CABINET WITH CONTROLLED ARTIFICIAL MICROCLIMATE

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, in particular to laboratory equipment. Cabinet contains a glazed working chamber with a glazed front door for observation of biological objects and a double rear glazed wall forming a cavity providing air outlet into the working chamber through a slot in the upper part of the internal glass. Light sources are located on the outer side of the working chamber. Cabinet comprises control unit and air preparation unit consisting of humidifier and cooler, and communicating with working chamber by means of holes in common wall, which is its ceiling and bottom of working chamber, as well as with cavity of double rear glazed wall. Air treatment unit is equipped with flexible air duct, one end of which is tightly connected to outlet pipe of humidifier, and the second end enters the cavity formed by the double rear glazed wall, as well as the screen installed near the second end of the flexible air duct, for protection of flexible air duct against delivery of circulating air into it and provision of unimpeded outlet of humid air. Working chamber is fully or partially glazed by electrically heated glasses, inside of which an infrared heating element is integrated into the surface in the form of a transparent current-conducting coating with a reflecting layer, the heating surface of which radiates heat only towards the working chamber.;EFFECT: device provides reproduction of temperature conditions in the working chamber closer to natural one and reduced consumption of water from the humidifier tank.;1 cl, 1 dwg
