Refrigerant II enters evaporator II111 evaporation endothermics after throttling arrangement III110 throttles, then by regenerator III112
Heat up, and the cold temperature of two-stage system is formed at the evaporator II111.The refrigerant gas formed after being evaporated through evaporator III114
The refrigerant gas that body is formed after being heated up through regenerator III112 mix at Rendezvous Point I1, and mixed refrigerant gas are again
With only through throttling arrangement II108 throttling the liquid phase refrigerant without evaporator evaporation mix at Rendezvous Point II2, mixed gas
Liquid mix refrigerant is flowed through after regenerator II107 continues to heat up and collected with the refrigerant gas after being evaporated through evaporator I106 again
Mix at point III3, the gas-liquid mixed refrigerant through being repeatedly mixed to form is eventually passed after regenerator I103 heats up and returns to the pressure
Contracting machine 101 carries out the compression of kind of refrigeration cycle next time.
In the present embodiment, the liquid phase refrigerant formed after being separated through the gas-liquid separator I104 is divided into two branch roads again,
The realization of the patency and integrally cooling temperature of backflow refrigerant is mainly considered, throttling arrangement II108 and correspondence is increased
Pipeline, after increase, evaporator can be controlled by adjusting the restriction effect and amount of restriction of the throttling arrangement II108
The refrigerating capacity of I106 and the flow of refrigerant in the loop of compressor 101 is returned to.Such as the unit that dashed rectangle in Fig. 1 is chosen
It is shown, the gas-liquid separator I104, regenerator II107, throttling arrangement I105, throttling arrangement II108, evaporator I106 composition
One refrigeration module, the refrigeration module is at least 1, is connected between each refrigeration module.The refrigeration module can be according to reality
Infinite copy is carried out the need for the engineering of border, if being actually needed multiple different cryogenic temperatures, it is possible to increase refrigeration module, come
Realize multiple different cryogenic temperatures.
In the present embodiment, described one-level cryogenic temperature, the cold temperature of two-stage system and one-level refrigeration temperature in three-level cryogenic temperature
Degree is cryogenic temperature higher, and the cold temperature of two-stage system is relatively low cryogenic temperature, and three-level cryogenic temperature is minimum cryogenic temperature.
