And in actual control process, after top dead center can be automatically found by the controller of linear compressor, to upper dead
The position of point is compared with stroke or power, and the volume of cylinder is adjusted using the parameter of stroke or power, specific as follows：
Control and regulation method based on stroke includes：When the linear compressor is in top dead-centre state, piston is judged
Current stroke X and piston benchmark stroke X0 size；If X ＜ X0, by opening the first valve and the second valve, shell
Interior refrigerant enters to reduce the vacuum in vacuum reservoir body in vacuum cylinder body, and motion stops promote piston to cylinder by stator
Exhaust valve plate direction movement；If during X ＞ X0, by closing the first valve and opening the second valve, pass through linear compressor
Suction and discharge effect the refrigerant in shell is completely exhausted out outside shell, to improve the vacuum in vacuum reservoir body, then, then close
The second valve is closed, and opens the first valve, motion stops are pullled piston by stator and moved to the exhaust valve plate direction away from cylinder.
Specifically, stroke can be divided into several shelves, gear >=2, i.e. X1, X2 ... ... Xn-1, Xn, benchmark stroke X0, so as to adjust
The Push And Release of one valve 51 and the second valve 93, when reaching top dead-centre, judge, as Xn ＜ X0, to illustrate clearance be present, vacuum chamber
Interior vacuum should decline, and by opening the second valve, part of refrigerant enters vacuum cylinder body, so as to improve vacuum reservoir
The pressure of body, piston is promoted to be moved to the direction of exhaust valve plate 18 of cylinder；Conversely, as Xn ＞ X0, illustrate to exceed clearance, collide
Exhaust valve plate phenomenon occurs, and the vacuum in vacuum reservoir body should improve, and by closing the first valve, does not allow refrigerant to flow back to outer
In shell, the second valve is opened, by the suction and discharge effect of compressor, shell inner refrigerant is completely exhausted out outside shell, so as to true
Vacuum in empty cylinder body can also be improved, and now turn off the second valve, and the vacuum in vacuum reservoir body is kept, then opens first
Valve, negative pressure produces in vacuum reservoir body, pulls piston and is moved to the exhaust valve plate direction away from cylinder.
Control and regulation method based on power includes：When the linear compressor is in top dead-centre state, straight line is judged
The current power P of compressor and the reference power P0 of linear compressor size；If P ＜ P0, by open the first valve and
Second valve, the refrigerant in shell enter in vacuum cylinder body to reduce the vacuum in vacuum reservoir body, and motion stops pass through stator
Piston is promoted to be moved to the exhaust valve plate direction of cylinder；If during P ＞ P0, by closing the first valve and opening the second valve,
The refrigerant in shell is completely exhausted out outside shell by the suction and discharge effect of linear compressor, it is true in vacuum reservoir body to improve
Reciprocal of duty cycle, then, the second valve is turned off, and open the first valve, motion stops pull piston to the row away from cylinder by stator
Move in air valve plate direction.Specifically, power can be divided into several shelves, gear >=2, i.e. P1, P2 ... ... Pn-1, Pn, benchmark work(
Rate P0, detailed process refer to the control method of above-mentioned stroke, will not be repeated here.
