Problems solved by technology

[0027] Therefore, the current in the indoor air exceeds the set temperature or CO 2 After the concentration is higher than the benchmark, the ventilation system starts to start, which makes the people in the room feel uncomfortable from time to time, and it is difficult to adjust the air purity to an appropriate state in a short time, effectively making the people in the room feel comfortable and living. difficulty

Embodiment Construction

[0062] Referring to the accompanying drawings, an embodiment of the air volume control method of the ventilation system of the present invention will be described in detail as follows.

[0063] image 3 It is a flow chart of the air volume control method of the ventilation system of the present invention, as image 3 As shown, in the case of power supply, when the indoor unit is operating in the cooling or heating mode, the user judges whether the current temperature, indoor / outdoor temperature, set temperature and CO 2 Concentration is only arbitrarily changed to maintain the purity of indoor air in advance, but operates temperature control mode and concentration control mode according to the purity of indoor air.

[0064] That is, even if the current indoor air purity is good, after a certain period of time, the indoor air purity may increase or decrease due to smoking or a sharp increase or decrease in the number of people in the room.

[0065] At this time, the user sets...

Abstract

The present invention provides an air quantity control method of air exchange system. Said method includes the following stages: stage of checking the set mode which is air purification mode or not; and the stage of forcedly operating and controlling air supply fan air quantity and air discharge air quantity according to the checked result, if said set mode is air purification mode, and making air quantity of air supply fan and air discharge fan be correspondent to the air quantity of the described air purification mode. Said air quantity control method also includes the steps of checking various set modes including air purification mode, indoor temperature/outdoor temperature/set temperature control mode and CO2 concentration control mode, etc.

Description

technical field [0001] The present invention relates to an invention of a ventilation system, in particular to an invention related to an air volume control method of the ventilation system. Background technique [0002] The air in a general closed space increases with time due to the respiration of living organisms, and the CO 2 The content of gas is also increasing, hindering the breathing of living organisms. [0003] Therefore, when most people stay in a small space such as an office or a vehicle, a ventilation system is needed to replace the indoor polluted air with outdoor fresh air. [0004] The above-mentioned ventilation system drives the air supply fan to introduce outdoor air, and after the introduced air is cooled to a temperature close to the temperature of the indoor air through the heat transfer exchanger, it is introduced into the room through the air supply unit. In addition, the exhaust fan is driven to draw indoor air into the exhaust unit, and the sudde...
