In addition, the heater 50 can customize the PTC heating amount and the wet film humidifying amount, so as to achieve different control effects, thereby meeting different customized requirements of the market.

The air conditioner has three operation modes of single cooling, electric heating and humidifying, which are respectively explained as follows:

in the single cooling mode of operation, after the air conditioner is turned on, ambient air enters the airflow path of the unit frame 10 under the suction of the fan 60. Specifically, the air passes through the evaporator screen 70 from the wet film 21 and the rear mesh 1221, the both side meshes 1231, the upper opening 1241 to filter the air impurities, and then enters the evaporator 40. The refrigerant in a low temperature state flowing in the fin tubes of the evaporator 40 is present, the temperature of the air is reduced after the air is subjected to heat conduction with the evaporator 40, and the like, and then the air is sent out of the unit frame 10 from the air outlet side (front end) after passing through the heater 50 and the support structure thereof, the fan 60 and the fan guard net, so that the purpose of air refrigeration is achieved.

In the electric heating operation mode, after the air conditioner is turned on, ambient air enters the airflow path of the unit frame 10 under the driving of the suction force of the fan 60. Specifically, the air passes through the evaporator screen 70 from the wet film 21 and the rear mesh 1221, the both side meshes 1231, the upper opening 1241 to filter the air impurities, and then enters the evaporator 40. The air passes through the heater 50 and the support structure thereof, the heater 50 is started to heat the air, and the air is sent out of the unit frame 10 from the air outlet side after passing through the fan 60 and the fan guard net, so that the purpose of heating the air is achieved.

In the humidifying operation mode, after the air conditioner is started, the water pump sends the water stored in the water tank 22 to the water distributor, and the water distributor discharges water to wet the wet film 21. Under the driving of the suction force of the fan 60, part of the ambient air obtains certain water vapor through the wet film 21 fully distributed with the circulating water and passes through the rear mesh 1221; the rest air passes through the evaporator filter screen 70 through the meshes 1231 on the two sides and the upper opening 1241 to filter air impurities, then passes through the evaporator 40 and the heater 50, passes through the fan 60 and is sent out of the unit frame 10 from the air outlet side, and the purpose of air humidification is achieved.

During the three modes, the fan 60 adjusts the rotating speed according to the difference between the set temperature and the indoor environment temperature, if the indoor environment temperature is too high and has a large difference with the set temperature, the fan 60 increases the rotating speed, and the air volume increases along with the increase of the rotating speed of the fan, so that the heat exchange quantity of the evaporator is increased, the rate of reducing the indoor environment temperature is higher, and a high-efficiency and quick refrigeration process is achieved. Similarly, when the indoor environment is too low, a rapid heating process can be achieved. Air can enter the inside of the unit frame from the side meshes, the rear meshes and the top openings, and larger air volume can be obtained.

In summary, the air conditioner with the wet film humidifying device of the present invention has at least the following advantages:

(1) the wet film humidifying device is installed in the outer side of the air inlet side of the unit frame, the size of the unit frame is effectively reduced, a wet film can be taken out through dismounting the fixing screws, the whole machine does not need to be dismounted for maintenance, convenience and rapidness are achieved, the required maintenance space is small, and the maintenance convenience is high.

(2) The evaporator is arc-shaped, U-shaped or V-shaped, the windward area can be increased in the limited installation space, and the problem of achieving larger refrigerating capacity in the limited space can be solved to a certain extent.

The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed should be considered illustrative rather than limiting. The scope of the utility model is, therefore, indicated by the appended claims rather than by the foregoing description. Any changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
