External environment.Subsequent gas enters vascular 304 with laminar flow, and the gas in pipe is squeezed to hot end, and temperature increases, hot end heat exchange
Device 305 takes away heat, and the temperature and pressure of gas is in a slight decrease in vascular 304, when the pressure in 201 exit of Linearkompressor
When for minimum pressure, gas expansion in vascular 304 and obtain low temperature, cooling capacity is exported by cool end heat exchanger 303.It is changed with hot end
What hot device 305 was connected is function recoverer 30, still has certain acting ability by the gas of hot end heat exchanger 305, into function
104 expansion work of piston is recycled to function after the compression chamber 101 of recoverer 30, the gas in function reclaiming chamber 102 passes through after being compressed
Function recovery tube 503 or function recovery tube 504 enter the right compression conduit 502 of compressor, play the effect of auxiliary compression.
As shown in Fig. 2, when cooling load reduces, it is only necessary to, can will be electric when linear type vascular refrigerator (left side) working medium
Magnet valve 403 and solenoid valve 404 simultaneously close off, and the path of sound function circulation is as shown in Figure 2 at this time.Gas working medium only can be in a vascular
Circulation in refrigeration machine and function recovery system is working although only having a vascular refrigerator at this time, and the two of function recoverer 30
A function reclaiming chamber 102 in recycling sound function, the sound function of recycling respectively by corresponding two function recovery tubes 503 and function recovery tube 504 into
Enter right compression conduit 502, plays the effect of auxiliary compression.
Equally, it is only necessary to, can be same by solenoid valve 401 and solenoid valve 402 when linear type vascular refrigerator (right side) working medium
When close, at this time sound function circulation path as shown in figure 3, two function reclaiming chambers 102 in recycling sound function.
It is worth noting that, in order to avoid gas in whole system sinuous flow, it is necessary to assure it is some once:
1, solenoid valve 401, solenoid valve 402 are necessary for same and open same close.Solenoid valve 403 and solenoid valve 404 are necessary for same with opening
It closes.The opening/closing time needs of solenoid valve mutually stagger, and another two solenoid valve is to close in the open state at two solenoid valves
State, that is to say, that remain that Linearkompressor driving separate unit sterlin refrigerator works, guarantee at Linearkompressor
Reach best match in best operating point, and with sterlin refrigerator.
2, solenoid valve 401 and solenoid valve 403 must be placed in right compression conduit 502, and must be located at junction A with
After grade between heat exchanger, the phenomenon that otherwise will appear gas turbulence.
Two vascular refrigerators of the invention share a set of function recoverer 30, keep machine system simpler compact, and
The empty volume of whole system is effectively reduced, the promotion of refrigeration performance is conducive to.
Further, either two vascular refrigerators work at the same time still wherein one work, the two of function recoverer 30
A function reclaiming chamber 102 is in recycling sound function, so that function recovery efficiency is higher.
The action and effect of embodiment
The one drag two function reclaiming type vascular refrigerator according to involved in the present embodiment, because compressor uses compression piston pair
Set arrangement, it is ensured that axial force can obtain maximum balance, be greatly reduced vibration, enhance reliability.
Further, function recovery system is increased, two function recycling piston of function recovery system is equally symmetrical with compressor
