Abstract

The invention discloses a piston type variable-frequency variable-capacity refrigeration compressor comprising a crankcase and a variable-capacity device. An air cylinder and a drainage groove are formed in the crankcase; the variable-capacity device comprises a driving motor, a transmission shaft, an adjusting bolt and a connecting seat; the connecting base is fixed to the crankcase; a containinghole is formed in the connecting base and communicates with the air cylinder through the drainage groove; the adjusting bolt is arranged in the containing hole and is in threaded connection with thecontaining hole; one end of the transmission shaft is coaxially fixed to an output shaft of the driving motor, and the other end of the transmission shaft is in sliding connection with the adjusting bolt; and the driving motor is fixed to the connecting base. According to the piston type variable-frequency variable-capacity refrigeration compressor provided in the invention, the effective stroke volume of the compressor can be adjusted through the variable-capacity device to further adjust the cooling capacity of the compressor.

Description

technical field [0001] The invention relates to the field of piston type frequency conversion refrigeration compressors, in particular to a piston type frequency conversion 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 refrigerator-compressor matching, refrigerators have great differences in compressor cooling capacity requirements 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...
