Abstract
The utility model discloses a high efficiency energy saving split-flow device belonging to the field of refrigeration air-conditioners. The device includes a split-flow pipe, a distributor and a distributor connection pipe, the distributor connection pipe is welded on the inlet of the distributor, one end of the split-flow pipe is welded on the outlet of the distributor and the other end is connected to an evaporator; the distributor connection pipe is a high efficient micro fin pipe. The beneficial effects of the utility model are that the flow state of the refrigerant in the refrigeration system can be changed by the high efficient micro fin pipe, so the layered wave-like flow of the refrigeration system is changed into spiral ring-like flow by the high efficient micro fin pipe to increase heat exchange area, accelerate the flow velocity of refrigerant and improve the heat exchange efficiency of the evaporator coil pipe, thereby achieving the aim of improving the refrigeration capability of the whole refrigeration system; in addition, the device enables a more stable operating temperature of the refrigeration system, reduces the defrosting frequency, each defrosting time and the unnecessary defrosting period of compressors, as well as greatly improves the use efficiency of refrigeration equipment, thereby achieving the effects of saving electricity and prolonging the use time of equipment.
Description
Technical field
The invention belongs to the refrigeration and air-conditioning technical field.Specifically a kind of energy-efficient part flow arrangement
Background technology
The distributor weld assembly generally is installed on the import department of heat exchanger, mainly be for the vapour-liquid two-phase mixture after the throttling being evenly distributed in each loop of heat exchanger, realize uniform heat exchange, improve the heat exchange efficiency of heat exchanger, avoid causing the heat exchanger heat exchange efficiency low, cause the waste of the energy because of cold-producing medium distributes inequality.
And the smooth tubes that the distributor tube connector in the distributor weld assembly all uses inner wall smooth usually as shown in Figure 2, because of the convenience and low the making of price of its buying more is people's acceptance.Because the smooth tubes inner wall smooth does not have perturbation to the cold-producing medium of flowing through, so the distributed layer wave flow of cold-producing medium in pipe seen Fig. 4.Middle liquid refrigerant, the gaseous refrigerant on upper strata and following refrigeration oil present layer distributed, occur each loop easily and distribute uneven phenomenon through distributor the time, the heat exchanger heat exchange efficiency descends, and pressure-drop in pipeline increases, cause the refrigeration unit refrigerating capacity low, energy loss is big; Outdoor heat exchanger can be because distribute inequality to cause each loop frosting, defrost inhomogeneous in the winter time, pressures cycle reduces, cause heat exchanger frosting, defrost frequent, reduced the service efficiency of refrigeration unit, influence unit service life and, make human body sensory uncomfortable having increased the fluctuation of indoor environment temperature.
Summary of the invention
The invention provides a kind of energy-efficient part flow arrangement; Can change refrigeration system internal refrigeration storage agent flow regime, improve the heat exchange efficiency of evaporator coil, thereby reached the purpose that improves whole refrigeration system refrigerating capacity.
The present invention realizes with following technical scheme: a kind of energy-efficient part flow arrangement comprises isocon, distributor and distributor connecting leg; The distributor tube connector is welded on the inlet of distributor, and isocon is welded on that the other end is connected with evaporimeter in the outlet of distributor; Described distributor tube connector is efficient little fin pipe.
Efficient little fin pipe the invention has the beneficial effects as follows: owing to can change refrigeration system internal refrigeration storage agent flow regime, the layering wave flow of refrigeration system is become spiral ring stream by efficient little fin pipe, increased heat exchange area, accelerated refrigerant flow rate, improve the heat exchange efficiency of evaporator coil, thereby reached the purpose that improves whole refrigeration system refrigerating capacity.In addition, it can also make that the refrigeration system operating temperature is more stable, reduces the number of times of compressor defrosting, reduce the time of each compressor defrosting, reduce unnecessary defrosting cycle, improved the service efficiency of refrigeration plant greatly, thereby reach economize on electricity, prolong the equipment effect of service time.

Fig. 5 is the annular flow schematic diagram that cold-producing medium flows in efficient little fin pipe.
Among the figure: 1, isocon, 2, distributor, 3, the distributor tube connector.
The specific embodiment
As shown in Figure 1, energy-efficient part flow arrangement is made up of isocon 1, distributor 2 and distributor tube connector 3.Distributor tube connector 3 is welded on the inlet of distributor, and isocon 1 is welded in the outlet of distributor, and the other end is connected with evaporimeter.Distributor tube connector 3 adopts efficient little fin pipe, structure as shown in Figure 3, efficient little fin inside pipe wall is a helical form.
As shown in Figure 5, efficient little fin pipe 3 can change refrigeration system internal refrigeration storage agent flow regime, the layering wave flow of refrigeration system is become spiral ring stream by efficient little fin pipe, increased heat exchange area, accelerated refrigerant flow rate, improve the heat exchange efficiency of evaporator coil, thereby reached the purpose that improves whole refrigeration system refrigerating capacity.Can reduce the number of times of compressor defrosting winter, reduce the time of each compressor defrosting, reduce unnecessary defrosting cycle, improve the service efficiency of refrigeration plant greatly, thereby reach economize on electricity, the prolongation equipment effect of service time.
