The air-in passage, the first haze removing module, the second haze removing module, the third haze removing module and the air-out passage are connected in order. The air treatment unit provided by the present invention is capable of not only completely recovering cold energy or heat energy of indoor air, but also effectively treating indoor and outdoor PM2.5 and harmful gases.

A multifunctional storage system includes a storage chamber and a machinery chamber provided on a side of the storage chamber. The system further includes a dehumidification part dehumidifying circulating air flowing in the storage chamber; a circulating air inlet and a circulating air outlet enabling the storage chamber and the machinery chamber to communicate; and a circulation filter unit supplying moisture to circulating air supplied to the storage chamber via the circulating air inlet.

A water-cooled fan includes a body having an air inlet and an air outlet; a fan unit corresponding to the air inlet or the air outlet; an installation slot placed between the air inlet and the air outlet; and a water supply unit disposed above the installation slot. A method for controlling a multifunctional fan includes configuring a functional space and providing a water supply unit at a top end of the functional space; optionally providing a honeycomb or an air filter unit in the functional space; and when the honeycomb is provided in the functional space, providing, by the water supply unit, dampening water for the honeycomb. The present invention can selectively achieve the effect of air humidification or air purification by using a honeycomb or an air filter unit as needed, and the water-cooled fan of the present invention has high intelligence. A multi-purpose set reduces the cost.

It is an Evaporative Humidifier Air Purification combo unit performing the functions of both cool mist evaporative air humidifier as well as the air purifier. The optional attachments make it easy for the consumers to make use of any of the functions it is capable of performing. It even solves the problem of degradation of performance and material life prevalent in conventional standalone air purifier units. The evaporative humidifier is motor driven and is provided with proprietary HEPA quality nano membrane with high chemical stability, waterproof, water vapor permeability, windproof, breathable, acid and alkali resistant, anti-corrosion and anti-bacteria functions etc. membrane used in combination with humidifier cooler pads. On using the water tank, the setup performs the function of air humidifier using the air sucked from the wick using the fan and aiding the evaporation of water in the tank. While on replacing the water tank with the air cover, the same fan sucks air through wick and blows the purified air upwards in consonance to the mode i.e. High, Medium or Low.

Trickle bodies for the air conditioning of, in particular, animal housings, that possess only partially latticed layer elements. Trickle bodies are formed of a plurality of sandwiched layer elements that, in known trickle bodies, are formed of corrugated and completely latticed plastics foil. The trickle bodies formed of such layer elements possess a relatively low stability and a limited evaporation capacity. The plastics-formed layer elements of the instant invention are produced by injection molding, allowing layer elements having corrugation heights of more than 12 mm to be formed. Such trickle bodies are more stable, enable a high evaporation capacity and are, moreover, also less permeable to light.

An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) system air filter for a building ventilation system. The HVAC system air filter comprises a supportive frame configured to orient the HVAC system air filter within the building ventilation system. A composite filter medium retained within the supportive frame comprises a cotton gauze portion and an electrostatic portion. The cotton gauze portion is configured for treatment with a filter oil composition to enhance airflow and filtration of air flowing through the composite filter medium. The electrostatic portion is configured to electrostatically attract and agglomerate airborne molecular contaminants and volatile organic compounds (VOCs) as small as 0.001 microns in diameter. In some embodiments, the composite filter medium comprises substances configured to release a fragrance into air passing through the composite filter medium.
