INTENDED USE
PRINCIPLE OF WORK
The basis of the technical solution for recuperation ventilation is the countercurrent, with a
continuous thermal cycle, a copper heat exchanger, which makes it possible to form two
different-directed airfl ows in the volume of one cylinder (Fig. 1).
Warm exhaust air that is removed from the room, passing through a copper heat exchanger
transmits its warmth to the counter stream of fresh air from the outside.
The system allows recover heat, which contributes to increasing the overall recuprration rate
and allows maintain the optimum humidity mode in the room. Taking into account that air
streams are separated and regulated at levels “infl ow” – “exhaust”», there is no mixing of
different-directional air fl ows.
High velocity of the fl ow with suffi cient heat transfer effi ciency ensures removal of up to
90% moisture in a dispersed state, preventing its condensation and freezing of the heat
exchanger at low ambient temperatures.
DESCRIPTION OF THE SYSTEM
Ventilation systems “PRANA-150”, “PRANA-200C”, “PRANA-200G” are intended for creation
and maintenance of healthy microclimate in premises.
These systems are recommended for use in residential and public facilities (apartments,
houses, offi ce premises, educational establishments, kindergartens, etc.).
Monoblocks of the centralized anti-current infl ow-exhaust ventilation.
PRANA-150 and PRANA-200 belong to the category of innovative and reliable products
aimed at creating and maintaining a healthy microclimate in premises of various functional
purposes.
High energy effi ciency and signifi cant air exchange capabilities make it possible to apply
these ventilation systems for organizing domestic ventilation.
Technologically, the system is a monoblock with high-effi ciency counter-current
copperrecuperator ready to use in accordance with the design and assembly tasks and
conditions.
