Referring to fig. 1, the present application provides an inverter air conditioning system 100, wherein the inverter air conditioning system 100 controls a frequency during operation through an inverter (not shown).
The air conditioner frequency converter mainly dissipates heat through the liquid cooling radiator, the existing liquid cooling radiator is connected to a heat exchange circulating path of an air conditioning system, and the cooling temperature control of the air conditioner frequency converter is realized through a refrigerant in the heat exchange circulating path. However, the use of the refrigerant at the liquid cooling radiator causes the temperature of the refrigerant in the air conditioning system to rise, so that the refrigerating capacity of the air conditioner is reduced, and the refrigerating performance of the air conditioning system is affected.
Referring to fig. 1, the present application provides an inverter air conditioning system 100, where the inverter air conditioning system 100 includes a heat exchange circulation path 10, a refrigerant flow path 20, and a main water path 30.
The heat exchange circulation path 10 includes a first heat exchanger 11, a throttle valve 12 having a first circulation port 121, a first valve 13, and a second heat exchanger 14 having a second circulation port 141, which are sequentially provided in series. The heat exchange circulation path 10 further includes a compressor 15 and a switching valve (not shown), and the compressor 15 is connected to the first heat exchanger 11 and the second heat exchanger 14 through the switching valve. The heat exchange circulation path 10 is filled with a refrigerant and exchanges heat with the outside.
The refrigerant flow path 20 is communicated with the heat exchange circulation path 10; the cooling medium flow path 20 includes an inlet 21 and an outlet 22, the inlet 21 is located between the first circulation port 121 and the first valve 13, the outlet 22 is located between the first valve 13 and the second circulation port 141, and the cooling medium flow path 20 further includes a liquid cooling radiator 23 connected in parallel with the first valve 13. When the refrigerant flow path 20 is in operation, the refrigerant in the heat exchange circulation path 10 can flow into the refrigerant flow path 20, and is used for cooling the inverter through the liquid cooling radiator 23.
The main water passage 30 is connected to the first heat exchanger 11 and communicates with an inlet of the liquid-cooled radiator 23. The main water path 30 is internally circulated with cooling water, and when the main water path 30 operates, the cooling water in the main water path 30 can flow into the liquid cooling radiator 23 for cooling the frequency converter.
When the variable frequency air conditioning system 100 is in the first state, the heat exchange circulation path 10 and the main water path 30 operate, the refrigerant flow path 20 is closed, and the condensed water of the first heat exchanger 11 can enter the liquid cooling radiator 23 through the main water path 30. That is, in the first state, the liquid-cooled radiator 23 is cooled by water cooling.
When the inverter air conditioning system 100 is in the second state, the heat exchange circulation path 10 and the main water path 30 operate, the refrigerant flow path 20 is closed, and the cooling water in the main water path 30 can enter the liquid cooling radiator 23. That is, in the second state, the liquid-cooled radiator 23 is cooled by water cooling.
When the inverter air conditioning system 100 is in the third state, the heat exchange circulation path 10 and the refrigerant flow path 20 operate, the first valve 13 and the main water path 30 are closed, and the refrigerant in the heat exchange circulation path 10 can enter the refrigerant flow path 20, and enters the heat exchange circulation path 10 from the refrigerant flow path 20 after being acted by the liquid cooling radiator 23. In the third state, the liquid-cooled heat sink 23 is cooled by the refrigerant.
When the inverter air conditioning system 100 is in the fourth state, the heat exchange circulation path 10 is operated, and the refrigerant flow path 20 and the main water path 30 are closed. That is, in the fourth state, the liquid-cooled radiator 23 relies on natural cooling.
The first state is a cooling state of the inverter air conditioning system 100, and when the inverter air conditioning system 100 cools, the first heat exchanger 11 functions as an evaporator and is capable of generating condensed water. The second state is a high-frequency heating state of the inverter air-conditioning system 100, the third state is a medium-frequency heating state of the inverter air-conditioning system 100, and the fourth state is a low-frequency heating state of the inverter air-conditioning system 100, and when the inverter air-conditioning system 100 heats, the first heat exchanger 11 is used as a condenser, and no condensed water is generated.
It should be noted that, in this embodiment, the high frequency state of the inverter air conditioning system 100 is greater than 80HZ, the intermediate frequency state of the inverter air conditioning system 100 is 40HZ to 80HZ, and the low frequency state of the inverter air conditioning system 100 is less than 40HZ. Of course, in other embodiments, the high frequency, the intermediate frequency, and the low frequency of the inverter air conditioning system 100 may be further divided according to the actual operation condition of the air conditioner, for example, the high frequency of the inverter air conditioning system 100 may be greater than 90HZ, the intermediate frequency of the inverter air conditioning system 100 may be 50HZ to 90HZ, and the low frequency of the inverter air conditioning system 100 may be less than 50 HZ.
The application provides an inverter air conditioning system 100 forms an independent water-cooling route through setting up main water route 30 and refrigerant flow path 20 to can make liquid cooling radiator 23 not inject the refrigerant under the refrigeration state, can not cause the rising of refrigerant temperature, eliminate under the refrigeration mode among traditional inverter air conditioning system liquid cooling radiator to inverter air conditioning system's influence, thereby the whole refrigerating output that has improved inverter air conditioning system 100 in other words. Meanwhile, the condensate water formed in the refrigeration state has rich cold energy, and when the condensate water is used for the liquid cooling radiator 23, a better cooling effect can be achieved.
Under the high-frequency heating state, the frequency converter runs fully, more heat can be generated, the performance of cooling water is superior to that of a refrigerant, the cooling effect of the liquid cooling radiator 23 can be enhanced by adopting the cooling water as a cooling medium, the temperature controllability of the frequency converter is enhanced, and the reliability of the frequency converter is enhanced.
In the intermediate-frequency heating state, the heat generated by the frequency converter is reduced, and at the moment, the liquid cooling radiator 23 is communicated into the heat exchange circulation path 10, so that the good heat exchange effect can be realized by the refrigerant in the heat exchange circulation path 10. At this time, the water cooling path can be closed, thereby reducing the power consumption of the inverter air conditioning system 100.
In the low-frequency heating state, if the heat dissipation requirement of the inverter is not high, the liquid-cooled radiator 23 is naturally cooled without cooling by cooling water or a refrigerant, thereby further reducing the energy consumption of the inverter air conditioning system 100.
Because the cooling water circulation path and the refrigerant circulation path are relatively independent, the risk resistance of the frequency converter during cooling can be improved. When the cooling water is cooled, the cooling medium can be switched to cool; when the cooling of the refrigerant has a problem, the cooling water can be switched to cool. Therefore, the accuracy and the reliability of the frequency converter during cooling are enhanced, and reasonable configuration and use of energy sources can be realized.
Meanwhile, the inverter air conditioning system 100 provided by the present application can utilize condensed water generated during refrigeration. Because the condensed water is recycled, the problem that the condensed water in the traditional variable frequency air conditioning system is randomly discharged is solved, the condensed water is changed into valuables, and the energy utilization rate and the environmental protection performance of the variable frequency air conditioning system 100 are improved.
Referring to fig. 1, the main waterway 30 includes a reservoir 31, a first branch 32, a second branch 33 and a third branch 34. Two ends of the first branch 32 are respectively communicated with the first heat exchanger 11 and the liquid storage tank 31. The two ends of the second branch 33 are respectively communicated with the liquid storage tank 31 and the inlet of the liquid cooling radiator 23. The third branch 34 is communicated with the reservoir 31, and the third branch 34 is used for supplying the reservoir 31 with cooling water. When the variable frequency air conditioning system 100 is in the first state, the condensed water of the first heat exchanger 11 flows into the reservoir 31 through the first branch 32, the cooling water of the third branch 34 flows into the reservoir 31, and the cooling water in the reservoir 31 flows into the liquid-cooled radiator 23 through the second branch 33. When the variable frequency air conditioning system 100 is in the second state, the cooling water in the third branch 34 flows into the liquid storage tank 31, and the cooling water in the liquid storage tank 31 flows into the liquid cooling radiator 23 through the second branch 33.
Specifically, the main water passage 30 functions to supply the liquid-cooled radiator 23 with cooling water. The first branch line 32 mainly collects, transfers, and stores the condensate water generated in the first heat exchanger 11 in the cooling state in the reservoir tank 31. The third branch 34 supplements the cooling water in the liquid storage tank 31 to ensure that the liquid in the liquid storage tank 31 is sufficient to satisfy the consumption of the liquid cooling radiator 23. The second branch line 33 communicates with the liquid-cooled radiator 23 and supplies the liquid-cooled radiator 23 with the cooling water in the reservoir tank 31.
Further, since the first heat exchanger 11 only generates condensed water in the cooling state, the condensed water and the cooling water supplemented by the third branch 34 are mainly in the reservoir 31. In the heating state, the cooling water in the reservoir 31 is mainly supplemented to the third branch 34. For convenience of description, the liquid obtained by mixing the condensed water with the cooling water supplemented by the third branch 34 is collectively referred to as cooling water in the present application.
Referring to fig. 1, the second branch 33 includes a second valve 331, and the second valve 331 is located between the liquid storage tank 31 and the liquid-cooled heat sink 23. When the variable frequency air conditioning system 100 is in the first state or the second state, both the first valve 13 and the second valve 331 are opened. When the variable frequency air conditioning system 100 is in the third state, both the first valve 13 and the second valve 331 are closed. When the variable frequency air conditioning system 100 is in the fourth state, the first valve 13 is opened, and the second valve 331 is closed.
Specifically, the second valve 331 can control the opening or closing of the second branch 33. When the inverter air-conditioning system 100 is in a cooling state or a high-frequency heating state, the second valve 331 controls the second branch 33 to open, and the liquid-cooling radiator 23 exchanges heat with the inverter through the cooling water conveyed by the second branch 33. When the inverter air conditioning system 100 is in the intermediate-frequency heating state, the second valve 331 controls the second branch 33 to close, so as to prevent the cooling water in the liquid storage tank 31 from entering the liquid cooling radiator 23 and mixing with the refrigerant. When the variable frequency air conditioning system 100 is in the low frequency heating state, the second valve 331 controls the second branch 33 to close, and the liquid cooling radiator 23 cools naturally, thereby reducing energy consumption.
The third branch 34 includes a water reservoir 341 and a first water pump 342. The first water pump 342 is disposed between the reservoir 341 and the reservoir 31, and the first water pump 342 is capable of pumping the cooling water in the reservoir 341 into the reservoir 31.
The third branch 34 is used for replenishing the cooling water in the reservoir 31. Specifically, the cooling water in the reservoir 341 is mainly supplemented by the ground water, and the cooling water in the reservoir 341 is pumped into the reservoir 31 by the first water pump 342 to supplement the cooling water in the reservoir 31.
Referring to fig. 1, the refrigerant flow path 20 further includes: a third valve 24 and a fourth valve 25. The third valve 24 is located between the first circulation port 121 and the inlet of the liquid cooling radiator 23; the fourth valve 25 is located between the second flow port 141 and the inlet of the liquid-cooled heat sink 23. When the variable frequency air conditioning system 100 is in the first state or the second state, both the third valve 24 and the fourth valve 25 are closed. When the variable frequency air conditioning system 100 is in the third state, both the third valve 24 and the fourth valve 25 are opened. When the variable frequency air conditioning system 100 is in the fourth state, both the third valve 24 and the fourth valve 25 are closed.
Specifically, the third valve 24 and the fourth valve 25 cooperate to open or close the refrigerant flow path 20. When the inverter air conditioning system 100 is in a cooling state or a high-frequency heating state, the third valve 24 and the fourth valve 25 control the refrigerant flow path 20 to be closed, so as to prevent the refrigerant of the heat exchange circulation path 10 from flowing into the refrigerant flow path 20, which causes waste of the refrigerant. When the inverter air conditioning system 100 is in the intermediate-frequency heating state, the third valve 24 and the fourth valve 25 control the opening of the refrigerant flow path 20, and the liquid cooling radiator 23 exchanges heat with the inverter through the refrigerant flowing into the refrigerant flow path 20 from the heat exchange circulation path 10. When the inverter air conditioning system 100 is in the low-frequency heating state, the third valve 24 and the fourth valve 25 control the refrigerant flow path 20 to be closed, and the liquid cooling radiator 23 naturally cools down, so that the loss of the refrigerant is reduced.
Further, the cooling medium flow path 20 includes a dry filter 26. The drier filter 26 is located between the fourth valve 25 and the outlet of the liquid-cooled radiator 23. By providing the dry filter 26, the residual moisture in the liquid cooling radiator 23 can be absorbed, and the moisture is prevented from being mixed into the refrigerant, thereby affecting the refrigeration performance of the variable frequency air conditioning system 100.
Referring to fig. 1, the inverter air conditioning system 100 further includes a collecting water path 40, and the collecting water path 40 is communicated with an outlet of the liquid cooling radiator 23. The collection water path 40 can collect the cooling water or the refrigerant flowing out through the outlet of the liquid-cooled radiator 23.
Specifically, the collecting water path 40 includes a fourth branch 41, the fourth branch 41 includes a waste liquid tank 411, and the waste liquid tank 411 is communicated with the outlet of the liquid-cooled radiator 23. When cooling water enters the liquid cooling radiator 23 for cooling, the cooling water introduced at the initial stage needs to flush and discharge the residual refrigerant or impurities in the liquid cooling radiator 23 into the waste liquid tank 411, so that the probability that the impurities enter the cooling water after heat exchange is reduced, and subsequent recycling is influenced.
Further, the collecting water path 40 further includes a fifth branch 42, the fifth branch 42 is communicated with the outlet of the liquid cooling radiator 23, the fifth branch 42 includes a filtering device 421, a sterilizing tank 422 and a water storage tank 423, and the cooling water flowing out of the liquid cooling radiator 23 can sequentially enter the filtering device 421, the sterilizing tank 422 and the water storage tank 423.
The cooling water flowing out of the liquid cooling radiator 23 can meet the daily use requirement through the treatment of the filtering device 421 and the disinfection tank 422. The fifth branch 42 further includes a second water pump 425, and the second water pump 425 can deliver the cooling water treated by the disinfection tank 422 to the water storage tank 423 for daily use. Thus, the resource utilization rate and the environmental protection performance of the variable frequency air conditioning system 100 are improved.
Further, the collecting water circuit 40 further includes a fifth valve 412 and a sixth valve 424. The fifth valve 412 is located on the fourth branch 41 and between the waste tank 411 and the outlet of the liquid-cooled radiator 23. A sixth valve 424 is located on the fifth branch 42 and between the filter 421 and the outlet of the liquid-cooled heat sink 23.
Specifically, the fifth valve 412 is used for opening or closing the fourth branch 41, and the sixth valve 424 is used for opening or closing the fifth branch 42. When the collecting water path 40 operates, the fifth valve 412 is first opened and the sixth valve 424 is closed, at this time, the fourth branch 41 is opened and the fifth branch 42 is closed, and the cooling water flushes the refrigerant or impurities remaining in the liquid-cooled radiator 23 and discharges the refrigerant or impurities to the waste liquid tank 411. Then, the sixth valve 424 is opened and the fifth valve 412 is closed, at this time, the fourth branch 41 is closed, the fifth branch 42 is opened, and the cooling water radiated by the liquid-cooled radiator 23 is processed and recycled in the fifth branch 42.
