Harmful biological contaminants are treated using plasma fields. The inventive techniques offer improved results over existing devices and methods.

An AHU comprises a cabinet, a heat exchanger and a blower. The cabinet has an air inlet opening and an air outlet opening, panels are provided on sides of the cabinet forming an air flow path for air flowing through the air handling unit between the air inlet opening and the air outlet opening. The heat exchanger is disposed in the air flow path and adapted to conduct heat exchange between air passing through the air flow path and a working medium flowing in the heat exchanger. The heat exchanger includes an inlet header for supplying the working medium and an outlet header for collecting the working medium. The heat exchanger is slanted with respect to a side of the cabinet such that the inlet header and the outlet header extend through one of the sides of the cabinet for providing access to the inlet header and the outlet header from the one of the sides of the cabinet. The blower is vertically disposed relative to the heat exchanger in the cabinet for forcing air to flow through the air flow path.

Provided are: a vehicle cooling apparatus and a residential and office cooling apparatus, which are improved so as to prevent offensive odors and respiratory diseases by killing fungi and bacteria inside of a cooling part by means of hydrogen generated by electrolyzing the water condensed at the cooling part of the cooling apparatus; or a cooling apparatus and an air conditioning apparatus having a health-beneficial hydrogen generation device added thereto in which bacteria do not propagate since hydrogen is mixed and supplied to the interior air by means of a heat pump such that air quality is improved and the quality-improved air is supplied.

Provided is a large-capacity ultrasonic space-sterilizing humidifier using an aqueous hypochlorous acid solution, wherein contaminants in humidified air are prevented from becoming included in humidifying water, the hypochlorous acid concentration, in the humidified air is sufficiently maintained and a space-sterilizing effect is adequately exhibited.

The ultrasonic space-sterilizing humidifier comprises a storage tank 2 storing an aqueous solution of hypochlorous acid, an ultrasonic generator 3 installed inside the storage tank 2, generating a hypochlorous acid-containing mist, an air duct 8 extending upwards from the ultrasonic generator 3, blowing means 4 for blowing the mist into the air duct 8, water-catching means 9 provided near the bottom end of the air duct 8, for collecting water droplets that have become adsorbed onto the inside wall of the air duct 8, and a discharge tube 11 mounted on the water-catching means 9, by which adsorbed waiter droplets are discharged to the outside.
