Abstract

The invention provides a centralized flue variable air volume device and a variable air volume control method for high-rise residence kitchens. The system comprises a centralized flue penetrating floors of a high-rise residence, a plurality of kitchen exhaust branch pipes located in the floors of the high-rise residence correspondingly, communicating with the centralized flue and provided with range hoods, a roof draught fan communicating with the top end of the centralized flue, a plurality of signal collecting devices and a signal processing device. The signal collecting devices are arranged at the positions of the range hoods correspondingly so that after the states of the range hoods are recognized, position signals and start and stop signals of the range hoods can be collected and sent out. The signal processing device is connected with the signal collecting devices and the roof draught fan through a signal transmission channel so that after the position signals and the start and stop signals are received, statistics can be made on the positions and the number of the started range hoods, and a frequency conversion control instruction is sent to the roof draught fan. The centralized flue variable air volume device and the variable air volume control method solve the problem that in an existing centralized flue, the total exhaust volume design, calculation and running energy consumption is large and the problem about running optimization.

Description

technical field [0001] The invention belongs to the field of building structures, and relates to a residential kitchen smoke exhaust system and a control method. Background technique [0002] At present, in order to ensure the effective purification of cooking fumes in high-rise residential kitchens and the appearance of residential building facades, existing residential kitchens generally use centralized flue smoke exhaust. However, in high-rise residential buildings, the time when residents on each floor use the kitchen is not uniform, which is very random, which in turn causes the variability of the exhaust air volume of the centralized flue system. [0003] In view of this, how to design a centralized smoke exhaust system according to the characteristics of residential use, and make proper operation adjustments, so that the system can operate efficiently, has become the goal and direction of current technology to seek breakthroughs. Contents of the invention [0004] ...
