Hospital Ventilation Control Method and Control System

Abstract

The invention provides a ventilation control method and system for hospitals. The method comprises the following steps that a central data extraction and operation processing platform extracts hourly outpatient visit N from a hospital out-patient registration information management system, and obtains hourly outpatient visits of sub spaces according to the hourly outpatient visit N; the relation model between the hourly outpatient visits and the hourly human traffics of the sub spaces is established finally, and the hourly human traffics M of the sub spaces of a hospital are obtained through calculation; the central data extraction and operation processing platform extracts local outdoor hourly air temperature parameters dynamically from a public meteorology database; a fresh air control strategy predicating model based on indoor air quality and energy conservation is established according to the hourly human traffics of the sub spaces and the temperature parameters; and a fresh air controller controls the rotation speed of a fresh air ventilator according to the fresh air control strategy, and supplies fresh air into a room in real time properly. The ventilation control method and system for hospitals ensure the indoor air quality of hospitals and save energy.

Description

technical field [0001] The invention relates to the field of indoor air environment regulation, in particular to a hospital ventilation regulation method and regulation system. Background technique [0002] As a special place where the susceptible population is highly concentrated and multiple disease sources coexist, the indoor air environment of the hospital has attracted more and more attention. The number of hospital personnel in our country is large, the crowd density is high, the air quality is poor, and the fresh air is not adjusted. The long-term full-load operation of the fresh air fan makes the energy consumption of the fan and the cooling and heat treatment of the fresh air very high. In some hospitals, according to the indoor CO 2 The signal feedback of the concentration regulates the fresh air volume sent to the room by the fresh fan to improve the indoor air quality, while the indoor CO 2 The concentration is mainly through the CO 2 At the same time, in ord...

Problems solved by technology

In some hospitals, according to the indoor CO 2 The signal feedback of the concentration regulates the fresh air volume sent to the room by the fresh fan to improve the indoor air quality, while the indoor CO 2 The concentration is mainly through the CO 2 At the same time, in order to introduce more fresh air into the room when the outdoor temperature is suitable, a lot of temperature sensors must be installed. Therefore, if this method is used to regulate the fresh air, there will be a large number of installed sensors, and the initial investment cost is relatively high. high while CO 2 Most of the sensors have the problems of inaccurate detection data, unreliable detection and failure with the growth of time, and the monitoring location is difficult to determine. It is difficult to use the data monitored by a small number of sensors to represent the air quality level of the large space of the entire hospital. It will lead to the inability to supply a suitable amount of fresh air to the room, resulting in poor indoor environmental quality of the hospital. These are important problems that the current hospital needs to solve urgently.
