Embodiment 2

[0031] Embodiment 2, as attached figure 2 The difference between the shown embodiment 2 and the embodiment 1 is that there is one and only one control circuit that controls the opening and closing of the ventilation valves, and the control circuit needs to receive the detection results and control the opening and closing of all the ventilation valves. When the number of rooms is small, the control circuit needs to process less data, but when the number of rooms is large, the data that the control circuit needs to process will be very large. The advantage is that the control circuit will know the air quality of all rooms, and the control circuit can combine all The air quality data of the room is used to control the opening and closing of the ventilation valve respectively. As long as the data is still within the processing range of the control circuit, the air quality regulation will be more reasonable and average.

Abstract

The invention relates to air conditioning systems in buildings, in particular to a central ventilation system. The central ventilation system comprises an air exchange draught fan, an air exchange pipe network enabling the air exchange draught fan to be communicated with single rooms, and air exchange valves arranged at air openings of the air exchange pipe network. The central ventilation system further comprises a control circuit and detection devices, wherein the control circuit is used for controlling the opening and closing degree of the air exchange valves, and the detection devices are used for detecting the air quality of the single rooms and sending detection results to the control circuit. The central ventilation system solves the problem that due to the fact that the inner structure of a building provided with the central ventilation system is complex, the air quality of each room cannot be ensured by an existing central ventilation system. The central ventilation system can ensure the air quality of each room.

Description

technical field [0001] The invention relates to an air conditioning system in a building, in particular to a fresh air system. Background technique [0002] The fresh air system is an independent air treatment system composed of a ventilation fan capable of exchanging and purifying the air, pipes and some accessories. The ventilation fan filters and purifies the outdoor fresh air and transports it to the room through the pipeline, and at the same time removes the indoor dirty air. The air is exhausted outside. [0003] A central fresh air purification and humidification system is disclosed in the patent document CN203323263U, and its claim is "a central fresh air purification and humidification system, including a host and at least one terminal, the host is equipped with a main fresh air suction duct, a main fresh air The air supply duct, the main sewage air exhaust duct, the main sewage air suction duct and the main controller. The terminal is equipped with a terminal fres...
