The invention relates to the technical field of air conditioner, in particular to a ceiling cassette smart combined air conditioner.
With the consumption upgrade of air quality in household space, traditional household central air conditioners cannot meet the demands of high-quality home life. The traditional household air conditioners are either too cold or uneven overheating, which is hard to provide healthy and comfortable feelings. Additionally, the operation cannot take advantage of the natural factors to automatically switch to the energy-saving mode, resulting in high energy consumption. The household central air-conditioning systems on the market all work independently, e.g., air conditioners handle air temperature only, dehumidifiers handle air humidity, fresh fans handle fresh air and purification functions. These independent appliance systems cannot be integrated and coordinated, and because the outdoor temperature and humidity cleanliness changes greatly in the morning, middle and evening, the automatic variable work cannot be achieved. It is impossible to intelligently control various changing state parameters in a timely manner, and not possible to adapt to changes. Therefore, the most comfortable air environment can not be provided.
In view of this, a ceiling cassette smart combined air conditioner is proposed, which integrates the multi-functional centralized treatment of the indoor air quality, including air temperature, humidity, freshness, cleanliness, ultraviolet disinfection, negative oxygen ions, odor removal, and formaldehyde removal, etc. AI artificial intelligence control system is adopted to meet the indoor air conditioning effects of constant temperature, constant humidity, constant oxygen, constant pressure, constant quietness and constant cleanliness.

The working principle of the multi-functional smart combined air conditioning cassette, according to the working order from the outside to the inside of the machine.
Control of the fresh air outlet and damper, return air outlet and damper: The indoor controller automatically controls the opening of the fresh air damper of the smart combined air conditioning cassette according to the detection concentration of indoor CO2, and the opening determines the entering amount of fresh air. The opening of the indoor return air damper is automatically adjusted to determine the amount of the return air, and the control methods of the fresh air damper and the return air damper are inversely proportional. According to the indoor air CO2 detection parameters, different control command is issued, which can automatically realize various fresh-return air demands such as partial fresh air + partial return air, full fresh air, full return air, etc. According to the indoor air PM2.5 detection parameters, instructions are sent out to control the fan speed to achieve the speed and efficiency requirements of filtering indoor and outdoor PM2.5.
In a word, the multi-functional smart combined air conditioning cassette can perform I/O automatic control according to the detection and setting of PM2.5, CO2, temperature, humidity, formaldehyde, TVOC, etc. The all-variable design ideas that vary from person to person, adapt to local conditions and time can be realized, which are energy-saving as well as healthy and comfortable, achieving the ideal healthy, comfortable and energy-efficient indoor environment for the human body.
