Snow removal system for flat roofs, comprises snow height sensor and heat exchanger between main heating system and secondary heating system for roof

摘要

#CMT# #/CMT# The system comprises a closed loop for circulating hot water supplied from the central heating boiler (1) via a circulation pump (4). A level sensor (17) is used to measure the height of the snow on the roof and once a height of at least 1 cm is reached, a sensor is sent to a control box (16), which in turn sends signals to the boiler and pump in order for hot water to be circulated through a heat exchanger (7) linking the central heating system (primary system) with the secondary heating system for the roof. This secondary system contains a circulating mixture of water and glycol. #CMT#USE : #/CMT# For clearing snow from flat roofs of buildings, including houses and commercial premises. #CMT#ADVANTAGE : #/CMT# The roof is prevented from collapsing under the weight of snow. The system is not activated by heavy rainfall. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the snow removal system. 1 : central heating boiler 4 : circulation pump 7 : heat exchanger 16 : control box 17 : level sensor.
