Abstract
The invention discloses a control method of a ventilation air conditioner based on CO (Carbon Monoxide) detection. The method comprises the steps of firstly arranging a CO2 (Carbon Dioxide) concentration detector, a CO concentration detector and an alarm indoors, then comparing the detected CO2 concentration with a predetermined CO2 concentration threshold value, and comparing the detected CO concentration with a predetermined CO concentration threshold value; controlling the ventilation air conditioner and the alarm to work according to the comparison result. By applying the method, the carbon monoxide poisoning can be actively prevented; when the carbon monoxide concentration exceeds the standard, the ventilation is actively implemented, and an alarm is given for caution.
Description
Technical field
The present invention relates to field of air conditioning, particularly relate to a kind of control method of the air exchangeable conditioner based on CO detection.
Background technology
Product when anthracemia is carbonaceous material incomplete combustion causes poisoning through respiratory tract suction.Carbon monoxide is gas that is colourless, tasteless, odorless, and every carbon or carbonaceous material burn when oxygen is insufficient, all can produce carbon monoxide.When using wood stove, coal stove, as ventilating system is not smooth, gas fire and gas water heater improper use especially in recent years makes anthracemia greatly increase.Because carbon monoxide is colourless, tasteless gas, so be referred to as " reticent killer ".Human body sucks after carbon monoxide, often has no consciousness, even to occur after serious symptom still somehow, thus continues to be in the carbon monoxide environment of high concentration, until dead.
Along with the progress of society, increasing people have selected and live easily, and a lot of people uses natural gas.If natural gas burns insufficient, be easy to just produce carbon monoxide, in China, the event of anthracemia is of common occurrence, how to take precautions against anthracemia pay close attention to by increasing people.
Air-conditioning is used by increasing family, and along with the progress in epoch, the function of air-conditioning also gets more and more, wherein ventilatory is the up-to-date technology be used on air-conditioning, ensures that family has fresh air, prevents the generation of air conditioner disease, use more comfortable, more rationally.
But existing air-conditioned ventilatory only passive being used for change to fresh air, initiatively can not prevent anthracemia.
Patent " a kind of air exchange system of central air-conditioning " (application number: 201320053659.4 applyings date: 2013-01-31) discloses a kind of air exchange system that can carry out the central air-conditioning of the introducing ratio of the outer new wind of automatic control room according to the density of indoor temperature, humidity and personnel, thus realizes utilizing the energy of outdoor new wind to reach energy-conservation object.Controller in this patent utilizes the information of indoor temperature transmitter, indoor humidity sensor, outdoor temperature sensor, outside humidity sensor to calculate the enthalpy of room air and outdoor air, utilizes CO
2concentration sensor obtains the CO of room air
2concentration; And according to the CO of the comparison of the enthalpy of the mode of operation of air-conditioner set, room air and outdoor air, the temperature of room air, the temperature of outdoor air and room air
2concentration controls the aperture of air returning valve, exhaust valve, mixer selector valve, new air-valve, blow valve, and utilizes outdoor fresh air to assist to improve human comfort as much as possible, reduces refrigeration or the heating power consumption of air-conditioner set, reaches energy-conservation object.
The ventilation of this patent is only used to the freshness adjusting room air, makes human comfort the highest, initiatively can not prevent anthracemia.
Whether a lot of air-conditioning can both have people in sensing chamber now, is often adopt infrared detecting device, and after detecting whether indoor have people by such device, and then whether control air-conditioning operates and stop.
But, when adopting infrared detecting device, be easy to, because detect dead angle, check less than some local, easily produce erroneous judgement, and then affect the control of air-conditioning.
Summary of the invention
Technical problem to be solved by this invention is for defect involved in background technology, provides a kind of control method of the air exchangeable conditioner based on CO detection.
