[0029] The cooling water circulation system 10 of the embodiments of the present application is described below with reference to the accompanying drawings.

[0030] As Figures 1-3 shown, the cooling water circulating system 10 of the air conditioning unit 20 in the embodiment of the present application comprises: a cooling water circulating loop 100, a blowdown pipeline 200 and an ultrasonic generator 300.

[0031] The cooling water circulating loop 100 comprises a condenser 110, and the cooling water outlet 112 of the condenser 110 is directly or indirectly connected to the water outlet pipeline 170. The water in the cooling water circulating loop 100 circulates and exchanges heat with the refrigerant in the condenser 110 after entering the condenser 110. Since the hardness ions such as calcium and magnesium in the cooling water will gradually form calcium carbonate, magnesium hydroxide and calcium sulfate in the condenser 110, and form scale in the condenser 110.

[0032] The ultrasonic generator 300 is configured to emit ultrasonic waves into the condenser 110, and use the ultrasonic waves to gradually loosen the scale attached to the condenser 110 from the condenser 110, so that the loosened scale is mixed in the water in the condenser 110, and the scale follows the water flow to the cooling water outlet 112. Among them, the ultrasonic generator 300 can be arranged on the condenser 110; or the ultrasonic generator 300 can also be arranged at other positions in the cooling water circulating system 10 which can emit ultrasonic waves into the condenser 110.

[0033] The inlet of the blowdown pipeline 200 is also directly or indirectly connected to the cooling water outlet 112 of the condenser 110, and the outlet of the blowdown pipeline 200 is in communication with the outside, so that the water mixed with scale in the condenser 110 can enter the blowdown pipeline 200 through the cooling water outlet 112, so that the water mixed with scale is discharged from the cooling water circulating loop 100 through the blowdown pipeline 200.

[0034] The blowdown pipeline is controlled to be opened and closed, and / or the water outlet pipeline 170 is controlled to be opened and closed, and / or the blowdown pipeline and the water outlet pipeline 170 are selectively communicated to the cooling water outlet 112 of the condenser 110, so as to make at least one of the blowdown pipeline and the water outlet pipeline 170 communicate with the cooling water outlet 112 of the condenser 110. That is, at least one of the blowdown pipeline and the water outlet pipeline 170 is controlled to be opened and closed; or the blowdown pipeline and the water outlet pipeline 170 are switchably communicated with the cooling water outlet 112. Further, the water and / or scale in the condenser 110 enters the blowdown pipeline and the water outlet pipeline 170 through the cooling water outlet 112.

[0035] The working process of the cooling water circulating system 10 in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0036] When the cooling water circulation system 10 is in normal operation, the water outlet pipeline 170 is connected with the cooling water outlet 112, and the blowdown pipeline is disconnected from the cooling water outlet 112. Further, only the water outlet pipeline 170 is connected with the cooling water outlet 112, so that the water is circulated in the cooling water circulation loop 100, and exchanges heat with the refrigerant in the condenser 110 after the water enters the condenser 110.

[0037] When it is necessary to clean the condenser 110, the water outlet pipeline 170 is disconnected from the cooling water outlet 112, and the blowdown pipeline is connected with the cooling water outlet 112. The ultrasonic generator 300 is controlled to emit ultrasonic waves into the condenser 110, and water is simultaneously introduced into the condenser 110. The water scale impacted by the ultrasonic waves falls off and enters the water in the condenser 110, and is discharged to the outside through the blowdown pipeline along with the water.

[0038] Compared with the related art, the cooling water circulation system 10 of the embodiment of the present application has the cooling water circulation loop 100, the cooling water circulation loop 100 has the ultrasonic generator 300 for emitting ultrasonic waves to the condenser 110 thereof, and the cooling water outlet 112 of the condenser 110 of the cooling water circulation loop 100 is directly or indirectly connected with the blowdown pipeline 200 capable of discharging water and / or water scale. When it is necessary to clean the water scale in the condenser 110, it is only necessary to emit ultrasonic waves by the ultrasonic generator 300 to make the water scale in the condenser 110 fall off, and to connect the blowdown pipeline 200 with the cooling water outlet 112 of the condenser 110, so that the water scale can be cleaned out of the condenser 110. It is not necessary to dismount the condenser 110 from the air conditioning unit 20 and to mount the condenser 110 back, and the cumbersome dismounting process of the condenser 110 is omitted, so that the cleaning efficiency of the condenser 110 is greatly improved, and the use experience of the user is improved.

[0039] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The cooling water circulation system 10 of the embodiment of the present application further comprises a first on-off valve 141 and a second on-off valve 142. The first on-off valve 141 is arranged on the water outlet pipeline, and the second on-off valve 142 is arranged on the blowdown pipeline 200.

[0040] When the cooling water circulation system 10 is in normal operation, the first switch valve 141 is controlled to be open, so that the water outlet line 170 is connected with the cooling water outlet 112, and only the water outlet line 170 is connected with the cooling water outlet 112, so that the water is circulated in the cooling water circulation loop 100. When the condenser 110 needs to be cleaned, the first switch valve 141 is controlled to be closed, so that the water outlet line 170 is disconnected with the cooling water outlet 112, and the second switch valve 142 is controlled to be open, so that the blowdown line is connected with the cooling water outlet 112. Thus, the water and / or scale is discharged to the outside through the blowdown line.

[0041] That is, by arranging the first switch valve 141 and the second switch valve 142 on the water outlet line and the blowdown line 200 respectively, the first switch valve 141 and the second switch valve 142 are used to control the opening and closing of the water outlet line and the blowdown line 200, which is not only convenient to operate, but also simple in structure.

[0042] In some embodiments of the utility model, the cooling water circulation system 10 further comprises a three-way valve, and the three-way valve comprises an inlet and two outlets. The inlet of the three-way valve is connected with the cooling water outlet 112, and the two outlets of the three-way valve are connected with the inlet of the water outlet line and the inlet of the blowdown line 200 respectively.

[0043] When the cooling water circulation system 10 is in normal operation, the inlet of the three-way valve is controlled to be connected with the outlet connected with the water outlet line 170, so that the water outlet line 170 is connected with the cooling water outlet 112, and only the water outlet line 170 is connected with the cooling water outlet 112, so that the water is circulated in the cooling water circulation loop 100. When the condenser 110 needs to be cleaned, the inlet of the three-way valve is controlled to be connected with the outlet connected with the inlet of the blowdown line 200, so that only the blowdown line is connected with the cooling water outlet 112.

[0044] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 the cooling water circulation system 10 further comprises a water supplement line 150. The water supplement line 150 is used to supplement water to the condenser 110, and one end of the water supplement line 150 is connected with the cooling water inlet 111 of the condenser 110, and the other end of the water supplement line 150 is connected with a water source outside.

[0045] It can be understood that, after the scale is discharged to the outside by the blowdown pipeline following the water, the water amount circulating in the cooling water circulation loop 100 for heat exchange is reduced, which will affect the heat exchange effect. The water supplement pipeline 150 connected with the external water source is connected to the cooling water inlet 111 of the condenser 110. After the water flow in the cooling water circulation loop 100 is lost, the water supplement pipeline 150 can supplement water to the cooling water circulation loop 100 in time, thereby ensuring the heat exchange effect.

[0046] The third switch valve 143 is arranged on the water supplement pipeline 150, so that the opening and closing of the water supplement pipeline 150 is controlled through the third switch valve 143, which not only facilitates the control of the opening and closing of the water supplement pipeline 150, but also has a simple structure.

[0047] Further, as shown in Figure 1 and Figure 2 , the cooling water circulation loop 100 also has a water inlet pipeline 160 connected with the cooling water inlet 111, and the fourth switch valve 144 is arranged on the water inlet pipeline 160.

[0048] When the cooling water circulation system 10 is normally working, the third switch valve 143 is controlled to be disconnected, and the fourth switch valve 144 is controlled to be connected, so that only the water in the cooling water circulation loop 100 enters the condenser 110 to perform heat exchange.

[0049] When the condenser 110 needs to be cleaned, the third switch valve 143 is controlled to be connected, so that the water supplement pipeline 150 supplements water to the cooling water circulation loop 100. The fourth switch valve 144 can be controlled to be disconnected, that is, only the water in the condenser 110 is consumed to flush the scale in the condenser 110 out of the blowdown pipeline; or the fourth switch valve 144 can be controlled to be connected.

[0050] In some embodiments of the present application, as shown in Figure 1 and Figure 2 , the condenser 110 further comprises a shell 113 and a plurality of heat exchange pipes 115. The shell 113 is provided with a cooling water inlet 111; the shell 113 defines a converging chamber 114 in communication with the cooling water outlet 112. The plurality of heat exchange pipes 115 are arranged in the shell 113, and the water inlet end of each heat exchange pipe 115 is in communication with the cooling water inlet 111, and the water outlet end of each heat exchange pipe 115 is in communication with the converging chamber 114. Thus, through the converging chamber 114, the water and / or scale discharged from the plurality of heat exchange pipes 115 is first collected in the converging chamber 114, and then discharged through the cooling water outlet 112.

[0051] Further, the shell 113 further defines a distribution chamber 116, which is in communication with the cooling water inlet 111; the inlet ends of the plurality of heat exchange pipes 115 are in communication with the distribution chamber 116. Thus, water can uniformly enter each heat exchange pipe 115, so that the water can flush the scale in each heat exchange pipe 115 into the collecting chamber 114, thereby ensuring the cleaning effect.

[0052] In some embodiments of the present application, as shown in Figure 1 and Figure 2 , the ultrasonic generator 300 comprises at least one sound wave emitting part 310, which is correspondingly arranged in the distribution chamber 116 and / or the collecting chamber 114. That is, the sound wave emitting part 310 is one, which is arranged in the distribution chamber 116; or the sound wave emitting part 310 is one, which is arranged in the collecting chamber 114; or the sound wave emitting part 310 is two, which are arranged in the collecting chamber 114 and the distribution chamber 116, respectively. Directly arranging the sound wave emitting part 310 inside the condenser 110 reduces the energy loss of the ultrasonic wave during propagation, thereby further improving the cleaning effect of the ultrasonic wave on the scale in the condenser 110.

[0053] Specifically, in the case where the sound wave emitting part 310 is arranged in the distribution chamber 116, the sound wave emitting part 310 is arranged towards the water inlet end; and / or, in the case where the sound wave emitting part 310 is arranged in the collecting chamber 114, the sound wave emitting part 310 is arranged towards the water outlet end. That is, the sound wave emitting part 310 is arranged towards the opening position of the heat exchange pipe 115, thereby reducing the energy loss of the emitted ultrasonic wave passing through the heat exchange pipe 115, and further improving the cleaning effect of the ultrasonic wave on the scale in the condenser 110.

[0054] Optionally, the ultrasonic generator 300 comprises an ultrasonic wave emitting body and an excitation controller, wherein the ultrasonic wave emitting body forms the sound wave emitting part 310.

[0055] In some optional embodiments of the present application, as shown in Figure 1 , the distribution chamber 116 and the collecting chamber 114 are arranged in the upper and lower directions, and the distribution chamber 116 is located above the collecting chamber 114. The heat exchange pipe 115 is in the shape of a coil pipe, comprising a water inlet section and a water outlet section arranged in parallel, and a transition section connected between the water inlet section and the water outlet section. The inlet of the water inlet section of each heat exchange pipe 115 is in communication with the distribution chamber 116, and the outlet of the water inlet section is connected with the inlet of the transition section. The outlet of the transition section is connected with the inlet of the water outlet section, and the outlet of the water outlet section is in communication with the collecting chamber 114.

[0056] In some optional embodiments of the present application, as shown in Figure 1As shown, the distribution chamber 116 and the collection chamber 114 are arranged in the left-right direction with a spacing, and the distribution chamber 116 is located on the left side of the collection chamber 114. The heat exchange pipe 115 is in a straight pipe shape, and the two ends of each heat exchange pipe 115 in the left-right direction are respectively communicated with the distribution chamber 116 and the collection chamber 114.

[0057] Further, as shown, Figure 1 Figure 1 The condenser 110 further comprises a liquid level detector 400 arranged on the top wall 117 of the distribution chamber 116 to detect the water level of the water in the condenser 110.

[0058] When it is necessary to clean the condenser 110, the first switch valve 141 and the fourth switch valve 144 are closed, and then the second switch valve 142 is opened to drain the remaining water in the condenser 110. When the water level in the condenser 110 is detected by the liquid level detector 400, and the water level is lower than the first preset value, for example, the water level is lower than 5%, the second switch valve 142 is closed, and the third switch valve 143 is opened to replenish water into the condenser 110. When the water level is higher than the second preset value, for example, higher than 95%, the third switch valve 143 is closed. The ultrasonic generator 300 is turned on. The second switch valve 142 is opened, and the scale is drained through the blowdown line. When the scale is drained, the second switch valve 142 is closed.

[0059] The air conditioning unit 20 of the embodiment of the utility model comprises the cooling water circulating system 10 of any one of the above embodiments.

[0060] The air conditioning unit 20 of the embodiment of the utility model, the cooling water circulating system 10 has the cooling water circulating loop 100, the cooling water circulating loop 100 has the ultrasonic generator 300 that emits ultrasonic wave to its condenser 110, and the cooling water outlet 112 of the condenser 110 of the cooling water circulating loop 100 is directly or indirectly connected with the blowdown line 200 capable of draining water and / or scale. When it is necessary to clean the scale in the condenser 110, only the ultrasonic generator 300 is used to emit ultrasonic wave to make the scale in the condenser water fall off, and the blowdown line 200 is communicated with the cooling water outlet 112 of the condenser 110, so that the scale in the condenser 110 can be cleaned out. The condenser 110 does not need to be disassembled from the air conditioning unit 20 and assembled back, and the cumbersome disassembly process of the condenser 110 is saved, so that the cleaning efficiency of the condenser 110 is greatly improved, and the use experience of the user is improved.
