Specific implementation mode
Below based on embodiment, present invention is described, but the present invention is not restricted to these embodiments.Under
Text to the present invention datail description in, it is detailed to describe some specific detail sections.Do not have for a person skilled in the art
The description of these detail sections can also understand the present invention completely.In order to avoid obscuring the essence of the present invention, well known method, mistake
There is no narrations in detail for journey, flow, element.
In addition, it should be understood by one skilled in the art that provided herein attached drawing be provided to explanation purpose, and
What attached drawing was not necessarily drawn to scale.
Unless the context clearly requires otherwise, "include", "comprise" otherwise throughout the specification and claims etc. are similar
Word should be construed as the meaning for including rather than exclusive or exhaustive meaning；That is, being containing for " including but not limited to "
Justice.
In the description of the present invention, it is to be understood that, term " first ", " second " etc. are used for description purposes only, without
It can be interpreted as indicating or implying relative importance.In addition, in the description of the present invention, unless otherwise indicated, the meaning of " multiple "
It is two or more.
As shown in Figure 1, dry filtrating equipment 10 provided by the invention includes first filter 11 and protection pipeline 12, it is described
First filter 11 is in parallel with protection pipeline 12, and the first filter 11 and the both ends of protection pipeline 12 pass through two three respectively
It is logical to be attached.Preferably, the first filter 11 be device for drying and filtering, further preferably totally-enclosed device for drying and filtering,
I.e. the first filter 11 is internally provided with dry element (such as drier) and filter element, and the first filter 11 is used
In removing the moisture in refrigerant, meanwhile, the refrigerant filtration that the first filter 11 can also be to flowing through.By to described
The structure size of protection pipeline 12 is configured, and makes at least partly refrigerant that can flow through the first filter 11, and when described the
After one filter, 11 cisco unity malfunction, the flow of the protection pipeline 12 disclosure satisfy that demand.Wherein, the knot of pipeline 12 is protected
Structure size includes the length etc. protected the internal diameter of pipeline 12, protect pipeline 12.Preferably, the first filter 11 and protection pipe
A vent diverter is respectively connected at both ends after 12 parallel connection of road, by the vent diverter to flowing through the first filter 11 and protecting
The cold medium flux on pillar road 12 is controlled.
Due to being provided with drier in the first filter 11, the first filter 11 is with protection pipeline 12 to refrigerant
Resistance it is different, so, when refrigerant flow to the dry filtrating equipment 10, have it is more flow through the protection pipeline 12,
Less flows through the first filter 11.Preferably, the refrigerant for flowing through the first filter 11 accounts for the 1/3 of total amount, flows through
The refrigerant of the protection pipeline 12 accounts for the 2/3 of total amount, further, above-mentioned to flow through the first filter 11 and protection pipeline 12
Cold medium flux can change with the extension of 10 working time of the dry filtrating equipment, i.e., with the first filter
The amount that drier in 11 absorbs moisture is more and more, and drier water swelling gap is smaller and smaller, and the flow of refrigerant is increasingly
It is small, meanwhile, the cold medium flux of the protection pipeline 12 can be increasing, and the cold medium flux of the protection pipeline 12 can ensure just
Often work.Since contained humidity is seldom in refrigerant, and, moisture is remaining when being assembly, will not generate water again during the work time
Point, the moisture after recycling several times in refrigerant has been absorbed by the drier in the first filter 11 substantially, so working as
The first filter 11 because internal desiccant absorbs moisture influences that first filtering can not also be replaced when refrigerant circulates
Device 11, and filtering for task can be undertaken by the filter of other in the heat pump system using it.
As shown in Fig. 2, in another embodiment, it is additionally provided with the second filter 121 on the protection pipeline 12, described
The preferably bag filter of tow filtrator 121, further preferably totally-enclosed bag filter, second filter 121
After setting makes the first filter 11 fail, the dry filtrating equipment 10 still has filtering function.
As shown in figure 3, the heat pump system for being provided with dry filtrating equipment 10 of the present invention include outdoor heat exchanger 1, it is dried
Device 10, restricting element 2 and indoor heat exchanger 3 are filtered, the outdoor heat exchanger 1 connects the dry filtrating equipment 10, described dry
Dry filter device 10 connects the restricting element 2, and the restricting element 2 connects the indoor heat exchanger 3.
In process of refrigerastion, refrigerant enters the dry filtrating equipment 10, part stream after being flowed out in outdoor heat exchanger 1
Through the first filter 11, a part flows through the protection pipeline 12, flows through the first filter 11 and protection pipeline 12
Afterwards, refrigerant converges, and by restricting element 2, the refrigerant for flowing through the restricting element 2 gets in 3 evaporation endothermic of heat exchanger.
Refrigerant is voluntarily shunted according to the resistance that the first filter 11 and protection pipeline 12 circulate to refrigerant, it is preferable that
The refrigerant that 1/3 refrigerant flows through the first filter 11,2/3 flows through the protection pipeline 12.Flow through the first filter
Moisture in 11 refrigerant is absorbed by the drier in the first filter 11, and the impurity in refrigerant is by the first filter
Filter device in 11 filters out, and flows through the impurity in the refrigerant of the protection pipeline 12 by second on the protection pipeline 12
Filter 121 filters out.With the increase of the amount for the refrigerant for flowing through the first filter 11, done in the first filter 11
Drying prescription absorption moisture is more and more, and moisture is fewer and fewer in refrigerant, and drier water swelling post gap is smaller and smaller, flows through described
The cold medium flux of first filter 11 is also smaller and smaller, and the cold medium flux for flowing through the protection pipeline 12 is increasing.
It has been absorbed by the drier in the first filter 11 since the moisture in refrigerant at this time is most of, in refrigerant
Moisture it is very low, can not consider influence of the moisture to system normal operation, so, need not be further continued for cold
Matchmaker is dried, and 10 need of the dry filtrating equipment filter refrigerant by the second filter 121 on the protection pipeline 12
In impurity be can guarantee system normal operation.
Heat pump system of the present invention is in heating in the operation principle and above-mentioned process of refrigerastion of the dry filtrating equipment 10
Operation principle is identical, and only the flow direction of refrigerant is opposite.No longer the heating operations of the heat pump system are described in detail herein.
Dry filtrating equipment and heat pump system provided by the invention, protection pipeline in parallel, works as drying on device for drying and filtering
When filter is due to absorbing moisture and cisco unity malfunction, protection pipeline connected in parallel also ensures the normal operation of system,
And device for drying and filtering need not be replaced, it ensure that the stability of system operation, reduce the frequency of system maintenance.
Those skilled in the art will readily recognize that under the premise of not conflicting, above-mentioned each preferred embodiment can be free
Ground combination, superposition.
It should be appreciated that above-mentioned embodiment is merely exemplary, and not restrictive, without departing from the basic of the present invention
In the case of principle, those skilled in the art can be directed to the various apparent or equivalent modification or replace that above-mentioned details be made
It changes, is all included in scope of the presently claimed invention.
