Description
Technical field
The utility model relates to a kind of refrigeration system throttling and evaporation device, the refrigeration system throttling and evaporation device that uses on particularly a kind of refrigerator.
Background technology
The refrigeration system of using on the refrigeration plant such as refrigerator, refrigerator mainly is made of compressor, condenser, throttling control assembly and evaporimeter four parts, connects successively with pipeline between four parts, forms a closed cycle system.Cold-producing medium constantly circulates in this system, and state variation takes place, thereby finishes and extraneous exchange heat.The operation principle of this refrigeration system is as follows: liquid refrigerant absorbs after the heat of the object that is cooled in evaporimeter, the steam that is vaporized into low-temp low-pressure enters condenser sucked, be compressed into the steam of high pressure-temperature by compressor after, in condenser to cooling medium (for example water or air) heat release, be condensed into highly pressurised liquid, be the cold-producing medium of low-pressure low-temperature through throttling control assembly (for example expansion valve or capillary) throttling then, and enter evaporimeter heat absorption vaporization once more, reach the purpose of circularly cooling thus.Like this, cold-producing medium is finished a kind of refrigeration cycle through pervaporation, compression, condensation, four basic processes of throttling in system.
Evaporimeter commonly used in the refrigerating plants such as refrigerator is the horizontal coiled-tube evaporimeter, that is, the coil pipe of evaporimeter roughly is horizontal level, and one encloses obliquely and from top to bottom or from the bottom to top spirals.This horizontal coiled-tube evaporimeter is mainly used in horizontal chest freezer or freezer, and described horizontal coiled-tube evaporimeter is arranged in the four sides sidewall of horizontal refrigerator or in the wall of freezer.This horizontal coiled-tube evaporimeter directly links to each other with capillary or expansion valve (throttling control assembly), and the horizontal coiled-tube evaporimeter is horizontally disposed with the end that capillary or expansion valve (throttling control assembly) link to each other.In the time of like this when the liquid refrigerant of low-temp low-pressure enters near the evaporimeter of vacuum and return line from capillary or expansion valve (throttling control assembly), because pressure abrupt change and flow resistance are big, this causes liquid refrigerant to produce very big noise when the eruption vaporization.
The utility model content
The purpose of this utility model is to provide a kind of refrigeration system throttling and evaporation device, its by reduce cold-producing medium from the throttling control assembly to evaporimeter pressure differential and reduce the flow of refrigerant resistance and reduce noise.
For achieving the above object, the refrigeration system that the utility model provides throttling and evaporation device: comprise throttling control assembly and spirally-wound horizontal coiled-tube evaporimeter, between described throttling control assembly and horizontal coiled-tube evaporimeter, be connected with transition conduit, described transition conduit be parallel to the horizontal coiled-tube evaporimeter the axis of screw or and this axis of screw between angle be acute angle.
The transition conduit that increases can reduce pressure reduction, slow down the refrigerants vaporize process, and the bending section of throttling control assembly and horizontal coiled-tube evaporimeter together upwards is provided with, make cold-producing medium to move downward along the gravity direction of self, reduce flow resistance, thereby reduced the noise that produces by the throttling and evaporation device in the refrigeration system.
Described transition conduit length is preferably greater than and equals 50mm and smaller or equal to 500mm.
Adopt the transition conduit of 50mm to 500mm length can play the effect that reduces pressure reduction, slows down the refrigerants vaporize process better.
Described transition conduit length is preferably 100mm-250mm.
Transition conduit between 100mm to 250mm is more outstanding to noise reduction, noise can be reduced to the scope that the people can receive.In scope, along with the increase of transition conduit length can obviously reduce noise, when greater than 250mm, along with the increase noise reduction of transition conduit length is relatively not too obvious less than 100mm.
Preferably, the internal diameter of described transition conduit from throttling control assembly one end to horizontal coiled-tube evaporimeter one end equal and opposite in direction or become big gradually.
The transition conduit of internal diameter unanimity is simple in structure, can reduce cost.The transition conduit internal diameter increases gradually makes that pipeline collocation transition is natural, and liquid refrigerant flows unobstructed in pipeline, can further reduce noise.
An end bending that links to each other with described transition conduit in the described horizontal coiled-tube evaporimeter, and bending tube and described transition conduit are coaxial.
If in the position bending that the horizontal coiled-tube evaporimeter links to each other with transition conduit, then may be because of connecting the unreliable sealing that reduces.And the utility model carries out bending on the horizontal coiled-tube evaporimeter, can increase the reliability of this refrigeration system with the throttling and evaporation device like this.
Angle between the axis of screw of described transition conduit and horizontal coiled-tube evaporimeter is greater than 0 ° and smaller or equal to 45 °.
Like this, liquid refrigerant can make full use of the self gravitation effect and move downward, and reduces flow resistance more effectively, makes the noise reduction effect more remarkable.
Described throttling control assembly is capillary or expansion valve.
Adopt capillary as the throttling control assembly, simple in structure and cheap.Adopt expansion valve as the throttling control assembly, the reliability height.
