[0002] For high-end residential products, especially villas, central air conditioners are currently mostly used to adjust the indoor air environment.

[0003] The current residential air conditioning system architecture mostly adopts the overall architecture of indoor unit + outdoor unit. As an electric device, the indoor unit has practical problems such as high operating noise, easy leakage of circulating medium, inconvenient maintenance and repair. Especially for large-area villa buildings, the number of indoor devices often reaches more than a dozen, which is very cumbersome to control and operate, with poor overall comfort and low operating energy efficiency of individual devices.

[0004] In addition, the maintenance and repair of indoor unit equipment requires workers to enter the room for operation, which constitutes a certain degree of intrusion into the household environment and personal privacy of the residents and may cause adverse effects. Summary of the Invention

The unit main body is provided with a fresh air inlet, an indoor exhaust outlet, an indoor air supply outlet and an indoor return air inlet;

[0007] Inside the unit main body, there are an initial filter, an electrostatic filter, a dehumidification module, a heat exchange module, a static pressure equalizing chamber, a secondary filter module, and a supply fan connected in sequence with the fresh air inlet. The supply fan is connected to the indoor air supply outlet;

[0008] A humidification module is arranged inside the static pressure equalizing chamber;

[0009] Inside the unit main body, there is a pre-temperature adjustment module connected to the indoor return air inlet. The pre-temperature adjustment module is respectively connected with a heat exchange module and an indoor exhaust valve. The indoor exhaust valve is connected to the indoor exhaust outlet;

[0065] In the above embodiments, the outdoor temperature and the outdoor PM2.5 concentration are the priority control indicators, and the indoor humidity and the indoor carbon dioxide concentration are the auxiliary control indicators, so as to coordinate the energy consumption and the indoor environment guarantee.

[0066] As a specific control method for controlling the indoor humidity through the dehumidification module and the humidification module, when the indoor humidity is lower than the target range, the dehumidification module stops operating and the humidification module starts operating; when the indoor humidity is higher than the target range, the dehumidification module starts operating and the humidification module stops operating; when the indoor humidity is within the target range, the dehumidification module stops operating and the humidification module stops operating.

[0071] When the outdoor temperature T < -10°C, if the outdoor PM2.5 concentration ρ ≤ 35 μg / m 3, the electrostatic filter is closed, and the fresh air volume is adjusted according to the indoor carbon dioxide control concentration of 1000 ppm; if the outdoor PM2.5 concentration is 35 < ρ ≤ 75 μg / m 3 , the electrostatic filter is turned on in the medium - efficiency mode, and the fresh air volume is adjusted according to the indoor carbon dioxide control concentration of 1200 ppm; if the outdoor PM2.5 concentration is 75 < ρ ≤ 150 μg / m 3 When it is between, the electrostatic filter is turned on in the high - efficiency mode, and the fresh air volume is adjusted according to the indoor carbon dioxide control concentration of 1500 ppm; if the outdoor PM2.5 concentration ρ ≥ 150 μg / m 3 When it is between, the electrostatic filter is turned on in the high - efficiency mode, the secondary filtration module is turned on, and the fresh air volume is adjusted according to the indoor carbon dioxide control concentration of 2000 ppm, but the fresh air volume is not less than 30% of the supply air volume.

[0072] In the above - mentioned embodiments, by controlling the electric field intensity of the electrostatic filter, the switching between the medium - efficiency mode and the high - efficiency mode is achieved, where the electric field intensity in the high - efficiency mode is higher than that in the medium - efficiency mode.

[0073] In some embodiments, the strategy for adjusting the supply air volume of the heat - exchange module 4 according to the indoor temperature is that when the indoor temperature t > 20°C, the supply air volume is 60% of the rated air volume; when the indoor temperature 5 ≤ t ≤ 20°C, the supply air volume is 40% of the rated air volume; when the indoor temperature t < 5°C, the supply air volume is 20% of the rated air volume; at this time, the heat - exchange module 4 does not perform refrigeration or heating, and the supply air volume is achieved by controlling the rotation speed of the supply fan 2.
