Description
Technical field
The present invention relates to A/C evaporator field, specifically a kind of cool-storage type tube-fin evaporator.
Background technology
In refrigeration air-conditioner, tube-fin evaporator is important component therein, and effect is the liquid refrigeration of low temperature
Agent is circulated in finned tube, and outside air circulates outside pipe between fin, and the liquid refrigerant of low temperature is sent out with air by finned tube
Heat exchanges, and liquid refrigerant heat absorption evaporation, air themperature reduces, and is finally reached the purpose to cool down in room；Under room temperature
Drop, it is meant that the evaporating temperature of refrigeration system is declined, and under the conditions of identical outdoor temperature, the evaporation temperature of refrigeration system
Degree declines, and Energy Efficiency Ratio is to decline, and evaporating temperature is maintained higher level, is conducive to the energy saving of refrigeration system.
In the control logic of fixed frequency air conditioner, after the air themperature in room drops to set temperature, refrigeration system will
It shuts down, after room temperature rises to a certain range, is again started up refrigeration system, this will bring temperature fluctuation in room larger,
The start and stop of refrigeration compressor are more frequent, the shortcomings of easily failure.
The object of the present invention is to provide a kind of cool-storage type tube-fin evaporators for invention content, can maintain air-conditioning evaporation
Temperature does not reduce persistently, so that refrigeration system is operated in the higher conditioned area of Energy Efficiency Ratio, and can gently room temperature fluctuate, reduces
The start-stop time of compressor extends the refrigeration system service life.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of cool-storage type tube-fin evaporator includes the pipe for flowing of refrigerant road between two symmetrical side plates, refrigerant stream
There are refrigerant, pipe for flowing of refrigerant road both ends to be connect respectively with external refrigeration system in siphunculus road, pipe for flowing of refrigerant road outer wall
Fin, heat exchange between fin and pipe for flowing of refrigerant road are installed, it is characterised in that：Further include be mounted on two symmetrical side plates it
Between cool storage material filling tube, have solid-liquid phase change cool storage material in cool storage material filling tube, cool storage material filling tube not with outside
Connection, heat exchange between cool storage material filling tube and fin.
A kind of cool-storage type tube-fin evaporator, it is characterised in that：The pipe for flowing of refrigerant on air-flow direction
Road is located at front, and cool storage material filling tube is located at the rear on pipe for flowing of refrigerant road, i.e. air first passes through pipe for flowing of refrigerant road
Using cool storage material filling tube.
A kind of cool-storage type tube-fin evaporator, it is characterised in that：Cool storage material filling tube is closed at both ends, to realize
Cool storage material filling tube is not connected to outside.
A kind of cool-storage type tube-fin evaporator, it is characterised in that：Solid-liquid phase change cool storage material is tamped in coolness storing material
Expect in filling tube, so that solid-liquid phase change cool storage material does not flow.
A kind of cool-storage type tube-fin evaporator, it is characterised in that：Cool storage material filling tube contacts with each other with fin,
Or fin is similarly installed at the filling pipe outer wall of cool storage material, to realize heat exchange between cool storage material filling tube and fin.
A kind of cool-storage type tube-fin evaporator, it is characterised in that：The solid-liquid phase change cool storage material be water or
Paraffin.
In the present invention, cool-storage type tube-fin evaporator is when refrigeration system works, when room temperature declines, in evaporator
The evaporating temperature of refrigerant accordingly declines, Gu the transformation temperature of-liquid phase-change material for cold storage is arranged in suitable temperature spot, works as evaporation
When temperature drops to the temperature spot, indicate that room temperature has dropped to a certain degree, cool storage material can start phase change cold-storage, steam
Hair temperature no longer continues to decline within the cold-storage period, does not influence the cooling of space air；Cold-storage starts that refrigeration system work can be extended
The time of work.After cool storage material completes cold-storage, refrigeration system can be shut down, and can be relied on cool storage material released cold quantity at this time, be prolonged
The downtime of long refrigeration system.And then gentle room temperature fluctuation can be reached, the start-stop time of compressor is reduced, system is extended
The purpose in cooling system service life.
Beneficial effects of the present invention：
1, the present invention improves refrigeration system Energy Efficiency Ratio, is conducive to energy saving.
2, the present invention reduces the start-stop time of compressor, is conducive to extend the refrigeration system service life.
3, the configuration of the present invention is simple, easy for installation, easily fabricated, failure rate is low, safe and reliable.
4, the present invention is applied widely, can be widely applied to various air-conditioning refrigeration systems.

Fig. 1 is structure of the invention front view.
Fig. 2 is structure of the invention left view.
Fig. 3 is structure of the invention right view.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1-Figure 3, a kind of cool-storage type tube-fin evaporator includes the refrigeration between two symmetrical side plates 1
Agent flow pipe 2 has in pipe for flowing of refrigerant road 2 refrigerant, 2 both ends of pipe for flowing of refrigerant road to connect respectively with external refrigeration system
It connects, 2 outer wall of pipe for flowing of refrigerant road is equipped with fin 3, and heat exchange between fin 3 and pipe for flowing of refrigerant road 2 further includes installation
Cool storage material filling tube 4 between two symmetrical side plates 1 has solid-liquid phase change cool storage material 5, cold-storage in cool storage material filling tube 4
Material filling tube 4 is not connected to outside, heat exchange between cool storage material filling tube 4 and fin 3.
Pipe for flowing of refrigerant road 2 is located at front on air-flow direction A, and cool storage material filling tube 4 is located at refrigerant stream
The rear on siphunculus road 2, i.e. air first pass through pipe for flowing of refrigerant road 2 using cool storage material filling tube 4.
Cool storage material filling tube 4 is closed at both ends, to realize that cool storage material filling tube 4 is not connected to outside.
Solid-liquid phase change cool storage material 5 tamps in cool storage material filling tube 4, so that solid-liquid phase change cool storage material 5 is not sent out
Raw flowing.
Cool storage material filling tube 4 contacts with each other with fin 3 or fin 3 is similarly installed at outside cool storage material filling tube 4
Wall, to realize heat exchange between cool storage material filling tube 4 and fin 3.
Solid-liquid phase change cool storage material 5 is water or paraffin.
The present invention is fin-tube type heat exchanger, is made of side plate, fin and pipeline.Pipeline be divided into pipe for flowing of refrigerant road with
And cool storage material filling tube, pipe for flowing of refrigerant road connect refrigeration system pipeline, refrigerant flows in pipeline, and cool storage material
Pipe is only used for filling cool storage material, does not occur flow phenomenon, air-flow direction be first pass through pipe for flowing of refrigerant road using
Cool storage material filling tube, when cold-storage carries out, cold is transferred to cool storage material filling tube by fin from pipe for flowing of refrigerant road.
In conclusion when ambient temperature is relatively low, and need to cool down in shelter, while not allowing extraneous cold wind straight again
When tapping into cabin, it can be not turned on compressor cooling, the exchange of indoor and outdoor heat is directly realized through the invention, reduce
Energy consumption.
