Reviews the technology for using non-isothermic jets for ventilation. In three parts - 1) Discusses the physical problems related to the calculation of ventilating jets, 2) Deals with the peculiarities of ventilating rooms with cold jets (ranging from -25degC to plus 5degC), 3) Discusses methods of calculating the parameters of the thermal microclimate with ventilated rooms, primarily velocity and temperature of jets.

KEYWORDS: Ventilation, air jets, calculating, rooms, microclimate, temperature.
