Strangle in Mil's refrigerating plant in the dimension of the present invention, cold displacer 2 and hot displacer 11 are divided into the total measurement (volume) of cylinder
Three parts：Hot chamber 12, cold chamber 1 and room temperature chamber A4-1, room temperature chamber B4-2.Two displacers are with certain phase contrast（90 ° of left sides
It is right）Move back and forth, order about gas in the jar and circulated in three working chambers by hot and cold regenerator.Pressure in refrigerating plant becomes
Change is based on hot cylinder, because the total measurement (volume) of whole system and total work mass conservation, the gas work in system
The pressure of matter and its mean temperature are directly proportional.When hot displacer 11 is in its bottom dead center-nearby, the volume of hot chamber 12 is larger, its
In gas working medium it is more, now the mean temperature of gas working medium is just higher in system, and therewith pressure is also just larger.Conversely,
At hot displacer 11 during dead point thereon, the volume of hot chamber 12 goes to zero, and now the mean temperature of gas working medium is relatively low in system,
Pressure is less.When dimension strangles Mil's refrigerating plant steady running, its detailed course of work is as follows：
First, the fishing boat engines tail gas of high temperature enters heat recovery heat exchanger 14 from gas inlet 15, in waste heat recovery heat exchange
Gas working medium on the outside of the pipe of device 14 in heating tube, transfers heat to gas working medium, and gas working medium is heated in hot chamber 12,
Drive hot displacer 11 to by top dead-centre mutually its bottom dead centre movement from the different gas-powered power for producing of the temperature difference, the volume of hot chamber 12 increases
Greatly, now cold displacer 2 is moved to top dead-centre, pushes the gas working medium in cold chamber 1 to room temperature chamber A4-1, room temperature chamber B4-2, this
During gas working medium when flowing through cold regenerator 21, wherein gas working medium in close two room temperatures chamber is heated to by regeneration filler
Temperature, subsequently into room temperature chamber A4-1, room temperature chamber B4-2.Hot displacer 11 to bottom dead centre during moving by room temperature chamber
Gas working medium in A4-1, room temperature chamber B4-2 pushes hot chamber 12 to, when gas working medium passes through hot regenerator 16 during this, by wherein
Regeneration filler heating, the pressure and temperature in system rises rapidly in this process, and heat then passes through water-filled radiator 18
Take away.Sea water enters water-filled radiator by water-filled radiator entrance 17, the heat of the gas working medium in absorption tube, and then Jing connects
Pipe 19 takes away heat from water-filled radiator outlet 20.This process dynamic coil linear motor 8 is started working, and its operating frequency is close to
The frequency of vibration of the vibrational system produced by hot and cold displacer, makes system keep good operating mode.
Then hot displacer 11 continues to be moved to bottom dead centre in the presence of driving force, make pressure and temperature in system after
Continuous to rise, in the process, cold displacer 2 starts by the downward dead point movement of its top dead-centre, in room temperature chamber A4-1, room temperature chamber B4-2
Portion gas working medium be pushed in cold chamber 1, it is cold by the regeneration filler in cold regenerator 21 when through cold regenerator 21
But, subsequently in cold chamber 1.Pressure in this procedures system has declined.
Then cold displacer 2 continues to its bottom dead centre movement, and the volume for causing cold chamber 1 continues to increase, and hot displacer 9 is then
Moved from its bottom dead centre to top dead-centre direction, the volume reducing in hot chamber 12.During hot displacer 11 is moved to top dead-centre,
The gas working medium of the high temperature in hot chamber 12 enters room temperature chamber A4-1, room temperature chamber B4-2 by hot regenerator 16.Meanwhile, in cold discharge
During device 2 continues to be moved to bottom dead centre, the gas working medium in part room temperature chamber A4-1, room temperature chamber B4-2 is pushed to cold chamber
In 1, gas working medium is cooled down when cold regenerator 21 is flowed through by regeneration filler therein during this, subsequently in cold chamber 1.
Afterwards hot displacer 9 continues up dead point movement, and cold displacer 2 then starts from its bottom dead centre to its top dead-centre movement, at this moment cold
The volume in chamber 1 and hot chamber 12 reduces simultaneously.Gas working medium in hot chamber 12 is cold by regeneration filler wherein by hot regenerator 16
But, temperature is reduced to the temperature in close room temperature chamber, and the pressure of system also declines therewith.Portion gas working medium in cold chamber 1 first exists
The heat of refrigerating medium is absorbed in cool end heat exchanger 23, then close room is heated to by regeneration filler therein through cold regenerator 21
The temperature of warm chamber A4-1, room temperature chamber B4-2, subsequently into room temperature chamber.In the process, the pressure of internal system gas has been also
Reduce, and in this process, gas working medium absorbs heat in cool end heat exchanger 23, produces cold, and cold is by refrigerating medium（Glacial epoch is cold
Matchmaker）Pass it under the promotion of solution circulation pump 24 in fishing boat refrigerating chamber 26, cold is exported by heat exchanger 25, be used for
Refrigeration or the purpose of ice making.
