FIELD: heating.
SUBSTANCE: due to change of angle and speed of air exhaust, curtain jet has alternating parameters in height of gates opening, which provides more efficient protection of premises against breakthrough of external air, additional effect is given by automatic optimisation of specified curtain parameters, realised on the basis of microprocessor control controller with account of actual filling of opening. Therefore minimum operational costs are provided for functioning of hot-air curtains with observance of preset requirements to parameters of microclimate in specific industrial premises.
EFFECT: provision of sanitary-hygienic norms in industrial premises at minimum expenses for heating.
