Abstract

The invention provides a cylinder seat, a compressor and a refrigerator. The cylinder seat comprises at least two crankshaft holes and cylinders, wherein the at least two crankshaft holes are used forinstalling crankshaft parts, and the crankshaft parts in different crankshaft holes can rotate independently; and the number of the cylinders is equal to that of the crankshaft holes, the positions of the cylinders are in one-to-one correspondence with the crankshaft holes, and the crankshaft parts in the different crankshaft holes can drive pistons in the corresponding cylinders to move when rotating independently, so that the cylinders conduct independent compression. According to the cylinder seat, at least two independent crankshaft holes and cylinders are designed, and then multiple motors can be used for simultaneous and alternative driving, and independent control of multiple cylinders is achieved; and the compressor adopting the cylinder seat can achieve working modes of being single-cylinder single-stage, multi-cylinder single-stage and multi-cylinder multistage, so that a refrigerating system has a multistage independent temperature control function. In the multi-cylinder multistage working mode, the refrigerating system can achieve deep freezing at the temperature below minus 33 DEG C, and the energy efficiency of the refrigerating system is higher.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a cylinder block, a compressor and a refrigerator system. Background technique [0002] With the continuous improvement of living standards and quality, refrigerator products have generated application requirements such as independent temperature control, deep freezing below minus 33°C, and high efficiency. For the requirement of independent temperature control, the refrigeration system of the refrigerator is required to have the ability to provide multiple evaporation pressures, and the compressor is required to have multiple compression performances. [0003] The existing double-cylinder compressors cannot realize the independent control of the two cylinders. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is that the existing two-cylinder compressor cannot realize the independent control of the two ...
