An air treatment device includes: a casing having an inlet through which air is drawn, and an outlet out of which the air drawn through the inlet is blown; a blade configured to adjust a direction of the air blown out of the outlet; and a generator configured to generate an antimicrobial element that sanitizes the blade. The blade has a first surface, and a second surface opposite to the first surface. The blade is shiftable between a first position in which the antimicrobial element is provided to the first surface and a second position in which the antimicrobial element is provided to the second surface.

A method and an apparatus are provided that may be applicable to refrigeration assets, including refrigeration plants and cold-storage facilities comprising large numbers of refrigeration assets. The performance of refrigerators and refrigeration devices may be monitored based on temperature and electrical current and other measurements known or deemed to be correlated with refrigeration performance. Refrigeration assets in need of repair may be identified and a repair process may be specified, classified, managed and optimized. The immediate effectiveness and long-term persistence of repairs may be determined over time. The refrigeration assets may be classified according to reliability, performance, make, model and manufacturer. The effectiveness of repairs may be classified based on measured performance results following repairs. Service providers, including organizations, companies or individuals providing repair and other services, may be evaluated for the effectiveness and persistence of repair results using benchmarks and other quantitative evaluation methods.

Provided is an air conditioner including an irradiation unit that irradiates an irradiation area of an indoor unit with ultraviolet rays, a temperature detection unit that detects an ambient temperature of the irradiation unit, and a control unit that controls an irradiation time of the irradiation unit. The control unit controls the irradiation time in accordance with the ambient temperature detected by the temperature detection unit.

An air conditioner includes a control unit that controls an air conditioning operation and controls a maintenance operation to perform maintenance on an indoor unit after the air conditioning operation is stopped, and an operation unit provided for performing a stop operation to stop the maintenance operation. The maintenance operation includes an irradiating operation to irradiate an irradiation area of the indoor unit with ultraviolet rays, and the control unit controls the irradiating operation to continue the irradiating operation even when the stop operation is performed by the operation unit.
