Air purifier based on principle of vapor condensation and adsorption and air conditioning apparatus having same

An air purifier based on a principle of vapor condensation and adsorption, comprising:

• an air blowing device;
• a humidifying devices;
• a cooling device;
• and
• a heating device;
• wherein the humidifying device is used to increase a content of vapor in air, and the cooling device is used to reduce a temperature of the air;
• wherein the humidifying device, the cooling device, and the heating device are connected to form a passage for air circulation, and under an action of the air blowing device, the air to be purified flows in via an inlet of the passage for air circulation, and when the air is cooled at the cooling device, the vapor in the air is condensed and adsorbs pollutants in the air during condensation, and the pollutants, together with at least one of:
• droplets and/or solid particles formed by the condensation of the vapor, drip from the air to be purified under an action of gravity, so as to be removed from the air to be purified;
• wherein the heating device is used for heating the air, such that air discharged from an outlet of the passage for air circulation satisfies a pre-set temperature threshold.
