The working principle of the valve group assembly is as follows: when air suction is performed, the first air suction valve 121, the second air suction valve 122 and the third air suction valve 123 are opened, and the refrigerant enters the compressor through the first air suction port 211, the second air suction port 212 and the third air suction port 213; when the air is discharged, the first air suction valve 121, the second air suction valve 122 and the third air suction valve 123 are closed, and the refrigerant is discharged from the compressor through the second discharge port 23 and the first discharge port 111.
As shown in fig. 4a, comparing the valve set of three suction valves (long arm) in this embodiment with the valve set of a conventional single suction valve, it is found that: with the gradual increase of the running frequency of the compressor, the three suction valves (long arms) and the conventional single suction valve show that the volumetric efficiency of the compressor is increased firstly and then reduced, and when the running frequency is the medium frequency and the high frequency, the volumetric efficiency of the compressor of the three suction valves (long arms) is greater than that of the conventional single suction valve. As shown in fig. 4b, the valve set of three suction valves (long arm) and the valve set of three suction valves (normal) in the present embodiment are compared with the conventional valve set of single suction valve experimentally, and it is found that: along with the gradual increase of the running frequency of the compressor, the volumetric efficiency of the compressor is increased firstly and then reduced by the three suction valves (long arms), the volumetric efficiency of the compressor is higher than that of the three suction valves (long arms) and the volumetric efficiency of the compressor is higher than that of the conventional single suction valve when the running frequency is medium frequency and high frequency.
The main reasons for the above experimental results are that the air suction valve plate 1 has a fast response speed and a high air suction efficiency, and the necking structure 125 of the air suction valve 12 has a longer length and a narrower width, so that a sufficient effective flow area can be ensured for high frequency, and further, the high frequency cooling capacity is improved; in addition, by using the valve group assembly in the embodiment, the diameter of a single air suction port is reduced, the stress of the air suction valve 12 is small, the service life is prolonged, the pneumatic noise of the operation of the compressor is reduced, the fixed displacement compressor can operate in a wider operation frequency range (16-150 Hz), the low-frequency performance of the compressor is ensured, a larger displacement refrigerating capacity can be achieved when the compressor operates at a high frequency, and the power density of the compressor is improved; meanwhile, the refrigerating capacity of the compressor at low evaporation temperature (such as minus 35 ℃ to minus 50 ℃) is improved, and the deep freezing function of the refrigerator is realized.
