Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

Referring to fig. 1-2, a first aspect of the present application provides a water recovery device 100, which can effectively cool a condenser 210 of an outdoor unit 200 (shown in fig. 3) to reduce energy consumption of the outdoor unit 200.

The water recovery device 100 is applied to an air conditioner outdoor unit 200, and the air conditioner outdoor unit 200 includes a condenser 210; the water recovery device 100 includes a water storage assembly 110, a spray branch 120, a spray water recovery branch 130, and a water supply branch 140; the water storage assembly 110 includes a water storage tank 111; the spraying branch 120 is communicated with the water storage tank 111, and the spraying branch 120 is used for spraying water to the condenser 210 so as to cool the condenser 210; the spray water recovery branch 130 is communicated with the water storage tank 111, and the spray water recovery branch 130 is at least used for recovering the water which is sprayed to the condenser 210 but not completely evaporated into the water storage tank 111; the water supply branch 140 is communicated with the water storage tank 111, the water supply branch 140 is used for accessing an external water source, and when the water level in the water storage tank 111 is smaller than a first preset water level L, water is supplied into the water storage tank 111 through the external water source.

The specific structure of the water recovery device 100 will be described below with reference to fig. 1-2.

As shown in fig. 1-2, the air conditioner outdoor unit 200 includes a Condenser 210 (condensing unit), the Condenser 210 is one of heat exchangers, and a high-temperature and high-pressure gaseous refrigerant is converted into a high-temperature and high-pressure liquid refrigerant after being discharged by the Condenser 210, and heat released by the Condenser 210 during operation is conducted to air near the pipe. And it will be appreciated that the condenser 210 operation is exothermic, so the condenser 210 surface temperature is generally high.

The water recovery device 100 includes a water storage assembly 110, a spray branch 120, a spray water recovery branch 130, and a water supply branch 140.

The water storage assembly 110 is capable of storing water, and the water storage assembly 110 includes a water storage tank 111. The water storage tank 111 is used as a water storage container, the specific shape of the water storage tank 111 is not limited, and a designer can reasonably design according to actual needs, for example, the shape of the water storage tank 111 can be, but is not limited to, cuboid or cylindrical, etc. The specific material of the water storage tank 111 is not limited, and a designer may reasonably select according to actual needs, for example, the material of the water storage tank 111 may be, but not limited to, plastic or metal. It should be noted that, since the water storage tank 111 is only used for storing water, when the water quality of the external water source connected to the water supply branch 140 is poor, the water storage tank 111 may be replaced by a water storage tank 111 having a water softening function, for example, an ion exchange resin or the like is provided in the water storage tank 111.

The spray branch 120 serves as a structural member for spraying water stored in the water storage tank 111 to the surface of the condenser 210 to cool the condenser 210, and a specific structure of the spray branch 120 will be described below.

The spraying branch 120 is communicated with the water storage tank 111, the spraying branch 120 is configured to spray water to the condenser 210 for heat exchange, that is, the water in the water storage tank 111 is sprayed to the surface of the condenser 210 through the spraying branch 120, and the water sprayed on the surface of the condenser 210 is evaporated to become water vapor through absorbing heat on the surface of the condenser 210, so that the temperature of the surface of the condenser 210 is reduced, and the heat exchange efficiency of the condenser 210 is improved.

The shower water recovery branch 130 serves as a structural member for recovering water sprayed to the condenser 210 but not completely evaporated into the water storage tank 111, and a specific structure of the shower water recovery branch 130 will be described below.

The spray water recovery branch 130 is communicated with the water storage tank 111, water in the water storage tank 111 is sprayed on the surface of the condenser 210 through the spray branch 120, a part of water absorbs heat on the surface of the condenser 210 and is completely evaporated to become water vapor, and the other part of water absorbs heat on the surface of the condenser 210 and is not completely evaporated or is in a liquid state, and returns to the water storage tank 111 again through the spray water recovery branch 130, so that the aim of recycling is fulfilled, and water resources can be saved to a certain extent. It should be noted that, in rainy days, rainwater may also flow into the water storage tank 111 through the shower water recovery branch 130 and be stored for the next shower use.

The water supply branch 140 is a structural member capable of supplying water to the water storage tank 111 in time when the water level in the water storage tank 111 is low, so as to ensure normal spraying, and the specific structure of the water supply branch 140 will be described below.

The water supply branch 140 is communicated with the water storage tank 111, and the water supply branch 140 is used for accessing an external water source, and when the water level in the water storage tank 111 is smaller than a first preset water level L, the external water source supplies water into the water storage tank 111 through the water supply branch 140. Wherein the "external water source" may be, but is not limited to, an engineering end pipe network or another water tank independent of the water storage tank 111. The "first preset water level L" is understood to mean that the water in the water storage tank 111 cannot be drawn out of the water storage tank 111 and sprayed to the water level corresponding to the condenser 210 under the action of the spraying branch 120, or that the water in the water storage tank 111 can be drawn out of the water storage tank 111 and sprayed to the water level corresponding to the condenser 210 under the action of the spraying branch 120 (but the drawn water contains part of air at this time, so that the spraying is insufficient); the specific value of the first preset water level L is not limited, and a designer can reasonably design according to actual needs.

Based on the water recovery device 100 in the embodiment of the application, by designing the spraying branch 120 and the water storage tank 111, the spraying branch 120 can spray the water in the water storage tank 111 to the surface of the condenser 210, and the water sprayed on the surface of the condenser 210 is evaporated into water vapor by absorbing the heat on the surface of the condenser 210, so that the temperature on the surface of the condenser 210 is reduced, thereby improving the heat exchange efficiency of the condenser 210 and reducing the temperature of the condenser 210; by designing the spray water recovery branch 130 and the water storage tank 111, the spray water recovery branch 130 can recover the water which is sprayed to the condenser 210 but not completely evaporated into the water storage tank 111 again, thereby achieving the aim of recycling and saving water resources to a certain extent; through design water supply branch road 140 and storage water tank 111, when the water level in storage water tank 111 is less than first preset water level L, outside water source can in time supply water to storage water tank 111 through water supply branch road 140 to guarantee that the water yield in storage water tank 111 is sufficient, in order to spray the use next time.

Further, as shown in fig. 1-2, considering that the spray water recovery branch 130 can recover the water sprayed to the surface of the condenser 210 but not completely evaporated to the structural component in the water storage tank 111, in order to make the spray water recovery branch 130 have a corresponding function, the spray water recovery branch 130 is designed to include a water receiving member of the condenser 210 and a first connecting pipe 132. The water receiving member of the condenser 210 is at least positioned at the bottom of the condenser 210 to at least receive water sprayed to the condenser 210 but not completely evaporated; the first end of the first connection pipe 132 communicates with the condenser 210 water receiving part, and the second end of the first connection pipe 132 communicates with the water storage tank 111.

The specific structure of the water receiving member of the condenser 210 is not limited herein, and a designer may reasonably design according to actual needs, for example, the water receiving member of the condenser 210 may be, but not limited to, a basin, a cylinder, a tray, etc. In the embodiment of the present application, the water receiving member of the condenser 210 has a tray structure. The specific connection mode between the first connection pipe 132 and the water receiving part of the condenser 210 and between the first connection pipe 132 and the water storage tank 111 is not limited, and a designer can reasonably design according to actual needs; for example, the first connection pipe 132 may be detachably connected to the water receiving part (the water storage tank 111) of the condenser 210 or may be non-detachably connected to the water receiving part; when the first connection pipe 132 is detachably connected to the water receiving part (the water storage tank 111) of the condenser 210, the first connection pipe 132 may be connected to the water receiving part (the water storage tank 111) of the condenser 210 by, but not limited to, screwing or clamping; when the first connection pipe 132 is non-detachably connected to the water receiving part (the water storage tank 111) of the condenser 210, the first connection pipe 132 may be connected to the water receiving part (the water storage tank 111) of the condenser 210 by, but not limited to, bonding, welding, or the like.

The water receiving member of the condenser 210 is at least arranged at the bottom of the condenser 210, so that at least the water sprayed to the surface of the condenser 210 but not completely evaporated drops into the water receiving member of the condenser 210 under the action of the gravity of the water, and the water dropped into the water receiving member of the condenser 210 returns to the water storage tank 111 again through the first connecting pipe 132, thereby achieving the purpose of recycling and saving water resources to a certain extent. In addition, in rainy days, rainwater falls into the water receiver of the condenser 210 and flows into the water storage tank 111 through the first connection pipe 132 and is stored for the next shower use.

Further, as shown in fig. 1-2, the shower water recovery branch 130 is designed to further include the first filter 133 in order to prevent the first connection pipe 132 from being clogged with impurities, considering that water dropped into the water receiving member of the condenser 210, which is in contact with the surface of the condenser 210 but is not completely evaporated, may be doped with impurities, or that rainwater dropped into the water receiving member of the condenser 210 may be doped with impurities. The first filter 133 is provided on at least one of the water receiving member of the condenser 210 and the first connection pipe 132.

In particular, it is contemplated that the specific embodiment of the first filter 133 may be numerous and that the specific connection of the first filter 133 to the water receiving member of the condenser 210 and/or the first connection tube 132 may be different for different embodiments, and that the specific embodiment of the first filter 133 may be, but is not limited to, one or more of the following embodiments.

In the first embodiment, the water receiving member of the condenser 210 has a drain hole, and the first filter member 133 includes a filter screen, which is disposed corresponding to the drain hole and is connected to a wall of the drain hole. Through the design filter screen, the filter screen can be with the impurity in the water that drops in condenser 210 water receiver with condenser 210 surface contact but not complete evaporation and will drop in the rainwater in the condenser 210 water receiver filter to effectively reduce the impurity and get into first connecting pipe 132 through the wash port and block up first connecting pipe 132's possibility.

In a second embodiment, the first filter 133 comprises a filter connected in series to the first connection tube 132. By designing the filter, the filter can effectively filter the water flowing into the first connection pipe 132 to ensure that the water flowing into the water storage tank 111 is clean water.

Further, as shown in fig. 1-2, considering that the water supply branch 140 is used as a structural member for supplying water to the water storage tank 111 in time when the water level in the water storage tank 111 is low, so as to ensure that spraying can be performed normally, in order to make the water supply branch 140 have a corresponding function, the water supply branch 140 is designed to include a second connecting pipe 141 and a first valve 142, and the water storage assembly 110 further includes a first water level sensor 112. The first end of the second connecting pipe 141 is used for accessing an external water source, and the second end of the second connecting pipe 141 is communicated with the water storage tank 111; the first valve 142 is arranged on the second connecting pipe 141; the first water level sensor 112 is used for monitoring the water level in the water storage tank 111, and when the first water level sensor 112 monitors that the water level in the water storage tank 111 is less than a first preset water level L, the first valve 142 is in a conducting state, so that an external water source flows into the water storage tank 111 through the second connecting pipe 141.

The specific connection mode between the second connection pipe 141 and the water storage tank 111 is not limited, and a designer can reasonably design according to actual needs; for example, the second connection pipe 141 may be detachably connected to the water storage tank 111 or may be non-detachably connected to the water storage tank; when the second connection pipe 141 is detachably connected to the water storage tank 111, the second connection pipe 141 may be connected to the water storage tank 111 by, but not limited to, screwing or clamping; when the second connection pipe 141 is non-detachably connected to the water storage tank 111, the second connection pipe 141 may be connected to the water storage tank 111 by, but not limited to, bonding, welding, or the like.

The first valve 142 corresponds to a pipeline on-off switch of the second connecting pipe 141, and the first valve 142 has an on state and an off state; when the first valve 142 is in the "on state", an external water source can flow from the second connection pipe 141 into the water storage tank 111; when the first valve 142 is in the "off state", the external water source cannot flow from the second connection pipe 141 into the water storage tank 111. It will be appreciated that the first valve 142 may be switched between the "on state" and the "off state" by a user, or may be switched automatically by a controller. For example, when the user needs to manually switch the first valve 142 between the "on state" and the "off state", if the first water level sensor 112 monitors that the water level in the water storage tank 111 is less than the first preset water level L, the first water level sensor 112 generates a first electrical signal, and the first electrical signal may enable a component such as a signal lamp or a buzzer of the water recovery device 100 to make a corresponding "prompt" so as to inform the user that the first valve 142 needs to be manually opened at this time. For another example, when the controller is required to automatically switch the first valve 142 between the "on state" and the "off state", if the first water level sensor 112 detects that the water level in the water storage tank 111 is less than the first preset water level L, the first water level sensor 112 generates a first electrical signal, and the controller of the water recovery device 100 controls the first valve 142 to be in the "on state" according to the first electrical signal.

By designing the first valve 142, the second connecting pipe 141 and the first water level sensor 112, the first water level sensor 112 can monitor the change of the water level in the water storage tank 111, when the first water level sensor 112 monitors that the water level in the water storage tank 111 is smaller than a first preset water level L, the first valve 142 is in a conducting state, and at the moment, an external water source can flow into the water storage tank 111 through the second connecting pipe 141 so as to supply water to the water storage tank 111 in time; when the first water level sensor 112 detects that the water level in the water storage tank 111 is greater than or equal to the first preset water level L, the first valve 142 is in the off state, and at this time, the external water source cannot flow into the water storage tank 111 through the second connection pipe 141.

Of course, in other embodiments, the water storage assembly 110 may not include the first water level sensor 112, and the user may directly observe the water level in the water storage tank 111 by eye and manually open the first valve 142 when the water level in the water storage tank 111 is visually detected to be lower than the first preset water level L.

Further, as shown in fig. 1 to 2, in order to prevent impurities from flowing into the water storage tank 111 from the second connection pipe 141 along with the external water source, considering that impurities may exist in the external water source connected to the second connection pipe 141, the water supply branch 140 is designed to further include a second filter 143, and the second filter 143 is disposed on the second connection pipe 141.

The second filter 143 may have a plurality of specific embodiments, and the second filter 143 may be disposed at different positions on the second connection pipe 141 for different embodiments of the second filter 143. For example, the second filter 143 may include a filter screen, which is disposed at a water inlet position of the first end of the second connection pipe 141 connected to the external water source; of course, the second filter 143 may also include a filter, and the filter is connected to the second connection pipe 141 in series.

By designing the second filter 143, the second filter 143 can effectively filter impurities in the external water source to ensure that the water flowing into the water storage tank 111 is clean water.

Further, as shown in fig. 1-2, in consideration of the situation that the water pressure in the water storage tank 111 is too high to damage the water storage tank 111 due to the excessive water level in the water storage tank 111, the water recovery device 100 is designed to further include a drainage branch 150, wherein the drainage branch 150 is communicated with the water storage tank 111, and the drainage branch 150 is used for draining part of the water in the water storage tank 111 out of the water storage tank 111 when the water level in the water storage tank 111 is greater than a third preset water level H.

The "third preset water level H" is understood to be a water level corresponding to the possibility that the water in the water storage tank 111 is excessively high to damage the water storage tank 111 due to excessive water in the water storage tank 111; the specific value of the third preset water level H is not limited, and a designer can reasonably design according to actual needs.

Specifically, the drain branch 150 includes a third connection pipe 151 and a second valve 152, and the water storage assembly 110 further includes a third water level sensor 114; a first end of the third connection pipe 151 is connected to the water storage tank 111, and a second end of the third connection pipe 151 extends to the outside; the second valve 152 is arranged on the third connecting pipe 151; the third water level sensor 114 is used for monitoring the water level in the water storage tank 111, and when the third water level sensor 114 monitors that the water level in the water storage tank 111 is greater than a third preset water level H, the second valve 152 is in a conducting state, so that the water in the water storage tank 111 is partially discharged out of the water storage tank 111 through the third connecting pipe 151.

The specific connection mode between the third connection pipe 151 and the water storage tank 111 is not limited, and a designer can reasonably design according to actual needs; for example, the third connection pipe 151 may be detachably connected to the water storage tank 111 or may be non-detachably connected to the water storage tank; when the third connection pipe 151 is detachably connected to the water storage tank 111, the third connection pipe 151 may be connected to the water storage tank 111 by, but not limited to, screwing or clamping; when the third connection pipe 151 is non-detachably connected to the water storage tank 111, the third connection pipe 151 may be connected to the water storage tank 111 by, but not limited to, bonding, welding, or the like.

The second valve 152 corresponds to a pipeline on-off switch of the third connecting pipe 151, and the second valve 152 has an on state and an off state; when the second valve 152 is in the "on state", the water portion in the water storage tank 111 can be led out from the third connection pipe 151 to the outside; when the second valve 152 is in the "off state", water in the water storage tank 111 cannot be drawn out of the third connection pipe 151 to the outside. It is understood that the switching manner of the second valve 152 between the "on state" and the "off state" may be a manual switching manner by a user or an automatic switching manner by a controller. For example, when the user is required to manually switch the second valve 152 between the "on state" and the "off state", if the third water level sensor 114 monitors that the water level in the water storage tank 111 is greater than the third preset water level H, the third water level sensor 114 generates a second electrical signal, and the second electrical signal may cause a signal lamp or a buzzer of the water recovery device 100 to make a corresponding "prompt" so as to inform the user that the second valve 152 needs to be manually opened at this time. For another example, when the controller is required to automatically switch the second valve 152 between the "on state" and the "off state", if the third water level sensor 114 detects that the water level in the water tank 111 is greater than the third preset water level H, the third water level sensor 114 generates a second electrical signal, and the controller controls the second valve 152 to be in the "on state" according to the second electrical signal. The on time of the second valve 152 may be a first preset time, which is understood as a time required to be able to drop the water pressure in the water storage tank 111 to a safe water pressure; the specific value of the first preset time is not limited, and a designer can reasonably design according to actual needs; and it is understood that the "first preset time" may be determined according to the total volume of the water storage tank 111 and the pipe diameter of the water outlet of the second end of the third connection pipe 151.

By designing the third connecting pipe 151, the second valve 152 and the third water level sensor 114, the third water level sensor 114 can monitor the change of the water level in the water storage tank 111, when the third water level sensor 114 monitors that the water level in the water storage tank 111 is greater than a third preset water level H, the second valve 152 is in a conducting state, and at the moment, the water part in the water storage tank 111 can be discharged out of the water storage tank 111 through the third connecting pipe 151, so that the water pressure in the water storage tank 111 is effectively reduced; when the third water level sensor 114 detects that the water level in the water storage tank 111 is less than or equal to the third preset water level H, the second valve 152 is in the off state, and at this time, the water pressure in the water storage tank 111 is not large, and the water in the water storage tank 111 does not need to be discharged out of the water storage tank 111 through the third connecting pipe 151.

Of course, in other embodiments, the water storage assembly 110 may not include the third water level sensor 114, and the user may directly observe the water level in the water storage tank 111 by eyes and manually open the second valve 152 when the water level in the water storage tank 111 is visually detected to be greater than the third preset water level H.

Further, as shown in fig. 1 to 2, the drain branch 150 is designed to further include a fourth connection pipe 153 and a third valve 154 in consideration of burst of the second connection pipe 141 in order to prevent the water accumulated in the pipe of the second connection pipe 141 from freezing when the outdoor environment temperature is low, for example, in winter. The first end of the fourth connection pipe 153 communicates with the second connection pipe 141, and the second end of the fourth connection pipe 153 communicates with the third connection pipe 151; the third valve 154 is provided in the fourth connection pipe 153, and when the third valve 154 is in the on state, the fourth connection pipe 153 can drain the accumulated water in the pipeline of the second connection pipe 141 through the third connection pipe 151.

When the external ambient temperature Tw is less than the third preset temperature T3, the third valve 154 is in a conducting state, and the "third preset temperature T3" is understood as a temperature corresponding to whether the water recovery device 100 needs to be opened in a winterized mode (i.e., to avoid icing accumulated water in the pipeline); the specific value of the third preset temperature T3 is not limited, and a designer can reasonably design according to actual needs; and it can be understood that the specific value of the third preset temperature T3 is also different in different countries or different areas of the same country. The third valve 154 corresponds to a line on-off switch of the fourth connection pipe 153, and the third valve 154 has an "on state" and an "off state"; when the third valve 154 is in the "on state", the accumulated water in the pipeline of the second connecting pipe 141 can be discharged out of the water storage tank 111 through the fourth connecting pipe 153 and the third connecting pipe 151 in sequence; when the third valve 154 is in the "off state", the accumulated water in the pipeline of the second connection pipe 141 cannot be discharged out of the water storage tank 111 through the fourth connection pipe 153 and the third connection pipe 151 in sequence. It is understood that the third valve 154 may be switched between the "on state" and the "off state" manually by a user or automatically by a controller. In the embodiment of the present application, the third valve 154 is a manual ball valve, and a user can manually switch the third valve 154 between the on state and the off state according to actual needs.

Further, as shown in fig. 1-2, the water storage assembly 110 is designed to further include the conductivity sensor 115 in consideration of the fact that when the quality of water is poor (i.e., the conductivity d1 of water is equal to or higher than the preset conductivity d0 described below), scale is easily formed on the surface of the condenser 210 after the water is sprayed onto the surface of the condenser 210 through the spraying branch 120, which shortens the service life of the condenser 210. The conductivity sensor 115 is used for monitoring the conductivity d1 of water, and when the conductivity sensor 115 monitors that the conductivity d1 of water is greater than or equal to the preset conductivity d0, the second valve 152 is in a conducting state, so that all the water in the water storage tank 111 is discharged out of the water storage tank 111 through the third connecting pipe 151.

The specific arrangement of the conductivity sensor 115 is not limited herein, for example, the conductivity sensor 115 may be connected in series to the sixth connection pipe 122 (described below) of the spray branch 120, and the conductivity sensor 115 may also be disposed in the water storage tank 111. The "preset conductivity d0" is understood as the impurity content contained in the water capable of forming scale on the surface of the condenser 210, and the specific value of the "preset conductivity d0" is not limited herein, so that a designer can reasonably design according to actual needs; and it can be understood that the specific value of the "preset conductivity d0" is not the same in different countries or in different areas of the same country. The on time of the second valve 152 may be a second preset time, and the "second preset time" is understood to be the time required for discharging all the water in the water storage tank 111 out of the water storage tank 111; the specific value of the second preset time is not limited, and a designer can reasonably design according to actual needs; and it is understood that the "second preset time" may be determined according to the total volume of the water storage tank 111 and the pipe diameter of the water outlet of the second end of the third connection pipe 151.

By designing the conductivity sensor 115, the conductivity sensor 115 can monitor the change of the conductivity d1 of the water, when the conductivity sensor 115 monitors that the conductivity d1 of the water is greater than or equal to the preset conductivity d0, the impurity in the water is excessive, at this time, the second valve 152 is in a conducting state, so that the water in the water storage tank 111 is completely discharged out of the water storage tank 111 through the third connecting pipe 151, and therefore, the water with excessive impurity is effectively prevented from being sprayed on the surface of the condenser 210 through the spraying branch 120 to form scale; when the conductivity sensor 115 detects that the conductivity d1 of the water is smaller than the preset conductivity d0, the impurity in the water is less or no impurity is contained in the water, at this time, the second valve 152 is in the off state, and the water in the water storage tank 111 cannot be discharged out of the water storage tank 111 through the third connecting pipe 151, so that the water can be sprayed for use next time.

It should be noted that, due to the design of the third connecting pipe 151 and the second valve 152 in the drain branch 150, on one hand, when the water level in the water storage tank 111 is greater than the third preset water level H, the second valve 152 is opened to drain the excessive water in the water storage tank 111 out of the water storage tank 111 through the third connecting pipe 151, so as to avoid damage to the water storage tank 111 caused by excessive water pressure in the water storage tank 111; on the other hand, the third connecting pipe 151 and the second valve 152 are equipped with the conductivity sensor 115, and when the conductivity sensor 115 detects that the conductivity d1 of the water is greater than or equal to the preset conductivity d0, the second valve 152 is opened to allow the impurities in the water storage tank 111 to be discharged out of the water storage tank 111 through the third connecting pipe 151, so that the whole system has a pollution discharge function.

Referring to fig. 2-3, a second aspect of the present application provides an air conditioner outdoor unit 200, wherein the air conditioner outdoor unit 200 includes a condenser 210 and the water recovery device 100. In this design, the air conditioner outdoor unit 200 having the water recovery device 100 can spray water in the water storage tank 111 onto the surface of the condenser 210, and the water sprayed onto the surface of the condenser 210 is evaporated into water vapor by absorbing heat of the surface of the condenser 210, so that the temperature of the surface of the condenser 210 is reduced, thereby improving the heat exchange efficiency of the condenser 210 and reducing the temperature of the condenser 210; the water sprayed to the condenser 210 but not completely evaporated can be recycled to the water storage tank 111, so that the purpose of recycling is achieved, and water resources can be saved to a certain extent; when the water level in the water storage tank 111 is smaller than the first preset water level L, the external water source can supply water to the water storage tank 111 through the water supply branch 140 in time, so that the water in the water storage tank 111 is ensured to be sufficient for the next spraying.

Referring to fig. 2, 4 and 5, a third aspect of the present application provides an air conditioning system 300, where the air conditioning system 300 includes the air conditioning outdoor unit 200, and the water tank 111 is a water tank with a heat preservation function; the air conditioning system 300 further includes an air conditioner indoor unit 310, the air conditioner indoor unit 310 including an evaporator 311 and a condensate recovery branch 312; the condensed water recovery branch 312 is communicated with the water storage tank 111, and the condensed water recovery branch 312 is used for recovering condensed water formed on the surface of the evaporator 311 into the water storage tank 111 when the water level in the water storage tank 111 is greater than or equal to a first preset water level L and less than a second preset water level M.

Based on the air conditioning system 300 in the embodiment of the present application, by designing the condensed water recovery branch 312, when the water level in the water storage tank 111 is greater than or equal to the first preset water level L and less than the second preset water level M, the condensed water recovery branch 312 can recover the condensed water formed on the surface of the evaporator 311 of the air conditioning system 300 into the water storage tank 111 so as to supply the condenser 210 for cooling; by designing the water storage tank 111 as a water tank with a heat preservation function, the water storage tank 111 with the heat preservation function can store the cold energy of condensed water so as to cool the condenser 210.

Specifically, the water storage tank 111 can be directly made of a material with a heat preservation effect, the specific preparation material of the water storage tank 111 is not limited, and a designer can reasonably select according to actual needs; the water storage tank 111 may be made of a material having no heat insulation function, and at least one heat insulation layer may be provided on the inner wall of the water storage tank 111 (directly selected in the prior art).

Further, as shown in fig. 2, 4 and 5, considering that the condensed water formed on the surface of the evaporator 311 can be recovered into the water storage tank 111 through the condensed water recovery branch 312, in order to provide the condensed water recovery branch 312 with a corresponding function, the condensed water recovery branch 312 is designed to include the evaporator 311 water receiving part, the fifth connection pipe 3122 and the drain pump 3123, and the water storage assembly 110 further includes the second water level sensor 113. The evaporator 311 water receiving piece is at least positioned at the bottom of the evaporator 311 and is used for receiving condensed water formed on the surface of the evaporator 311; a first end of the fifth connection pipe 3122 communicates with the evaporator 311 water receiving member; a second end of the fifth connection pipe 3122 communicates with the water storage tank 111; the water inlet of the drain pump 3123 is communicated with the evaporator 311 water receiving part, and the water outlet of the drain pump 3123 is communicated with the first end of the fifth connection pipe 3122; the second water level sensor 113 is used for monitoring the water level in the water storage tank 111, and when the second water level sensor 113 monitors that the water level in the water storage tank 111 is greater than or equal to the first preset water level L and less than the second preset water level M, the drain pump 3123 is in a conducting state, so that the condensed water in the water receiving part of the evaporator 311 flows into the water storage tank 111 through the fifth connecting pipe 3122.

The specific structure of the water receiving member of the evaporator 311 is not limited herein, and a designer may reasonably design according to actual needs, for example, the water receiving member of the evaporator 311 may be, but not limited to, a basin, a cylinder, a tray, etc. In the embodiment of the present application, the water receiving member of the evaporator 311 is a tray structure. The specific connection mode between the fifth connection pipe 3122 and the water receiving part of the evaporator 311 and between the fifth connection pipe 3122 and the water storage tank 111 is not limited, and a designer can perform reasonable design according to actual needs; for example, the fifth connection pipe 3122 may be detachably connected or non-detachably connected to the evaporator 311 (the water storage tank 111); when the fifth connection pipe 3122 is detachably connected to the evaporator 311 water receiving member (the water storage tank 111), the fifth connection pipe 3122 may be connected to the evaporator 311 water receiving member (the water storage tank 111) by, but not limited to, screwing or clamping; when the fifth connection pipe 3122 is non-detachably connected to the evaporator 311 water receiving member (water storage tank 111), the fifth connection pipe 3122 may be connected to the evaporator 311 water receiving member (water storage tank 111) by, but not limited to, bonding, welding, or the like.

The drain pump 3123 corresponds to a line on-off switch of the fifth connection pipe 3122, and the drain pump 3123 has an "on state" and an "off state"; when the drain pump 3123 is in the "on state", the condensed water in the water receiving part of the evaporator 311 can flow into the water storage tank 111 from the fifth connection pipe 3122; when the drain pump 3123 is in the "off state", the condensed water in the evaporator 311 water receiver cannot flow into the water storage tank 111 from the fifth connection pipe 3122. It is understood that the drain pump 3123 may be switched between the "on state" and the "off state" by a user, or by a controller. In the embodiment of the present application, when the second water level sensor 113 monitors that the water level in the water storage tank 111 is greater than or equal to the first preset water level L and less than the second preset water level M, the second water level sensor 113 generates a third electrical signal, and the controller controls the drain pump 3123 to be in a conducting state according to the third electrical signal, so that the condensed water in the water receiving part of the evaporator 311 can enter the water storage tank 111 through the fifth connection pipe 3122. It is understood that the drain pump 3123 may be switched between the "on state" and the "off state" by a user, or by a controller. For example, when the user is required to manually switch the drain pump 3123 between the "on state" and the "off state", if the second water level sensor 113 monitors that the water level in the water storage tank 111 is greater than or equal to the first preset water level L and less than the second preset water level M, the second water level sensor 113 generates a third electric signal, which may enable a component such as a signal lamp or a buzzer of the air conditioning system 300 to make a corresponding "prompt" to inform the user that the drain pump 3123 needs to be manually turned on at this time. For another example, when the controller is required to automatically switch the drain pump 3123 between the "on state" and the "off state", if the second water level sensor 113 monitors that the water level in the water storage tank 111 is greater than or equal to the first preset water level L and less than the second preset water level M, the second water level sensor 113 generates a third electric signal, and the controller controls the drain pump 3123 to be in the "on state" according to the third electric signal. It should be noted that, when the second water level sensor 113 monitors that the water level in the water storage tank 111 is greater than or equal to the second preset water level M and less than or equal to the third preset water level H, it indicates that the water amount in the water storage tank 111 is sufficient, and the water pressure in the water storage tank 111 is appropriate, and at this time, the drain pump 3123, the first valve 142 and the second valve 152 are all in the off state.

By designing the evaporator 311 water receiving part, the fifth connecting pipe 3122, the drainage pump 3123 and the second water level sensor 113, the second water level sensor 113 can monitor the change of the water level in the water storage tank 111, when the second water level sensor 113 monitors that the water level in the water storage tank 111 is greater than or equal to the first preset water level L and less than the second preset water level M, the drainage pump 3123 is in a conducting state, at this time, the condensed water in the evaporator 311 water receiving part can flow into the water storage tank 111 through the fifth connecting pipe 3122, so as to realize the recycling of the condensed water; when the second water level sensor 113 detects that the water level in the water storage tank 111 is smaller than the first preset water level L or greater than the second preset water level M, the drain pump 3123 is in the off state, and the water amount in the water storage tank 111 is sufficient, and the condensed water in the water receiving part of the evaporator 311 cannot flow into the water storage tank 111 through the fifth connection pipe 3122. In addition, by designing the drain pump 3123, the condensed water in the water receiving part of the evaporator 311 flows into the water storage tank 111 through the fifth connection pipe 3122 under the action of the drain pump 3123, thereby improving portability of the condensed water in the water receiving part of the evaporator 311 into the water storage tank 111.

Of course, in other embodiments, the water storage assembly 110 may not include the second water level sensor 113, and the user may directly observe the water level in the water storage tank 111 by eyes and manually turn on the drain pump 3123 when the water level in the water storage tank 111 is visually detected to be greater than or equal to the first preset water level L and less than the second preset water level M.

In particular, the other structural members of the condensate recovery branch 312, the particular form of the evaporator 311 water receiver, may be, but are not limited to, one or more of the following implementations.

In the first embodiment, the evaporator 311 water receiving member includes an evaporator 311 water receiving tray, the evaporator 311 water receiving tray has an overflow port 3125, and the overflow port 3125 is disposed closer to the tray port of the evaporator 311 water receiving tray than to the tray bottom of the evaporator 311 water receiving tray. By designing the overflow port 3125, the excessive condensed water in the evaporator 311 water pan can be discharged out of the evaporator 311 water pan through the overflow port 3125 in time.

In the second embodiment, the condensed water recovery branch 312 further includes a one-way valve 3124, the one-way valve 3124 being provided on the fifth connection pipe 3122, the one-way valve 3124 being configured to allow condensed water to flow only from the water receiving part of the evaporator 311 to the water storage tank 111. By designing the one-way valve 3124, water in the storage tank 111 cannot flow back from the storage tank 111 into the evaporator 311 receptacle. It should be noted that, when the second end of the fifth connection pipe 3122 is in communication with the water storage tank 111 through the second connection pipe 141, the one-way valve 3124 can also limit the supply of external water source into the water receiving part of the evaporator 311.

Further, as shown in fig. 2, 4 and 5, considering that the spray branch 120 is a structure for spraying water stored in the water storage tank 111 to the surface of the condenser 210 to cool the condenser 210, in order to provide the spray branch 120 with a corresponding function, the spray branch 120 is designed to include a nozzle assembly 121, a sixth connection pipe 122 and a spray water pump 123, and the air conditioning system 300 includes a first temperature sensor 313 and a second temperature sensor 314. The nozzle assembly 121 is disposed toward the condenser 210; a first end of the sixth connection pipe 122 communicates with the nozzle assembly 121, and a second end of the sixth connection pipe 122 communicates with the water storage tank 111; the spray water pump 123 is communicated with the sixth connecting pipe 122; the first temperature sensor 313 is used for monitoring the outdoor environment temperature, the second temperature sensor 314 is used for monitoring the discharge temperature Tp of the compressor of the air conditioning system 300, and the spray water pump 123 is in a conducting state when the outdoor environment temperature monitored by the first temperature sensor 313 is greater than a first preset temperature T1 and the discharge temperature Tp of the compressor of the air conditioning system 300 monitored by the second temperature sensor 314 is greater than a second preset temperature T2.

The nozzle assembly 121 includes nozzle tubes, and the number of the nozzle tubes may be one or plural (two or more). The specific connection mode between the sixth connection pipe 122 and the water storage tank 111 is not limited, and a designer can reasonably design according to actual needs; for example, the sixth connection pipe 122 may be detachably connected to the water storage tank 111 or may be non-detachably connected to the water storage tank; when the sixth connection pipe 122 is detachably connected to the water storage tank 111, the sixth connection pipe 122 may be connected to the water storage tank 111 by, but not limited to, screwing or clamping; when the sixth connection pipe 122 is non-detachably connected to the water storage tank 111, the sixth connection pipe 122 may be connected to the water storage tank 111 by, but not limited to, bonding, welding, or the like.

The spray water pump 123 corresponds to a pipeline on-off switch of the sixth connecting pipe 122, and the spray water pump 123 has an on state and an off state; when the spray water pump 123 is in the "on state", the water in the water storage tank 111 can be sprayed to the surface of the condenser 210 through the sixth connection pipe 122 and the nozzle assembly 121 in sequence; when the spray water pump 123 is in the "off state", the water in the water storage tank 111 cannot be sprayed to the surface of the condenser 210 through the sixth connection pipe 122 and the nozzle assembly 121 in sequence. It can be understood that the switching manner of the spray water pump 123 between the "on state" and the "off state" may be implemented by a manual switching manner of a user or may be implemented by an automatic switching manner of a controller. For example, when the user is required to manually switch the drain pump 3123 between the "on state" and the "off state", if the first temperature sensor 313 monitors that the outdoor environment temperature is greater than the first preset temperature T1 and the second temperature sensor 314 monitors that the discharge temperature Tp of the compressor of the air conditioning system 300 is greater than the second preset temperature T2, the first temperature sensor 313 and the second temperature sensor 314 together generate a fourth electrical signal, which may enable components such as a signal lamp or a buzzer of the air conditioning system 300 to make a corresponding "prompt" to inform the user that the spray water pump 123 needs to be manually turned on at this time. For another example, when the controller is required to automatically switch the drain pump 3123 between the "on state" and the "off state", if the first temperature sensor 313 monitors that the outdoor environment temperature is greater than the first preset temperature T1 and the second temperature sensor 314 monitors that the discharge temperature Tp of the compressor of the air conditioning system 300 is greater than the second preset temperature T2, the first temperature sensor 313 and the second temperature sensor 314 together generate a fourth electrical signal, and the controller controls the spray water pump 123 to be in the "on state" according to the fourth electrical signal.

The "first preset temperature T1" is understood to be an ambient temperature value corresponding to the need to perform water spraying and cooling on the condenser 210; the specific value of the first preset temperature T1 is not limited, and a designer can reasonably design according to actual needs; and it can be understood that the specific value of the "first preset temperature T1" is also different in different countries or in different areas of the same country. The second preset temperature T2 is understood to be a temperature value corresponding to whether the refrigerating system of the air conditioning system operates or not; the specific value of the second preset temperature T2 is not limited, and a designer can reasonably design according to actual needs; and it can be understood that the specific value of the "second preset temperature T2" is also different in different countries or in different areas of the same country. It should be noted that, the second preset temperature T2 is used to determine whether the refrigeration system of the air conditioning system 300 is operating, and if the refrigeration system of the air conditioning system 300 is not operating, the spray water pump 123 is not required to be turned on. The second preset temperature T2 is on the other hand used to determine whether the compressor is in high-frequency operation by the exhaust temperature Tp, and only in high-frequency operation, the spraying is started most efficiently, so that the purposes of reducing the frequency of the compressor and improving the energy efficiency of the air conditioning system 300 can be achieved.

By designing the nozzle assembly 121, the sixth connecting pipe 122, the spray water pump 123, the first temperature sensor 313 and the second temperature sensor 314, when the first temperature sensor 313 monitors that the outdoor environment temperature is greater than the first preset temperature T1 and the second temperature sensor 314 monitors that the exhaust temperature Tp of the compressor of the air conditioning system 300 is greater than the second preset temperature T2, the spray water pump 123 is in a conducting state, and at this time, water in the water tank 111 can be sprayed to the surface of the condenser 210 through the sixth connecting pipe 122 and the nozzle assembly 121 in sequence, so as to cool the condenser 210; when the first temperature sensor 313 monitors that the outdoor ambient temperature is less than or equal to the first preset temperature T1 or the second temperature sensor 314 monitors that the discharge temperature Tp of the compressor of the air conditioning system 300 is less than or equal to the second preset temperature T2, the spray water pump 123 is in an off state, and at this time, water in the water storage tank 111 cannot be sprayed to the surface of the condenser 210 through the sixth connection pipe 122 and the nozzle assembly 121 in sequence.

Of course, in other embodiments, the spray branch 120 further includes a third filter 124, where the third filter 124 is a filter, and the filter is serially connected to the sixth connection pipe 122.

Note that, the fourth valve 156 corresponds to a line on-off switch of the seventh connection pipe 155, and the fourth valve 156 has an "on state" and an "off state"; when the fourth valve 156 is in the "on state", the accumulated water in the sixth connection pipe 122 can be led out to the outside through the seventh connection pipe 155 and the third connection pipe 151 in sequence; when the fourth valve 156 is in the "off state", the accumulated water in the pipeline of the sixth connection pipe 122 cannot be led out to the outside through the seventh connection pipe 155 and the third connection pipe 151 in sequence. It is understood that the fourth valve 156 may be switched between the "on state" and the "off state" by a user, or may be switched automatically by a controller. In the embodiment of the present application, the fourth valve 156 is a manual ball valve, and a user can manually switch the fourth valve 156 between the on state and the off state according to actual needs.

It should be noted that, the air conditioning system 300 may be an air conditioning integrated machine or an air conditioning split machine. The water level monitoring in the water storage tank 111 may also be achieved by a water level sensor capable of simultaneously monitoring the relationship between the water level in the water storage tank 111 and the first preset water level L, the second preset water level M, and the third preset water level H. The first water level sensor 112, the second water level sensor 113, the third water level sensor 114, the conductivity sensor 115, the first temperature sensor 313 and the second temperature sensor 314 may be simultaneously controlled by one controller or may be separately controlled by a plurality of controllers, which is not limited herein.

A fourth aspect of the present application provides an air conditioning system control method, as shown in fig. 6, fig. 6 is a schematic flow chart of an air conditioning system control method according to an embodiment of the present application, and the air conditioning system control method shown in fig. 6 includes step S201 and step S202.

Step S201: the water level in the water storage tank 111 is acquired.

In step S201, a first water level sensor 112 is disposed in the water storage tank 111, and the first water level sensor 112 is used to monitor the water level of water in the water storage tank 111.

Step S202: when the water level is less than the first preset water level L, the water supply branch 140 is controlled to be turned on to supply water into the water storage tank 111; when the water level is greater than or equal to the first preset water level L and the air conditioning system 300 meets the preset spraying condition, the spraying branch 120 is controlled to spray water to the condenser 210 of the air conditioning system 300 so as to cool the condenser 210, and the water sprayed to the condenser 210 but not completely evaporated is recovered into the water storage tank 111 through the spraying water recovery branch 130.

In step S202, the "first preset water level L" is understood to mean that the water in the water storage tank 111 cannot be drawn out from the water storage tank 111 and sprayed to the water level corresponding to the condenser 210 under the action of the spraying branch 120, or that the water in the water storage tank 111 can be drawn out from the water storage tank 111 and sprayed to the water level corresponding to the condenser 210 under the action of the spraying branch 120 (but the drawn water contains a part of air, resulting in insufficient spraying). The water supply branch 140 includes a second connection pipe 141 and a first valve 142. When the first water level sensor 112 detects that the water level in the water storage tank 111 is less than the first preset water level L, the first valve 142 is controlled to be in a conductive state, so that the external water source flows into the water storage tank 111 through the second connection pipe 141. The spray branch 120 includes a nozzle assembly 121, a sixth connection pipe 122, and a spray water pump 123, and the air conditioning system 300 includes a first temperature sensor 313 and a second temperature sensor 314. The shower water recovery branch 130 includes a condenser 210 water receiving part and a first connection pipe 132. When the first water level sensor 112 monitors that the water level in the water storage tank 111 is greater than or equal to a first preset water level L and the air conditioning system 300 meets a preset spraying condition, the spraying water pump 123 is controlled to be in a conducting state, so that water in the water storage tank 111 is sprayed to the condenser 210 of the air conditioning system 300 through the sixth connecting pipe 122 and the spraying assembly in sequence, and the temperature of the condenser 210 is reduced; and the water droplets sprayed to the condenser 210 but not completely evaporated fall into the water receiving member of the condenser 210 and are returned to the water storage tank 111 through the first connection pipe 132.

It should be noted that, the two steps of "the water level is greater than or equal to the first preset water level L and the air conditioning system 300 meets the preset spraying condition" are not strict in sequence, and whether the spraying condition is met can be judged first and then whether the water level is met is judged; or judging whether the water level is met or not, and judging whether the spraying condition is met or not.

Specifically, the air conditioning system 300 satisfying the preset spraying condition specifically includes that the outdoor ambient temperature is greater than the first preset temperature T1, and the discharge temperature Tp of the compressor of the air conditioning system 300 is greater than the second preset temperature T2.

It should be noted that, only when the outdoor ambient temperature is greater than the first preset temperature T1 and the exhaust temperature Tp of the compressor of the air conditioning system 300 is greater than the second preset temperature T2, the air conditioning system 300 is considered to satisfy the preset spraying condition, and only when the outdoor ambient temperature is greater than the first preset temperature T1 and at least one of the exhaust temperature Tp of the compressor of the air conditioning system 300 is greater than the second preset temperature T2 is not satisfied, the air conditioning system 300 is considered to not satisfy the preset spraying condition.

Based on the air conditioning system control method in the embodiment of the application, when the water level in the water storage tank 111 is smaller than the first preset water level L, the water supply branch 140 is controlled to be conducted so as to supply water into the water storage tank 111, so that the water in the water storage tank 111 is ensured to be sufficient for the next spraying use; when the water level in the water storage tank 111 is greater than or equal to a first preset water level L and the air conditioning system 300 meets a preset spraying condition, the spraying branch 120 is controlled to spray water to the condenser 210 of the air conditioning system 300, and the water sprayed on the surface of the condenser 210 is evaporated into water vapor by absorbing heat on the surface of the condenser 210, so that the temperature of the surface of the condenser 210 is reduced, and the heat exchange efficiency of the condenser 210 is improved to cool the condenser 210; the spray water recycling branch 130 can recycle the water sprayed to the condenser 210 but not completely evaporated into the water storage tank 111, thereby achieving the purpose of recycling and saving water resources to a certain extent.

Further, as shown in fig. 7, fig. 7 is a flow chart of another control method of an air conditioning system according to an embodiment of the present application; as shown in fig. 7, after the step S201, step S301 and step S302 are further included.

Step S301: when the water level is greater than or equal to the first preset water level L and less than the second preset water level M, the condensate water recovery branch 312 is controlled to be conducted, so that condensate water formed on the surface of the evaporator 311 of the air conditioning system 300 is recovered into the water storage tank 111 through the condensate water recovery branch 312.

In step S301, a second water level sensor 113 is further disposed in the water tank 111, and the second water level sensor 113 is used for monitoring the water level of the water in the water tank 111. The condensed water recovery branch 312 includes an evaporator 311 water receiving part, a fifth connection pipe 3122, and a drain pump 3123. When the second water level sensor 113 detects that the water level in the water storage tank 111 is greater than or equal to the first preset water level L and less than the second preset water level M, the drain pump 3123 is controlled to be in a conductive state, so that the condensed water in the water receiving part of the evaporator 311 flows into the water storage tank 111 through the fifth connection pipe 3122.

Step S302: when the water level is greater than or equal to the second preset water level M, the condensed water recovery branch 312 is controlled to be turned off.

In step S302, when the second water level sensor 113 detects that the water level in the water storage tank 111 is greater than the second preset water level M, the drain pump 3123 is controlled to be in an off state so that the condensed water in the water receiving part of the evaporator 311 cannot flow into the water storage tank 111 through the fifth connection pipe 3122.

Further, as shown in fig. 8, fig. 8 is a flow chart of another control method of an air conditioning system according to an embodiment of the present application; as shown in fig. 8, step S401 is further included after step S201.

Step S401: when the water level is greater than the third preset water level H, the drain branch 150 is controlled to be turned on, so that water in the water storage tank 111, which is higher than the third preset water level H, is drained out of the water storage tank 111 through the drain branch 150.

In step S401, the "third preset water level H" is understood to be a water level corresponding to the possibility that the water in the water storage tank 111 is excessively high, resulting in an excessive water pressure in the water storage tank 111, to damage the water storage tank 111. A third water level sensor 114 is also provided in the water storage tank 111, the third water level sensor 114 being for monitoring the water level of the water in the water storage tank 111. The drain branch 150 includes a third connection pipe 151 and a second valve 152. When the third water level sensor 114 detects that the water level in the water storage tank 111 is greater than the third preset water level H, the second valve 152 is controlled to be in a conductive state, so that water in the water storage tank 111, which is higher than the third preset water level H, is discharged out of the water storage tank 111 through the third connection pipe 151.

Further, the air conditioning system control method further includes step S501 and step S502.

Step S501: the conductivity d1 of the water is obtained.

In step S501, the conductivity d1 of the water is monitored by the conductivity sensor 115.

Step S502: when the conductivity is greater than the preset conductivity d0, the water supply branch 140, the condensed water recovery branch 312 and the spraying branch 120 are controlled to be turned off, and the drain branch 150 is controlled to be turned on, so that all water in the water storage tank 111 is drained out of the water storage tank 111 through the drain branch 150.

In step S502, the "preset conductivity d0" is understood to be the impurity content contained in the water capable of forming scale on the surface of the condenser 210. When the conductivity sensor 115 detects that the conductivity d1 of the water is greater than the preset conductivity d0, the first valve 142 is controlled to be in the off state, the drain pump 3123 is controlled to be in the off state, the spray pump 123 is controlled to be in the off state, and the second valve 152 is controlled to be in the on state, so that all the water in the water storage tank 111 is discharged out of the water storage tank 111 through the third connection pipe 151.

Further, the air conditioning system control method further includes step S601 and step S602.

Step S601: an outdoor ambient temperature is obtained.

In step S601, the outdoor ambient temperature is monitored by the first temperature sensor 313.

Step S602: when the outdoor ambient temperature is less than the third preset temperature T3, the drainage branch 150 is controlled to be turned on, so that the accumulated water in the pipeline of the water supply branch 140 is drained through the drainage branch 150.

In step S602, the "third preset temperature T3" is understood to be the temperature corresponding to whether the water recovery device 100 needs to be turned on in the winterized mode (i.e. to avoid icing the accumulated water in the pipeline). The drain branch 150 further includes a fourth connection pipe 153 and a third valve 154. When the first temperature sensor 313 monitors that the outdoor ambient temperature is less than the third preset temperature T3, the third valve 154 is controlled to be in a conductive state, so that the accumulated water in the pipeline of the second connection pipe 141 is discharged through the third connection pipe 151.
