An air circulation and/or purification device for recirculating air and/or removing contaminants from the air which includes a housing having a top with an opening for air intake and a bottom, a fan contained within the housing, and a plurality of air output vents contained within multiple sides of the housing near the bottom of the housing. The bottom of the housing may include a conical shaped portion extending inward from the bottom of the housing or other structures to assist in expelling air from the housing in at least two different directions. The device may also include one or more filters designed to capture and filter out different types of contaminants.

A humidifying device comprising an air duct penetrating axially through the humidifying device, a water tank (201b) for storing water, and a filter element (204b) disposed in the water tank. The water tank (201b) surrounds the air duct. Further disclosed is an air handling system.

A cooling system (20) includes a media exchanger (50), a cooling section (22), and a cooling circuit (120) for circulating a cooling fluid (130) between the media exchanger (50) and the cooling section (22). The media exchanger (50) receives outside air (38) and the cooling section (22) receives return air (32) from and interior space (34). When the cooling fluid (130) circulates into the cooling section (22) via the cooling circuit (120), the temperature of the return air (32) is reduced through indirect heat transfer between the cooling fluid (130) and the return air (32) to produce conditioned air (84). The conditioned air (84) is provided as supply air (46) into the interior space (34). When the cooling fluid circulates into the media exchanger via the cooling circuit, the temperature of the cooling fluid is reduced through direct heat transfer between the cooling fluid and the outside air.

Provided is a dehumidification apparatus with good energy efficiency. A moisture absorbing material (polymeric moisture absorbing material 24), which absorbs moisture and swells at a temperature not higher than a predetermined temperature sensitive point, while shrinking and releasing condensed water at a temperature higher than the temperature sensitive point as a result of phase transition, is formed so as to be divided into a plurality of segments which are made apart from each other during dehydration. A rotation motor (21) is used to move the moisture absorbing material (polymeric moisture absorbing material 24) between a moisture absorption region (14a) and a dehydration region (14b). In the dehydration region (14b), the moisture absorbing material (polymeric moisture absorbing material 24) is heated by the heater (25).

The invention relates to the air environmental control technology field and discloses an environmental control unit including a shell, cooling device, a water pipe, a heating device, a control device, a sensor, a safety protection device, an air purification device and a humidifying device set in the shell. The invention combines the efficient circulation heating supply system with the air purification device. During the rapid heating of air, the cold-hot air convection is used to accelerate the air circulation purification and humidification treatment process. The sensor detects the real-time indoor air quality and adjusts the temperature, humidity and air quality by further control of the system according to the environmental parameters. The invention uses the air convection circulation to effectively improve the air purification and humidification efficiency with very high practical value. And it is of important positive significance for the development of water heating industry.
