Microwave gas-discharge device OVOD-1a sanitizing indoor air

Abstract

Abstract A new UV scanning system OVOD-1a for the indoor air environment, based on high-performance microwave gas-discharge lamps developed at GPI RAS, is described. The first experiments demonstrating the air-cleaning capabilities of UV equipment were carried out. It is shown that in laboratory rooms used for the stay of livestock bred in agriculture, the energy cost of almost complete purification of the air environment from viral and fungal components is of the order of 10−2 kW × h/m3. B acter ial sanita tio n o f the laboratory p re mise s o f the research physical Institute is carried out with an energy cost of ≍ 3 10−3 kW×h/m3. The fundamental physical processes underlying microwave UV lamps, which are the main component of the OVOD-1a sanitation system, are discussed.
