Embodiment 1

[0035] see Figure 1-2 As shown, the present invention is an air-conditioning fresh air replacement system based on indoor air detection, including an air supply unit, which is arranged on the indoor side wall and the indoor top, and delivers fresh air to the room; an exhaust unit, which is arranged on the indoor side Above the wall, and discharge the high-temperature dirty air in the room; heat exchange unit, the heat exchange unit is set between the air supply unit and the exhaust unit, and heats the fresh air delivered by the air supply unit and the high-temperature dirty air discharged by the exhaust unit Exchange; control unit, the control unit is used to control the switch state of the air conditioner, switch the air supply state and exhaust state; the acquisition unit is used to periodically obtain the indoor and outdoor temperature and humidity, CO2 concentration and harmful gas concentration respectively, and transmit this data To the judging unit; the judging unit ju...

Embodiment 2

[0039] On the basis of the first embodiment above, as Figure 4 As shown, the temperature pre-adjustment module includes a cooling device; the cooling device includes a cooling duct 2 wrapped around the air supply duct 1 of the air supply unit; the cooling duct 2 is a circulation duct; the cooling duct 2 is connected to a circulation pump 3, when the temperature pre-conditioning When the regulating module heats the fresh air, the circulation pump 3 is started to cool the liquid in the cooling pipe 2 to the air supply pipe 1; When the temperature needs to be lowered, the liquid in the cooling pipe 2 is immersed in the air supply pipe 1 to cool down the fresh air, which affects normal use. The inner wall of the cooling pipeline 2 is equipped with a liquid level gauge 5 for detecting liquid; the cooling pipeline 2 is also provided with a valve 4 for adding liquid. When the liquid level gauge 5 detects that the liquid level is lower than the preset value, new liquid for cooling. ...

Embodiment 3

[0044] The present application also provides a method for an air-conditioning fresh air replacement system based on indoor air detection, including the following steps: Step A01: The acquisition unit periodically acquires indoor and outdoor temperature and humidity, CO2 concentration and harmful gas concentration, and transmits this data to Judging unit, the judging unit compares the indoor and outdoor data, and controls the air conditioner through the preprocessing unit to perform preprocessing; step A02: after the air conditioner is turned on for N minutes, the acquisition unit continues to periodically detect the indoor and outdoor temperatures respectively, and passes the judgment After the unit is judged, the temperature pre-adjustment module pre-cools the fresh air delivered by the exhaust unit, or preheats the fresh air delivered by the exhaust unit through the heat exchange unit; wherein, the exhaust unit also includes the delivered air when it is working. The sterilizi...

Abstract

The invention discloses an air conditioner fresh air exchange system and method based on indoor air detection, and relates to the technical field of air conditioners. The air supply unit is arranged on the indoor side wall and the indoor top. The exhaust unit is arranged above the indoor side wall; the heat exchange unit is arranged between the air supply unit and the air exhaust unit; the control unit is used for controlling the on-off state of the air conditioner and switching the air supply state and the air exhaust state; the acquisition unit is used for periodically acquiring indoor and outdoor temperature and humidity, CO2 concentration and harmful gas concentration respectively; and the judging unit is used for judging whether the indoor CO2 concentration or the harmful gas concentration exceeds a preset value or not according to the data acquired by the acquiring unit. Through the action of the temperature and humidity pre-adjusting unit and the heat exchange unit, the problems that when an existing fresh air exchange system works, the indoor temperature rises or drops too fast, harmful substances and bacteria are likely to be inhaled, and body health is affected are solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a fresh air replacement system and method for an air conditioner based on indoor air detection. Background technique [0002] When the amount of carbon dioxide is low, there is no harm to the human body, but when it exceeds a certain amount, it will affect the breathing of the human body, causing difficulty in breathing, dizziness and nausea, and even suffocation and death. If the human body stays in a closed air-conditioned room for a long time, due to the poor air flow in the confined space, it is easy to cause the concentration of carbon dioxide to be too high, causing the human body to feel uncomfortable. In order to reduce the discomfort caused by high carbon dioxide concentration in the room, a fresh air system is usually installed in the room, and the fresh air system is started or stopped according to the high or low carbon dioxide concentration, so a...
