Referring to fig. 6, the indoor unit of the air conditioner includes an indoor unit casing 501, an indoor unit filter 502, an indoor unit heat exchange fin 503, an indoor unit heat exchanger copper pipe 504, an indoor unit fan 505, an electromagnetic valve 506, a water replenishing pipe 507, an indoor unit water storage tank 508, a liquid level sensor 509, a condensed water drain pipe 510, a condensed water pan 511, and an air conditioner fan blade 512, which are respectively disposed in the indoor unit casing 501. The air conditioner fan blade 512 is rotatably connected to the indoor unit housing 501. The spray water pipe 108 is connected to the indoor unit water storage tank 508. The indoor unit heat exchanger copper pipe 504 is arranged in the indoor unit heat exchange fin 503 in a penetrating manner, and the heat exchanger fin 503 is arranged adjacent to the indoor unit fan 505. The indoor unit filter screen 502 is disposed on the indoor unit heat exchange fin 503, and is located between the indoor unit heat exchange fin 503 and the indoor unit casing 501.
The indoor unit water storage tank 508 is located below the indoor unit fan 505, the condensed water pan 511 is located below the indoor unit heat exchange fins 503, and two ends of the condensed water drain pipe 510 are respectively communicated with the indoor unit water storage tank 508 and the condensed water pan 511. The condensed water pan 511 is used for collecting condensed water from the indoor unit of the air conditioner, and discharging the collected condensed water to the indoor unit water storage tank 508 through the condensed water discharge pipe 510.
The indoor unit water storage tank 508 is also connected with a water replenishing pipe 507, and the electromagnetic valve 506 is arranged on the water replenishing pipe 507. The liquid level sensor 509 is arranged on the indoor unit water storage tank 508 and is used for detecting the liquid level height in the indoor unit water storage tank 508, and when the liquid level of the indoor unit water storage tank 508 is detected to meet the requirement, the electromagnetic valve 506 is closed to stop adding water into the indoor unit water storage tank 508; when the water quantity in the indoor unit water storage tank 508 is detected to be insufficient, the electromagnetic valve 506 is opened, and clean tap water is supplemented into the indoor unit water storage tank 508 through the water supplementing pipe 507.
When the outdoor unit of the air conditioner operates in winter, the low voltage pulse power supply 208 is first turned on, and moisture absorbed from the air by the moisture absorbent material layer 203 in a standby state is discharged by electro-osmosis to regenerate the moisture absorbent material layer 203. Typically, the moisture absorbed in the moisture absorbent material is low, and the machine can be started up for several minutes. After the outdoor unit fan 111 is turned on, when outdoor air passes through the filter screen 101 from the outside, larger impurities in the air are filtered by the filter screen 101. The filtered air is blown through the electro-osmotic absorbent assembly 102 and the absorbent material layer 203 dries the air to reduce the relative humidity of the air. The dried air is then blown against the heat exchanger fins 110 and exchanges heat with the refrigerant within the heat exchanger copper tubes 112.
In this embodiment, the relative humidity of the dried air is low, and the moisture absorption material layer 203 generates physical absorption heat when absorbing moisture, so that the dew point temperature of the air is still lower than the surface temperature of the heat exchanger, and condensation or frost is not generated on the surfaces of the heat exchanger fins 110 and the heat exchanger copper tubes 112, thereby suppressing the occurrence of frost formation in the outdoor unit of the air conditioner. In winter, the spray assembly 103 is in an off state.
Meanwhile, an electric field in the horizontal direction is periodically applied to both sides of the moisture absorbing material layer 203, the liquid water adsorbed by the moisture absorbing material layer 203 will migrate toward the negative electrode inert mesh electrode 206 under the action of the electric field force, and the water will be continuously collected in the water-repellent layer 202, and finally will drop into the water-repellent tank 109 along the water-repellent channel 205 under the action of gravity, and flow out from the water-repellent opening 106 of the water-repellent tank 109.
When the outdoor unit of the air conditioner operates in summer and when the outdoor condensing temperature is detected to be too high, the spraying component 103 needs to be started, and the low-voltage pulse power supply 208 also needs to be switched on to carry out moisture absorption and regeneration on the electro-osmosis moisture absorption component 102. Then, the outdoor unit fan 111 is turned on, air flows through the filter screen 101 and the electro-osmotic moisture absorption unit 102 in sequence, and the relative humidity of the air dried by the electro-osmotic moisture absorption unit 102 is reduced. Under the condition of lower relative humidity of air, the spraying rate of the atomizing nozzle 104 and the evaporation rate of the spray are improved, the evaporation latent heat of the spray is larger than the adsorption heat generated by the moisture absorption material, and the cooling effect is improved.
In addition, when the outdoor unit of the air conditioner stops operating in summer, the spraying assembly 103 may be turned on to clean the heat exchanger fins 110, thereby preventing dirt attached to the heat exchanger fins 110 from affecting the heat exchange effect of the heat exchanger. Similarly, the moisture adsorbed in the moisture absorbing material layer 203 is gathered on one side of the negative electrode inert mesh electrode 206 under the action of the electric field, and finally drops into the drain groove 109 below along the drain channel 205, and is discharged from the drain opening 106 from the drain groove 109.
When the spraying assembly 103 works, the water pump 105 is turned on, the water in the indoor unit water storage tank 508 is conveyed into the spraying pipeline 402 along the spraying water pipe 108 and is sprayed out through the atomizing nozzle 104, and the filter 107 arranged in front of the water pump 105 filters impurities in the water to prevent the water pump 105 from being blocked. Wherein, the water atomized but not evaporated and the sewage for self-cleaning the heat exchanger fins 110 drop into the drain groove 109 below and are discharged through the drain opening 106.
The water in the indoor unit water storage tank 508 mainly comes from indoor condensed water, and during the operation of the air conditioner, the condensed water in the condensed water pan 511 enters the indoor unit water storage tank 508 through the condensed water drain pipe 510 for storage. When the water in the indoor unit water storage tank 508 is insufficient, tap water is used for supplying. If the position for installing the air conditioner is closer to a tap water pipe, the water replenishing pipe 507 can be directly connected with the tap water pipe, at the moment, the electromagnetic valve 506 is opened, and tap water enters the indoor unit water replenishing tank 508 through the water replenishing pipe 507; when the liquid level sensor 509 detects that the liquid level in the indoor unit water storage tank 508 reaches a predetermined level, the solenoid valve 506 is closed and the supply of tap water is stopped to prevent overflow. When the installation position of the air conditioner is far away from the tap water pipe, an artificial water replenishing port can be arranged on the water replenishing pipe 507 to replenish water artificially.
The air conditioner outdoor unit utilizes the electroosmosis effect to reduce the temperature and inhibit frost, combines the electroosmosis technology and the moisture absorption material, reduces the relative humidity of air in winter, inhibits frost formation, and solves the problem of frost formation of the air conditioner outdoor unit from the source under the condition of not changing the complexity of a system; in summer, before the condenser is subjected to spray cooling, the air is subjected to dehumidification treatment to reduce the relative humidity so as to improve the spray rate and the evaporation capacity, thereby improving the cooling effect. In addition, the outdoor unit of the air conditioner does not need high-temperature regeneration of the moisture absorption material any longer, and the moisture in the moisture absorption material is migrated and discharged by directly adopting an electroosmosis technology so as to achieve the aim of regeneration, so that the cost and the energy consumption are reduced, the steps are simplified, the effect of cooling the environment where the outdoor unit is located in summer operation is improved, and the frosting phenomenon on the surface of the heat exchanger of the outdoor unit in winter operation is relieved.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
