invention relates to the technical field of compressors, in particular to a scroll compressor, an air conditioner and a control method with an adjustable internal compression ratio. Background technique [0002] The conventional scroll compressor is a positive displacement compressor with a fixed internal compression ratio (the ratio of the pump body discharge pressure to the suction pressure). The internal compression ratio is only related to the pump body structure parameters and is based on a specific operating condition The compressor’s external compression ratio (the ratio of condensing pressure to evaporating pressure) changes with the operating conditions of the system, and is closely related to parameters such as indoor and outdoor ambient temperature. [0003] When the actual operating conditions deviate from the design conditions, at this time the internal compression ratio and the external compression ratio are inconsistent, the compressor will...
