Fresh air conditioner control system and control method thereof

Abstract

The invention provides a fresh air conditioner control system and a control method thereof. An air conditioner comprises an indoor unit body and a fresh air device, the fresh air device is arranged outside or inside the indoor unit body in a linkage manner, and is used for providing outdoor fresh air to the room, the control system comprises an environment detection device, a cloud server and a controller, and is arranged in the indoor environment, the environment detection device comprises an air quality detector, a temperature detector and a data transmission interface, and the controller obtains the air quality difference value and the indoor temperature difference value which are calculated by the cloud server, if the air quality difference value is larger than zero, the controller controls the fresh air device to run, if the air quality difference value is smaller than or equal to the zero, the controller controls the fresh air device to be turned off, if the indoor temperature difference value is larger than zero, the controller controls the air conditioner to run in a refrigeration manner, if the indoor temperature difference value is smaller than zero, the controller controls the air conditioner to carry out heating running, and if the indoor temperature difference value is equal to zero, the air conditioner does not run.

Description

technical field [0001] The invention relates to the field of intelligent air conditioners, in particular to a fresh air air conditioner control system and a control method thereof. Background technique [0002] As we all know, air pollution is becoming more and more serious. When indoor air pollution reaches a certain level, it will affect people's breathing. In mild cases, it will cause difficulty in breathing, dizziness and nausea, and in severe cases, it will cause people to suffocate and die. If the human body stays in a confined space 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. This phenomenon is especially serious in rooms using air conditioners, because users will close the doors and windows to ensure the heat exchange effect when using the air conditioner. [0003] In order to reduce the discomfort caused by the high carbon dioxi...

Problems solved by technology

[0004] In the prior art, the fresh air replacement method is started or stopped solely according to the high or low carbon dioxide concentration. Although the carbon dioxide concentration in the room can be controlled within a reasonable range, it is easy to introduce fresh air with an unsuitable outdoor temperature into the room during the fresh air replacement process. , so that the temperature of the room changes too much, the temperature comfort decreases, and it cannot provide a suitable environment for the human body.
