Problems solved by technology

[0005] Although the above traditional fresh air control methods can realize the energy-saving control of fresh air, and can also introduce a reasonable amount of fresh air according to the changes of indoor personnel, there are still two defects: First, for people who stay indoors for a long time The fresh air environment cannot meet its fresh air demand, that is, it is dissatisfied with the constant fresh air environment; secondly, when there are fewer people in the room, the indoor environment will be polluted due to the reduction of fresh air volume.

Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0035] Such as figure 1 As shown, the implementation steps of the fresh air control method of the present invention are as follows:

[0036] Step 1: The fresh air system is turned on, and the adaptation time of the personnel is set, which can be set according to the default program or manually adjusted.

[0037] Step 2: Detect whether the running time exceeds the adaptation time, and run the corresponding program according to the detection result.

[0038] When the operating time of the fresh air system is less than the personnel adaptation time, run the following procedures:

[0039] Step 3.a: The indoor pollutant sensor collects the indoor pollutant concentration ...

Abstract

The invention discloses an energy-saving control method for fresh air, in particular discloses a method for introducing the fresh air reasonably along with change of indoor people, and particularly aims at guaranteeing satisfaction of crowds remaining for a long time in a room. According to the method, a reasonable pollutant control index is selected, people adaptation time and a correction factor a of the pollutant control index are set, then new fresh air can be introduced reasonably along with the change of the indoor people, and fresh air satisfaction and air quality requirements for the crowds remaining for a long time in the room are achieved and satisfied to a large extent on the premise of fresh air energy saving. The method is particularly suitable for places such as a meeting room, a cinema and a theater where indoor people change but a part of people remain for a long time, and can also be used in residual buildings, offices and the like with the same using functions.

Description

technical field [0001] The invention relates to a fresh air energy-saving control method, specifically a method for reasonably introducing fresh air with changes in indoor personnel, focusing on people who stay indoors for a long time and adopting a fresh air energy-saving control method to ensure their satisfaction. Background technique [0002] Reasonable control of indoor fresh air not only creates a good indoor environment, but also saves fresh air energy consumption. According to the design standards and requirements of the fresh air volume, when the indoor occupants change, the demand for the fresh air volume will change accordingly. Therefore, in order to realize the energy saving of the fresh air, the energy-saving control method of the fresh air came into being. In places where the population density changes greatly, the traditional fresh air control methods mainly include the following two: [0003] One: By detecting the number of people in the room, and then calc...
