New engineering methods in snow removal of roofs by air jets

Abstract

The article provides a description of engineering methods that use the results of scientific research. The example given in the article shows how the use of such methods allows, in comparison with traditional ones, to use for clearing snow from the roofs of a building with a ridge length of 25.5 m instead of three rotary blowers, each weighing 1150 kg, electric motor power of 90 kW and an air capacity of 3132 m3/h, - 2 blowers weighing 204 kg each, electric motor power of 20 kW and productivity of 1110 m3/h. Such a snow removal installation does not require the presence of maintenance personnel on the roof, and no mechanical devices are used on the roof. The installation is controlled remotely.
