Abstract

The invention discloses a piston-type variable frequency variable capacity refrigeration compressor, which comprises a crankcase and a variable capacity device. The crankcase is provided with a cylinder and a drainage groove; The seat is fixed with the crankcase, and there is a receiving hole in the connecting seat, the receiving hole communicates with the cylinder through the drainage groove, the adjusting bolt is set in the receiving hole, and the adjusting bolt is screwed to the receiving hole, and one end of the transmission shaft is the same as the output shaft of the driving motor. The shaft is fixed, the other end of the transmission shaft is slidingly connected with the adjusting bolt, and the driving motor is fixed with the connecting seat. The invention provides a piston-type variable-frequency variable-capacity refrigeration compressor, which can further adjust the cooling capacity of the compressor by adjusting the effective stroke volume of the compressor through a variable-capacity device.

Description

technical field [0001] The invention relates to the field of piston type variable frequency refrigeration compressors, in particular to a piston type variable frequency variable capacity refrigeration compressor. Background technique [0002] With the development of the national economy, people's living standards have gradually improved. People have higher and higher requirements for energy saving, moisturizing and fresh-keeping of refrigerators and freezers. As the core component of refrigerators and freezers, compressors are the key to improving the quality of refrigerators. According to the characteristics of the refrigerator-compressor matching, the refrigeration capacity of the refrigerator varies greatly under different ambient temperatures. For example, in the refrigerator power consumption test, the heat load of the refrigerator under the 16° ambient temperature test condition is generally only about 50% of the refrigerator heat load under the 32° ambient temperatu...
