Embodiment 1

[0022] Such as figure 1 , 2 , 3, 4 and 5, a sealed type reciprocating refrigerator compressor cooling set, including the inlet pipe 1 for connecting the air return pipe of the compressor and the outlet pipe 5 for connecting the air return pipe of the refrigerator, The inlet pipe 1 is connected to the air return pipe of the compressor, and the outlet pipe 5 is connected to the air return pipe of the refrigerator. The inlet pipe 1 and the outlet pipe 5 are connected by at least two branch pipes with different flow resistances, and each branch pipe is provided with There is a solenoid valve 6. By adding an external connection kit to the return air pipe of the compressor, when different cooling capacities are required, different flow channels can be opened through the adjustment and control of the solenoid valve 6 on different branch pipes, and different flow channels can be opened. , because the flow resistance of each flow channel is different, the flow rate of the refrigerant ...

Abstract

The invention relates to the field of refrigeration equipment, in particular to a refrigerating capacity changing suite for a sealed reciprocating refrigerator compressor and a using method thereof. A refrigerating capacity changing suite for the sealed reciprocating refrigerator compressor comprises an inlet pipeline used for being connected with an air return pipe of the compressor and an outlet pipeline used for being connected with an air return pipe of a refrigerator, the inlet pipeline and the outlet pipeline are connected through at least two branch pipes with different flow resistances, and each branch pipe is provided with an electromagnetic valve. The refrigerating capacity of the compressor can be adjusted under the condition that the rotating speed of the compressor is not changed, so that the multi-stage change of the refrigerating capacity can be achieved, the cost is low, and the operation is simple.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a cooling set for a sealed reciprocating refrigerator compressor and a method for using the same. Background technique [0002] At present, with the implementation of the national new energy standard, refrigerators and freezers need to conduct energy consumption tests at ambient temperatures of 32°C and 16°C. At lower temperatures, the cooling capacity requirement is lower, and the sample delivery can achieve a better power consumption. Therefore, driven by this demand, the demand for variable speed DC compressors is getting stronger and stronger. [0003] However, the control system of the current variable-speed DC compressor is relatively complicated, which increases the production cost of the product, and is inconvenient to adjust the cooling capacity of the compressor. Contents of the invention [0004] The present invention mainly aims at the above problems, and pr...
