Put 5 by the second preposition for the vapor phase refrigerant derivation of the gas-liquid two-phase cold-producing medium after throttling to compressor 1 capillary throttle device
8, and liquid refrigerant enter micro-channel evaporator 6, liquid refrigerant compared with gas-liquid two-phase cold-producing medium at micro-channel evaporator
Flow distribution process in separatory manifold, would be even more beneficial to the uniform separatory of micro-channel evaporator.
In the refrigerating circuit of the present invention, the connection pipeline of gas-liquid separation device 5 and compressor 1 is provided with the second capillary
Pipe throttling arrangement 8, rather than use opening features (such as opening valve) etc..After the hypotensive effect that capillary tube is bigger may insure that throttling
Gas-liquid two-phase cold-producing medium in gaseous refrigerant enter compressor 1 rather than actively induction throttling by gas-liquid separation device 5
After the liquid phase actively shwoot of gas-liquid two-phase cold-producing medium become gaseous state, enter compressor 1 via gas-liquid separation device 5.After throttling
Gas-liquid two-phase cold-producing medium in liquid phase micro-channel evaporator to be entered 6 be not evaporated heat exchange and obtain cold and be only the right way, and not
It is active shwoot, actively enters compressor 1.
In the refrigerating circuit of the present invention, it is responsible at the feed liquor of micro-channel evaporator 6 and adds with flute type separating tube 61, flute
Type separating tube 61, by inside and outside two-layer bushing type hydrostatic, advantageously in liquid phase refrigerant micro-channel evaporator 6 point
Uniform separatory in liquid manifold.
Generally, Northeast Cold Area outdoor temperature in winter too low (less than-10 DEG C).Under lower temperature operating mode, routine sets
The condenser of meter cannot normally work, and cold-producing medium flow regime is undesirable, and compressor 1 cannot be properly functioning, thus causes refrigeration
System cannot be properly functioning.Therefore, this refrigerating circuit of Northeast Cold Area runs and must consider seasonal factor by emphasis, and equipment is main
Running for cooling in summer, the equipment of transition season runs to be needed in 25 DEG C of work carried out above of outdoor environment temperature.
Generally, Guangdong tropical summer outdoor environment temperature too high (more than 43 DEG C).Under higher ambient temperature conditions,
The condenser of conventional design cannot normally work, and cold-producing medium flow regime is not ideal enough, and compressor 1 excessive discharge temperature cannot be just
Often run, thus cause the refrigeration system cannot be properly functioning.Normally use to meet refrigeration system, need to optimize condenser
Design, increase Liquid injection cooling parts etc., it is ensured that this refrigeration system is needing the safe and stable operation in season of refrigeration.

It is 7:1 that capillary tube is wound around the ratio of volume number, and the first capillary throttle device 4 pressure drop is closely 7 times of the second capillary throttle device 8,
Second capillary throttle device 8 pressure drop is less, is conducive to balance from the cold-producing medium of micro-channel evaporator 6 outflow with from the second capillary
Pressure between the cold-producing medium that pipe throttling arrangement 8 flows out.
In another preferred embodiment of the invention, the first capillary throttle device 4 and the second capillary throttle device 8
It is 10:1 that capillary tube is wound around the ratio of volume number, and the pressure drop of the first capillary throttle device 4 is closely the 10 of the second capillary throttle device 8
Times, fully the refrigerant pressure that will enter gas-liquid separation device 5 is reduced, be more beneficial for cold-producing medium at micro-channel evaporator 6
Evaporation.
The cyclic process on logP-h figure of the blood circulation of the present invention as it is shown in figure 5, in Fig. 5 number designation be all for
For the state of cold-producing medium, wherein, state point 1 represents that cold-producing medium is in superheat state, prevents cold-producing medium from producing in compressor
Liquid hit phenomenon；State point 2 is after the compression of compressor 1, and the state of cold-producing medium is high-pressure gaseous；Pass through micro-channel condenser
2, the state of cold-producing medium becomes state point 3, and state is high-pressure liquid, is become by liquid point 3 after entering the first capillary throttle device 4
For the gas-liquid mixture phase of state point 4, after gas-liquid separation device 5, by gas-liquid separation device 5 side cold-producing medium out in
The liquid of state point 5, this some refrigerant enters micro-channel evaporator 6, after micro-channel evaporator 6 heat exchange is evaporated, becomes shape
State point 6, and subsequently enter compressor 1；And by gas-liquid separation device 5 top gaseous refrigerant out through the second throttling arrangement
After 8 reducing pressure by regulating flows, cold-producing medium with state point 6 becomes state point 1 after converging, and enters compressor 1, completes whole circulation.
Below it is only the explanation of the introduction to the specific embodiment of the invention, in order to technical solution of the present invention to be described, but the present invention
Protection domain be not limited in above example, as long as person skilled carries out equivalent to technical characteristic or changes
