With reference to fig. 1 to 4, the embodiment of the present disclosure provides a spraying system for an outdoor heat exchanger 10, which includes a water tank 30, a spray header 20, a water pump, a heating device, and a control module, wherein the water tank 30 is provided with a water inlet and a water outlet; the spray pipe 20 is communicated with the water outlet, the spray pipe 20 comprises a spray box 31, and the spray box 31 is provided with a plurality of spray holes 32 with adjustable apertures; the water pump is connected with the spray header 20; a heating device disposed in the water tank 30; the control module is configured to control an operation state of the heating device according to an operation state of the air conditioner.
The spray system is used for spraying the outdoor heat exchanger 10. When the air conditioner refrigerates, liquid refrigerant is evaporated by the indoor heat exchanger to absorb heat, enters the compressor to become high-temperature high-pressure gaseous refrigerant, then is radiated by the outdoor heat exchanger 10 to become low-temperature gaseous refrigerant, then becomes liquid refrigerant under the throttling action of the throttling device, enters the indoor heat exchanger, and circulates in a reciprocating mode in such a way that indoor heat is conveyed to the outdoor. In the whole circulation process, the heat dissipation of the refrigerant in the outdoor heat exchanger 10 is very critical. In the disclosed embodiment, the water tank 30 is used for storing shower water, the shower pipe 20 is connected to the water tank 30, and the water pump provides a spraying pressure for the spraying system. The water outlet aperture refers to the sectional area of water flow passing through the spraying holes 32 during spraying, the spraying box 31 is provided with a plurality of spraying holes 32 with adjustable water outlet aperture, and the flow, pressure and distance of spraying can be changed by adjusting the water outlet aperture of the spraying holes under the condition that the water supply pressure is certain, so that the spraying system is more accurate in controlling the spraying.
Use the spraying system that this disclosed embodiment provided, can spray outdoor heat exchanger 10 when the air conditioner refrigerates, on the one hand, thereby the shower water carries out the heat exchange with outdoor heat exchanger 10 and cools down outdoor heat exchanger 10, and on the other hand, the water that sprays outdoor heat exchanger 10 makes outdoor heat exchanger 10 surface become the state of moistening wet, and the water on heat exchanger surface absorbs a large amount of heats evaporation into the gassiness from outdoor heat exchanger 10 under outdoor fan's effect to cool down outdoor heat exchanger 10.
When the air conditioner heats, the refrigerant is circulated reversely, the liquid refrigerant absorbs heat through the outdoor heat exchanger 10 to become a gaseous refrigerant, the gaseous refrigerant becomes a high-temperature and high-pressure gaseous refrigerant through the compressor, the temperature of the gaseous refrigerant is reduced under the action of the indoor fan through the indoor heat exchanger, the gaseous refrigerant becomes a liquid refrigerant through the throttling device, the liquid refrigerant enters the outdoor heat exchanger 10, and the circulation is repeated. The temperature of the outdoor heat exchanger 10 is relatively low, and water vapor in the air is easily condensed on the outdoor heat exchanger 10 to form a frost layer. The frost layer of the outdoor heat exchanger 10 may affect the heat exchange between the outdoor heat exchanger 10 and the outdoor environment, and may affect the normal operation of the air conditioner for heating if the outdoor heat exchanger 10 is not defrosted. By using the spraying system provided by the embodiment of the present disclosure, the control module controls the heating device to operate, so that the water in the water tank 30 has a higher temperature, then the water pump provides power, and the spraying system sprays hot water to the outdoor heat exchanger 10. The hot water spray can melt the frost layer of the outdoor heat exchanger 10 relatively quickly so that the heating of the air conditioner can be continuously performed.
By using the spraying system provided by the embodiment of the disclosure, the outdoor heat exchanger 10 can be sprayed to assist the air conditioner to refrigerate when the air conditioner refrigerates, and hot water can be sprayed to the outdoor heat exchanger 10 to defrost when the air conditioner needs defrosting, so that the refrigerating and defrosting processes of the air conditioner are optimized, the energy efficiency of the air conditioner is improved, and the use experience of a user is improved.
Alternatively, controlling the operation state of the heating device according to the operation state of the air conditioner includes controlling the heating device to be turned off when the operation state of the air conditioner is the cooling mode, and controlling the heating device to be turned on when the operation state of the air conditioner is the heating mode. When the air conditioner is refrigerating, the outdoor heat exchanger 10 is sprayed with low-temperature spray water or normal-temperature spray water without starting a heating device; when the air conditioner heats, the outdoor environment temperature is low, and the heating device is controlled to be turned on in order to make the water in the water tank 30 have good fluidity and a certain temperature. When the air conditioner performs heating, the temperature of the outdoor heat exchanger 10 is gradually reduced along with the heating operation, and the possibility of frosting of the outdoor heat exchanger 10 is increased, so that the water temperature is increased under the condition that the air conditioner enters a heating mode, and thus, when the air conditioner performs defrosting, heated water can be sprayed at the first time, and thus, the defrosting efficiency can be improved. In the embodiment of the present disclosure, the hot water, the cold water, and the normal temperature water are hot, cold, and normal temperature compared to the outdoor heat exchanger 10 and the outdoor ambient temperature, and no comparison is made between the three. For example, when the air conditioner is defrosted, the surface temperature of the outdoor heat exchanger 10 is lower than zero, and the outdoor environment temperature is also lower than zero, and the hot water refers to water having a temperature higher than the surface temperature of the outdoor heat exchanger 10 or higher than the outdoor environment temperature. Specifically, when the air conditioner is refrigerating, the outdoor environment temperature is thirty degrees celsius, the surface temperature of the outdoor heat exchanger 10 is forty-five degrees celsius, and the temperature of the normal-temperature water in the spray water tank 30 is thirty degrees celsius; when the air conditioner is defrosted, the outdoor environment temperature is below zero, the surface temperature of the outdoor heat exchanger 10 is below zero, and the temperature of the spray hot water is two degrees centigrade. Alternatively, when the air conditioner heats, the heating device is controlled to be turned on to increase the temperature of the water tank 30 to the first preset temperature. Optionally, the first preset temperature is two degrees celsius. The higher the temperature of water in the water tank 30 is, the better the defrosting effect is, but the higher the power consumption required for the heating means to raise the temperature of the water tank 30 is, the more heat the water tank 30 loses by heat transfer. When the outdoor heat exchanger 10 is defrosted, the water in the water tank 30 can ensure a better defrosting effect at two degrees centigrade, and does not need much electric quantity to raise the water temperature.
Alternatively, controlling the operation state of the heating device according to the operation state of the air conditioner includes controlling the heating device to be turned on to increase the temperature of the water in the water tank 30 to a first preset temperature when the operation state of the air conditioner is the defrosting mode. In a use scene with low defrosting frequency, the temperature of the water in the water tank 30 is higher than the temperature of the outdoor environment, the water tank 30 can exchange heat with the outdoor environment, and the water temperature is kept at the first preset temperature for a long time, which causes heat waste, therefore, when the running state of the air conditioner is in a defrosting mode, the heating device is controlled to be started to raise the temperature of the water tank 30 to the first preset temperature, although the temperature of the water tank 30 has a certain hysteresis for the defrosting requirement of the air conditioner, the requirement of the air conditioner running defrosting mode for the temperature of the spray water can be met with low power consumption.
Optionally, the heating device includes a heating component, a power supply component and a power regulating module, wherein the heating component is located in the water tank 30; the power supply assembly is connected with the heating assembly; the power adjusting module is connected to the heating component and is used for controlling the heating power of the heating component. The electric heating device can make the heating device independent of the refrigerant circulating system of the air conditioner. Compared with the mode of defrosting the outdoor heat exchanger 10 by switching the flowing direction of the refrigerant, the electric heating device is used for increasing the temperature of the water tank 30 without changing the flowing direction of the refrigerant, so that the indoor heating can be continuously operated, the heating interruption caused by defrosting does not influence the user experience, and the method is particularly important when the weather is relatively cold and the heating requirement of the air conditioner is relatively high. The power adjusting module can adjust the power of the heating device, and further, the heating speed of the water tank 30 can be adjusted, so that the temperature of the water tank 30 can be adjusted more flexibly according to the outdoor environment temperature, the temperature of the water tank 30 and the first preset temperature. Optionally, the control means also determines the power of the heating means on the basis of a first difference between the temperature of the water tank 30 and a first preset temperature. The temperature of the water tank 30 is the temperature of the water in the water tank 30, and when the difference between the temperature of the water tank 30 and the first preset temperature is large, the temperature of the water tank 30 is low, and the amount of heat required for the temperature of the water tank 30 to reach the first preset temperature is large. At this time, the heating device is controlled to operate at a higher power, so that the time required for increasing the temperature of the water tank 30 to the first preset temperature can be shortened, and thus the spray system can effectively defrost the outdoor heat exchanger 10 in time when the air conditioner needs defrosting. When the first difference between the temperature of the water tank 30 and the first preset temperature is small, the temperature of the water tank 30 is relatively high, and the amount of heat required for the temperature of the water tank 30 to reach the first preset temperature is small. At this moment, the heating device is controlled to operate at lower power, so that the temperature rise of the water tank 30 can be gentle, the electric quantity lost due to circuit heating in the process of the temperature rise of the water tank 30 by the heating device is less, the power consumption required by the temperature rise can be reduced, and the service life of the heating device can be prolonged.
Optionally, the tank 30 includes an outer housing and an inner housing, wherein the inner housing defines a cavity for containing shower water. The water tank 30 is composed of an outer shell and an inner shell, and an interlayer between the inner shell and the outer shell can play a role in heat preservation of water in the water tank 30. Meanwhile, the double-layered case structure makes the water tank 30 more firm. Optionally, the outer casing of the water tank 30 is coated with a thermal insulation material, so that the water in the water tank 30 can be better insulated. Optionally, the heat insulation material is a foam material, and the foam material is loose and porous, so that better heat storage and heat insulation can be performed.
Optionally, the outer shell and the inner shell form a heating chamber, and the heating assembly is disposed in the heating chamber. The intermediate layer between shell body and the interior casing is heating chamber, and the heat that heating element produced transmits the cavity that holds the shower water in through interior casing. The heating cavity is separated from the cavity for containing the spray water through the inner shell, the spray water which is caused by electric leakage of the heating component can be effectively prevented from being electrified, the risk of electric shock of personnel can be avoided, and the air conditioner can be prevented from being damaged by the electrified spray water.
Optionally, the heating component is a heating wire, and the heating wire is wound around the inner shell. This form is low in cost and easy to implement, and the heating wire is used as a heating component to heat the water in the water tank 30, so that the heat efficiency is high. The heater twines in interior casing can improve the heat exchange efficiency of heater and interior casing to improve the heat exchange efficiency of heater and the water that holds in the cavity of shower water, furtherly, improve heating device and carry out the efficiency of heating to the shower water.
Optionally, the outer shell and the inner shell are filled with heat exchange media. Like this, the heat that heating element produced can carry out abundant heat exchange with heat transfer medium, and heat transfer medium and interior casing fully contact, has just also improved the heat exchange efficiency of heating element with interior casing, and further, has improved the heating efficiency of heating device to the water in the cavity that holds the shower water. Optionally, the heat exchange medium is a heat exchange oil. The heat-conducting property of heat exchange oil is better, and is insulating moreover, uses heat exchange oil not only can improve heating device to the heating efficiency who holds the water in the cavity of shower water as heat transfer medium, can also effectively improve the electrical safety.
Optionally, the water pump is a submersible pump, the submersible pump is located in the water tank 30 and connected to the water outlet, and the shower pipe 20 is connected to the submersible pump through the water outlet. In the embodiment of the present disclosure, the submersible pump is divided according to the installation form of the water pump, and the submersible pump refers to a water pump which can be immersed in water. Set up the immersible pump, the water pump is located water tank 30, and when water tank 30 when spray system was far away apart from the outer quick-witted heat exchanger of air-conditioner or spray system had higher requirement to the lift of water pump, chooseed for use the immersible pump can improve the pump sending ability of water pump, and in addition, the water pump is located water tank 30 and can makes spray system's wholeness better.

The embodiment of the present disclosure provides an air conditioner including the above-described shower system for the outdoor heat exchanger 10.
Optionally, the air conditioner further includes a first water pan disposed below the outdoor heat exchanger 10 and provided with a first water drainage port, wherein the water tank 30 is further provided with a water return port, and the first water drainage port is connected to the water return port. When the air conditioner outdoor heat exchanger 10 is in heating operation, when the temperature of the outdoor heat exchanger 10 is below the condensation point temperature, the outdoor heat exchanger 10 can generate condensed water; when the air conditioner is refrigerating, the spraying system sprays the outdoor heat exchanger 10, one part of water is evaporated, and the other part of water flows to the lower part of the outdoor heat exchanger 10 along the outdoor heat exchanger 10; when the air conditioner defrosts, the spray system performs spray defrosting on the outdoor heat exchanger 10, and water generated by defrosting and spray water flow along the outdoor heat exchanger 10 to the lower side of the outdoor heat exchanger 10. If the water is not utilized, the waste of water resources is caused. Therefore, a first water receiving tray is arranged below the outdoor heat exchanger 10, a first water discharging opening is formed in the water receiving tray, and water generated by condensation, spray water and defrosting water can return to the water tank 30 through the first water discharging opening and a water returning opening of the water tank 30 through the water receiving tray. Therefore, the utilization rate of water resources is improved.
Optionally, first water collector still is provided with the drain, and the drain is provided with the blowoff valve, and first drain is provided with the drain valve. The outdoor heat exchanger 10 may have a surface that is dusty after a long time operation, and if the sewage enters the water tank 30, the spray pipe 20 may be blocked or the water pump may be damaged. Therefore, when the air conditioner is cleaned, the sewage generated is discharged through the drain outlet, and clean circulating water is introduced into the water tank 30 through the first drain outlet.
Optionally, a conductivity sensor is arranged in the first water pan, and when the conductivity of the water in the first water pan is higher, the water in the first water pan is considered to be dirty and needs to be drained through a drain outlet; if the conductivity of the water in the first drip tray is low, the water in the first drip tray is considered to be relatively clean and may return to the water tank 30 through the drain opening. The arrangement of the conductivity meter can be used for judging the cleaning success of the water in the water pan more accurately by the air conditioner.
Optionally, the waste outlet is positioned below the drain outlet. Like this, when the water impurity in the first water collector is more, great granule or dust can deposit in the bottom of first water collector, and the position of drain is less than the outlet, not only can prevent that the precipitate from passing through the outlet and getting into water tank 30, does not influence the precipitate moreover and normally blowdown from the drain.
Optionally, the air conditioner further includes an indoor heat exchanger and a second water pan, wherein the second water pan is disposed below the indoor heat exchanger and provided with a second water outlet, the water tank 30 is further provided with a water return port, and the second water outlet is connected to the water return port. When the air conditioner refrigerates or dehumidifies, water vapor in the indoor air can condense on the surface of the indoor heat exchanger to form a large amount of condensed water, and a second water receiving disc positioned below the indoor heat exchanger can receive water generated by the indoor heat exchanger. The second drip pan is provided with a second drain port for allowing condensed water to return to the water tank 30. Such setting form can effectively improve the utilization ratio to the water resource.
Optionally, the spraying system further comprises an aperture adjusting device for adjusting the water outlet aperture of the spraying water pipe 20. The outlet aperture is the cross-sectional area of the water flow passing through the spray holes 32 during spraying. When the air conditioner sprays the outdoor heat exchanger 10, the flow, the water outlet pressure and the spraying distance of the spraying water can be changed by changing the aperture of the spraying holes 32, when the water supply pressure of the spraying pipe is fixed, the flow, the water outlet pressure and the spraying distance of the spraying water can be changed by changing the aperture of the spraying holes 32, and further, the flow, the water outlet pressure and the spraying distance of the spraying water can be adjusted by adjusting the aperture of the spraying holes 32.
Optionally, the aperture adjusting device includes a bottom aperture adjusting piece 33 slidably connected to the spraying box 31, wherein the aperture adjusting piece 33 is provided with a plurality of adjusting holes 34 corresponding to the plurality of spraying holes 32 of the spraying and the bottom, when the aperture adjusting piece 33 is at the first position, the plurality of spraying holes 32 are communicated with the plurality of adjusting holes 34, and when the aperture adjusting piece 33 is at the second position, the aperture adjusting piece 33 blocks the plurality of spraying holes 32. The shape of the aperture adjusting sheet 33 corresponds to the shape of the bottom of the spraying box 31, and the aperture adjusting sheet 33 is tightly attached to the bottom of the spraying box 31, so that the part of the aperture adjusting sheet 33, which is contacted with the spraying and the bottom, can not be penetrated by water. When the plurality of spraying holes 32 are communicated with the plurality of adjusting holes 34, the spraying water in the spraying box 31 can be sprayed to the outside through the spraying holes 32 and the adjusting holes 34. When the aperture adjusting sheet 33 blocks the spraying holes 32, the solid parts between the plurality of adjusting holes 34 of the aperture adjusting sheet 33 block the plurality of spraying holes 32, and the spraying box 31 cannot spray. The solid portion of the aperture regulating blade 33 refers to a portion of the aperture regulating blade 33 between the plurality of regulating holes 34, and the solid is a concept opposite to the hollowness of the regulating holes 34. The aperture adjusting sheet 33 is slidably connected to the bottom of the shower box 31 and can continuously slide between a first position and a second position. Thus, when the aperture adjusting sheet 33 slides from the first position to the second position, the aperture of the water outlet is continuously reduced because the shielding part of the aperture adjusting sheet 33 for the spray holes 32 is gradually increased; when the aperture adjusting sheet 33 slides from the second position to the first position, the aperture of the water outlet is continuously increased because the shielding part of the aperture adjusting sheet 33 to the spray hole 32 is gradually reduced. Therefore, the size of the water outlet aperture can be conveniently changed by changing the position of the aperture adjusting sheet 33 relative to the bottom of the spraying box 31, so that the spraying flow, the spraying pressure and the spraying distance are changed, and further, the air conditioner can more accurately control the spraying.
Optionally, the aperture adjustment device further comprises a driving motor 35 fixed to the shower box 31 for driving the aperture adjustment sheet 33 to continuously move between the first position and the second position. The position of the air conditioner adjusting sheet at the bottom of the spraying box 31 can be conveniently changed by arranging the motor. The driving motor 35 is arranged, so that the air conditioner can control spraying more conveniently.
