FIELD: ventilation and air-conditioning systems and installation of associated items of equipment.
SUBSTANCE: proposed device includes supply and exhaust systems connected in parallel with drum-type revolving air dehumidifier containing layer of grain adsorbent by means of air ducts. Supply system is provided with bypass air duct for outside air which is located behind fan and before and after revolving air dehumidifier; device is also provided with surface air cooler connected with cold water producing system on base of multi-stage direct and indirect cooling of air. Units of supply and exhaust systems are mounted on articulated frame whose axis of rotation coincides with its vertical or horizontal axis of symmetry.
EFFECT: possibility of using device all year round; enhanced ecological safety; low cost.
