The specific embodiment
In the embodiment shown in fig. 1, the circulatory system of one three temperature refrigerator is made up of compressor 1, condenser 2, main capillary 3, magnetic valve 4,5, the first evaporimeters 6, the second evaporimeters 7, the 3rd evaporimeter 8 and secondary capillary 9.During operation, compressed cold-producing medium is behind compressor outlet process condenser condenses, main capillary-compensated, enter first evaporimeter by two magnetic valve A, B simultaneously or by turns and second evaporimeter freezes, enter the 3rd evaporimeter by these two evaporator outlets again and make it abundant gasification.After current two evaporimeters successively reach design temperature, magnetic valve A, B successively close, cold-producing medium is through the throttling once more of secondary capillary, enter the 3rd evaporimeter then and freeze, treat that of living in chamber of the 3rd evaporimeter reaches design temperature after, compressor cuts out, finish a kind of refrigeration cycle, after, according to the needs of each chamber, row freezes respectively or closes down compressor again.
The embodiment that Fig. 2 represents is another working method of the three temperature refrigerator circulatory systems.Its device is described basic identical with Fig. 1, just increased a secondary capillary in the front of magnetic valve B, and the second secondary inlet capillaceous connects the first secondary outlet capillaceous.Like this, just got rid of the possibility that first evaporimeter and second evaporimeter freeze simultaneously.After cold-producing medium flows out from main capillary, by magnetic valve A, flow into first evaporimeter successively and the 3rd evaporimeter freezes, second evaporimeter since the essentially no cold-producing medium of flow resistance effect of secondary capillary a pass through.After first chamber reaches design temperature, magnetic valve A closes, cold-producing medium carries out kind of refrigeration cycle by second evaporimeter and the 3rd evaporimeter successively, after the chamber reaches design temperature between the second evaporimeter place, magnetic valve B also closes, cold-producing medium just carries out kind of refrigeration cycle by directly feeding the 3rd evaporimeter after the secondary capillary b throttling for the third time, and after the 3rd chamber reached design temperature, compressor was mended cold to other chambers or is closed.
The embodiment that Fig. 3 represents is the kind of refrigeration cycle mode of another kind of three temperature refrigerators.Its device is same as in figure 1, only with a secondary capillary, but connected mode is inequality, and cold-producing medium is after main capillary outflow, flow into first evaporimeter successively and the 3rd evaporimeter freezes through magnetic valve A, second evaporimeter then since the essentially no cold-producing medium of flow resistance effect pass through.After the chamber reached design temperature between the first evaporimeter place, magnetic valve A closed, and cold-producing medium enters second evaporimeter after the throttling once more through secondary capillary, and flowed into compressor inlet through the 3rd evaporimeter, and this moment, magnetic valve B was in closed condition.After the chamber reaches design temperature between the second evaporimeter place, magnetic valve B opens, cold-producing medium then freezes because of the gravity effect directly enters the 3rd evaporimeter, second evaporimeter is seldom measured in addition and is gaseous state and vaporific cold-producing medium particulate inflow simultaneously, thereby the temperature recovery of the chamber between the second evaporimeter place of having slowed down, after the chamber reaches design temperature between the 3rd evaporimeter, as required other evaporimeter is mended cold or close compressor again.
The embodiment that Fig. 4 represents is the 4th a kind of kind of refrigeration cycle mode of three temperature refrigerators.Its device is basic identical with Fig. 1, but its structure is then with preceding totally different.Cold-producing medium is behind main capillary-compensated, can simultaneously or feed first evaporimeter by turns and second evaporimeter freezes, flow into compressor inlet then respectively, the 3rd evaporimeter is then because secondary flow resistance effect capillaceous, have only when first chamber and second chamber to reach design temperature and magnetic valve A, B are all given close Shi Caihui refrigeration takes place, at this moment, cold-producing medium flows into the air inlet of compressor from the outlet of the 3rd evaporimeter, therefore, three evaporimeters are in parallel.
Embodiment illustrated in fig. 5, its endless form and shown in Figure 4 basic identical has just increased by one section secondary capillary in magnetic valve B front.Like this, first evaporimeter and second evaporimeter just can not obtain cold simultaneously, but can make second evaporimeter and the 3rd evaporimeter reach lower evaporating temperature, and its scope of application is wideer.
In the embodiment shown in fig. 6, then need not secondary capillary, and three evaporimeters are in series, and two magnetic valves all play bypass action.When cold-producing medium after main capillary-compensated, by first evaporimeter, second evaporimeter and the 3rd evaporimeter freezed in chamber between three successively, flow into compressor inlet then and form circulating system.At this moment, two magnetic valves all are in closed condition.After first chamber reaches design temperature, magnetic valve A opens, liquid refrigerant directly enters second evaporimeter because of the gravity effect, again behind the 3rd evaporimeter, flow to compressor inlet, still have a small amount of atomized refrigerant particulate along with gaseous refrigerant enters first evaporimeter this moment, to slow down the rise of the first room temperature degree.After second chamber reaches design temperature, magnetic valve B continues to open, cold-producing medium freezes because of the gravity effect directly enters the 3rd evaporimeter, this moment, first evaporimeter and second evaporimeter also can obtain a little cold and the rise of this room temperature degree that slows down, after the 3rd evaporimeter reaches design temperature, mend cold or close compressor for again other chambers.
