Description
Technical field
The present invention relates to a kind of evaporators of adjustable refrigerant flow, are used for air source heat pump and air-conditioning system.
Background technology
With the development of the social economy, traditional coal-burning boiler heating mode is restricted by energy and environment various aspects,
Emerging heating mode attracts attention.As one kind in decentralized heating mode, air source heat pump has flexible for installation, efficient section
Can, without exhaust emission the advantages of, be widely used in China Yangtze river basin, Yellow River basin.However, air source heat pump is with outdoor air
As heat source, in the case that air themperature is lower heat when, heating capacity can be faced and the problem of coefficient of performance in heating declines, very
It is unable to operate normally to meeting because flow distribution of refrigerant is unreasonable.
In addition, air source heat pump system is in application process, operating mode variation range is larger, common throttle mechanism such as heating power
Expansion valve and capillary etc. are gradually substituted by electric expansion valve.Control algolithm and the aperture setting of electric expansion valve are long for system
Phase is stable, Effec-tive Function and to be rapidly achieved stable state most important.Inappropriate electronic expansion valve controls algorithm can make
Compressor operating is degrading in system, the reduction of system working efficiency is resulted even in, to limit air source heat pump in the north
Cold and severe cold area application.
The prior art is adjusted to exist and be exchanged heat by distributor and each bypass flow of each branch shunting capillary solution of welding
Each branch outlet refrigerant temperature of device differs greatly problem.
For on heat exchanger, in forced convertion on heat exchanger the high branch refrigerant of wind pressure can heat-absorption air heat very well,
And evaporation of fully absorbing heat is failed for the small branch refrigerant of wind pressure, then branch way outlet cryogenic temperature can be caused relatively low.
Its disadvantage：Since the multiple tap hole machining accuracies of distributor are inconsistent, isocon insertion depth is inconsistent and welding
To neutral difference and each branch shunting capillary pipe length and possible pipe range difference of each branch on internal diameter flexural deformation difference, heat exchanger etc.
Reason and cause each branch to be difficult balanced flow size.
Invention content
Defect present in for the above-mentioned prior art, technical problem to be solved in the utility model are in evaporator wing
Increase a kind of assignment of traffic adjuster between piece and refrigerant inlet, solves each branch outlet temperature and requiring temperature range, from
And improve heat exchange area.
Problem to be solved in the utility model can be realized by following scheme：A kind of adjustable refrigerant flow
Evaporator, including refrigerant inlet, evaporator fin, pipeline, refrigerant outlet, which is characterized in that in refrigerant inlet and
Assignment of traffic adjuster is housed, assignment of traffic adjuster is made of valve body, spool, sealing ring, valve deck, valve between evaporator fin
A refrigerant inlet is set on the left of body, upside sets a refrigerant outlet, and right side sets one-dimensional cavetto hole, and valve body right hand external is equipped with outer spiral shell
Line is connect with the internal thread of valve deck, and secondary seal is carried out to adjuster；The left side of spool be taper, right side be equipped with external screw thread with
The internal thread of valve body is engaged, and the Hexagon hole by adjusting right end moves spool, can be changed between left side valve body and taper valve core
Gap is additionally provided with sealing ring to carry out flow-rate adjustment between spool and valve body, prevent refrigerant from being leaked from right side.
Using advantageous effect caused by the utility model：Heat exchanger flow is adjusted, using being arranged in each branch way outlet temperature
It spends temperature-sensing probe and measures temperature value under different operating modes, and by each bypass flow of flow-rate adjustment valve regulation, control each of heat exchanger
Way outlet temperature is in prescribed limit.To improve heat exchange area, heating efficiency is increased, is achieved energy-saving and emission reduction purposes.

Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode the utility model is described in further detail：
As shown in Figure 1, the evaporator of adjustable refrigerant flow, including including refrigerant inlet 1, assignment of traffic adjuster
2, evaporator fin 3, refrigerant outlet 4, the assignment of traffic adjuster 2 be located at refrigerant inlet 1 and evaporator fin 3 it
Between.
The assignment of traffic adjuster 2 is made of valve body 21, spool 22, sealing ring 23, valve deck 24, and 21 left side of valve body is set
One refrigerant inlet, upside set a refrigerant outlet, and right side sets one-dimensional cavetto hole, and spanner is entered by this circular hole in spool 22
Hexagon ring, to the relative position of adjusting spool 22；21 right hand external of valve body is equipped with external screw thread, connects with the internal thread of valve deck 24
It connects, secondary seal is carried out to adjuster；The left side of spool 22 is taper, and the internal thread that right side is equipped with external screw thread and valve body 21 is stung
It closes, right end is equipped with Hexagon hole, and the Hexagon hole by adjusting right end moves spool 22, and 21 left side of valve body and spool 22 can be changed
The gap of taper is additionally provided with sealing ring 23, prevents refrigerant from right side to carry out flow-rate adjustment between spool 22 and valve body 21
Leakage.
Utility model works principle is as follows：When refrigerant passes through evaporator, since evaporator is by air quantity difference, it can cause
The refrigerant temperature for flowing through evaporator is different, when temperature-sensing probe detects each road temperature difference, by manual modulation valve core 22,
Change the gap between valve body 21 and spool 22, controls refrigerant flow, so that the temperature in each circuit is reached close, system energy efficiency reaches
To highest.Ensure that each branch is requiring temperature range in evaporator outlet temperature control by each bypass flow regulating valve, exchanges heat
Area is not fully exerted, and improves systematic energy efficiency ratio, returns to compressor refrigerant quality and temperature is improved.
