A ventilating air conditioning apparatus has energy efficiency without energy loss associated with ventilation, has high space, saves space, and is low cost. The ventilating air conditioning apparatus has a honeycomb rotor having a function of adsorbing or absorbing contaminants such as carbon dioxide. The honeycomb rotor is disposed in a rotor rotating device having at least a process zone and a desorption regeneration zone. The processed air is passed through the process zone to remove contaminants such as carbon dioxide and the air is supplied. Saturated steam is introduced into the regeneration desorption zone to desorb contaminants such as carbon dioxide and is discharged to outdoors.

A mist generator improves the sterility of blowers having controlled forced air systems. In one embodiment, the mist generator has a chamber adapted to receive a disinfectant adapted for attachment to an output opening of a blower for delivery into the chamber of forced air carrying misted disinfectant. The main body also includes an output duct or aperture adapted for attachment to a second hose which, in turn, is adapted for attachment to an inlet opening of the blower for delivery of disinfectant misted air through internal components of the blower. Alternatively, there is used a disinfectant filter formed as a sterilizing grid having a screen coated with a soft porous surface material impregnated with a liquid disinfectant. The soft porous surface material releases said liquid disinfectant when forced air moves through the filter. In both embodiments, sterile water is introduced to take up residual disinfectant and the vapor captured in a dry filter or desiccant material and removed from the system. The mist generator improves the sterility of the blower to mitigate microbial contamination of forced air delivery systems.

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.

An air filtration apparatus includes a motor, a fan blade, an air filter, a housing, a filter cleaning assembly, and a control panel. A stator of the motor is concentrically mounted within the housing, and the fan blade is concentrically mounted to a rotor of the motor so that the air can be moved via the fan blade. The air filter is externally mounted to a rear panel of the housing to purify incoming air. The filter cleaning assembly is integrated to the air filter and is in fluid communication with the air filter so that the air filter can be cleaned when necessary. The control panel being electrically connected to the motor and the filter cleaning assembly to continuously operates the air filtration apparatus.

An evaporative air cooler for cooling ambient air includes a housing, a tank, a misting structure, a filter structure, and a fan. The housing includes a top panel, a bottom panel, and side panels defining an interior of the evaporative air cooler. The tank is positioned adjacent to the top panel and at least one of the side panels. The tank receives, stores, and releases liquid. The misting structure comprises a mister and a misting structure coupling and creates a mist within the evaporative air cooler. The filter structure has a plurality of filters for absorbing the mist. The fan draws the ambient air into the evaporative air cooler and directs the ambient air through the filter structure and out of the evaporative air cooler. The evaporative air cooler cools the ambient air by at least one of the mist and the filter structure before exiting the evaporative air cooler.

An air scrubber has an electrically driven fan and a drum having a mat forming a closed circulating band spanning a support of the drum. The mat is electrically rotatably driven about a rotation axis, wherein a lower part of the drum is immersed in a water basin. The mat can be removed from the drum by a movement in the axial direction and pushed back on again by a movement in the axial direction.

The invention relates to a filtering apparatus and method for treating polluted indoor air, which can be operated by gas scrubbers, adsorbers, or through the use of a microbial biodegrading medium for polluting gases, wherein said apparatus allows the biofiltration method to be efficient and applicable in indoor spaces. The technical problem of the efficiency of the filter has to do with said filter being able to process the greatest amount of pollutants during a minimum residence time and with a filter bed volume that allows the application thereof in apparatus that have an adequate size for indoor spaces, such as spaces inside the household, i.e., allowing the reactor to operate at maximum capacity without having to increase the size thereof.
