In order to facilitate the understanding of the technical solutions of the present invention, prior to the detailed description, the existing defrosting methods are first described.

There are two existing defrosting methods, one is air conditioner defrosting. When the defrosting condition is reached, the indoor fan and the outdoor fan are stopped, the four-way valve is reversed, and the high-temperature refrigerant discharged from the compressor flows into the outdoor condenser, thereby Release heat and melt the frost layer on the surface of the condenser.

Another defrosting method is to introduce a heat storage module. The heat storage module is generally installed in parallel with the indoor unit. When the air conditioning system is running for heating, a part of the high-temperature refrigerant flows into the heat storage module and releases heat. The released heat is absorbed by the heat storage module. The heat storage medium is absorbed and stored. When the air conditioner operates in the defrosting mode, the throttling device of the indoor unit can be controlled, so that most of the low-temperature refrigerant after the condenser is released and defrosted flows into the thermal storage module, and absorbs the heat stored by the thermal storage medium in the thermal storage module. Conservation of heat is formed to achieve the purpose of defrosting operation cycle.

Although the introduction of the thermal storage module reduces the defrosting time to a certain extent, reduces indoor temperature fluctuations, and improves comfort, there is no essential difference in the process between the thermal storage module defrosting and the air conditioner defrosting, and the indoor fan needs to be stopped. The four-way valve also needs to be reversed. The high-temperature refrigerant discharged from the compressor flows into the outdoor condenser, and the low-temperature refrigerant obtained by heat exchange will still flow into the indoor side, causing the indoor temperature to drop instead of rising, and it cannot be continuously heated, thus affecting the comfort.

Therefore, it is necessary to provide an air-conditioning system that can prevent the indoor temperature from dropping during the defrosting process and improve comfort.

FIG. 1 shows a schematic structural diagram of an air conditioning system in an embodiment of the present application. For the convenience of description, the accompanying drawings only show the structures related to the embodiments of the present invention.

Referring to the drawings, an embodiment of the present application provides an air conditioning system 100 including a first compressor 10 , a second compressor 20 , a selector valve 30 , a heating heat exchanger 40 , a cooling heat exchanger 50 and a heat storage module 60 . In the embodiment of the present application, the heating heat exchanger 40 belongs to the indoor unit of the air conditioning system 100 , and the cooling heat exchanger 50 belongs to the outdoor unit of the air conditioning system 100 .

The first compressor 10 , the selector valve 30 , the heating heat exchanger 40 , the refrigeration heat exchanger 50 , the selector valve 30 and the first compressor 10 are connected in sequence to form a first circulation loop 65 . Specifically, the selector valve 30 is a four-way valve.

Specifically, referring to the direction of the solid line arrow in FIG. 1 , the first circulation loop 65 includes a heating mode and a cooling mode. When the first circulation loop 65 is in the heating mode, the refrigerant provided by the discharge end of the first compressor 10 passes through After selecting the valve 30 , it goes through the heating heat exchanger 40 and the refrigerating heat exchanger 50 in sequence, and then returns to the selection valve 30 and then enters the suction end of the first compressor 10 , thereby completing a heating cycle.

Referring to the direction of the dashed arrow in FIG. 1 , when the first circulation loop 65 is in the cooling mode, the refrigerant provided by the exhaust end of the first compressor 10 passes through the selection valve 30 and then passes through the cooling heat exchanger 50 and the heating heat exchanger in sequence. 40 returns to the selector valve 30 and then enters the suction end of the first compressor 10, thereby completing a refrigeration cycle.

The second compressor 20 , the refrigerating heat exchanger 50 , the heat storage module 60 and the second compressor 20 are connected in sequence to form a second circulation loop 70 which is provided independently from the first circulation loop 65 . The second compressor 20 can provide a refrigerant that can exchange heat with the refrigeration heat exchanger 50 , and the heat storage module 60 is provided with a heat storage medium that can exchange heat with the refrigerant.

It should also be pointed out that the second circulation loop 70 and the first circulation loop 65 are provided independently, which means that the piping systems and refrigerant flow paths of the second circulation loop 70 and the first circulation loop 65 are not related. The second circulation loop 70 may be opened only when the surface of the refrigeration heat exchanger 50 is frosted to a certain extent.

In this way, by being arranged in the second circulation circuit 70, when the refrigeration heat exchanger 50 needs to be defrosted, the second compressor 20 can be controlled to start up, and the second compressor 20 can perform work to discharge high-temperature refrigerant at the exhaust end. The high-temperature refrigerant further exchanges heat with the refrigerating heat exchanger 50 to defrost the frost layer of the refrigerating heat exchanger 50, and the refrigerant after releasing heat enters the heat storage module 60 and absorbs the heat storage medium in the heat storage module 60. The heat, to complete the conversion from liquid to gas, is returned to the suction end of the second compressor 20 to complete the defrost cycle. In the air conditioning system 100 of the present application, since the operation of the second circulation loop 70 is independent of the first circulation loop 65, it is not necessary to stop the indoor fan, and the four-way valve does not need to be reversed, so the low-temperature refrigerant will not flow into the indoor side , that is, at the heating heat exchanger 40, the high-temperature refrigerant always flows into the indoor side, so that continuous heating can be realized and the comfort of the air conditioner is improved.

Specifically, in the embodiment of the present application, the refrigerating heat exchanger 50 has a first pipeline and a second pipeline arranged independently of each other, and both ends of the first pipeline are respectively connected to the selector valve 30 and the heating heat exchanger 40 , Both ends of the second pipeline are communicated with the second compressor 20 and the heat storage module 30 respectively. That is, the first pipeline communicates with the first circulation loop 65 , and the second pipeline communicates with the second circulation loop 70 . By arranging two independent loops, it can be ensured that the first circulation loop 65 and the second circulation loop 70 are independent of each other and do not affect each other.

Further, the refrigeration heat exchanger 50 has a first heat exchange element, and the first pipe and the second pipe share the first heat exchange element. Specifically, the first heat exchange member is a fin, and in other embodiments, it may also be another component with heat exchange function, which is not limited herein. When the refrigeration heat exchanger 50 is frosted, the frost will condense on the surface of the first heat exchange element. When defrosting is required, the heat of the high-temperature defrosting refrigerant in the second circulation circuit 70 is conducted to the refrigeration heat exchanger through the second pipeline. 50 of the first heat exchange element, because the first heat exchange element is a common integrated structure of two circuits, the heat will be conducted from the high temperature area of the first heat exchange element to the low temperature area, so as to ensure the low temperature of the first heat exchange element.

In other embodiments, the first arrangement area and the second arrangement area are arranged staggered with each other. In this way, all parts of the first heat exchange element can be heated evenly, which is beneficial to defrosting.

In some embodiments, the second compressor 20 is an inverter compressor. In this way, the actual output power of the second compressor 20 can be controlled, and the amount of defrosting heat of the refrigeration heat exchanger 50 can be controlled. In addition, the operation output power of the second compressor 20 can be controlled and adjusted according to the frosting degree of the cooling and heat exchange device 50 in cooperation with the operation control logic of the whole machine. Specifically, when the refrigeration heat exchanger 50 has no tendency to frost or the degree of frost formation is very slight, the operating output power of the second compressor 20 is close to zero. Gradually increase the operating output power of the second compressor 20 to reduce the frosting severity of the refrigeration heat exchanger 50, so that under reasonable control logic and parameter control, the first circulation loop 65 can be operated in the heating mode. No shutdown due to defrosting, that is, to achieve uninterrupted continuous heating of the indoor unit, which greatly improves the comfort of the air conditioner.

Specifically, when the first circulation loop 65 is in the heating mode, a part of the high-temperature refrigerant will be distributed to the heat storage branch 75 , and the high-temperature refrigerant will release heat in the heat storage module 60 to be absorbed by the heat storage medium of the heat storage module 60 . Absorbed and stored, the refrigerant after heat release is reintroduced into the first circulation loop 65 to complete the heat storage function. In this way, the heat of the refrigerant in the heating mode of the first circulation loop 65 can be absorbed by arranging the heat storage branch 75, and no other external equipment is required to store heat for the heat storage module 65. Therefore, the operation of the heating cycle is not disturbed and the heat is simplified. The structure of the air conditioning system 100 is shown.

In addition, compared to the end of the heating heat exchanger 40 that is connected in parallel with the heat storage branch 75 away from the selector valve 30 and the cooling heat exchanger 50, this method can be simplified. Pipeline settings.

Specifically, the heat storage module 60 has a third pipeline and a fourth pipeline that are independent of each other. Both ends of the third pipeline are communicated with the refrigeration heat exchanger 50 and the second compressor 20 respectively, and both ends of the fourth pipeline are connected to each other. They are respectively communicated with the selector valve 30 and the refrigeration heat exchanger 50 . Further, the heat storage module 60 has a second heat exchange member storing a heat storage medium, and the third pipeline and the fourth pipeline share the second heat exchange member.

Further, the thermal storage branch 75 is provided with a thermal storage throttling device 80, and the thermal storage throttling device 80 is controlled to be turned on when the first circulation loop 65 is in the heating mode, so that the thermal storage branch 75 and the first circulating circuit 65 are opened. The circuit 65 is turned on, and the thermal storage throttling device 80 is controlled to be closed when the first circulation circuit 65 is in the cooling mode, so that the thermal storage branch 75 is disconnected from the first circulation circuit 65 . In this way, when the first circulation circuit 65 is in the cooling mode, the heat storage branch 75 does not participate in the circulation of the first circulation circuit 65, so as to prevent the heat storage medium from being cooled by the refrigerant.

It should also be pointed out that the form and type of the heat storage medium are not limited, and the substances that can achieve heat exchange, store heat, and complete the transfer of heat in the first circulation loop 65 and the second circulation loop 70 are all in the present invention.
