Negative pressure isolation ward ventilation system and debugging method thereof

Abstract

The invention belongs to the field of negative pressure wards, and particularly relates to a negative pressure isolation ward ventilation system and a debugging method thereof. The negative pressure isolation ward ventilation system involves a negative pressure isolation ward, and a ventilation system and an exhaust system which communicate with the negative pressure isolation ward; a ventilationvolume adjusting valve is arranged between the ventilation system and the negative pressure isolation ward; an exhaust volume adjusting valve is arranged between the exhaust system and the negative pressure isolation ward; and a negative pressure gauge is arranged in the negative pressure isolation ward. According to the system and the method, in the debugging process, whether the designed and selected ventilation system and exhaust system meet the use requirement of the negative pressure isolation ward or not can be clearly checked, and the negative pressure value and the ventilation frequency of the negative pressure isolation ward can be rapidly, effectively and accurately adjusted.

Description

technical field [0001] The invention belongs to the field of negative pressure wards, and in particular relates to a fresh air system for a negative pressure isolation ward and a debugging method thereof. Background technique [0002] In order to deal with sudden infectious disease outbreaks, provide a safe working environment for medical staff. More and more tertiary hospitals are building negative pressure isolation wards. By configuring specific devices, the internal pressure of the ward is lower than the external pressure, ensuring that the air polluted by infectious disease bacteria will not leak to the outside, and providing physical protection for medical staff. [0003] The architectural design code for infectious disease hospitals stipulates that the negative pressure isolation ward should adopt a fresh air DC air-conditioning system. Therefore, for the negative pressure isolation ward, the air volume flowing through the negative pressure isolation ward is the fresh...

AI Technical Summary

Problems solved by technology

Therefore, improper debugging will lead to low negative pressure value or insufficient ventilation in the negative pressure isolation ward, which does not meet the requirements of the negative pressure isolation ward in the specification, and thus cannot effectively play the role of the negative pressure isolation ward. How can it be faster, more efficient? It is a technical problem to be solved by those skilled in the art to debug the negative pressure isolation ward more conveniently and accurately

[0006] At the same time, using the existing debugging method, the fresh air volume entering the negative pressure isolation ward increases with the increase of the negative pressure value, and the fresh air volume is often greater than the design value. In order to debug a suitable negative pressure value, the exhaust air volume can only be adjusted to a larger state, which causes a waste of energy

If it is due to improper design, the negative pressure value and ventilation times required by the negative pressure isolation ward will also be unable to be debugged. How to ensure the effect of the negative pressure isolation ward while achieving energy-saving operation, and how to quickly find improperly designed factors and solve the same problem It is a technical problem to be solved by those skilled in the art
