The utility model provides a two-way flow variable knockout can not produce too big pressure drop when refrigeration, arouses the decline of refrigerating output, and when heating, the pressure drop of production can form the turbulent flow to make and divide the liquid even, do not influence the heating capacity. And the turbulent flow can increase the heat exchange efficiency of the heat exchanger.
Description
The utility model belongs to refrigerating field, relates to a kind of knockout of cold-producing medium.
In refrigerated air-conditioning system, if evaporimeter wherein adopts the multichannel coil pipe, for the cold-producing medium on each road when the evaporimeter feed flow of the expansion valve in the assurance system even, between air-side heat exchanger and expansion valve, be provided with knockout, at present, cold-producing medium knockout in the refrigerating field adopts pressure drop type knockout and Venturi tube-type spreader knockout more, pressure drop type knockout is that the turbulent flow that the orifice plate by wherein forms is finished separatory, Venturi tube then is by the cross section of first slight shrinkage and the cross section deceleration diffusion that enlarges again, and depended on pressure is separatory evenly.There are some shortcomings in above-mentioned knockout:
1, therein mobile asymmetric of cold-producing medium in above-mentioned knockout, because the influence of many unpredictable factors is arranged at the aspects such as structure of the processing of parts or installation and pipeline, above-mentioned knockout is difficult for evenly the separatory of cold-producing medium in addition.
2, the heat exchanger of air side in air-cooled air conditioner, because wind speed profile is inhomogeneous, the heat-exchange capacity of each pipeline heat exchanger own has difference, can cause that then each pipeline frosting is inhomogeneous if separatory is inhomogeneous, the bottom wind speed of general air cooling heat exchanger is lower, and frosting meeting herein is thicker, thus, can be because of that water is flowed be unfavorable because the water on the slow top of bottom defrost is easy to freeze in the bottom when the defrost, finally may cause the heat exchanger heat exchange efficiency to reduce and the rhone of row's condensed water is iced and blocked up.
3, the pressure drop of knockout is bigger, this is disadvantageous for kind of refrigeration cycle, if pressure drop is excessive, can cause the gasification of part cold-producing medium, this can make specific refrigerating effect descend, but also can make the expansion valve cisco unity malfunction, if reduce the pressure drop of existing pressure drop type or Venturi type knockout, its turbulence level of raising that this system is used for heating cold-producing medium is unfavorable again.
The purpose of this utility model is to improve the deficiencies in the prior art, provide a kind of flow of the cold-producing medium that flows in one direction bigger, make its pressure drop little, and the flow of the cold-producing medium that flows on the opposite direction is less, and can improve the turbulence level of cold-producing medium on this flow direction, and on both direction flow of refrigerant separatory knockout of bidirectional variable flow rate formula uniformly all.
For achieving the above object, the utility model is taked following design:
Knockout of the present utility model includes a sleeve pipe, and it is made up of interior pipe and outer tube, and both are set-located, and is provided with an one-way flow controlling organization in described in the sleeve pipe annular space of the inside of the outside of pipe, outer tube.
When in use, this knockout is installed in the air-side heat exchanger pipeline afterwards, is connected with expansion joint, the conducting direction that makes the one-way flow controlling organization in the described annular space is to be provided with by the direction ground of air-side heat exchanger to expansion valve.When refrigeration, cold-producing medium is condensed into liquid and flows in the collector tube in the copper pipe of heat exchanger, enter expansion valve again.In the prior art, cold-producing medium flow to collector tube by pressure drop type knockout or Venturi tube-type spreader knockout, pressure drop is bigger, when using this knockout, the described knockout that is connected on the copper pipe is the state of conducting at this moment in annular space, so part of refrigerant is by flowing through in the interior pipe, another part cold-producing medium is by flowing through in the described annular space.Such structure can make the pressure drop to cold-producing medium in process of refrigerastion of well-behaved liquid device very little, generally can reduce pressure drop 50～80%, and simultaneously, separatory is also more even.When heating, refrigerant liquid goes out collector tube to evaporimeter, flows through this knockout with the direction opposite with when refrigeration, manages still conducting in described, but annular space sealed by described one-way flow controlling organization, so cold-producing medium can only be by flowing through in the interior pipe.Like this, can increase the turbulence level of cold-producing medium.Simultaneously, this knockout can form different pressure drops by the position of regulating the one-way flow controlling organization between the inner and outer pipes, to satisfy the different requirements of system.For example, in the system that many pipeline parallel connections are arranged, can set less pressure drop apart from the pipeline that fan is nearer, and can set bigger pressure drop away from the pipeline of fan, thereby make the frosting on each pipeline more even, improve heat exchange efficiency, and different pressure drops does not influence heating capacity.
The relative length of the described inner and outer pipes of this knockout can be: 1, isometric; 2, interior length of tube is greater than outer length of tube; 3, outer length of tube is greater than interior length of tube.By selecting different inner and outer pipes length to adjust heat exchange area, the degree of superheat is bigger than normal in the time of can improving heat exchange efficiency and can prevent to heat again, makes frosting even.
The bidirectional variable flow rate liquid separator that the utility model provides can not produce excessive pressure drop when refrigeration, cause the decline of refrigerating capacity, does not worry owing to the unwanted pressure drop that uses liquid-dividing head to produce.In order to overcome the defective that descends owing to pressure drop ambassador refrigerating capacity, often select expansion valve capacious in the prior art for use, and after having used this knockout, can not re-use jumbo expansion valve, the structure of this refrigerating plant is become simply, and can reduce equipment cost.When heating, the pressure drop of generation can form turbulent flow, thereby makes separatory even, does not influence heating capacity.And turbulent flow can make the heat exchange efficiency of heat exchanger increase.
