In order to reach the foregoing invention purpose, the technical solution of the utility model realizes as follows:
Bidirectional over-cooling liquid container, it comprises fluid reservoir and places the interior heat exchanger of fluid reservoir.Its design feature is, described fluid reservoir is built-in with four adapters, wherein taking over one directly communicates with fluid reservoir inside, take over two and take over three and be communicated with a side cooling circuit of heat exchanger, take over four and be communicated with the opposite side of heat exchanger loop one end that is cooled, the be cooled other end in loop of the opposite side of heat exchanger communicates with fluid reservoir inside.
In above-mentioned bidirectional over-cooling liquid container, the outline of described fluid reservoir is vertical shape, and the external tapping of four adapters places the top of fluid reservoir.Described heat exchanger is the coaxial sleeve tube heat exchanger.
In above-mentioned bidirectional over-cooling liquid container, the outline of described fluid reservoir is horizontal shape, and the external tapping of four adapters places the side of fluid reservoir.Described heat exchanger is the coaxial sleeve tube heat exchanger.
The utility model is owing to having adopted technique scheme, heat exchanger to be placed directly in the fluid reservoir and being immersed in the cold-producing medium multiplication of heat exchange effect, can obtain bigger degree of supercooling, can reach the accurate control of degree of supercooling, improve the efficiency and the stability of system, reduce equipment cost greatly.

Fig. 1 is a structural principle schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model embodiment 1;
Fig. 3 is the structural representation of the utility model embodiment 2;
Fig. 4 is the structural representation of the utility model practical application in the air-conditioning unit.
The specific embodiment
Referring to Fig. 1, the utility model comprises fluid reservoir 1 and the heat exchanger 6 that places in the fluid reservoir 1.Fluid reservoir 1 is built-in with four adapters, wherein taking over 1 directly communicates with fluid reservoir 1 inside, take over 23 and take over 34 and be communicated with a side cooling circuit of heat exchanger 6, take over 45 and be communicated with the opposite side of heat exchanger 6 loop one end that is cooled, the be cooled other end in loop of the opposite side of heat exchanger 6 communicates with fluid reservoir 1 inside.
Referring to Fig. 2 and Fig. 4, the outline of fluid reservoir 1 is vertical shape in the present embodiment 1, and the external tapping of four adapters places the top of fluid reservoir 1, and heat exchanger 6 is the coaxial sleeve tube heat exchanger.
Cooling condition: most of cold-producing medium of discharging from outdoor heat exchanger enters in the fluid reservoir 1 through check valve and adapter 1, and accumulates in fluid reservoir 1 inner bottom part.The fraction cold-producing medium of being discharged by outdoor heat exchanger enters adapter 23 after being arranged on the flow controller one first throttling of taking over before 23, enter then with the shell side 61 of taking over the 23 coaxial sleeve heat exchangers 6 that are communicated with in, by the higher liquid refrigerant of temperature in the shell side 61 outside wall surface coolings fluid reservoir 1.Enter in heat exchanger 6 tube sides 62 through the liquid refrigerant of precooling, the low cold-producing medium of temperature cools off liquid in the tube side 62 once more by shell side 61 inside pipe wall faces in the shell side 61.Tube side 62 inner refrigerants flow into the adapter 45 that is communicated with it after reaching certain degree of supercooling, enter indoor set by taking over 45 discharge backs by pipeline.Become two-phase mixture behind the shell side 61 inner refrigerants absorption heat and enter refrigeration air-conditioner unit gas-liquid separator or other containers of system by taking over 34.Can accurately control outflow fluid reservoir 1 cold-producing medium degree of supercooling by regulating the flow controller of taking over before 23 one.
Heating condition: most of cold-producing medium of discharging from indoor heat exchanger enters in the tube side 62 of coaxial sleeve heat exchanger 6 through taking over 45, flowed in the fluid reservoir 1 after the refrigerant cools that temperature is lower in heat exchanger 6 shell sides 61, assembled at fluid reservoir 1 inner bottom part through the cold-producing medium of precooling.The cold-producing medium that temperature are lower in the shell side 61 absorbs the heat of the refrigerant liquid of precooling in fluid reservoir 1 by its outside wall surface, and the cold-producing medium in the fluid reservoir 1 is cooled off once more, discharges fluid reservoirs 1 by taking over 1 after reaching certain degree of supercooling.Major part is crossed cold cold-producing medium by pipeline inlet chamber external heat exchanger, the small part cold-producing medium by taking over 23 shell sides 61 that enter heat exchanger 6, absorbs and becomes two-phase mixture behind the higher cold-producing medium heat of temperature and enter refrigeration air-conditioner unit gas-liquid separator or other containers of system by taking over 34 after flow controller two throttlings.Can accurately control outflow fluid reservoir 1 cold-producing medium degree of supercooling by regulating the flow controller of taking over before 23 two.
Referring to Fig. 3 and Fig. 4, the outline of fluid reservoir 1 is horizontal shape in the present embodiment 2, and the external tapping of four adapters places the side of fluid reservoir 1, and heat exchanger 6 is the coaxial sleeve tube heat exchanger.
The topology layout of other device and cold-producing medium flow process are identical with embodiment 1 among the embodiment 2, seldom give unnecessary details at this.
What deserves to be explained is, according to above-mentioned technical scheme, if be other arbitrary shape, perhaps with the heat exchanger of heat exchanger 6 other forms of employing, as plate type heat exchanger etc. the alteration of form of fluid reservoir 1.Formed technical scheme like that all belongs to protection domain of the present utility model.
