Dehumidifier dehumidification method classification 1. Heating, cooling and dehumidification: heating the air to increase the temperature of the air, so as to reduce the relative humidity, but the moisture content of the air does not change. Therefore, the moisture of the air cannot be removed from the root. 2 , freezing dehumidification: the humid air is cooled below its dew point temperature, the moisture in the humid air is condensed and precipitated, reducing the moisture content of the air, and then heating through the reheat condenser to reduce the relative humidity of the air, in the dew point When the temperature is 8 to 12 ° C or higher, the efficiency is relatively high. 3. Solid adsorption dehumidification: The ceramic fiber impregnated with the microporous moisture absorbent is processed into a honeycomb runner, and the runner is divided into two zones by a highly sealed filler, one is an air treatment zone, and the other is a runner regeneration zone. The two zones are continuously switched and the dehumidification structure is simple, and the low dew point temperature of Zui can reach -60 °C. 4 , liquid absorption dehumidification: dehumidifier is to absorb the moisture in the humid air by spraying lithium bromide, lithium chloride and other salt solution, the dehumidification process is dependent on the lower surface vapor pressure of the dehumidification solution, the dew point temperature can be reduced -20 ° C, but the equipment is large, and the absorption fluid must be replaced regularly 5 , compression dehumidification: first compress the humid air, and then cool, remove the moisture in the air, suitable for small air volume occasions.
An Oropharyngeal Airway is a medical device called an airway adjunct used to maintain or open a patient's airway. It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing. When a person becomes unconscious, the muscles in their jaw relax and allow the tongue to obstruct the airway. An oropharyngeal airway has four parts: the flange, the body, the tip, and a channel to allow for passage of air and suction. Oropharyngeal airways come in a wide range of sizes.
