Abstract

The invention relates to a control method and device of a fresh air conditioning system and the fresh air conditioning system, and belongs to the technical field of fresh air conditioning control. The number of people in a target room is obtained through the outdoor carbon dioxide concentration and the indoor carbon dioxide concentration of the target room, and the fresh air supply amount of the target room is obtained based on the obtained number of people; a temperature and humidity comparison result of the target room is obtained by using the indoor temperature and humidity of the target room and indoor temperature and humidity set values; and based on the obtained fresh air supply amount, opening degree control is conducted on a fresh air valve, used for adjusting the fresh air supply amount of the target room, of the target room, and frequency control is conducted on a fan coil unit, used for conducting heat exchange on air in the target room, of the target room through the obtained temperature and humidity comparison result. By means of the method and the device, the energy efficiency of the fresh air conditioning system can be improved, meanwhile, the indoor air quality can be improved, and the comfort of the indoor environment is improved.

Description

technical field [0001] The application belongs to the technical field of fresh air air conditioning control, and in particular relates to a control method and device for a fresh air air conditioning system and the fresh air air conditioning system. Background technique [0002] In the related technologies, while pursuing a comfortable indoor temperature environment, consumers' voices for health are getting higher and higher, and fresh air air conditioners have emerged as the times require. The fresh air air conditioning system is an air conditioning system integrated with a fresh air system. [0003] In order to meet the normal operation in most environments at the initial design stage of the fresh air air conditioning system, the maximum value of the typical daily hourly load is usually used as the room load value when calculating the load, and it will be multiplied by a certain surplus coefficient after calculation , and select related equipment that can cover its paramete...
