An approach to solving the problem of optimizing the climate control process in a ship`s room using elements. The specific microclimate of the ship`s premises is determined by their isolation from external atmospheric influences, small volumes and a relatively large number of people, as well as the saturation with various mechanisms, systems, devices, various cargoes transported and the features of the marine climate. Presented technical solutions at the stage of elaboration and the implementation of algorithms based on modern components assume performance of the specified requirements for normal operation of ventilation systems and conditioning of the working area. The article presents the algorithm of the methodology and calculation of elements of system of ventilation and air conditioning systems with rapidly varying air flow in one zone of production facilities. With the aim of improving the accuracy, speed and efficiency, the integrated system that combines proper ventilation, air conditioning and a quantitative regulation of intake air.

One Hundred Ninety Six automobile buyers were surveyed in Chicago, Illinois to determine user understanding of symbols and words commonly found on climate (heater and air conditioning) controls in today's automobiles. This survey was part of a larger market research project. Subjects were administered a paper and pencil test and were asked to identify symbols and words randomly located on a page by recording their answers on a blank line beside the symbol. They were then asked to operate climate controls labeled either with words or symbols following which they rated the ease of identifying the controls. The buyer population that was surveyed contained primarily import car buyers due to the nature of the product being researched. Recognition rates ranged from 92% to 47%, indicating that most of the symbols were relatively well understood except for the rear defrost, air conditioning, and defrost/floor air flow symbols. However, subjects also responded that words were preferred over symbols in ease of identifying functions by almost a 2 to 1 margin in preference except for the air distribution modes, where symbols were preferred over words 61% to 48%.
