Distributed ventilation system and control method for ward

Abstract

The invention discloses a distributed ventilation system for a ward, which includes a distributed air supply system and a distributed exhaust system. The distributed air supply system includes an air supply power module, an air supply pipeline, a bedside air supply port and a bedside air supply port; The distributed exhaust system includes an exhaust power module and a vertical exhaust pipe. The lower part of the vertical exhaust pipe is provided with a lower air outlet, the middle part is provided with an upper air outlet, and the upper part is provided with an exhaust interface. The outlet and the upper air outlet are located on the front of the vertical exhaust pipe, and the exhaust port is located on the back of the vertical exhaust pipe. At the same time, the invention also discloses its control method. The fresh air can be sent to the patient's activity area and the visiting and accompanying staff's activity area respectively, to meet the sanitary fresh air needs of all kinds of personnel, and to control the air flow without crossing, reducing the probability of cross-infection in the hospital; the modular exhaust structure can quickly carry out Installation, and can be quickly connected to the exhaust equipment, the installation is convenient and fast, the cost is low, and at the same time, it can fully and effectively discharge the peculiar smell of the bathroom.

Description

technical field [0001] The invention belongs to the technical field of ward ventilation, and in particular relates to a ward distributed ventilation system and a control method. Background technique [0002] The indoor thermal environment adjustment of the hospital is to pursue comfort, and the ventilation system is an important means to ensure the health of indoor personnel. At present, the design and operation of ventilation and air-conditioning systems in general wards mainly focus on the control of temperature and humidity in the wards. The ventilation system is reduced to the auxiliary design of the air-conditioning system. The fresh air and indoor air distribution cannot discharge indoor pollutants well, and cannot guarantee the cleanliness of the breathing area of ​​the personnel in the ward and the air safety in the ward. [0003] For a long time, although people are disgusted by the smell in the bathroom, there is nothing they can do about it. As people's requirem...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the bathrooms are ventilated by exhaust fans for top row, and the pollutants in the bathroom are mainly ammonia and hydrogen sulfide, among which ammonia is lighter than air, and hydrogen sulfide is heavier than air, which causes the pollutants in the bathroom to be vertically distributed. There will be vertical distribution in the vertical space, and because the toilet is installed in the lower part of the bathroom, there will be more pollutants in the lower part of the bathroom

None of the existing setting methods can fully and effectively exhaust the bathroom

[0005] Some toilets in old buildings do not even have a ventilation system, or the ventilation system is no longer in normal use, and urgently needs renovation. However, the existing renovation methods require major changes to the building, which takes a long time and costs a lot.
