Problems solved by technology

[0004] However, during the process from entering the compressor to entering the cylinder 14, the refrigerant is mixed with the high-temperature refrigerant in the compressor and the temperature rises. In addition, because the refrigerant takes too long from entering the compressor to entering the cylinder 14, it is compressed during the process. The high-temperature refrigerant in the machine is heated, causing the temperature of the refrigerant discharged from the compressor to rise, the amount of refrigerant to decrease, and the efficiency of the compressor to decrease.

Embodiment Construction

[0035] According to the intake structure of the reciprocating compressor disclosed in the present invention, firstly, according to the theoretical compression work of piston compression, please refer to figure 2 As shown, the compression work required for one compression of the piston is roughly the same no matter whether the temperature of the sucked refrigerant is higher or lower. In a reciprocating compressor, the low-temperature and low-pressure refrigerant gas entering the cylinder becomes high-temperature and high-pressure refrigerant gas after being compressed by the piston. The compression work required for one piston compression is the area of ​​the cross-sectional area S in the figure. The state of the refrigerant gas during the piston compression movement:

Abstract

An air inlet structure for the reciprocating compressor in order to decrease the power needed by compression and the load of condenser features that the low-temp and -pressure cold medium gas coming from evaporator can flow through low-pressure cold medium inlet tube, is then directly and quickly sucked into a compressing cylinder, and finally is compressed. It is not mixed with the high-temp cold medium gas in compressor.

Description

technical field [0001] The invention relates to an air intake structure applied to a reciprocating compressor, in particular to an air intake structure of a reciprocating compressor capable of directly and quickly sucking low-pressure refrigerant into a compression cylinder. Background technique [0002] General refrigerator compressors, see figure 1 After the low-pressure and low-temperature refrigerant gas enters through the suction port 11 on the shell 10, it first goes to the intake volume chamber 12, then enters the suction passage of the valve seat 13 through the intake volume chamber 12, and finally enters the interior of the cylinder 14 through the suction passage to carry out The compression process of the piston 15. Through the piston movement in the compressor, the low-pressure and low-temperature refrigerant gas is compressed into high-pressure and high-temperature refrigerant gas. At this time, the exhaust valve is opened to discharge the high-pressure and high...
