The specific embodiment:
The present invention is identical complete machine structure generally, and difference is: adopt the version of the serial or parallel connection of capillary restrictor, and adopt different valve control forms, below further illustrate at this point.
Fig. 1 has illustrated to adopt better way stop valve to regulate and control three alternating temperature embodiment of capillary restrictor cascaded structure form in the alternating temperature refrigerator:
First kind of series connection situation: first capillary restrictor (6) adapted separately can be controlled cold-producing medium and be in high temperature evaporation state (about 2 ℃) in evaporimeter (3) in refrigerator refrigeration system, makes refrigerator become refrigerating chamber (10～15 ℃).
Second kind of series connection situation: first capillary restrictor (6) and second capillary restrictor (7) are when connecting, flow resistance increases, the two serial connection adapted is in refrigerator refrigeration system with it, can control cold-producing medium and in evaporimeter (3), be in nearly low-temperature evaporation state (about 24 ℃), make refrigerator become nearly refrigerating chamber (12～17 ℃).

------at this moment, by automatically controlled first stop valve (9) of closing, perhaps close first stop valve (9) simultaneously and second stop valve (10) gets final product, the assistant regulating and controlling by temperature controller just can obtain more satisfied result again.
Second kind of situation: when first capillary restrictor (6) is in parallel with second capillary restrictor (7), flow resistance reduces, the two adapted in parallel is in refrigerator refrigeration system with it, the flow resistance of throttling reduces, can control cold-producing medium and in system evaporimeter (3), be in nearly low-temperature evaporation state (about 24 ℃), make refrigerator become nearly refrigerating chamber (12～17 ℃).
-------at this moment, by automatically controlled unlatching first stop valve (9) and close second stop valve (10) and get final product, the assistant regulating and controlling by temperature controller just can obtain more satisfied result again.
The third situation: first capillary restrictor (6) and second capillary restrictor (7) are added three capillary flow controller (8) when in parallel, the flow resistance of throttling is minimum, with its three adapted in parallel in refrigerator refrigeration system, can control cold-producing medium and in system evaporimeter (3), be in high temperature temperature evaporating state (about 2 ℃), make refrigerator become refrigerating chamber (10～15 ℃).
-------at this moment opens first stop valve (9) and second stop valve (10) gets final product simultaneously by automatically controlled, and the assistant regulating and controlling by temperature controller just can obtain more satisfied result again.
Fig. 3 has illustrated to adopt two-position three way solenoid directional control valve (13) to regulate and control two alternating temperature embodiment of parallel capillary tube flow controller version in the alternating temperature refrigerator:
Two-position three way solenoid directional control valve (13) just in time points to and connects first capillary restrictor (6), make the evaporating temperature of cold-producing medium in evaporimeter (3) reach about-30 ℃, cooperate the general regulation and control of temperature controller again, make refrigerator become satisfied refrigerating chamber (18～24 ℃).As if two-position three way solenoid directional control valve (13) being commutated and connecting three capillary flow controller (8), make the evaporating temperature of cold-producing medium in evaporimeter (3) reach about 2 ℃, cooperate the general regulation and control of temperature controller again, just can make refrigerator become satisfied refrigerating chamber (10～15 ℃).
If------allows the capillary restrictor of two-position three way solenoid directional control valve (13) regulation and control series connection implement the two alternating temperatures of refrigerator also is feasible, for example: with first capillary restrictor (6) and three capillary flow controller (8) series connection, need only two ends that two outlets in the two-position three way solenoid directional control valve (13) are attempted by first capillary restrictor (6) or three capillary flow controller (8), just can reach the alternating temperature effect of capillary restrictor cascaded structure form.
