Introduction

The ventilation modernization section is made taking into account the following requirements:

1. SNiP 2.04.0591 * "Heating, ventilation and air conditioning";

2. SNiP 230199 "Construction climatology";

3. SNiP 2.08.0289 * "Public buildings and structures";

4. SanPiN 2.2.4.54896 "Hygienic requirements for microclimate of utility rooms."

3. technological solutions adopted

Design solutions for ventilation systems are shown on sheet 2 of the general data.

4. operation of ventilation systems

The procedure for cleaning and disinfection of ventilation systems is established by a number of documents, the main one is resolution No. 4 of the 27.08.2004 "On the organization and conduct of cleaning and disinfection of ventilation and air conditioning systems," order No. 107 of the 12.08.2004 "On the organization of control over the cleaning and disinfection of ventilation and air conditioning systems" as well as methodological guidelines and annexes to it. It is necessary to keep a log of work on disinfection of ventilation systems, approved form.
