Description
Technical field
The present invention relates to technical field of heat exchangers more particularly to a kind of air-source heat exchanger systems.
Background technique
Traditional air source heat pump finned heat exchanger mostly uses greatly brass distributor to cooperate the diversion design of single separating tube,
No matter body structure uses outlet air or side air-out, and the wind speed due to finned heat exchanger far from air inlet is low, and air quantity is small,
Heating or water heating under low temperature environment, cooling liquid tube frosting situation of all unavoidable finned heat exchanger far from air inlet is serious to ask
Topic, even if when unit enters defrosting state, due to being full of liquid refrigerants, refrigerant resistance phase inside the cooling liquid tube of finned heat exchanger lower part
Also can be much larger than finned heat exchanger top, defrosting poor effect significantly increases units consumption.
It is analyzed from principle：When net for air-source heat pump units runs heating mode at low ambient temperatures, finned heat exchanger is made
For heat source side, during with air heat-exchange, especially apart from the farther away finned heat exchanger lower part of air inlet, due to process
Air quantity is minimum, the liquid refrigerants of lower part of the finned heat exchanger far from air inlet, is unable to get effective heat exchange and is evaporated to steam state, from
And cause inside the cooling liquid tube of lower part full of liquid refrigerants.Even if entering defrosting state when unit reaches defrosting condition, often
Performance is that the frost thawing on finned heat exchanger top is very fast, and the frost thawing of lower part is very slow, and under most of worst cold case, unit is moved back
Out when defrosting state, still there is remaining frost on the surface of finned heat exchanger lower part, will form ice after several periods.
Simultaneously as being full of liquid refrigerants inside the copper pipe of finned heat exchanger lower part, refrigerant resistance is compared on finned heat exchanger
Portion can be much larger, and unit enters defrosting state, and a large amount of high temperature steam state refrigerant can preferentially pass through the lesser finned heat exchanger of resistance
Top, so occurring that the defrosting of finned heat exchanger top is fast, and defrosting effect is good, the defrosting of finned heat exchanger lower part is slow, defrosting effect
Difference.
Summary of the invention
The object of the present invention is to provide a kind of air-source heat exchanger systems that can improve defrosting effect in process of refrigerastion.
To achieve the goals above, the present invention provides a kind of air-source heat exchanger system, including coolant distributor, heat exchanger
Ontology and defrosting for improving cooling liquid tube group defrosting efficiency bypass tooling, and the heat exchanger body is equipped with cooling liquid tube group, described
Cooling liquid tube group is connected to the coolant distributor by separating tube, and the defrosting bypass tooling includes check valve and connecting tube, institute
The inlet that check valve liquid outlet one end is connected to the coolant distributor is stated, described check valve one end is connected to by connecting tube
Cooling liquid tube group.
The further improvement of the technical program is that the cooling liquid tube group includes several cooling liquid tubes, several cold liquid
Guan Jun is connected to the coolant distributor by separating tube.
The further improvement of the technical program is that the cooling liquid tube is copper pipe.
The further improvement of the technical program is that the defrosting bypass tooling further includes triple valve, the triple valve difference
Connect coolant distributor, check valve and cooling liquid tube.
The further improvement of the technical program is that the heat exchanger body offers hole for hoist.
Implement the embodiment of the present invention, has the following technical effects：
The configuration of the present invention is simple, due to the effect of check valve, does not have in heating operations between connecting tube and coolant distributor
Have connection, therefore, do not influence the heating performance of system, when carrying out defrosting process, connect with connecting tube due to cooling liquid tube group and
Coolant distributor is connected to by separating tube simultaneously, thus the refrigerant in cooling liquid tube group can by separating tube and connecting tube and meanwhile into
Row flowing, increases the flow in the refrigerant unit time, reduces the resistance of refrigerant flowing, quickly melts to reach cooling liquid tube group
The effect of frost.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
With reference to Fig. 1, a kind of air-source heat exchanger system, including coolant distributor 1, heat exchanger body are present embodiments provided
2 and defrosting for improving 4 defrosting efficiency of cooling liquid tube group bypass tooling 3, heat exchanger body 2 is equipped with cooling liquid tube group 4, cooling liquid tube group
4 are connected to coolant distributor 2 by separating tube, and it includes check valve 31 and connecting tube 32 that defrosting, which bypasses tooling 3, and check valve 31 goes out liquid
Mouth one end is connected to the inlet of coolant distributor 1, and 31 one end of check valve is connected to cooling liquid tube group 4 by connecting tube 32.This hair
Bright structure is simple, in heating operations, due to the effect of check valve 31, is not connected between connecting tube 32 and coolant distributor 1,
Therefore, the heating performance for not influencing system, when carrying out defrosting process, since cooling liquid tube group 4 is connect and simultaneously with connecting tube 32
