The illustration shows a generic example of a box plot with the maximum, third quartile, median, first quartile, and minimum values labeled. The relative vertical spacing between the labels reflects the values of the variable in proportion.
Respirator Types Two basic types of respirators are: â¢ air-purifying; andâ¢ supplied-air respirators. Air-purifying respirators remove airborne contaminants such as particles, toxic vapors, and/or gases.
In condensers the refrigerant gives up the heat that is has absorbed in the evaporator. There are three main types of condensers: air cooled condensers, water cooled condensers and evaporative condensers. There are four main parts of refrigerating and air-conditioning systems, these are: compressor, condenser, throttling or expansion valve and the evaporator.
