Abstract

Conventional air-conditioning equipment on the market fails to meet the technical requirements when used for thermohygrometric control and of levels of ammonia of the interior ambient air of the microenvironmental cabinets. These conventional pieces of equipment are sized merely for macroenvironments and for human comfort, not meeting the requirements of animal testing laboratories. The proposed equipment would provide the correct sizing of volumes of air in the air- conditioning system for heat exchanges between the interior and the exterior air, as well as the safe dilution of the ammonia vapors generated by the animals. Also envisaged is the sizing of a piece of equipment with air condensation, autonomous working, totally automatic, microprocessed, easy to regulate from the point of operation, with visual temperature and relative humidity indicators, including batteries for warming, humidifying and filtering of air, electro-electronic controls, silent working and of small dimensions, able to cope with a maximum of two microenvironmental cabinets. Installation is envisaged for a window and/or hole in the wall, with ease of operation and preventative and/or corrective maintenance. The result is important for the enhancement of animal testing processes and for the guaranteed quality of the experiments and/or scientific results. (AU)
