FIELD: air conditioning and ventilation systems.
SUBSTANCE: proposed warm air curtain consists of housing with cylindrical and flat section, tangential fan impeller installed in housing, drive, electric heaters secured on side partitions of housing, air flow guide, and flow divider. Housing is made curvilinear between cylindrical and flat sections, and axis of tangential impeller is displaced towards side of flat section of housing. Electric heaters are secured on side partitions of housing coaxially to cylindrical section of housing. Flow guide is secured on side partitions of housing, being made in form of L-shaped member.
EFFECT: provision of improved manufacturability of construction, increased convective heat transfer.
