Most models of dryers operate on the principle of the refrigerant circuit : when passing through the cold heat exchanger , the air is cooled to a temperature below the dew point , and it contains water vapor condenses and discharged into the built tank or directly into the sewer . Chilled dry air then passes through the hot heat exchanger , where the temperature returns to previous values or slightly higher , after which air enters the room. Some models of industrial dehumidifiers have an additional heater for heating the exhaust air , which allows them to use at a room temperature to 0 ° C.
High humidity of the room in many cases is undesirable. Limiting factors may be the process conditions , health standards , human well-being . The presence of excess moisture in the room is also one of the main causes of premature damage and destruction of buildings , especially in our climate . For example, in the conditions of winter construction , soaked walls exposed to cold temperatures freeze , concrete and masonry cracked .
Dehumidifiers have been successfully applied to eliminate the above situations by reducing and maintaining a given level of humidity indoors.
There are many modifications of dehumidifiers : mobile , stationary, wall or floor , with a strong , practical and pleasant “home” body design . Each of them finds its application depending on the variant specific use : indoor pool , in construction, in the case of floods, flooding , etc. Continue reading
