Abstract
The utility model relates to an energy-saving ventilation device intelligently controlled according to concentration of carbon dioxide. The energy-saving ventilation device is composed of a carbon dioxide sensor (1), a carbon dioxide sensor module (2), a programmable logic controller (PLC) (3), a frequency converter (4) and a fan (5). The carbon dioxide sensor (1) is used for detecting the concentration of the carbon dioxide in indoor air. The carbon dioxide sensor module (2) converts analog quantity signals transmitted by the carbon dioxide sensor (1) into digital signals capable of being read by the PLC (3). The PLC (3) compares the digital signals transmitted by the carbon dioxide sensor module (2) with a set value, calculates corresponding frequency signals and transmits the frequency signals to the frequency converter (4). The frequency converter (4) controls motor operating frequency of the fan (5). The energy-saving ventilation device can control the operating frequency of the fan according to the concentration of the carbon dioxide of indoor environment, and therefore operating cost of a ventilation system can be lowered, and the purpose of energy conservation can be achieved.
Description
Technical field
The utility model relates to fan controller, relates in particular to a kind of ventilated energy-saving device according to the gas concentration lwevel Based Intelligent Control.
Background technology
At present, various places such as blower fan extensive use and hotel, market, factory.The power type selecting of blower fan mainly is to decide according to careat and the device requirement of ventilation, exhaust system correspondence, fan operation is normally according to fixing pattern and power operation, not will consider indoor environmental aspect and air quality, more not will consider gas concentration lwevel, this has just caused still full speed running of blower fan under the good situation of IAQ, causes the waste of the energy.。
Summary of the invention
The objective of the invention is to a kind of ventilated energy-saving device according to the gas concentration lwevel Based Intelligent Control, it can control the frequency of fan operation according to the gas concentration lwevel of indoor environment, under the situation that satisfies the IAQ requirement, reduce the power of fan operation, thereby reduce the operating cost of system, reach purpose of energy saving.
Carbon dioxide is the important indicator of IAQ, the utility model is with the foundation of the gas concentration lwevel in the room air as fan operation, reduce the power of ventilating system motor by intelligent speed-regulating, reduce the cost of fan operation effectively, be particularly useful for blower fan for a long time in the ventilation of power frequency state operation, the reducing energy consumption of exhaust system.
The technical solution of the utility model is specially: a kind of ventilated energy-saving device according to the gas concentration lwevel Based Intelligent Control is made of carbon dioxide sensor, carbon dioxide sensor module, PLC cyclelog, frequency converter, blower fan; Carbon dioxide sensor is used for carbon dioxide in air concentration in the sensing chamber; The carbon dioxide sensor module is transmitted the analog signals of coming in carbon dioxide sensor and is converted into the readable data signal of PLC cyclelog; The PLC cyclelog transmits data signal and the setting value of coming in the carbon dioxide sensor module and compares, and calculates corresponding frequency signal and is sent to frequency converter; The motor rotation frequency of Frequency Converter Control blower fan.
The PLC cyclelog transmits data signal and the setting value of coming in the carbon dioxide sensor module and compares, and judges that the PLC cyclelog will be transferred to higher frequency values of frequency converter when concentration is higher than setting value, and the Frequency Converter Control motor accelerates operation; Judge that concentration is lower than when setting value, the PLC cyclelog will be transferred to lower frequency values of frequency converter, and the Frequency Converter Control motor runs slowly.
The utility model can apply to ventilate, exhaust system, it can control the frequency of fan operation according to the gas concentration lwevel of indoor environment, under the situation that satisfies the IAQ requirement, can reduce the power of fan operation, reduce the operating cost of ventilation, exhaust system effectively, be conducive to energy-conservation.
