Detailed Description

The embodiment of the utility model discloses air conditioning system that can dehumidify to solve air conditioning system operation unstability, unreliable problem effectively.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a dehumidifying air conditioning system according to an embodiment of the present invention.

In an embodiment, the present embodiment provides an air conditioning system, specifically, the air conditioning system includes an air guiding passage 1, a refrigeration component, and an adsorption device 3.

The main part of the air conditioning system is a refrigeration component. The refrigeration assembly mainly comprises the evaporator 2, the throttling element 5, the condenser 6 and the compressor 7 which are sequentially connected in series. Wherein the refrigerant liquid after compressor 7 compression evaporates for gaseous in evaporimeter 2, and is evaporating for gaseous in-process, absorbs the heat in the air, and then makes evaporimeter 2 peripheral temperature cooling to cool down to the temperature in the environment.

In the air conditioning system, an air guide passage 1 is further provided, and the air guide passage 1 functions to guide air into the evaporator 2, cool the air by the evaporator 2, and discharge the air from the air outlet. Correspondingly, this evaporimeter 2 should be can be to the stream wind in the wind-guiding passageway 1, the wind body that flows promptly, cool down, so that the water vapor liquefaction or the direct condensation in the stream wind, little drop of water is converged into big drop of water when the liquefaction, and stops near evaporimeter 2, certainly further descend when evaporimeter 2 temperature, then the direct frosting or icing of water vapor, and then make this evaporimeter 2 not only cool down the gas in the wind-guiding passageway 1, can get rid of moisture in the gas simultaneously.

The adsorption device 3 is used for adsorbing water in the flowing air of the air guide channel 1, and it is emphasized that the adsorption is used for intercepting water molecules in the flowing air, namely, reducing the content of the water molecules in the flowing air, and the adsorption is obviously different from heating drying, wherein the heating drying only evaporates liquid water into water vapor, and the drying on the surface does not intercept the water molecules in the flowing air and simultaneously does not reduce the content of the water molecules in the flowing air.

Wherein adsorption equipment 3 sets up between air intake and the evaporimeter 2 of wind-guiding passageway 1 to make external wind follow the air intake of wind-guiding passageway 1 and get into the back, adsorb moisture through adsorption equipment 3 earlier, then flow to the evaporimeter 2 department of wind-guiding passageway 1, with further cooling through evaporimeter 2, make vapor assemble into the big liquid droplet drop of water and held back. It should be noted that, the specific positions of the adsorption device 3 and the evaporator 2 in the air guide passage 1 are not limited herein, and only the air entering from the air inlet of the air guide passage 1 can be adsorbed by the adsorption device 3 before flowing into the evaporator 2 for condensation.

In this but air conditioning system that dehumidifies, when using, refrigeration component starts, 1 air inlet of wind-guiding passageway, the stream wind gets into the back from the air intake, earlier through adsorption equipment 3, adsorption equipment 3 carries out preliminary drying through the adsorption affinity convection current wind of self to reduce the water molecule content in the stream wind, and the stream wind is after adsorption equipment 3, when flowing 2 departments of evaporimeter, because water molecule content has reduced, so can 2 condensation water volumes of greatly reduced evaporimeter or the liquefied water volume. By arranging the adsorption device 3 on the air inlet side of the evaporator 2, the water molecule content in the flowing air flowing to the evaporator 2 is effectively reduced. So that can realize the dehumidification that lower degree required under low temperature environment condition and handle, can make the dehumidification dew point temperature of this system be less than the dew point temperature of former system far away, the temperature range of dehumidification is wideer, simultaneously avoid effectively when low temperature operating mode operation because the moisture of return air is too big, and the operation of frosting of the air conditioning unit that leads to avoids air conditioning system to appear low pressure trip effectively, the phenomenon that refrigeration effect descends, and then fully guarantee the reliability and the refrigeration effect of system. In conclusion, the dehumidifying air-conditioning system can effectively solve the problems of unstable and unreliable operation of the air-conditioning system.

In order to ensure the rapid circulation of the air flowing in the air guide channel 1, the air guide channel preferably further comprises a fan 4 for accelerating the flow of the air in the air guide channel 1, the specific fan 4 can be an exhaust fan arranged at the air outlet of the air guide channel 1 or an air blower arranged at the air inlet of the air guide channel 1, and in order to make the whole cleaner and more convenient to clean, the fan 4 is preferably arranged in the air guide channel 1.
