The energy-saving purpose is realized, the energy efficiency is improved, the indoor air quality is improved by introducing fresh air, and the air conditioner system with the humidifying function can improve the comfort.

The air conditioner is combined with ventilation and air exchange and indoor humidification, linkage control is performed, and a control strategy of direct mechanical ventilation or combined use of ventilation and humidification is adopted according to indoor and outdoor working conditions, so that the system energy efficiency can be greatly improved, and the purpose of energy conservation is achieved. The control strategy can be controlled according to indoor and outdoor enthalpy values, indoor and outdoor temperatures and indoor pollutant concentration and relative humidity. The humidifying device and the ventilator are integrally designed, the structure is simple and reliable, and the function of direct ventilation or indoor humidification can be realized.

The humidifying device is provided with a water storage tank or a spraying water tank, and can adopt modes such as ultrasonic humidifying, wet film humidifying, spray humidifying, water spray humidifying and the like. The system is composed of an air conditioner, a ventilator and a humidifying structure.

Air conditioners include, but are not limited to, wall mounted, cabinet, window, wall penetrating, multi-split air conditioning units and the like. The ventilator is composed of a direct current motor 11, a fan blade 12 and a shell, is arranged on a wall or a window, has adjustable wind speed and wind quantity, and can realize that fresh air outdoors is sent indoors. The humidifying device is integrated with the ventilator.

Linkage between air conditioner and the ventilation blower can integrated control panel, perhaps adopt bluetooth communication, perhaps adopt modes such as WIFI communication.

The control strategy may employ a comparison based on indoor and outdoor enthalpy and temperature, such as: when the enthalpy value and outdoor temperature of outdoor air are lower than those of indoor air, direct mechanical ventilation is adopted. When the enthalpy value of outdoor air is lower than that of indoor air and the temperature is higher than that of indoor air, the latent heat load in the indoor air is reduced by adopting water spraying humidification; and when the outdoor enthalpy value is higher than that of the indoor enthalpy value, the compressor is started for refrigeration. The preferred control flow is shown in FIG. 8: and starting the machine, and reading parameters such as user set temperature (Tset), outdoor temperature (Tout), outdoor relative humidity (RH out), indoor temperature (Tin), indoor relative humidity (RH in) and the like. And calculating the enthalpy value (outside IH) of outdoor air according to the outdoor temperature and humidity and calculating the enthalpy value (inside IH) of indoor air according to the indoor temperature and humidity by a built-in program. And if the IH is less than the IH, starting the compressor for refrigeration, and operating a compressor control program. If IH outside is greater than or equal to IH inside, then continue to compare T outside with T inside. And if the T outside is less than the T inside, the ventilator is started to perform mechanical ventilation. If the outside T is more than or equal to the inside T, the water injection valve is opened to inject water into the water storage tank or the spray pipe/spray box. And stopping water injection when the indoor relative humidity reaches a preset value (RH preset). And after the operation is carried out for a preset time (such as 30min) according to different modes, if the user is powered off, the shutdown program is operated, and if the user is not powered off, the next step after the startup is carried out again until the shutdown is carried out. The outdoor fresh air with lower temperature is utilized, and the indoor latent heat is reduced through ventilation and humidification, so that the refrigeration load of the air conditioner can be greatly reduced, the energy efficiency ratio is improved, and the air conditioner is energy-saving and environment-friendly. The introduction of outdoor fresh air can also reduce the concentration of indoor pollutants and improve the quality of indoor air.

The humidifying part and the ventilator are designed into a whole, a water storage tank scheme or a spraying scheme can be adopted, and the components comprise a water injection valve 24, a water injection pipe, a water storage tank (or a spraying box or a spraying water pipe), and an overflow hole and an overflow pipe which are arranged on the water storage tank. When the water storage tank is arranged, ultrasonic humidification, wet film humidification, spray humidification or water spray humidification can be adopted, wherein the wet film humidification is shown in the attached drawing 1, and the ultrasonic humidification, the spray humidification and the water spray humidification are shown in the attached drawing 6. When the humidification is needed, the water injection valve is opened, the water storage tank is filled with water, the wet film can absorb the water fully due to the siphon effect, and the humidification and cooling effects can be achieved when wind passes through the wet film. Ultrasonic wave, spraying, water spray are then directly become tiny granule with water, and it is indoor to get into together along with the ventilation, reach the effect of humidification cooling.

When the spraying scheme is adopted, a wet film humidifying mode can be adopted, the spraying water tank is provided with uniform small holes, water can be distributed on the wet film, and a water receiving disc and a water discharging pipe are required to be arranged so as to discharge redundant water. The wet film can be made of materials with good moisture absorption performance, such as a high-molecular wet film, a plant fiber wet film, a non-woven wet film, a resin material, a ceramic material and the like. The spraying water tank can be replaced by a water pipe with small uniform holes.

The water injection valve can be connected to the water pipe, adopts electric control, only fan portion work when carrying out mechanical ventilation promptly, and the water injection valve does not open, and when ventilating, the humidification, the water injection valve is opened and is injected water. The water pump can be used for delivering water in other water tanks to the water injection pipe.

The air conditioner, the ventilation and humidification combined linkage control strategy can also be controlled by temperature, for example, a compressor is adopted for refrigeration under the general condition, the humidification mode is adopted for cooling under the condition of higher temperature and lower humidity, and the direct mechanical ventilation mode is adopted under the condition of lower outdoor temperature (such as night).

The linkage control strategy can also control the indoor pollutant concentration and the indoor relative humidity, for example, when the indoor carbon dioxide concentration, the formaldehyde concentration, the particulate matter PM10, the PM2.5 and the like exceed standards, the ventilator is started to perform mechanical ventilation, and when the indoor relative humidity is lower (for example, lower than 40%), the ventilation and humidification are started. When wet membrane humidification is adopted, except the above mode of directly arranging the wet membrane, a shutter type automatic control structure can be adopted: the wet film is opened when the machine ventilates, and is closed when the machine ventilates, so that the resistance when the machine ventilates can be reduced.
