Problems solved by technology

[0003] Existing dehumidifiers include compression refrigeration type, solid adsorption rotor type, liquid absorption type, etc. The latter system is very complicated and bulky, at least including absorber (dehumidifier), evaporator (regenerator), heat exchange It is only used in industrial and commercial environments. Most of the homes and public places are compression refrigeration. Its principle is similar to that of compression air conditioners. It freezes the air below the dew point and condenses out Moisture, the cost is high, generally 3 to 5 thousand yuan, the minimum price is not less than 1000 yuan, and there is Freon polluting the environment, it will be banned internationally
The cost of the solid adsorption rotary type is much higher, and the service life is very short, so it is rarely used in civil places
In addition, even in hot tide areas, there are not too many weathers with high humidity throughout the year. Wealthy consumers can afford to spend a lot of money to configure dedicated dehumidifiers, and it is not a bad idea to keep them closed for most of the year. It is a big waste, so although the air humidity brings great troubles to people, only a small number of families can use special dehumidifiers
[0004] For this reason, many people try to assign a dehumidification function to the air-conditioning fan that is closed in season, and add a complete set of compression refrigeration and dehumidification system. Because the humidification and cooling system must be retained, the manufacturing cost of the whole machine is higher than that of a simple dehumidifier. It is more difficult to be accepted by consumers, and the problem of air humidity still troubles people

Embodiment 1

[0066] See figure 1 , 2 , a multifunctional air-conditioning fan capable of dehumidifying air, including a casing 10, a fan assembly 20 placed in the casing, an evaporation system 30, and an electric control component 60; the evaporation system 30 includes a wet curtain 31, a storage device for liquid working medium The liquid storage tank 33 and the moisture absorbent regenerating device 34, wherein the wet curtain 31 is placed in the air duct of the fan, and the liquid storage tank 33 is placed under the wet curtain. The air-conditioning fan can work in humidification and cooling conditions and dehumidification conditions. In the humidification and cooling conditions, the working medium in the liquid storage tank 33 is water, and in the dehumidification conditions, the working medium in the liquid storage tank 33 is moisture agent. The regenerating device 34 is used for dehydrating, concentrating and regenerating the hygroscopic agent that has absorbed a large amount of wa...

Embodiment 2

[0073] See image 3 , 4 , 5, a kind of multifunctional air-conditioning fan that can dehumidify air with built-in regeneration device is basically the same as embodiment 1, and the difference lies in:

[0074] A. The regeneration device 34 is a built-in regeneration device 341 placed in the machine, which includes an electric heating element 3411, placed in the air duct of the fan assembly 20 and located on the air inlet side of the wet curtain 31, Figure 4 It is an I-type structure, and the electric heating element is placed in the air outlet duct of the fan. Figure 5 It is a type II structure, and the electric heating element is placed in the air inlet duct of the fan. The type I is beneficial to reduce the temperature inside the machine. When the fan heater is running, the wet curtain paper can be removed and moved out of the machine; High air volume, and the heating element can be removed and moved out of the machine; the heating element 3411 is a PTC heating component...

Embodiment 3

[0079] See Image 6 , a multifunctional air-conditioning fan capable of dehumidifying air with a built-in regeneration device is basically the same as Embodiment 2, except that:

[0080] The fan assembly 20 is a reversible cross-flow fan 22. When the multi-functional air-conditioning fan works in regeneration and heating conditions, the fan rotates forward, such as Figure 4 , the wet curtain 31 and the electric heating element 3411 are in the air outlet duct of the fan; when the multifunctional air-conditioning fan works in the humidification and cooling condition, the fan is reversed, and the wind direction of the fan is opposite to the regeneration condition, as Image 6 As shown, the wet curtain 31 is located in the air inlet duct of the fan; in the dehumidification mode, the direction of the fan is not limited. Generally speaking, when the wet curtain is in the air inlet duct of the fan, the air volume is larger, and it is more suitable for cooling in summer.

Abstract

The invention provides a multifunctional air condition fan capable of dehumidifying air and a dehumidifying method thereof, belonging to a device for adjusting the temperature and the humidity of indoor air. The multifunctional air condition fan comprises a shell (10), a fan component (20), an evaporating system (30) and an electric control part (60), wherein the evaporating system comprises a wet curtain (31), a liquid storing box (33) and a hygroscopic agent regenerating device (34); when under the work condition of wetting and temperature reducing, the liquid storing box (33) stores the water; and when under the work condition of dehumidifying, the liquid storing box stores the hygroscopic agent. The regenerating device has an internal type, an external type and a manual type. The invention realizes the multifunctions of wetting and temperature reducing, dehumidifying, cooling and heating with the cost which is similar to that of the existing evaporating type cold fan. The invention integrates the dehumidifying device and the existing air condition fan into a whole, which have complete season complementation and inverse working principle, thereby reducing the manufacture cost of the special dehumidifying device and eliminating the resources waste caused by the seasonal idling. The invention can achieve the cooling effect without a compressor and Freon, and can take the residual heat of the kitchen and the solar energy as cooling energy, thereby being an innovative technology of environment protection and low carbon economy for families and public places, and having higher popularization and use value.

Description

technical field [0001] The invention relates to an indoor air temperature and humidity adjustment device, in particular to an evaporative cooling fan, especially a multifunctional air-conditioning fan capable of dehumidifying air. Background technique [0002] The existing evaporative cooling fan is an indoor air-conditioning device for evaporative cooling of water, commonly known as an air-conditioning fan. Absorb the heat of vaporization, and the air sent by the air conditioner fan will cool down due to the heat of vaporization released in the machine. The whole working process is an isenthalpic change, that is, the air only cools down without cooling, because increasing the humidity increases the latent heat, and the enthalpy value remains unchanged. . This product can only be used in summer in relatively dry areas, but not in winter and humid areas. It is a seasonal regional product. In most parts of our country, there are mildewy rainy weather in winter and spring, an...
